Ultra low cost carriers like Sun Country and Frontier can be wonderful for your wallet and brutal on your extras. Seat selection, bags, even talking to a human can come with a fee. For frequent or even semi-regular flyers, the right co-branded credit card can blunt a lot of that pain. The challenge is choosing the card that genuinely saves you money instead of just adding another annual fee. This guide looks at two of the most useful options for budget travelers in the United States today: the Sun Country Visa Signature credit card and the Frontier Airlines World Mastercard.

The Cards at a Glance
Both the Sun Country Visa Signature and the Frontier Airlines World Mastercard are co-branded airline credit cards aimed squarely at budget-conscious travelers. Each carries an annual fee around the upper double digits, typically about the cost of a couple of checked bags on a round trip, and both reward you most for sticking with their airline. The big appeal is that these cards can undo some of the most frustrating fees baked into the ultra low cost carrier model.
The Sun Country Visa Signature is issued by Synchrony Bank and is tied to the Sun Country Rewards program. Recent card materials indicate an annual fee of about 89 dollars, tiered earning up to 5 points per dollar on Sun Country purchases, and additional benefits like baggage savings and chances to earn or maintain Sun Country Plus status through spend and flying. Points generally do not expire as long as the account remains open and in good standing, which is important if you only fly a few times a year.
The Frontier Airlines World Mastercard is issued by Barclays and plugs into the Frontier Miles program. Current public and inflight offers have been touting welcome bonuses of around 50,000 to 70,000 miles after a low minimum spend or even after first purchase, plus reward multipliers that can reach 5 miles per dollar on Frontier purchases with additional bonuses for elite members. The annual fee is often in the 79 to 99 dollar range, and long-running perks include free checked bags, priority boarding and an award redemption fee waiver when you use the card to pay taxes and fees on mileage tickets.
On paper they look similar: mid-range annual fee, boosted earning on airline purchases, and airline-fee relief. In practice, the way those perks are structured can produce very different savings depending on how you travel, where you live, and how many people you usually fly with.
Fees, Earning Rates and Welcome Bonuses
For budget flyers, the first test is simple: will this card’s rewards and perks reliably outweigh the annual fee within a year of normal use? To answer that, you need a rough understanding of the fee structure and earning power of each product, not just the flashy sign-up bonus.
Recent disclosures for the Sun Country Visa Signature show an annual fee of about 89 dollars and variable purchase APRs that sit in the high teens to high twenties, broadly in line with many airline cards. There is no introductory 0 percent APR on new purchases and balance transfers normally incur a percentage fee. The big financial win is concentrated on Sun Country spending, where you can earn up to 5 Sun Country Rewards points per dollar, with fewer points on everyday purchases. Because point valuations on these proprietary programs tend to hover around one cent each for economy flights, 5X on tickets or bag fees can effectively give you around 5 percent back in travel value.
The Frontier Airlines World Mastercard posts a similar annual fee bracket, usually around 89 dollars, but introduces a more aggressive earn structure on its home carrier. A typical current offer advertises 5 miles per dollar on purchases at FlyFrontier.com, 3 miles per dollar at restaurants, and 1 mile per dollar on most other spending. Some offers layered on extra miles for Frontier elites, taking the rate up to around 15 miles per dollar on Frontier tickets. In practice, that means a 250 dollar flight booked directly with the airline could generate 1,250 to 3,750 miles before any elite bonuses, enough to move you noticeably closer to a domestic reward seat.
Where Frontier tends to stand out is the welcome bonus. Recent public and inflight brochures have been quoting bonuses near 50,000 to 70,000 miles after first purchase or after spending around 1,000 dollars within 90 days. For a budget traveler who can plan a few trips within the next year, that can translate into two or more round-trip domestic economy tickets on off-peak dates. Sun Country’s bonuses are more modest and change more often, but generally provide at least one free or heavily discounted flight after meeting the initial spend requirement. Either way, if you time your application before a period of higher spending, such as holiday travel or a move, you can use that bonus to erase significant airfare costs.
Bag Fees, Seat Fees and How the Perks Actually Save You Money
The real question for most readers is not how many points you can stack up, but how effectively these cards shield you from add-on fees on basic fares. On ultra low cost airlines, bags represent a major cost center, particularly for families and sports travelers hauling skis, golf clubs or camping gear.
Sun Country charges for almost all checked and overhead bags, with prices that rise the closer you get to departure. Online pre-purchase can keep a standard checked bag in the 30 to 40 dollar range one way on many routes, but paying at the airport can push that well past 50 dollars. The Sun Country Visa Signature softens this by providing a specific baggage benefit. On many itineraries, primary cardholders receive a significant discount on the first checked or overhead bag when booked online through Sun Country, often around half off compared with the standard online bag price. For a Minneapolis based traveler flying to Phoenix with a single checked bag, that could mean paying around 18 to 20 dollars instead of 35 to 40 if the discount is fully applied.
Crucially, Sun Country’s baggage perk can extend to traveling companions on the same reservation when the cardholder pays for the trip. Imagine a family of four flying from Minneapolis to Fort Myers for spring break, each needing a checked bag. A normal online bag purchase for four people could easily reach 280 dollars round trip. With cardholder baggage benefits applied to each traveler, that total might drop by roughly a third to a half, enough to cover the card’s annual fee in a single vacation.
Frontier takes a different approach that can be even more valuable for travelers who consistently check bags. Current benefit language explains that Frontier Airlines World Mastercard holders, when they link their card to their Frontier Miles account and use it to pay for the ticket, are eligible for two free checked bags on Frontier operated flights for themselves. Authorized users and companions generally need to meet specific conditions, but the core idea is that the primary cardholder can check substantial luggage without incremental fees.
Consider a Denver based traveler who flies Frontier four times a year to visit relatives in Orlando, always with a large suitcase and a box of gifts. Without the card, a single checked bag might add 40 to 60 dollars each way depending on when it is purchased, or roughly 80 to 120 dollars per round trip. Over four trips, that quickly becomes 320 to 480 dollars in bag fees. Holding the Frontier card and booking correctly, those checked bags can be free, easily justifying the annual fee and then some before you even factor in miles earned on the flights. For anyone who checks bags more than once or twice a year, the Frontier baggage perk alone can be worth multiple times the cost of membership.
Route Networks and Who Each Card Really Fits
No co-branded airline card is worth the annual fee if you rarely fly that airline, and this is especially true with ultra low cost carriers that operate focused, non-hub networks. The first question to ask is simple: does this airline have a meaningful presence at your home or most-used airports?
Sun Country’s network centers on Minneapolis Saint Paul, with seasonal and leisure heavy routes to warm weather destinations such as Phoenix, Las Vegas, Orlando, Fort Myers and several Mexican beach cities. If you live in Minnesota or western Wisconsin and typically look for budget flights to sunny destinations once or twice a year, Sun Country may be one of your cheapest regular options. In that case, the Sun Country Visa Signature card’s baggage savings, point earning and the ability to keep your points from expiring just by holding the card all become much more compelling. A Minneapolis family that does a winter beach escape and a summer long weekend each year might easily generate enough Sun Country flights to make regular use of the perks.
Frontier, by contrast, has grown a sprawling network with dense presence in Denver, Orlando, Las Vegas, Philadelphia and several secondary airports across the country. Frontier also runs creative point to point routes between mid-size cities like Cincinnati and San Juan or Cleveland and Cancun, plus a large selection of seasonal and international options. If your local airport regularly shows Frontier fares at or near the top of every budget search and you are willing to fly them several times a year, the Frontier Airlines World Mastercard becomes an obvious candidate.
A traveler based in Orlando who frequently hops to Chicago, Atlanta or San Juan, for example, might find multiple Frontier flights each week at attractive base fares. In that scenario, the ability to earn 5X miles on those bookings, avoid paying for checked bags, and waive some award redemption fees can turn Frontier into a long-term value play rather than a one off gamble on the cheapest ticket.
There is also a geographic sweet spot where both airlines appear regularly. Midwestern travelers, in particular, may find that they alternate between Sun Country and Frontier depending on schedule and price. In that case, choosing between cards becomes less about route access and more about your personal fee profile: how often you check bags, how many people you travel with, and whether you care about perks like priority boarding or elite shortcuts.
Everyday Spending, Elite Shortcuts and Non-Flight Benefits
Although both cards are most powerful when used directly with their partner airline, many travelers also want a card that pulls double duty for groceries, dining or gas without feeling like they are giving up too much value. Here the differences narrow, and neither product competes head-on with the top general travel cards in the market.
The Sun Country Visa Signature tends to assign lower earning rates to non-airline categories, often around 1 point per dollar on general spending and slightly higher rates for certain travel or dining purchases. That means that while you could put your weekly grocery trip or streaming subscriptions onto the card, the effective return in cents per dollar will often lag behind a flat rate cash back card. Where it does shine is in keeping your Sun Country Rewards balance alive and in reaching Plus status through spend. Current program rules allow members to earn Plus status either by taking around 10 qualifying Sun Country flights or by putting roughly 10,000 dollars of spend per year on the Sun Country card. Plus status adds perks such as advanced seat selection discounts and other small comforts that matter on bare bones fares.
The Frontier Airlines World Mastercard offers a similar structure but with slightly more appealing category bonuses for budget urban travelers. Restaurant dining typically earns 3 miles per dollar, which equates to roughly 3 percent back in Frontier flights, while everyday purchases sit at 1 mile per dollar. If you eat out frequently or use delivery apps, that 3X rate can make a meaningful difference over a year. Some offers also let heavy spenders qualify for or maintain Frontier elite status based on a combination of flights and credit card spending, which can unlock further savings on seat assignments, bags for companions, and free last-row stretch seating on certain tiers.
Both cards sit on payment networks that bring generic travel benefits as well. As a Visa Signature product, the Sun Country card can come bundled with benefits like rental car collision damage waiver, lost luggage reimbursement and travel accident insurance when trips are booked with the card. Travelers renting cars in Phoenix or Miami, for example, might be able to decline the rental agency’s collision damage waiver and rely on the Visa benefit instead, saving around 20 to 30 dollars per day. The Frontier Airlines World Mastercard, being a World Mastercard, may include its own suite of travel protections and purchase benefits, though those are more modestly advertised. For both products, you should confirm exactly which protections apply on your specific account and use them as a modest safety net, not as the core reason to choose the card.
Real-World Savings Scenarios for Budget Flyers
To figure out which card is better for you, it helps to walk through concrete examples and tally the savings. Let us look at three common budget traveler profiles: the solo light packer, the family vacationer and the side hustle commuter.
First, consider a solo traveler based in Denver who flies Frontier six times a year to visit friends in Dallas and San Diego, usually with one large checked bag. Without any card, this traveler might pay around 40 dollars each way for that bag when buying online in advance. Over six round trips, that is roughly 480 dollars in bag fees alone. If they hold the Frontier Airlines World Mastercard and qualify for the two free checked bags benefit on each trip, those six journeys could incur zero bag fees. They also earn 5X miles per dollar on tickets, so a 120 dollar average fare produces 600 miles per segment, or 7,200 miles per year just from base fares. The combination easily overwhelms the annual fee, and the traveler can redeem accumulated miles for at least one extra domestic trip each year.
Next, picture a Minneapolis family of four who flies Sun Country twice a year: once to Las Vegas in winter and once to Orlando in summer. Each traveler checks one bag and the parents occasionally pay for advanced seat selection to keep everyone together. Suppose each round trip costs around 250 dollars per person in base fare and 35 dollars per segment for a checked bag booked in advance, for a total of 560 dollars in bag fees across the two trips. With the Sun Country Visa Signature’s bag discount applied to all four travelers on the same reservation, that bag bill might shrink to around 280 to 350 dollars depending on the exact discount level. Add in points earned at up to 5X on the 2,000 dollars in airfare and ancillary purchases, and the family could see around 10,000 points, enough to knock a significant chunk off a future trip. For this family, the Sun Country card looks attractive because the perks spread across multiple travelers.
Finally, imagine a Phoenix based part time remote worker who takes advantage of off-peak Sun Country and Frontier fares to spend chunks of the year working from different cities. One month they head to Minneapolis on Sun Country, another month they hop to Orlando on Frontier. They rarely check bags, preferring a single carry-on, but they value flexibility in last minute bookings and are comfortable mixing and matching carriers. In this case, neither card perfectly fits every trip, because each set of perks is tied to its airline. This traveler might be better served by a general travel rewards card with transferable points and no bag benefit, using Sun Country or Frontier only when the cash fare is clearly cheapest. The airline cards shine most for travelers willing to commit to a single carrier for a majority of their budget flights.
The Takeaway
Both the Sun Country Visa Signature and the Frontier Airlines World Mastercard can be smart tools for budget flyers, but they are far from universal recommendations. Each one is sharply tuned to its airline’s particular fee structure and route map, and both carry annual fees that require at least a few trips a year to justify.
You are a strong candidate for the Sun Country Visa Signature if you live near Minneapolis Saint Paul or another Sun Country focus city, travel with family or friends on the same reservation, and often need checked bags. The baggage discounts that can apply to multiple companions, the path to Plus status through card spending and the ability to keep Sun Country Rewards points from expiring all tilt the math in your favor, especially if Sun Country is your default choice for winter and spring break escapes.
The Frontier Airlines World Mastercard tilts toward travelers who fly Frontier multiple times a year with checked luggage and value a big initial infusion of miles. Its two free checked bags for the primary cardholder, priority boarding on Frontier operated flights and award redemption fee waivers can easily save several hundred dollars annually for a Denver, Orlando or Las Vegas based flyer. Add in strong earning on Frontier purchases and a restaurant bonus category, and it becomes an efficient machine for turning everyday spending into budget flights.
If you live in a city served well by both airlines, the decision comes down to loyalty and luggage. Choose Sun Country’s card if your trips are mostly from Minneapolis with family in tow; choose Frontier’s card if you are a solo or couple traveler hopping frequently on Frontier’s domestic web and checking bags almost every time. If neither airline accounts for at least three or four trips a year for you, a flexible general travel rewards card is likely the safer, simpler choice.
FAQ
Q1. Which card is better overall for budget travelers, Sun Country Visa Signature or Frontier Airlines World Mastercard?
The better card depends on where you live and how you travel. If you are based near Minneapolis and frequently fly Sun Country with family or companions, the Sun Country Visa Signature is often stronger because its baggage savings can apply to multiple people on the same reservation. If you fly Frontier several times a year from cities like Denver, Orlando or Las Vegas and usually check at least one bag yourself, the Frontier Airlines World Mastercard’s two free checked bags and richer welcome bonuses can produce greater net savings.
Q2. How many trips per year do I need to make these cards worthwhile?
As a rough guideline, if you check a bag on at least two or three round trips a year with the same airline, the value of free or discounted baggage alone can outweigh an annual fee around 89 dollars. A Denver based traveler making four Frontier round trips with checked bags will usually come out well ahead with the Frontier card. A Minneapolis family flying Sun Country twice a year with several checked bags on the same reservation can see similar benefits from the Sun Country card.
Q3. Do the baggage benefits cover my travel companions or just me?
In many cases, Sun Country Visa Signature baggage discounts can apply to companions on the same reservation when the primary cardholder pays for the flights, which is especially helpful for families. Frontier’s strongest baggage perk is focused on the primary cardholder, who can receive two free checked bags on eligible flights. Companion coverage on Frontier is more dependent on elite status and specific promotions, so it is less consistent for casual travelers.
Q4. Can I use these cards internationally without extra fees?
Both cards are designed primarily for United States based travelers flying North American and near international routes. You should check the most recent terms for each card regarding foreign transaction fees. Some co-branded airline cards waive these fees, while others charge a small percentage on purchases made outside the United States. If you expect to use your card frequently abroad, a general travel credit card with no foreign transaction fees may be a better everyday option.
Q5. Are the travel protections on these cards strong enough to skip separate insurance?
Both products come with some travel protections, such as rental car collision coverage and lost luggage reimbursement on qualifying bookings. These benefits can be very helpful for routine trips, such as renting a car for a weekend in Las Vegas. However, they are not a substitute for comprehensive travel insurance if you are concerned about major trip interruption, medical evacuation or very expensive itineraries. Review your card’s guide to benefits carefully and consider a separate travel policy for complex or high-cost trips.
Q6. What if I sometimes fly both Sun Country and Frontier?
If you split your flying roughly evenly between the two airlines but do not fly either one frequently, holding both cards is rarely necessary. In that case, a flexible rewards card that earns transferable points across many airlines may be more efficient. If you do decide to pick one airline to favor, choose the card aligned with your home airport’s stronger schedule and your typical luggage pattern. For instance, if most of your bag-heavy trips are on Frontier from Denver, the Frontier card will usually beat the Sun Country card even if you occasionally fly Sun Country without bags.
Q7. How do welcome bonuses on these cards impact the decision?
Welcome bonuses can dramatically boost first year value. Frontier’s current offers often include 50,000 or more miles after first purchase or a low spend threshold, which can cover multiple domestic economy trips at off-peak times. Sun Country’s bonuses tend to be more modest but can still offset at least one round trip flight. If you know you have big expenses coming, such as moving costs or a home improvement project, timing your application to meet the minimum spend for a strong bonus can tilt the decision in favor of whichever airline you expect to use most in the next 12 months.
Q8. Are either of these cards good for everyday non-travel spending?
Both cards earn rewards on everyday purchases, but their value is tightly tied to their specific airlines. Frontier’s 3X miles on restaurants can be reasonable for people who dine out frequently, but many general travel cards or cash back cards still offer stronger returns and more flexibility. Sun Country’s non-airline earning rates are modest, so the card is best used primarily for flights and airline-related spending. If you want a single card for groceries, gas and travel, you may be better off with a general rewards card and then paying cash for budget airline tickets when they are cheapest.
Q9. Do these cards help me reach elite status faster?
Yes, to a degree. Sun Country allows members to earn Plus status via either flight segments or qualifying spend on the Sun Country Visa Signature card, giving infrequent but higher-spend travelers a path to extra perks such as preferred seat discounts. Frontier has periodically tied elite qualification to a mix of flights and spending on the Frontier Airlines World Mastercard. In both cases, if you are close to qualifying for status and can responsibly shift some spending onto the card, the elite shortcuts can be useful. They should be seen as a bonus, not a primary reason to carry the card.
Q10. If I cancel the card, what happens to my airline miles or points?
In most cases, the miles or points you have already earned remain in your airline loyalty account even if you close the credit card, but you may lose any special protections like extended expiration or boosted earning rates. For Sun Country, the card can help keep your Rewards points from expiring as long as the account remains open and active, so canceling may start the standard expiration clock again if you are not flying regularly. With Frontier, miles follow the program’s usual expiration rules, which typically require some qualifying activity within a set period. Before canceling, check your current balance and consider redeeming for flights or extras if you are unlikely to fly that airline again soon.
