The British Airways American Express Premium Plus Card is one of the most powerful tools in a UK traveler’s wallet, largely thanks to its Companion Voucher and boosted Avios earning. Yet a surprising number of cardholders use it in ways that deliver poor value: burning the voucher on economy hops to Europe, sliding the Avios slider to the wrong place, or redeeming for low-value extras instead of flights. If you want genuinely outsized trips for your points, you need to stop treating your Premium Plus Card like an ordinary cashback card and start thinking strategically.

What Makes the Premium Plus Card Different
The British Airways American Express Premium Plus Card is built for people who intend to redeem Avios for flights, not for casual cashback-style spending. Cardholders earn an elevated rate of Avios on purchases and, crucially, receive a Companion Voucher after spending £15,000 in a card year. That voucher can be used on British Airways, Iberia or Aer Lingus reward flights and, unlike the voucher on the free BA Amex, it is valid in all cabins, including premium economy, business and first, with a two-year validity window.
In practice, that means a couple in London could book two Club World business class seats to New York using Avios for one ticket and the Companion Voucher for the second, paying only the Avios for a single passenger plus taxes and fees for both. Solo travelers can instead use the voucher for a 50 percent Avios discount on a single reward seat, again in any cabin. This flexibility, combined with enhanced reward seat availability in Club World on some routes, is the core reason the Premium Plus Card commands a sizeable annual fee.
Because of that power, almost every decision you make around the card should be evaluated through the lens of “Avios per pound of value.” Used well, a single Companion Voucher tied to premium cabin long haul can unlock several thousand pounds of flight value. Used poorly, it can barely save a couple of hundred pounds on trips you could have paid cash for.
Stop Burning Your Companion Voucher on Economy Europe Hops
One of the most common missteps is redeeming the Premium Plus Companion Voucher on short-haul economy flights from the UK to Europe. At first glance, it feels satisfying to “get a free ticket” to somewhere like Barcelona or Rome. In reality, the combination of modest cash fares and high taxes and fees often makes this one of the poorest ways to use the voucher.
Consider a typical off-peak return from London Heathrow to Barcelona in economy. Cash fares in sale periods can sit around £80 to £120 per person including taxes. A reward ticket on British Airways might cost, for example, 10,000 to 18,000 Avios plus roughly £35 to £50 in taxes and fees per person, depending on which Avios-plus-cash combination you choose. Using a Companion Voucher to cover one of those tickets saves you at most those 10,000 to 18,000 Avios and maybe under £100 of cash. You have “spent” your entire annual voucher on a saving that sometimes barely outperforms simply buying the ticket outright in a sale.
Contrast that with a peak-season Club World redemption from London to New York. After recent Avios pricing changes, a return business-class reward may require in the region of 160,000 Avios plus several hundred pounds per person in surcharges, depending on date and Avios-versus-cash mix. Using your Companion Voucher here can save you around 160,000 Avios on the second ticket or halve the Avios on a solo booking, translating into potential value well into four figures if comparable cash fares are running at £2,000 to £3,000 per person in busy periods. The same voucher that barely moved the needle on a short hop can be transformative on a long-haul premium cabin.
If you mainly travel to European cities, it is generally better to pay cash for sale fares, use Avios for especially expensive last-minute trips, or look at short-haul partner redemptions. Save the Premium Plus Companion Voucher for a big, aspirational long-haul flight in premium economy or higher, where both the cash prices and Avios requirements are materially larger.
Stop Redeeming Avios for Non-flight Extras and Poor-value Options
Another leak in value comes from treating Avios like store points to be redeemed on almost anything: hotels, car hire, wine, or even part-payment discounts off cash tickets where the value per Avios is weak. These options exist for flexibility, but they rarely, if ever, match the value of using Avios plus a Companion Voucher for flights.
For example, you might see an offer to use 20,000 Avios for £120 off a cash fare or hotel booking. That values your points at about 0.6p per Avios. In contrast, a long-haul business class redemption where a pair of tickets might cost £4,000 in cash but consume, say, 160,000 Avios with a Companion Voucher could effectively be giving you well north of 2p per Avios in value, even after factoring in taxes and fees. The difference in outcome over a couple of years can amount to thousands of pounds’ worth of travel.
Similarly, some cardholders routinely slide the “use Avios to pay” control on cash tickets to wipe out modest sums, like using 3,000 Avios to knock £20 off a fare. That might feel satisfying in the moment, but if you later find yourself short of Avios for a premium reward flight, you will have traded away high-value redemptions for trivial incremental discounts.
If your travel plans are unpredictable or you are worried about Avios devaluations over time, it can still make sense to redeem for flights you will actually take in the next 12 to 24 months. The key is to prioritize redemptions where the notional “pence per Avios” is close to or above 1p, which generally means flights, not ground products.
Stop Ignoring Peak vs Off-peak Pricing and Reward Seat Availability
British Airways runs a peak and off-peak pricing calendar for Avios redemptions, and peak dates can cost around 30 to 50 percent more Avios than off-peak on popular routes. If you do not pay attention to this, you can end up wasting both Avios and your Companion Voucher on dates where you are getting less value per point, simply because you booked the first dates you found.
Take London to Dubai in Club World as an example. On some off-peak dates, a return business-class reward might price significantly lower in Avios than during school holidays or major events, sometimes reducing the Avios cost by tens of thousands for the same cabin and route. When you overlay a Companion Voucher, that difference is magnified: halving a smaller off-peak Avios total can free up enough additional Avios for another substantial trip, such as a transatlantic premium economy flight.
Availability is just as important. Each British Airways flight has a limited number of reward seats that can be booked with Avios, even with a Companion Voucher. Premium Plus vouchers do unlock enhanced Club World availability on some routes, but you still need to be flexible. Travelers who always insist on a specific weekend in August to a single destination will find far fewer options than those who can depart midweek, travel outside school holidays, or consider alternative starting airports such as Madrid or Dublin to reduce both taxes and Avios costs.
In practical terms, this might mean deciding that your big annual trip will happen in late September instead of early August, allowing you to book two off-peak premium economy or business rewards to the United States or Asia rather than being shut out or forced into economy at peak pricing. That simple shift can mean your Companion Voucher saves you a far larger chunk of Avios, particularly if you are a family planning trips around half-term or summer holidays where cash fares are highest.
Stop Booking From the UK Only and Overpaying in Surcharges
British Airways Avios redemptions to and from the UK attract high taxes and carrier-imposed fees, particularly on long-haul flights departing London. Cardholders often assume they must start in the UK, then wonder why their “free” flights still cost hundreds of pounds each in surcharges. For Premium Plus Companion Voucher holders, failing to look beyond London can drastically undermine the value they receive.
One real-world strategy used by experienced Avios collectors is to position to a European city with lower departure charges before starting a long-haul reward. For instance, starting a Club World trip from Madrid to New York, rather than London to New York, can significantly reduce taxes and fees per person while often requiring a similar Avios amount for the long-haul segment. The savings can run into several hundred pounds for a couple traveling together, even after paying separately to reach Madrid using a low-cost cash ticket or short-haul Avios booking.
Since Companion Vouchers earned from September 2021 onwards can be used on itineraries starting outside the UK, Premium Plus cardholders should at least price out these alternatives. A traveler based in Manchester or Edinburgh might find that connecting via Dublin, Amsterdam or Madrid on separate tickets yields both lower surcharges and easier reward availability in premium cabins, especially on Iberia-operated flights where Avios pricing can be more favorable.
This approach is not right for everyone, especially families with lots of luggage or tight school holiday windows, but the principle stands: if you always default to starting your reward trip from Heathrow or Gatwick purely out of habit, you may be pouring a large chunk of your Companion Voucher value into taxes instead of flights.
Stop Forgetting How Powerful the Solo 50 Percent Discount Can Be
Many travelers still think of the Companion Voucher as a “2-for-1” tool only for couples or families. Since the rules were updated, Premium Plus cardholders can now use the voucher as a 50 percent Avios discount on a solo booking. Ignoring this option is another way cardholders undersell the card’s potential, especially frequent solo travelers or those whose partners are not as keen on long-haul trips.
Imagine you are traveling alone from London to Tokyo in Club World, a route where cash business-class fares can easily exceed £2,000 to £3,000 in busy seasons. A standard off-peak Club World reward might run to a six-figure Avios amount plus taxes. Using your Premium Plus Companion Voucher as a solo traveler effectively halves the Avios cost. If you instead “save” the voucher in the hope of finding dates that work for two people but end up not using it before expiry, you will have walked away from a huge saving on a trip you were always going to take.
This is especially important for people who travel frequently for work or to visit family overseas. A solo Premium Plus cardholder flying regularly to New York or the Middle East can use the voucher to soften the Avios hit of one premium cabin trip per year. If they were instead to apply that voucher to a last-minute European economy hop with a partner, the relative saving in both cash and Avios would be modest.
When you earn a Companion Voucher, think about your calendar proactively. If you know you will have at least one premium long-haul journey in the next two years, block it mentally as “voucher territory” and plan around that, whether you are traveling alone or with someone else.
Stop Assuming Upgrades With Avios Are Always Better Than Straight Redemptions
The Premium Plus Companion Voucher sits within a wider toolkit of ways to use Avios, including upgrading paid tickets to a higher cabin. While upgrading, for example, from premium economy to business using Avios can represent solid value in some cases, it is not automatically superior to straight reward bookings, particularly once you factor in fare rules and the cost of the underlying cash ticket.
Consider a scenario where a return premium economy cash fare from London to Los Angeles costs around £1,000, and a business-class fare costs £2,500. If an upgrade from premium economy to business requires the Avios difference between the two cabins on the reward chart, you might find yourself spending tens of thousands of Avios on top of the £1,000 ticket. Depending on dates and availability, it could be cheaper in Avios terms to book a full Club World reward with a Companion Voucher instead, even though taxes and fees on reward bookings are substantial.
Another complication is that when you use Avios to upgrade a ticket that was originally booked with a Companion Voucher, you do not get any additional “half-price” treatment on the upgrade portion. The voucher has already done its work on the base reward price; the Avios needed to upgrade are based on standard differentials between cabins. Travelers who assume they are stacking multiple benefits may be disappointed when they see how many Avios are still required to move from Club World to First on a long-haul route.
The rule of thumb: price out both options. Compare the total cash plus Avios cost of booking a reward flight with the Companion Voucher against buying a lower cabin cash ticket and upgrading with Avios. Then decide which one gives you the better pence-per-Avios outcome and keep in mind flexibility and fare rules, not just headline numbers.
The Takeaway
The British Airways American Express Premium Plus Card can deliver exceptional value, but it is unforgiving if you use it casually. Redeeming the Companion Voucher on cheap European economy flights, eroding your Avios stash on low-value part-pay-with-Avios redemptions, ignoring off-peak calendars and alternative departure points, or misunderstanding upgrade mechanics are all ways to turn a premium product into a mediocre one.
To get the most from the card, anchor your strategy around one or two significant long-haul trips in premium economy, business or first every couple of years. Earn your Companion Voucher deliberately, wait for dates where off-peak pricing and availability line up in your favor, consider starting outside the UK if surcharges are a concern, and do not be afraid to use the voucher solo if that is how you actually travel.
If you consistently measure the value of each redemption in terms of approximate pence per Avios, the right decisions become clearer. The Premium Plus Card and its Companion Voucher are not just perks; used correctly, they are levers that can turn everyday spending into the kind of travel experiences that would otherwise feel out of reach.
FAQ
Q1. What is the key benefit of the British Airways American Express Premium Plus Companion Voucher?
The Companion Voucher lets you book a reward flight and either take a second person in the same cabin for no extra Avios, or, if you travel solo, get 50 percent off the Avios cost of one seat, in any cabin from economy to first.
Q2. Why is using the Companion Voucher on short-haul economy flights often poor value?
Because cash fares on routes like London to Barcelona or Rome are frequently under £150 return, the Avios and voucher you use replace a relatively small cash outlay. That same voucher could offset hundreds of thousands of Avios on long-haul premium cabins, where cash fares are far higher.
Q3. How can I roughly judge whether a redemption is good value for my Avios?
Divide the cash price you are avoiding by the number of Avios you would spend. If you are getting close to or above 1p per Avios, it is usually solid value; below about 0.6p per Avios is generally weaker, especially for Premium Plus cardholders.
Q4. Is it better to use Avios to reduce the cash price of tickets or to book full reward flights?
Full reward flights, especially in premium cabins with a Companion Voucher, almost always give better value per Avios than using small amounts of Avios to shave £10 or £20 off cash tickets.
Q5. Can I still benefit from the Companion Voucher if I travel alone?
Yes. Solo travelers can use the Premium Plus voucher as a 50 percent Avios discount on one reward seat in any cabin, which can be extremely valuable on long-haul routes in premium economy, business or first.
Q6. How do peak and off-peak dates affect my Companion Voucher strategy?
On peak dates you need more Avios for the same route and cabin, so your per-point value can drop. Whenever possible, aim to use your Companion Voucher on off-peak dates, when the base Avios requirement is lower.
Q7. Why do people suggest starting reward journeys outside the UK?
Departures from London often carry high taxes and carrier charges. Beginning your long-haul reward trip from cities like Madrid or Dublin can reduce those cash costs and may also open up better Avios pricing and availability.
Q8. Can I upgrade a Companion Voucher booking to a higher cabin using Avios?
In many cases you can upgrade if there is reward availability in the higher cabin, but you will pay the normal Avios difference between cabins. The voucher does not discount the Avios cost of the upgrade itself.
Q9. Are there situations where using Avios for non-flight options makes sense?
It can make sense if you have a modest Avios balance you are unlikely to grow, or if you will not be able to travel long haul before your points expire. However, for Premium Plus cardholders who can plan at least one major trip, flights almost always offer better value.
Q10. What is the single most important habit to change for better Avios value with this card?
Stop redeeming impulsively. Before using Avios or your Companion Voucher, compare the cash price you are avoiding, check peak vs off-peak dates, look at alternative departure points, and estimate pence per Avios. A few minutes of analysis can multiply the value you get from the card.
