Vietnam–South Korea Flights Surge Despite Higher Fares

Vietnam–South Korea air travel is entering one of its busiest blossom seasons on record in early 2026, as new routes and looser visa rules accelerate demand faster than airlines can raise fares.

Record Two-Way Demand in Early 2026

Publicly available tourism data show that Vietnam and South Korea have become two of Asia’s most closely linked travel markets, with each ranking among the other’s top sources of international visitors. Regional travel industry reports for the first quarter of 2026 indicate that approximately 167,000 Vietnamese travelers visited South Korea in the period, a year-on-year increase of close to 30 percent, driven largely by cherry blossom trips to Seoul, Busan and Jeju.

Vietnam’s inbound figures tell a similar story from the opposite direction. According to recent Vietnamese tourism statistics summaries, South Korea remains one of Vietnam’s largest source markets in early 2026, alongside China and Japan, helping push monthly foreign arrivals into the multi-million range. Beach destinations such as Da Nang, Nha Trang and Phu Quoc, along with golf and family resorts, are popular with Korean travelers seeking warm-weather escapes before and after the blossom peak in their own country.

Industry analyses of the wider Asia travel recovery note that both countries are benefiting from a broader rebound in regional mobility and entertainment-led tourism. The popularity of Korean pop culture among Vietnamese travelers, and the rising profile of Vietnamese coastal destinations among South Koreans, are reinforcing a loop of demand that is now particularly visible during the March and April blossom window.

New Routes and Higher Fares on Key City Pairs

Air connectivity between Vietnam and South Korea has expanded rapidly ahead of the 2026 blossom season. Aviation briefings and airline announcements describe new and reinstated routes linking secondary Vietnamese cities to Korean hubs, including recent launches connecting Nha Trang and Phu Quoc directly with Seoul and Busan. National and private carriers from both countries are deploying additional capacity on trunk routes such as Hanoi–Seoul and Ho Chi Minh City–Seoul while also growing flights to regional airports.

Despite this growth, average fares on many Vietnam–South Korea routes have risen for peak blossom dates, according to online fare tracking across major booking platforms. Strong leisure demand, limited takeoff and landing slots at key Korean airports and a concentration of travel in late March and early April have combined to push up ticket prices. Travel portals show that non-stop economy tickets during the core bloom period often price substantially higher than departures in February or late April, particularly on weekend departures.

Analysts following the regional aviation sector suggest that airlines are using the blossom season to rebuild yields after several years of discounted recovery fares. Capacity increases have mostly kept up with structural demand, but not with the short, intense surge associated with flower festivals, meaning that late bookers are facing especially steep prices on popular dates and times.

Visa Easing and Entry Systems Shape 2026 Travel

Policy changes are also reshaping the Vietnam–South Korea travel corridor in 2026. South Korea has announced a tourism strategy that includes easing visa requirements for 11 countries, with Vietnam among the key beneficiaries. Publicly available information on the plan outlines five-year multiple-entry visas for travelers from China and Southeast Asia who have prior visit records, and a proposed 10-year multiple-entry option for residents of major cities in China and Vietnam.

In parallel, South Korea is expanding use of automated immigration gates and encouraging more international flights to regional airports beyond the Seoul metropolitan area. The objective, according to government statements reported in Korean and regional media, is to disperse inbound demand and reduce congestion at main hubs during peak seasons such as cherry blossom. For Vietnamese travelers, this may translate into faster processing and more non-stop options to cities like Busan and Daegu.

Vietnam, for its part, has been pursuing broader visa liberalization and digitalization since 2024 and 2025, including longer visa-free stays for select nationalities and wider application of electronic visas. While South Korean citizens already enjoy relatively straightforward entry procedures, continued improvements to e-visa systems and automated border controls are expected to further smooth travel for Korean tourists heading to Vietnamese beach and cultural destinations throughout 2026.

Blossom Festivals Drive Itineraries on Both Sides

Cherry blossom and spring flower festivals are at the center of current travel patterns on the corridor. Tourism promotion campaigns by Korean destination marketing bodies highlight events such as the Jinhae Gunhangje Cherry Blossom Festival in Gyeongsangnam-do, the Yeongdeungpo Yeouido Spring Flower Festival in Seoul, and cherry blossom viewing on Jeju Island. These campaigns are widely publicized in Vietnam, contributing to the surge of Vietnamese group and independent travelers timing their trips to coincide with full bloom.

Conversely, South Korean visitors to Vietnam are using blossom season at home as a bookend for regional travel, pairing early or late-bloom trips in Korea with off-peak stays in Vietnam. Coastal areas like Da Nang, Nha Trang and Phu Quoc, along with cultural centers such as Hoi An and Hue, feature prominently in Korean-language tour packages advertised for spring 2026. Warmer weather, beach activities and golf are positioned as complements to the cooler, festival-focused itineraries in Korea.

Travel behavior studies for the region suggest that social media sharing of blossom images is amplifying demand. Viral content from previous years’ cherry seasons in Seoul and Busan continues to influence Vietnamese travelers’ destination choices, while drone footage and resort imagery from Vietnam’s islands capture the attention of Korean holidaymakers planning multi-stop spring trips.

Practical Advice for International Travelers Using the Corridor

For visitors from outside the two countries who plan to use Vietnam and South Korea as part of wider Asia itineraries, current conditions on the corridor point to several practical considerations. First, booking long-haul connections and regional segments well in advance is becoming increasingly important around late-March and early-April blossom peaks. Monitoring fares several months ahead can help secure more competitive prices on non-stop services between major Vietnamese cities and Seoul or Busan.

Second, travelers are advised by many booking platforms and travel advisories to remain flexible with travel dates and airports. Shifting itineraries by a few days on either side of core festival dates, or flying into alternative airports where options exist, can materially reduce costs. Choosing early-morning or late-night departures from Hanoi and Ho Chi Minh City, and considering midweek travel, may also help avoid the sharpest price spikes.

Third, visitors should review the latest visa rules separately for both countries and not assume reciprocity. While South Korea’s planned multiple-entry visas and Vietnam’s expanded e-visa and visa-waiver measures are making travel easier for many nationalities, eligibility criteria, documentation requirements and permitted lengths of stay vary. International tourists are encouraged by official consular guidance to check current regulations close to departure and ensure passport validity and onward travel documentation meet airline and border control expectations.

Finally, given the rapid growth in two-way tourism and the concentration of travel in blossom season, accommodation in popular districts can sell out well in advance. Industry reports note particularly strong demand around Seoul’s riverside parks, Busan’s waterfront areas and Vietnam’s major beach zones. Early hotel bookings, combined with realistic transit times between airports and city centers, can help travelers make the most of a corridor that is becoming one of Asia’s busiest spring travel links.
