Quick summary
T’way Air’s promotional Europe–Seoul fares ended on March 28, 2026, and were projected to rise 20–30% afterwards, cutting its edge over Korean Air and Asiana to roughly 15–25%. Our fare scan on October 8, 2026 found London–Seoul Incheon round-trip economy from €501, departing November 15 with one stop.
Economy still includes two meals and 23kg of checked baggage, but online seat selection costs €30. The rebrand to Trinity Airways, announced August 6, 2026, brings lounges, Wi-Fi and seatback screens gradually from the second half of 2026.
T’way’s promotional Europe–Seoul fares were confirmed only through March 28, 2026. Fares were projected to rise 20–30% after that, narrowing its gap with Korean Air and Asiana to roughly 15–25%.
The Korean low-cost carrier is no longer automatically the cheap answer on Europe–Seoul.
For travelers departing Europe, the decision turns on what the remaining discount covers once seat selection and baggage are added. The name is changing, too: T’way Air is becoming Trinity Airways.
T’way becomes Trinity Airways: what changes now
T’way Air announced the rebrand on August 6, 2026, positioning itself as a “selective service carrier” that mixes short-haul and long-haul premium offerings, according to The Straits Times. The rollout begins in the second half of 2026. Premium lounges, inflight entertainment, onboard Wi-Fi and upgraded meals will arrive gradually as flights operate under the new name, according to The Straits Times. The airline also plans a loyalty programme linked to Sono Trinity Group’s hotels and resorts, bringing flights and accommodation into one platform.
The expansion reaches beyond Europe. T’way will lift Sydney–Seoul service to daily flights from October 2026, a move announced on July 23, 2026 and reported by BriefGlance. A partnership with the Korea Tourism Organization supports the move; the organization is targeting more than 300,000 Australian visitors in 2026 after a 23% rise in 2024.
Fleet plans come with a caveat. The roadmap includes Airbus A330-900neos and leased Boeing 777-300ERs, but the rebrand still needs final foreign regulatory approvals, so the timeline can move. What you get on board therefore depends on when you fly, not just the name on your booking.

What T’way economy includes on Europe–Seoul
Economy fares on T’way’s Europe–Seoul routes include two meals and 23kg of checked baggage as standard, according to T’way’s own Europe–Seoul fare announcement. On a long-haul sector, that matters: a legacy carrier’s headline price already assumes a bag and a meal, while a stripped low-cost fare does not.
The main extra is the seat. A couple pre-booking adjacent seats adds €60 to the trip. That is a small sum against a long-haul fare. It still belongs in a like-for-like comparison.
The upgraded meals will reach long-haul routes first, then medium-haul destinations such as Jakarta and Singapore, according to The Straits Times. Europe–Seoul is in that first wave, making catering the part of the rebrand a 2026 Europe–Seoul passenger is most likely to notice.
Current London–Seoul fare reality check
Our fare scan on October 8, 2026 covered London–Seoul Incheon round-trip economy. The lowest fare departed November 15 and returned November 23, with one stop; the dearest departed December 19.
Dates drove the spread.
Mid-November and late-October departures produced the cheapest fares (€501, €540, €550). December dates filled the top of the range (€855, €897, €1,067). Within October, the scan found both €540 and €901. Moving a trip by a few days can matter more than moving it by a season.
Stops did not decide the price either. The scan’s only nonstop, departing December 24, cost €897, more than several one-stop fares on cheaper dates. T’way’s European network serves Frankfurt, Rome, Paris CDG, Barcelona and Zagreb, according to the airline’s European route announcement. Travelers willing to connect or change their departure point have alternatives worth pricing: routing through Beijing or Shanghai on Chinese carriers, or departing from Warsaw rather than a western hub.
Seoul Incheon as a hub: the schedule
A Europe–Seoul fare is rarely only about Seoul, given Seoul Incheon’s reach. As of a July 2, 2026 update, 163 airports worldwide had direct flights to ICN, covering 155 cities in 50 countries. The airport had 87 airlines operating into it, with Korean Air connecting the most airports, 91.
ICN recorded 16,375 arriving flights in the month of that update, about 546 a day. Osaka and Tokyo were the busiest inbound markets, together accounting for 2,196 arrivals. That was roughly 13% of the monthly total.
For a traveler continuing past Korea, this breadth has practical value. Onward options do not depend on one airline’s network.
Comfort and fleet caveats before you book
The fleet you board in 2026 is not new. T’way’s A330-200s averaged 13.6 years old at the time of a June 2024 review of a Jeju–Seoul flight. A 14-hour Seoul–Rome business-class flight in April 2025 had no in-flight entertainment at all: no screen, no map, no audio.
In 2025, the airline added two Boeing 777s that had previously flown for Cathay Pacific. One carries a first-class cabin and operates the Seoul–Barcelona route. It is a different product from the A330-200s, so the aircraft assigned to your route matters as much as the fare.
A booking made now may still fly an older cabin after the brand has changed.
What the narrower gap means for your booking
Price your exact dates on both carriers before you commit. The departure date was the biggest single variable in the fares our scan surfaced.
Travelers with flexible dates. The cheapest round-trip was €501, against €1,067 for the dearest. That €566-per-person spread is the largest lever in the comparison, and it is worth checking the same route across a two-week window before choosing an airline. Less suited: anyone locked to late-December school holidays, where the scan’s top fares cluster.
Travelers who need a specific seat. Online seat selection costs €30 per person on these routes, the only add-on most economy passengers will meet. Budget it per traveler, not per booking. Less suited: travelers who do not care where they sit, for whom the fare you see is the fare you pay.
Travelers who want a newer cabin. Fleet renewal is uneven, and passengers who care about the onboard product should check the scheduled aircraft before paying. Less suited: anyone flying before the second-half-2026 rollout reaches their route, who should expect the older cabin.

Questions? Answers.
Does T’way include checked baggage on all Europe–Seoul economy fares?
Yes. Economy fares on the European routes include 23kg of checked baggage and two meals as standard, according to the airline’s own fare announcement. Online seat selection is the main extra, at €30.
How does T’way seat comfort compare to Korean Air on long-haul flights?
T’way flies widebodies, but the cabins vary by aircraft. Its A330-200s averaged 13.6 years old in mid-2024, and a 14-hour Seoul–Rome business-class flight in April 2025 had no in-flight entertainment. The rebrand’s screens and Wi-Fi arrive gradually from the second half of 2026, so comfort depends on which aircraft is scheduled.
Can I connect onward from Seoul to other Asian cities?
Seoul Incheon is served by 87 airlines connecting 163 airports in 50 countries, as of July 2, 2026, so onward options are broad. Whether a single ticket covers the whole journey depends on the fare you buy.
What happened to T’way’s promotional fares after March 2026?
The promotional structure was confirmed only through March 28, 2026, and fares were projected to rise 20–30% afterwards, narrowing T’way’s gap with Korean Air and Asiana to roughly 15–25%. Our October 8, 2026 scan found London–Seoul round-trip economy from €501.
