If you have flown T’way Air, note the new name.
Since September 10, T’way Air has been operating as Trinity Airways.

The old T’way website now redirects to Trinity Airways.
And right after the rebrand, the airline announced new daily flights from Seoul Incheon to Nagoya and to Kobe from December 18.

What changed and what did not

Item Details
New name Trinity Airways
From September 10, 2026, on all domestic and international flights
Airline code and flight numbers Still TW
Tickets bought as T’way Valid as they are, nothing to change
Schedules and fare rules Unchanged
What is new Website and app, airport counter signs, uniforms

The key point: if you already booked with T’way, you do not need to do anything.
Flight numbers stay TW and your booking terms are the same (Newspim and other Korean reports).

At the airport, look for Trinity Airways signs rather than T’way.

Trinity Airways belongs to the Sono Trinity Group and plans to add A330-900neo and B737-8 aircraft this year.

Seoul Incheon–Nagoya (daily from December 18)

Route Departs Arrives
Incheon → Nagoya (Chubu) 08:00 09:55
Nagoya (Chubu) → Incheon 10:55 13:05

Per Travel Daily and other Korean reports. Bookings opened on September 18.

An 08:00 departure lands before 10am, so the first day is almost a full day.
The catch is an early start to Incheon, especially from outside Seoul.

Nagoya is known for Nagoya Castle, Atsuta Shrine and food like hitsumabushi (grilled eel on rice) and tebasaki (chicken wings).
It is also a common base for Takayama and Shirakawa-go, so a December start suits winter trips to see the villages in snow.

Seoul Incheon–Kobe (daily from December 18)

Route Departs Arrives
Incheon → Kobe 14:10 15:55
Kobe → Incheon 16:55 18:55

Per Aju Business Daily and other Korean reports.

Kobe Airport sits on an artificial island, with the Port Liner taking you into central Kobe (Sannomiya) quickly.
It gives travellers another way into the Kansai region besides Kansai International.
With a 14:10 departure, count the first day as half a day.
