No accessibility-specific email address or text/TTY relay is published; every request is routed through the Booking Center.

Powered wheelchairs & batteries

The part that goes wrong. Battery chemistry and watt-hours decide whether your chair flies, and the rules differ depending on whether the battery can be removed.

Powered chairs accepted
Conditional

Accepted in checked baggage only, and "approval by an airline in advance is essential". The Korean assistance page requires you to contact the reservation centre at least 48 hours before departure; a battery-powered wheelchair may not be taken into the cabin.

Conditional

Lithium-battery electric wheelchairs are carried in checked baggage only, with prior airline approval and short-circuit protection. If the battery can be detached the chair body goes in the hold and the battery must be carried in the cabin.

Watt-hour cap — battery stays in the chair
Not published

Not published — for a non-detachable battery T'way requires prior approval, short-circuit prevention and a secured chair, but states no watt-hour cap.

Watt-hour cap — battery removed into the cabin
Not published

Not published — a detachable drive battery must travel in the cabin (checked carriage prohibited) but T'way sets no watt-hour ceiling for it; the 300 Wh figure it publishes is for spare batteries.

Watt-hour cap — spare battery
300 Wh

Spare battery, carry-on only: "1 battery within 300 Wh or 2 batteries which not exceed 160Wh". Spares are prohibited in checked baggage.

"1 battery within 300 Wh or 2 batteries which not exceed 160Wh" may be carried in the cabin — so one spare at up to 300 Wh, or a maximum of two if each is 160 Wh or less.

Not published

Not published — T'way says nothing about accessible lavatories on any of its aircraft.

Crew help you transfer

"We operate priority seat services for pregnant passengers with difficulty in moving, pregnant passengers, and infants (less than 24 months old)."

Fleet detail. T'way publishes cargo-compartment door heights: A330-300/200 and B777-300ER 66 in (167.64 cm); B737-800 / B737-8 48 × 35 in (88.9 cm). It then caps the wheelchair height it will accept at 80 cm, allowing for loading tolerance, work safety and damage prevention.

Worth knowing

The airline still trades as T'way Air: its Customer Center says "T'way Air is beginning a new chapter as 'Trinity Airways'" and that operations under the new name start only once domestic and international approvals are complete, the date to be announced separately — so every page still reads 'T'way Air'. CONTRADICTIONS A HUMAN SHOULD RE-CHECK: (1) the Korean assistance page states the 48-hour prior-approval deadline for powered wheelchairs explicitly, the current English translation of the same page does not — the 48 h figure here comes from the Korean text; (2) the free-baggage page says "Wheelchair with a separated battery. However the battery should be safely packed ... and it should be transported as a checked baggage", while the dangerous-goods page says a detached battery must go in the cabin and is prohibited in checked baggage — the dangerous-goods page is the one that governs; (3) the restricted-items table lists "wheelchair" among cabin-permitted walking aids, contradicting the assistance page's gate-collection procedure. T'way serves Guam (its restricted-items page describes a Daegu–Guam routing via Osaka), so US DOT rules apply, but no Complaint Resolution Official or US disability-assistance page was found. The full-size www.twayair.com content pages render only via JavaScript; the m.twayair.com mobile equivalents (contents/69, /150, /148, /151) serve the same text as plain HTML and were used instead.
