56×45×25 cm; L+W+D ≤ 115 cm

22×17.7×9.8 in; L+W+D ≤ 45.3 in

Weight limit: 7 kg (15.4 lb)

Current table: one 7 kg bag in every listed class, 56×45×25 cm including wheels/handles. The same page also says 115 cm total, which conflicts with the 126 cm box sum. This checker conservatively applies BOTH; confirm a bag above 115 cm with THAI. A conditional additional piece for Star Alliance Gold in First/Silk on a journey involving two or more Star Alliance carriers needs manual confirmation; ordinary premium class alone gives no extra piece.

Measure the full external bag size, including wheels and handles.

Baggage fees

No reliable fixed price is listed here. Check your booking for the cost of adding a bag; an unlisted price does not mean it is free.

Official baggage policy
How to use this policy

Check cabin bag dimensions, weight and personal-item limits separately. A bag has to pass every published limit at once; being under the length and width limit does not help if the depth, weight, or fare-specific allowance is tighter.

Editorial signal only. Measure the packed bag and verify the operating carrier's rule.

Thai Airways liquids policy

THAI publishes containers up to100 ml in one transparent resealable1 L bag; medical, infant-food and dietary exceptions apply. Sealed duty-free purchases need proof where requested. Check departure/transit security requirements.

Family & Infants

Infant (under 2)

Confirm the infant ticket and issuance/travel-date baggage regime. The current piece table gives one checked infant piece at23 or32 kg according to cabin; this is not an extra ordinary cabin bag.

Stroller

The reviewed Spanish-market checked page allows one own-use foldable stroller, car seat or wheelchair free, not one of each. Confirm gate collection and destination delivery with THAI.

Car seat

For cabin use, the infant assistance page requires an approved car seat and a paid child seat. Aircraft restrictions must be confirmed; no automatic cabin acceptance.
