The maximum Thai Airways carry-on size is 56 x 45 x 25 cm, or 22 x 18 x 10 inches as Thai Airways publishes it. These measurements include wheels, handles, and any external pockets, so a bag marketed as "22 inch" can go over if its wheels push the total past 56 cm. Always measure your bag packed, not empty.

Thai Airways limits carry-on bags to 7 kg (15.4 lb).

Does Thai Airways charge for carry-on bags?

No. Thai Airways includes a free carry-on bag plus a free personal item on every fare, including the Economy Saver fare.

What counts as a personal item on Thai Airways

Allowed

  • Small laptop bag up to approximately 37.5 x 25 x 12.5 cm and 1.5 kg
  • Handbag
  • Duty-free purchases within reason

Common Thai Airways carry-on mistakes

  • Assuming the 7 kg Economy limit is loosely enforced. Thai weighs bags at check-in and gate.
  • Thinking the March 2026 piece-concept change loosened carry-on rules. It primarily affects checked bags, not cabin allowance.
  • Treating a laptop backpack as a personal item when it exceeds the small personal item size.

Thai Airways vs Singapore Airlines carry-on

Thai Airways gives Economy 7 kg in a 56x45x25 cm bag plus one small personal item, which is the same 7 kg weight Singapore Airlines allows Economy. The practical difference is enforcement. Thai may spot-check bags on a scale at check-in and at the gate. In premium cabins Thai keeps the same single 7 kg bag, with an extra piece only for Star Alliance Gold members on multi-Star journeys, so business travelers should not expect a second bag by default. If you fly Economy and pack to exactly 7 kg you are fine on either carrier, but Thai is the stricter of the two on weight.

Effective March 2, 2026 THAI uses the piece concept on journeys involving TC1 (Americas, including US/Canada), on TC2 (Europe/Africa/Middle East) to/from TC3 (Asia/Australia/NZ), within TC3, and Thailand domestic. Under piece concept, each piece is 23 kg / 50 lb for Premium Economy and Economy, 32 kg / 70 lb for Royal First, Royal Silk, and Premium Economy Plus. All classes: max 158 cm / 62 in total linear dimensions per bag (including wheels and handles). Included-piece count varies by fare tier, so no second-bag fee is listed here; confirm via fare rules or booking. Routes not yet on piece concept and pre-March-2026 tickets still use weight concept: Economy Saver/Standard 23 kg total, Flexi 30 kg, Full Flex 30 kg, Economy Plus 35 kg, Royal Silk 40 kg, Royal First 50 kg. Star Alliance Gold adds +20 kg; Royal Orchid Platinum adds +30 kg.

Ways to skip the Thai Airways checked bag fee

  1. Pack carry-on only. Confirm your bag fits the Thai Airways carry-on size.
  2. Check your Royal Orchid Plus status. See whether your tier includes a free checked bag on Thai Airways.
