Thai Airways Baggage Fees (2026)
Quick summary
Thai Airways is a full-service carrier. From 2 March 2026 it switched Economy from a pure weight allowance to a piece concept: most Economy fares get 1 free checked bag (Flex fares get 2), each up to 23 kg and 158 cm linear.
The bottom line on Thai Airways baggage
Thai Airways is a bundle-style full-service carrier: your carry-on and personal item ride free, and most Economy fares now include one checked bag, so only travelers needing a second bag pay extra. The trap is the March 2026 switch from weight to a piece concept — on Saver and Standard fares a second bag is a separate charge, not just added weight.
The reliable way to save is to book a Full Flex fare when you genuinely need two bags, prepay any excess on thaiairways.com rather than at the counter, and add your Royal Orchid Plus number at booking to lift your allowance.

Hidden pitfalls most travelers miss
- From 2 March 2026 Economy switched from a weight allowance to a piece concept, so on Saver and Standard fares a second bag is a separate charge — not just extra weight on your existing bag.
- Excess and extra bags are cheaper bought on thaiairways.com in advance; buying at the airport counter costs more.
- Adding your Royal Orchid Plus number at booking can raise your free allowance, so link it before you fly.

Other common fees
| Excess weight (over 23 kg per piece) | Per-kg or heavy-bag fee, varies by route |
| Sporting / oversized equipment | Pre-declare; special handling fee may apply |
How to avoid extra fees
- Pre-purchase any extra or excess baggage on thaiairways.com — airport rates are higher.
- From March 2026 the piece concept applies, so a single 23 kg bag is fine but a second bag costs extra on Saver/Standard fares — book Flex if you need two bags.
- Keep each checked piece under 23 kg and 158 cm linear to avoid heavy/oversized surcharges.
- Royal Orchid Plus status can raise your free allowance, so add your number at booking.
