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.
