Thai Airways Checked Baggage: Allowances, Fees & Status Perks
Thai Airways checked baggage by ticket date, fare and cabin: current piece allowances, status conditions, infant equipment and itinerary-specific excess.
Thai Airways Checked Baggage Rules
Check ticket issuance and travel dates before using a weight allowance. THAI introduced a piece-based regime for travel from2 March2026, subject to the published ticket-sale, issuance and reissuance dates. Older weight tables remain on the same page; they are not the default for every current booking.
Current piece table
| Cabin/fare | Purely domestic | International |
|---|---|---|
| Economy | 1×23 kg | Standard/Saver normally1×23 kg; Flexi/Full Flex2×23 kg |
| Premium Economy | 1×23 kg | 2×23 kg |
| Royal Silk / Premium Economy Plus | 1×32 kg | 2×32 kg |
| Royal First | Check booking | 3×32 kg; redemption2×32 kg |
The page flags destinations where Saver includes no checked baggage. Each piece is limited to158 cm total including wheels and handles. Check the exact ticket rather than applying an old universal30 kg or203 cm rule. Premium Economy Plus is aircraft-specific.
For the new regime, the published status table adds two pieces for ROP Platinum or one for ROP/Star Alliance Gold and ROP Silver, with23/32 kg limits depending on cabin and tier. These are checked allowances, not extra cabin bags. Confirm eligibility rather than adding old weight-system bonuses.
Dates and connections
The official agent notice specifies25 November2025 for sales/issuance/reissuance of wholly unused tickets, with travel from2 March2026. The public page separately gives28 November2025 for the TC3–TC1 introduction. Older tickets, reissues and mixed-airline journeys need the booking’s actual baggage rule. A stopover may trigger a new assessment. Do not assume the operating airline alone decides every through-checked allowance.
Children, special equipment and excess
The piece table includes one infant checked piece at the listed cabin weight. The reviewed equipment note permits one own-use foldable stroller, car seat or wheelchair without an additional charge; it does not promise one of each or aircraft-door delivery.
Ask THAI for the itinerary-specific quote and acceptance conditions before bringing extra, heavy or oversized pieces. Removed fee estimates are not verified prices. Approval for sports, medical or child equipment is a separate question from the ordinary bag allowance.
Measure and weigh each checked piece separately. For hand baggage, use the THAI cabin guide and checker; the checker does not calculate checked-baggage charges.
