Thai Lion Air is a low-cost carrier, and its cheapest fares price baggage à la carte. The base ticket gets you one cabin bag up to 7 kg; a checked bag is an extra you buy on top, with the price varying by route, weight tier and whether you pre-purchase or pay at the airport.
The headline rules: cabin bag up to 56 × 36 × 23 cm and 7 kg (plus a laptop bag or handbag), checked allowance sold by weight (no single piece over 32 kg), excess charged at THB 350/kg domestic and THB 525/kg international. Some bundled fares and routes include a free checked allowance.”

The combined cabin + personal item weight is policed against the 7 kg cabin limit on tight aircraft, so pack the under-seat item light. |

What you actually get on a cheap fare
What you actually get on a Thai Lion Air deal fare: one 7 kg cabin bag and nothing in the hold. The cheapest (Promo) ticket bundles no free checked baggage — that is the lever Thai Lion Air uses to advertise the low headline price.
For a deal to be worthwhile, budget the bag in upfront. Pre-purchase the checked allowance online (vouchers from ~THB 150 and tiered by weight) at least 3 hours before departure — paying at the airport means the per-kg excess rate (THB 350 domestic, THB 525 international), which can cost more than the fare itself. Travelling cabin-only at 7 kg is the move that keeps the advertised price honest.
Oversize, sports & special items
Oversize, sports & special items: any single checked piece is capped at 32 kg and combined dimensions of 81 × 119 × 119 cm — heavier or larger items must be split or arranged in advance. Bicycles, golf clubs, dive gear, surfboards and musical instruments are carried as part of (or in addition to) your weight allowance and should be declared and paid for ahead of travel; an instrument too heavy/large for the cabin needs its own seat or hold space.
Buying baggage: add allowance during booking, via Manage Booking, or through the call center. Prepaid baggage must be arranged at least 3 hours before departure. The call center may add a processing fee (around THB 100 per passenger on international bookings).
2026 route note: for bookings made on or after 1 March 2026, only the 20 kg prepaid tier is available on Bangkok (DMK)–Seoul (ICN). Always check the exact allowance and price shown for your route at the payment step, as figures differ between domestic, intra-ASEAN and longer international sectors.
Baggage by region & route
Thai Lion Air (Lion Group) includes a modest free checked allowance on most fares (around 10–15 kg) — more than a pure budget carrier but less than a full-service airline.
| Region / route | Cheapest economy checked allowance | System |
|---|---|---|
| Domestic economy | 15 kg included | Weight |
| International economy | 10–20 kg by route | Weight |
✈️ Thai Lion Air is not in an airline alliance — no cross-carrier elite baggage benefit.
Larger allowances are sold as paid add-ons; pre-book online. Allowances are for the cheapest bookable economy fare, web-verified June 2026; always confirm on your e-ticket as fares and routes change.
Frequently asked questions
Is a checked bag included in Thai Lion Air's cheapest fare?
No. The cheapest Promo fare includes only a 7 kg cabin bag; checked baggage is bought separately. Some bundled Economy fares and routes do include a free checked allowance (often around 10 kg domestic or 20 kg total international), but it is not guaranteed.
What is the Thai Lion Air cabin baggage size and weight limit?
One cabin bag up to 56 × 36 × 23 cm and 7 kg, plus one laptop bag or one handbag. The 7 kg weight limit is enforced, so keep within it to avoid being asked to check the bag at the gate.
How much does extra checked baggage cost on Thai Lion Air?
Prepaid baggage vouchers come in 5, 10, 15, 20, 25 and 30 kg tiers starting from roughly THB 150, with the price scaling by weight and route. If you pay at the airport instead, excess is THB 350/kg on domestic flights and THB 525/kg on international flights (THB 400/kg on Bangkok–Kuala Lumpur).
What is the maximum weight for a single checked bag?
No single checked piece may exceed 32 kg, and its combined dimensions must not exceed 81 × 119 × 119 cm. Heavier or larger items must be split into multiple pieces or arranged as special/oversize baggage in advance.
When can I buy prepaid baggage for Thai Lion Air?
You can add baggage during booking, through Manage Booking, or via the call center, but it must be arranged at least 3 hours before departure. Buying online in advance is much cheaper than the airport excess rate. The call center may add a processing fee (about THB 100 per passenger on international routes).
Can I bring a personal item in addition to my cabin bag?
Yes. In addition to the 7 kg cabin bag, Economy passengers may bring one laptop bag or one handbag on board. There is no separate generous personal-item allowance like some full-service carriers, so keep the under-seat item small.
Are sports equipment and musical instruments allowed?
Yes, but they count toward your baggage weight allowance and should be declared and paid for in advance. The 32 kg single-piece and 81 × 119 × 119 cm dimension caps apply; an instrument too large for the cabin must travel in the hold or on its own purchased seat.
Did Thai Lion Air change any baggage rules for 2026?
Yes — for bookings made on or after 1 March 2026, only the 20 kg prepaid baggage tier is available on the Bangkok (DMK)–Seoul (ICN) route. General excess rates remain THB 350/kg domestic and THB 525/kg international.
