Thai Lion Air Baggage Policy: Allowance, Fees & Weight Limits 

Thai Lion Air allows 7kg of cabin baggage (56 x 36 x 23cm) on every fare. Checked baggage depends on your fare: Lion Saver includes none, Lion Value includes 15kg (domestic) or 20kg (international), and Lion Flexi includes 25-30kg. Prepaid excess baggage starts at 375 THB for 5kg domestic, far cheaper than paying at the airport counter.

Thai Lion Air keeps its base fares low by unbundling baggage from the ticket price. That works in your favor if you travel light, but it can catch you off guard if you show up with an unplanned suitcase. Understanding exactly how much you can carry, what’s included in each fare, and how much extra weight costs is the difference between a smooth check-in and an expensive surprise at the counter.

.What is Thai Lion Air’s baggage allowance?

Thai Lion Air’s baggage allowance depends on your fare tier. All passengers get 7kg of cabin baggage regardless of fare. Checked baggage is only included on Lion Value (15-20kg) and Lion Flexi (25-30kg) tickets  Lion Saver fares carry cabin baggage only, with checked bags purchased separately.

Here’s how the three fare tiers compare:

One notable exception: on the Bangkok–Seoul route, Lion Flexi’s international checked allowance is capped at 20kg (2 pieces) instead of the usual 30kg. These new fare families apply to bookings and travel from 16 July 2026 onward; tickets issued before that date follow the older structure of 10kg (domestic) or 20kg (international) checked baggage.

How much is Thai Lion Air baggage weight, and what happens if I go over?

Thai Lion Air charges for excess weight at two very different rates depending on where you buy it. Prepaid online, 20kg of extra domestic baggage costs just 660 THB. Bought at the airport counter, the same 20kg costs 7,000 THB  more than ten times as much.

Here are the official prepaid baggage rates, which you can purchase through lionairthai.com, the call center, Line (@lionairgroup), or ticket counters at least 3 hours before departure:

Compare that to counter rates: 350 THB per kg on domestic routes and 525 THB per kg on international routes within Southeast Asia and North Asia. Run the math on a 10kg overage on a domestic flight, and the difference is stark  475 THB prepaid versus 3,500 THB at the counter. That’s a savings of over 86%.

Special case for Seoul flights: Before March 1, 2026, prepaid baggage wasn’t offered on Bangkok–Seoul routes at all. From March 1, 2026, only the 20kg prepaid option is available on this route.

What is Thai Lion Air’s checked baggage size and weight limit?

Thai Lion Air caps checked baggage at 32kg per piece, with a combined maximum of 45kg per passenger across all pieces. If a single bag exceeds 32kg, it won’t be accepted at check-in regardless of your remaining allowance  you’ll need to redistribute the weight into a second bag.

A few rules worth knowing before you pack:

• Prepaid baggage can be purchased in multiple transactions, but the running total can’t exceed 45kg
• Each individual piece is still capped at 32kg, even if you have unused allowance remaining
• Sporting equipment is accepted as checked baggage within your existing allowance  no separate sports baggage fee is published
• If your final checked weight exceeds your free allowance plus any prepaid baggage, standard excess fees apply at the airport

What size carry-on bag does Thai Lion Air allow?

Thai Lion Air’s carry-on allowance is 7kg, with maximum dimensions of 56 x 36 x 23cm. This applies uniformly across Lion Saver, Lion Value, and Lion Flexi fares  no fare tier gets a larger cabin allowance. Bags that don’t comply are transferred to the hold as checked baggage, which may trigger excess fees if you haven’t purchased checked allowance.

You’re permitted one cabin bag plus one personal item. While no separate size limit is published for the personal item, it still needs to fit comfortably under the seat in front of you. Liquids, gels, and aerosols in your carry-on must be in containers of 100ml or less, packed into a single transparent resealable bag with a maximum 1-liter capacity.

Is it cheaper to buy Thai Lion Air baggage online or at the airport?

Buying baggage online before departure is dramatically cheaper than paying at the airport. A 15kg domestic add-on costs 600 THB prepaid versus 5,250 THB at the counter  a difference of 4,650 THB for the exact same weight. This pricing gap holds across every weight tier and route type Thai Lion Air publishes.

The lesson here is simple: if there’s any chance you’ll be over your free allowance, buy the extra weight online at least 3 hours before your flight. Waiting until you’re at the counter means paying the full per-kilogram penalty rate, which the airline uses partly to encourage advance purchasing.

Frequently Asked Questions

Thai Lion Air will not accept a single piece over 32kg. You’ll need to redistribute the weight across multiple bags before check-in.

Is prepaid baggage refundable if I don’t use it?
No. Prepaid baggage (Lion Baggage) is non-refundable except when Thai Lion Air changes the schedule or cancels the flight.
