Thai Lion Air is a budget friendly airline, but knowing their baggage rules ahead of time can save you from surprises at the airport.
Here is everything you need to know about their carry-on and checked baggage policies, plus how strict they are with luggage size and weight.
Let’s dive right in.
Thai Lion Air Carry On Baggage / Unchecked Baggage

All passengers are allowed one carry-on bag, which must meet the following size and weight limits:
- Maximum weight: 7 kg (15.43 lbs)
- Maximum dimensions: 30 cm x 40 cm x 20 cm (11.81 in × 15.75 in × 7.87 in.)
Your bag must fit either in the overhead bin or under the seat in front of you.
In addition to your carry-on, you can bring one personal item for free. This includes things like a handbag, laptop bag, small backpack, overcoat, book, or umbrella.
Thai Lion Air may check your bag size at the gate, so make sure it meets their requirements to avoid extra fees.
Thai Lion Air Check In Baggage
The checked baggage allowance depends on your ticket type and destination:
- Domestic Flights:
- Premium Economy: 1 checked bag up to 20 kg (44.09 lbs.)
- Economy Class: No free checked baggage
- International Flights:
- Premium Economy: Up to 30 kg (can be split into 2 bags)
- Economy Class: No free checked baggage (except for Bangkok-Colombo route)
Important: Your checked baggage must have an identification tag with your name. Thai Lion Air will try to transport your bag on the same flight, but if operational issues arise, they will deliver it as soon as possible.
For safety reasons, no single checked item can exceed 32 kg or have combined dimensions larger than 81 cm x 119 cm x 119 cm (31.89 in × 46.85 in × 46.85 in.).
Mobility equipment is exempt from this rule.
Thai Lion Air Checked Baggage Fees
Fees depend on your route. Here’s a breakdown:
- Domestic Flights: You can pre-purchase baggage at about $1 per kg (30 Baht per kg), meaning 20 kg costs around $13 (405 Baht).
- International Flights: Checked baggage fees are 1,300 Baht ($43) for 30 kg.
Booking luggage online in advance is cheaper than paying at the airport.
Thai Lion Air Baggage Restrictions
For safety reasons, Thai Lion Air follows strict regulations for liquids, aerosols, and gels:
- Each container must be 100 ml or less.
- All containers must fit in one transparent, resealable plastic bag (max 1 liter capacity).
- You’re allowed one plastic bag per passenger.
- The bag must be presented separately during security screening.
- Duty free liquids must remain sealed in a security approved bag with proof of purchase.
- Exceptions apply for medications, baby food, and special dietary items.
How Strict Is Thai Lion Air With Baggage?
Expect airline staff to check your bags at the airport.
If your carry-on or checked bag exceeds the allowed weight or size, you’ll need to pay extra fees or check it in.
To avoid surprises, we recommend weighing and measuring your luggage before heading to the airport.
Final thoughts
Booking baggage online is the best way to save money, as fees at the airport can be higher.
Also, double check the weight limits, especially for checked luggage, to avoid unexpected charges.
Keeping personal items within the allowed size ensures a smoother check-in process.
If you’re unsure about your bag’s dimensions, consider using a luggage sizer at the airport.
A little preparation goes a long way in making your travel experience hassle-free.
I hope this helps
