Thai Lion Air Baggage Fees (2026)
Quick summary
Thai Lion Air (code SL) is a Thai low-cost carrier that, unlike ultra-budget airlines, includes free checked baggage on many fares. The catch is the fare type: the cheapest 'Lion Promo' tickets carry no free checked bag on most routes, while 'Lion Economy' fares include 10kg (domestic) or 20kg (international). Every passenger gets a free 7kg cabin bag. Prepay extra weight online (up to 30kg per passenger) well before the airport, because paying excess at the counter is far more expensive.
The bottom line on Thai Lion Air baggage
Thai Lion Air is a low-cost carrier that behaves more generously than most, bundling free checked baggage into many fares rather than stripping everything out. The catch is the fare label: the cheapest Lion Promo tickets carry no free checked bag on most routes, while Lion Economy includes 10kg domestic or 20kg international, so the same flight can cost very differently depending on which fare you click.
The surest way to save is to book Lion Economy when you need a bag and prepay any extra weight online at least three hours out — airport excess runs about ฿350/kg domestic and ฿525/kg international, several times the online price.

How to avoid extra fees
- Check the fare type before booking: a cheap 'Lion Promo' ticket usually has zero free checked bag, while 'Lion Economy' includes 10kg (domestic) or 20kg (international).
- Prepay extra baggage online at least 3 hours before departure — airport excess runs about ฿350/kg domestic and ฿525/kg international, which adds up fast.
- Keep your cabin bag to 56 x 36 x 23 cm and 7kg; the personal item (laptop or handbag) counts toward that same 7kg.
- No single bag may exceed 32kg, and your total (free plus prepaid) is capped at 45kg — split heavy loads across two bags.
- On a few long-haul routes (e.g., Bangkok to Seoul, Mumbai, Bengaluru, Kochi) even Lion Promo includes 20kg, so verify the specific route before paying extra.
- Weigh your bag at home; a small overage caught at the counter costs several times more than buying the same weight online in advance.
- Lion Baggage and Lion Seat purchases are non-refundable unless Thai Lion Air changes or cancels your flight.
