The market-low column is the cheapest fare in our Travelpayouts cache on that corridor across all carriers, not a Thai Lion Air-only price — use it as a floor when comparing.
A network across many countries means many rulebooks. Thai Lion Air’s corridors in our catalogue touch 1 country: Thailand. Each has its own regulator, so passenger rights attach not only to the airline but to the country the flight departs from. Two flights on the same airline can carry completely different entitlements.

Thai Lion Air’s checked-baggage baseline is 15 kg.
That 7/10 is our own score. Brand strength is an editorial assessment by our team for the Thai market, used to decide how deeply we cover a carrier. It is not a safety rating, not a punctuality rating and not a service score from any independent body. We say so here so you can weigh the number correctly.
The 15% infant fare does not include a seat. It applies to a lap infant travelling without its own seat. Want a separate seat or a car seat and the ticket becomes a child fare, priced as a share of the full fare, with an adult-style allowance. On long sectors the number of positions where a bassinet can be fitted is limited and they go early — request one as far ahead as possible if you need it.
Thai Lion Air network & booking
Thai Lion Air’s network in our catalogue covers 6 corridors, based at Bangkok (DMK), Hat Yai (HDY), Krabi (KBV), Chiang Rai (CEI), Ubon Ratchathani (UBP) and Khon Kaen (KKC). Cached fares across them run from ฿1,764 (BKK–HKT) to ฿2,525 (BKK–CNX).
In this catalogue Thai Lion Air’s network reaches 6 destinations across 1 country — Thailand. Most corridors serve ASEAN & regional leisure travellers. All fares are shown in Thai baht (THB); compare live prices and schedules for each city pair on the route pages, and infant fares run about 15% of the adult fare.
The wide range reflects distance, not pricing policy. This network mixes short and long corridors, and fares track cost per seat-kilometre before anything else. Comparing prices across routes in one table tells you which corridor is cheaper, never which is better value. Use the individual route guides to compare within a single city pair — the only comparison that means something.
Our catalogue is not the airline’s full network. We build guides only for corridors relevant to travellers from Thailand. Thai Lion Air may operate many routes that never appear here, so an absent corridor is not evidence the airline does not fly it. Check the official schedule when planning anything that does not start in Thailand.
Passenger rights & compensation
Thai Lion Air appears on 6 corridors in our catalogue. Thai Lion Air is registered in Thailand and answers primarily to Thailand CAAT. The common misreading is that rights travel with the airline. In practice they change first with the country the flight departs from.
Thai Lion Air passenger protection is governed by Thailand CAAT — covering care, rerouting and refunds for cancellations/long delays. There is no fixed EU261-style cash schedule; check the regulator’s official terms before filing.
Baggage runs on a separate legal frame. Liability for baggage lost, damaged or delayed on an international journey sits under the Montreal Convention 1999 where both states are parties. Caps are denominated in SDR and revised periodically, so only the current figure is usable. Crucially this is independent of delay compensation: you can have no compensation claim and still have a baggage claim.
Collect evidence from day one. Whichever frame applies, the burden of proof sits with the passenger. Keep every boarding pass, the airline’s own delay notice or message, receipts for food and accommodation while you waited, and the actual arrival time against the scheduled one. Most rejected claims fail not because there was no right but because nothing documented what actually happened when.
How Thai Lion Air fits travellers
Thai Lion Air appears on 6 corridors in our catalogue. Thai Lion Air’s corridors in our catalogue distribute across passenger clusters as: ASEAN & regional leisure (6), with 2 flagged as labour/migrant corridors. The split is computed from our own route data, not from the airline’s marketing.
Thai Lion Air’s catalogued routes matter most to the ASEAN & regional leisure segment(s). Its Bangkok (DMK), Hat Yai (HDY), Krabi (KBV), Chiang Rai (CEI), Ubon Ratchathani (UBP), Khon Kaen (KKC) hub(s) are the main transit points. Compare schedules, baggage and fares against other carriers on the route pages before booking.
Your rights do not change with the cluster you fall into. The segmentation on this page is an editorial tool for deciding what to explain where. It is not a fare class and it has no legal effect. Two passengers on the same flight who paid different prices for different reasons hold identical statutory rights. What actually changes them is the departure country, the carrier’s nationality and whether the flight is scheduled or chartered.

Thai Lion Air in our fare record
Across 38 weekly fare captures on corridors Thai Lion Air serves, the code SL appears as the carrier holding the low 1 times — 3%. The cheapest such reading was ฿2,471 on BKK–HDY in week 2026-W31. Those corridors carry about 595 weekly departures counting every carrier on the same city pairs.
Where this carrier holds the low most often. BKK–HDY (1×). On those corridors Thai Lion Air is the reference price to beat. Elsewhere in the network the low falls to other carriers more often, which is why checking two or three airlines before booking still pays even when you already intend to fly this one.
What this measures, and what it does not. We capture each corridor’s lowest fare once a week and record which carrier code that value was attached to. The 3% figure therefore says how often this airline surfaced as the cheapest option in the window we observed. It does not say whether the airline is expensive or cheap on average, and it says nothing about what the others charged that week. A low share is not evidence of a high price.
