For Chiang Mai, the Bangkok departure airport matters as much as the fare. Compare every airline together, note BKK vs DMK for each option, then open the best option on the airline's own site in THB and compare the final total with baggage. No live fare is published here.
How to buy cheap from Bangladesh (3 steps)
- Compare every airline together first. Open the Cheap Ticket Finder search tool on our homepage, set From = Bangkok and To = Chiang Mai, pick your dates, and open the on-site flight search. Use it to compare airlines, airports and times. The on-site search does not sell tickets; the provider shows the final total.
- Then buy on the official airline site in local currency. Open the same flight on the airline's own site below and check it in THB (Thai baht). Match flight number, airport code, date, passenger name exactly as in the passport, and baggage — then compare the final charged total. Do not assume a currency or location change always lowers the fare; the payment-page total is final.
- If your Bangladesh card fails, fix the card settings first — then re-check. Payment can fail without passport endorsement / travel quota, with online or foreign transactions off, or at OTP/3D-Secure. Check your own bank app or bank first. Bangladesh Bank guidance links international card payment to passport endorsement and travel quota (limits must be confirmed with your own bank): Bangladesh Bank foreign-exchange guidance (PDF). Never use someone else's card, an unknown virtual-card seller, or a VPN trick to pretend to be a local resident — we never recommend those. If a seller offers this leg, verify that specific route and date before paying; we do not claim every seller sells every domestic leg.

Which airlines — official sites only
Thai AirAsia, Thai VietJet, Thai Lion Air and Nok Air are low-cost airlines flying Bangkok to Chiang Mai. Thai Airways and Bangkok Airways also fly Bangkok to Chiang Mai, so compare the Bangkok departure airport (BKK or DMK), baggage and the final total for your dates.
- Thai AirAsia (FD) Low-cost: Mainly DMK, some domestic from BKK — check the airport on your flight. Official: AirAsia flights. From Bangladesh, an international card is the realistic payment path; Thai local counter/bank options are for people in Thailand. Official payment/support source.
- Nok Air (DD) Low-cost: DMK-based. Official booking/payment guide: Nok Air — how to book and pay (cards and other options listed there; counter/ATM requires being in Thailand).
- Thai Lion Air (SL) Low-cost: DMK-based. Official: lionairthai.com. Foreign-card success was Unknown in our research — confirm at checkout only.
- VietJet Thailand (VZ) Low-cost: BKK-based, which may avoid an airport change after arriving from Dhaka. Official: vietjetthai.com; group payment methods (verify on the Thai site before paying): VietJet payment methods.
Airport warning
Baggage box
AirAsia cabin baggage (verified): 2 cabin bags totalling 7kg plus a small personal item — official rules. For the other airlines, fare-by-fare baggage was not verified as a single number in our research — confirm cabin and checked allowances for your exact fare before paying.
Add checked baggage online before comparing. The lowest headline fare can stop being cheapest once bags, seat and payment fees are added.
Separate-ticket & transit/entry caution
Two tickets = two contracts. If the first flight is late, the second airline is not obliged to rebook you free and the second fare can be lost as a no-show. With checked bags on separate tickets you may need immigration → baggage reclaim → check-in again, so keep a large buffer; arriving the night before the domestic leg is our safer advice (guidance, not an official airline rule).
Separate tickets / BKK↔DMK changes can mean entering Thailand. Do not assume airside transit or any entry eligibility on a separate ticket.
No verified official Thai entry link is provided in our research for this page, so none is guessed here. Check official Thai immigration/government sources and the airline for your passport and itinerary before you book.
Spell the passenger name exactly as in the passport — low-cost airlines can charge for name correction or refuse boarding (the amount varies, so we do not print a fee here). Cheap low-cost fares are often non-refundable and change fees can be high — read the fare rules before paying. Keep your booking confirmation and PNR safely with you; never send us passport or card images.
FAQ
What is the Bangkok to Chiang Mai ticket price today?
We do not publish a fixed or live price on this page. The fare depends on your date, airline and fare family, and baggage can change the total. Use the search tool on our homepage, compare in the on-site flight search, then check the final payable total on the airline's payment page before you pay.
Does Cheap Ticket Finder sell tickets?
No. We do not sell tickets and we do not take payment. We help you compare and then link you to the on-site flight search and official airline sites, where booking and payment happen. Never send us passport, card or booking-login details.
What is the separate-ticket risk?
Two separate tickets are two separate contracts. If the first flight is delayed, the second airline does not have to rebook you for free and you may lose the second fare as a no-show. On separate tickets, leave a large buffer — for an international arrival followed by this domestic leg, arriving the night before is the safer plan in our guidance, not an official airline rule.
Why check the local currency on the airline site?
Our homepage on-site flight search shows provider results for the route and dates you pick. Airline sites may show this domestic leg in THB (Thai baht). Display currency and the currency your card is finally charged in can differ, and your bank may add conversion costs — so match the flight, baggage and final charged total on the payment page, and do not assume changing currency or location always makes a fare cheaper.
We do not sell tickets. Prices change — the provider's payment-page total is final.
