Flying from Kathmandu to Bangkok
In short
Nepal Airlines, Thai Airways International and Thai AirAsia fly nonstop from Tribhuvan International Airport (KTM) in Kathmandu to Bangkok. The 2,229 km flight takes about 3 hours 15 minutes. It is a busy route for Nepali workers, students and holidaymakers, and for travellers ending a trek with a few days in Thailand.
Nepal Airlines and Thai to BKK, Thai AirAsia to DMK
Nepal Airlines and Thai Airways arrive at Suvarnabhumi (BKK); Thai AirAsia arrives at Don Mueang (DMK). The full-service fares include a checked bag and meal. Thai AirAsia's base fare covers a cabin bag only, so add hold luggage when you book if you are carrying trekking kit home.
Tribhuvan's single runway shared with mountain flights
Tribhuvan International Airport is about 5.6 km east of central Kathmandu, and taxis from Thamel take 20 to 40 minutes. It operates on a single runway of about 3,050 m, shared with domestic flights from Lukla, Pokhara and other mountain airstrips. Trekkers flying out of Lukla should plan at least one buffer day before the Bangkok flight, as mountain weather often grounds those small aircraft.
TDAC and the 30-day visa exemption for 60 countries
Complete the Thailand Digital Arrival Card (TDAC) on tdac.immigration.go.th. It is free, opens three days before arrival, and applies to every non-Thai traveller.
Since 15 September 2026, a 30-day visa exemption covering 60 countries and territories has replaced the 60-day scheme. Nepal was not named in that announcement, so Nepali passport holders should check the Thai e-Visa portal, and our Thailand visa page explains the steps. Trekkers from Europe or the Americas should confirm their own category too, as the list changed.
Rail Link, taxis and bus 389 from Suvarnabhumi
Suvarnabhumi lies about 25 km east of central Bangkok. The Airport Rail Link runs to Phaya Thai in about 27 minutes and connects with the BTS Skytrain; Makkasan links to the MRT Blue Line. Taxis and Grab wait outside arrivals. For a beach stop, bus 389 runs to Pattaya from Exit 8 on the first floor between 10:00 and 18:00 for 130 baht.
Gate 6 buses and the Red Line from Don Mueang
The A1 and A2 buses leave Gate 6 of Don Mueang's international terminal for 30 baht, the A1 to Mo Chit 2 and the A2 to Victory Monument, both via BTS Chatuchak. The SRT Red Line also runs south to Krung Thep Aphiwat Central Terminal, where it meets the MRT Blue Line, with trains from about 05:00 to 23:45.
Minibus 555 to Suvarnabhumi for flights to Dhaka
The Dhaka flights on Biman, US-Bangla and Thai Airways leave from Suvarnabhumi (see Bangkok to Dhaka flights). If you land at Don Mueang, minibus 555 crosses to Suvarnabhumi between 06:30 and 20:00 for up to 60 baht, but give yourself time for the road and a new check-in. Kathmandu also has direct flights of its own: see Kathmandu to Dhaka flights.

Frequently Asked Questions (FAQs)
Getting there
Flights land at both Bangkok airports: a few airlines at Suvarnabhumi, and Thai AirAsia at Don Mueang. Schedules change by season, so check the flights for your dates in the search above.
About 3 hours 15 minutes in the air. The two airports are 2,229 km apart in a straight line; actual times vary a little by airline, aircraft and wind.
Both. Rival airlines use Suvarnabhumi (BKK); Thai AirAsia uses Don Mueang (DMK). The airports are on opposite sides of the city, so check the code on your ticket.
Suvarnabhumi lies about 25 km east of central Bangkok. The Airport Rail Link runs to Phaya Thai in about 27 minutes and meets the BTS Skytrain there; Makkasan station connects to the MRT Blue Line. Metered taxis and Grab wait outside arrivals. Don Mueang is north of the city. The SRT Dark Red Line stops at the airport and runs to Krung Thep Aphiwat Central Terminal (Bang Sue), where it meets the MRT Blue Line; airport buses and metered taxis cover the rest of the city.
Yes. Biman, US-Bangla and Thai Airways fly Bangkok to Dhaka from Suvarnabhumi. If you land at Don Mueang, allow at least four hours to transfer by road and check in again. On separate tickets you clear Thai immigration and collect your bag, so you need a Thai visa. See Bangkok to Dhaka flights.
Tribhuvan sits in a valley and handles heavy traffic on a single runway, and morning haze or fog in winter can slow arrivals. Leave slack in any onward plans.
General
The clock moves one hour and 15 minutes forward on landing in Thailand (Thailand is UTC+7). Neither side uses daylight saving, so the gap stays the same all year.
Yes; see Kathmandu to Dhaka flights. Going via Bangkok is worth it if you want a few days in Thailand on the way home.
What's included
It depends on the airline. Thai AirAsia is a low-cost carrier whose basic fares include only a cabin bag, so add checked baggage when you book. The full-service airlines normally include a checked bag; the allowance is shown on your booking.
Visa & documents
It depends on your passport. Thailand's new 30-day exemption covers 60 countries and territories from 15 September 2026, and Nepal was not named in the announcement, so Nepali citizens should check the Thai e-Visa portal. All foreign arrivals file the free Thailand Digital Arrival Card.
Stay & facilities
On the full-service airlines, request a Muslim (halal) meal when you book or at least 24 hours before departure through the airline's manage-booking page. On Thai AirAsia, meals are bought online or on board; check the menu for halal options.
