Flying from Kolkata to Bangkok
In short
Multiple airlines fly nonstop from Netaji Subhas Chandra Bose International Airport (CCU) in Kolkata to Bangkok. Bhutan Airlines, IndiGo, Thai Airways International and Thai VietJet Air land at Suvarnabhumi (BKK), and Thai AirAsia and Thai Lion Air at Don Mueang (DMK). The 1,636 km flight takes about 2 hours 35 minutes. For people in West Bengal and north-east India, Bangkok is the easiest beach and shopping break abroad.
Metro to the Dum Dum terminal
The airport is at Dum Dum, about 16 km from Dalhousie Square. Jai Hind metro station, on the Yellow and Orange Lines, serves the integrated terminal, which opened in 2013 and handles both domestic and international flights. Around 21.8 million passengers used the airport in 2024–25. IndiGo and Air India Express have bases there.
Bhutan Airlines A319s and the low-cost options
Thai Airways International and Bhutan Airlines include a checked bag. Bhutan Airlines flies a Paro, Kolkata and Bangkok service on Airbus A319s with 12 business seats. IndiGo, Thai VietJet Air, Thai AirAsia and Thai Lion Air price the seat alone, with bags and meals as extras. SpiceJet joins the route on 25 October 2026.
Rail Link and taxis from Suvarnabhumi
Suvarnabhumi lies about 25 km east of central Bangkok, in Samut Prakan province. The Airport Rail Link runs to Phaya Thai in about 27 minutes and meets the BTS Skytrain; Makkasan connects to the MRT Blue Line. Metered taxis and Grab wait outside arrivals. For the beach, coach 389 runs to Pattaya for 130 baht.
Don Mueang, in the north, is Bangkok's low-cost hub, with about 31.7 million passengers in 2025. The SRT Dark Red Line stops at the airport, and bus A4 goes to Khaosan Road and Sanam Luang for 50 baht. A Royal Thai Air Force golf course lies between its two runways, which you may spot on landing.
Thai entry rules depend on nationality; see our Thailand visa page. Every foreign visitor completes the Thailand Digital Arrival Card within 72 hours before landing.
Dhaka flights from Bangkok or Kolkata
The Dhaka flights on Biman, US-Bangla and Thai Airways leave from Suvarnabhumi (see Bangkok to Dhaka flights). From Don Mueang, allow time to cross the city and check in again. Kolkata also has its own flights: see Kolkata to Dhaka flights.
Clocks go forward 1 hour 30 minutes on landing in Thailand.

Frequently Asked Questions (FAQs)
Getting there
Flights land at both Bangkok airports: several airlines at Suvarnabhumi, and Thai AirAsia and Thai Lion Air at Don Mueang. SpiceJet starts 25 October 2026. Schedules change by season, so check the flights for your dates in the search above.
About 2 hours 35 minutes in the air. The two airports are 1,636 km apart in a straight line; actual times vary a little by airline, aircraft and wind.
Both. A number of airlines use Suvarnabhumi (BKK); two use 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.
General
The clock moves one hour and 30 minutes forward on landing in Thailand (Thailand is UTC+7). Neither side uses daylight saving, so the gap stays the same all year.
A passport that meets Thailand's entry rules for your nationality, plus the Thailand Digital Arrival Card, which every foreign visitor completes within 72 hours before landing. Check whether you need a visa on our Thailand visa page.
Yes; see Kolkata 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. IndiGo, Thai VietJet Air, Thai AirAsia and Thai Lion Air are low-cost carriers 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.
Cancellations & changes
SpiceJet starts 25 October 2026. Airlines publish these changes in advance, but dates can move, so check the schedule before you book.
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 IndiGo, Thai VietJet Air, Thai AirAsia and Thai Lion Air, meals are bought online or on board; check the menu for halal options.
