Which airlines fly Kolkata to Bangkok non-stop?
Thai Airways and IndiGo fly into Suvarnabhumi (BKK); Thai AirAsia flies into Don Mueang (DMK). Other Thai and Indian budget airlines have served this route at various times, so check current options for your dates. With several flights a day, Kolkata has some of the best Bangkok connectivity in India.
Best flight timings
Bangkok is 1 hour 30 minutes ahead of India. Late-night departures land around dawn, while morning flights land by early afternoon, leaving time for an evening river cruise on the Chao Phraya or a walk around Asiatique.
Baggage: full-service vs low-cost
Thai Airways includes meals and a checked bag. IndiGo sells meals and seats, so check your fare's checked allowance. Thai AirAsia's base fare usually covers cabin baggage only; add checked bags online in advance, where they cost less than at the airport.
Getting from the airport to the city
From Suvarnabhumi, the Airport Rail Link reaches Phaya Thai in 26 minutes for THB 45 (about ₹120), and a taxi to Sukhumvit or Silom costs THB 300–450 (₹800–1,200). From Don Mueang, take the SRT Red Line or a taxi for THB 250–400 (₹680–1,080). Pattaya is about 2 hours from Suvarnabhumi by road.
When to book and connecting options
Book 3–6 weeks ahead. Fares climb sharply around Durga Puja, Kolkata's biggest holiday window, and again at Christmas and New Year. July to September is usually cheapest. For Phuket, Krabi or Chiang Mai, connect on one Thai Airways ticket rather than self-transferring between BKK and DMK.
Tips for families and seniors
Fill the TDAC for every traveller, including infants. Request wheelchair help, as Suvarnabhumi's immigration hall is a long walk. Carry a printed hotel booking and return ticket for immigration.
