Cheap flights from Kolkata to Bangkok

Demand on this route follows school holidays, Christmas and New Year and Bangkok's peak season, so the cheapest month is not always the quietest week. December is the cheapest month in the fare data, yet flights around the holidays still fill quickly, so compare dates across the month rather than assuming one flat price. Midweek departures can price lower than weekend ones, and early or late flights can help if the timing suits you. If your dates are flexible, test neighbouring months too, because a small shift can change both the fare and the connection time.

The biggest difference you feel is between a fare that bundles checked baggage, meals and seat choice and one that charges for each extra, so read the fare rules before comparing headline prices. Direct flights operate on this route, but not every listed carrier sells a nonstop on every date, and some itineraries connect through another city. Among the names you may see are Thai Lion Air, Thai Vietjet Air, Bhutan Airlines, Thai AirAsia, Indigo, Air India, Thai Airways Intl, Hahn Air Systems, US-Bangla Airlines and Air India Charters. Low-cost and full-service styles both appear in that list, and the ticket details show which is which.

Arriving late in the day changes the transfer: both Bangkok airports sit outside the centre, public transport thins out after dark, and a tired arrival makes the wrong-airport mistake more likely. Suvarnabhumi International and Don Mueang International are not interchangeable, since they sit on different sides of the city, so confirm the arrival airport on your itinerary before you leave Kolkata. Trains, taxis and airport buses serve both, but late arrivals should allow extra time and check which services are still running. If you land at the airport you did not plan for, expect a cross-city ride before you reach your hotel.

Country facts: Wikidata

• Check whether a cheap fare is actually two separate tickets, because a missed connection then becomes your problem.
• Weigh your bags against the low-cost allowance before you pay, since excess charges are collected at the airport.
• Confirm which Bangkok airport your itinerary uses, because Suvarnabhumi International and Don Mueang International are far apart.
• Carry the documents Thailand requires for your nationality and keep them handy for check-in and arrival.
• Compare December dates with neighbouring months, because the cheapest month is not automatically the cheapest day.
