Airlines on this route
Three carriers fly BKK-CCU: IndiGo and Thai AirAsia operate it low-cost, while Air India runs a full-service cabin. The budget carriers sell a slim base fare with baggage added on, suited to a short trip with light luggage; Air India includes a checked allowance and meals. All three fly direct, so the trip is short whichever you pick.
Fare trends
Being a short sector with two low-cost carriers competing, BKK-CCU is among the cheaper international routes from Bangkok. Demand lifts around Durga Puja and the Indian wedding season, when booking a month or two ahead helps. For ordinary dates, two to four weeks of lead time is often enough for a low economy fare in THB, especially travelling with cabin baggage only.
Seasonality & best time to book
Bangkok–Kolkata fares move with demand. The cheapest windows fall outside school holidays, Songkran and New Year; book 4–8 weeks ahead for normal dates.
About Kolkata
Kolkata is the cultural capital of eastern India — the former colonial capital, known for its literature, theatre and intellectual life as much as for the Victoria Memorial and the tram-lined streets of the old centre. It is also a major medical-care hub for the region. For Thai travellers it is a close, affordable and characterful Indian city, and a practical gateway into India’s east.
