Bangkok to Kolkata is one of the shortest international hops out of Bangkok, with around 21 flights a week and a block time of well under three hours. Eastern India sits close to Thailand, and the route carries a steady mix of Indian visitors heading for Thailand, Thai travellers bound for Kolkata, and passengers connecting onward across the region.

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.

All three fly direct, so the trip is short whichever you pick.

THB fares

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.

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.
