Four carriers fly Bangkok (BKK) to Mumbai (BOM) non-stop: Air India, IndiGo, Thai Airways and Thai Vietjet Air. All four depart from Suvarnabhumi (BKK) — unusually for a Thai low-cost carrier, Thai Vietjet uses BKK rather than Don Mueang on this route. Most services are A320-family narrowbodies, with the occasional widebody (A330 / B777 / B787) on Air India and Thai frequencies. The low-cost option alongside three full-service carriers gives this route a useful spread of price points.
The route covers about 3,034 km and non-stop flights take roughly 4h 45m gate to gate westbound, crossing the Bay of Bengal and peninsular India to the Arabian Sea coast. The eastbound return to Bangkok typically runs a little longer against the wind. Departures are spread across the day, including late-evening services that land in Mumbai overnight.
Fares rise over the October–January high season, Diwali, Thai festival periods and the year-end holidays, and soften through the monsoon. With a low-cost carrier in the mix, sale fares appear regularly, so booking 3–6 weeks ahead is usually enough outside peak dates. Mid-week and late-night departures are typically cheapest. Compare all four carriers in the FlightGPT search with flexible dates.
To save honestly: travel mid-week, consider Thai Vietjet’s low-cost fares and the late-evening banks, and go cabin-only where checked bags are charged separately. Watch for the final-week price jump and avoid festival peaks. Because a budget carrier sits beside three full-service airlines, the cheapest seat genuinely changes by date and time — confirm the live price in the FlightGPT search before you commit.
You depart Bangkok’s Suvarnabhumi Airport (BKK) from its single large terminal — note that Thai Vietjet uses BKK here, not Don Mueang, so double-check your airport on the ticket. You arrive at Mumbai’s Chhatrapati Shivaji Maharaj International Airport (BOM) at Terminal 2 (T2), which handles all international arrivals. If you are connecting to a domestic flight, some of those use Terminal 1, which is a separate building — allow a comfortable buffer for the transfer.
Mumbai is India’s commercial and entertainment capital — the Gateway of India, Marine Drive, Bollywood and a phenomenal food scene — and a major business destination drawing traffic from across Southeast Asia. Bangkok, in turn, is a key gateway for Indian leisure travellers and the diaspora. With non-stops under five hours and a budget option in the mix, the route is both quick and flexible on price.
Thai Vietjet’s headline fares can undercut the full-service carriers, but they typically exclude checked baggage and extras — so once you add a bag and a seat, the true cost can land close to IndiGo or a sale fare on Air India or Thai. Compare the all-in price, not just the lead fare, in the FlightGPT search, and weigh the late-night departures, which are often the cheapest.
