Three carriers fly Bangkok (BKK) to Delhi (DEL) non-stop: Air India, IndiGo and Thai Airways. Together they operate roughly 8–10 departures a day, all from Suvarnabhumi (BKK). IndiGo and Air India fly mostly A320-family narrowbodies, while Air India and Thai Airways rotate widebodies (A330 / B787) onto some frequencies. SpiceJet has dipped in and out of this route in the past, so treat it as intermittent rather than a dependable daily option — always confirm the live operator when you book.
The route covers about 2,947 km and non-stop flights take roughly 4h 40m gate to gate westbound, tracking across the Bay of Bengal and central India. The return to Bangkok is usually a touch longer against prevailing winds. With several departures spread across the day — including useful late-evening services that land in Delhi after midnight — you can match the flight to your onward plans rather than the other way round.
Fares climb around the October–January high season, Thai festival periods, Diwali and the Christmas–New Year peak, and ease through the quieter monsoon months. On a route with this much capacity, booking 3–6 weeks ahead is usually enough, though festival dates reward earlier planning. Mid-week departures and the late-night banks tend to be cheapest. Compare Air India, IndiGo and Thai Airways together in the FlightGPT search with flexible dates to catch the lowest fare.
To save honestly: shift to mid-week travel, consider the late-evening departures that often price below the daytime ones, and travel cabin-only on the low-cost fares to skip checked-bag charges. Avoid the final-week price jump and the festival peaks. Because a full-service carrier like Thai Airways and low-cost IndiGo sit side by side here, the cheapest option genuinely shifts by date — so always confirm the live price in the FlightGPT search before booking.
You depart Bangkok’s Suvarnabhumi Airport (BKK), which handles all three carriers from its single large passenger terminal; allow time, as it is a big, busy hub. You arrive at Delhi’s Indira Gandhi International Airport (DEL) at Terminal 3 (T3), where all international flights land. T3 is well connected to the city by the Airport Express Metro and prepaid taxis. If you are connecting onward to a domestic flight, note that some domestic services use Delhi’s Terminal 1 or 2, so leave a comfortable buffer.
Bangkok is a major gateway for Indian travellers returning home and for tourists pairing Thailand with a North India trip, while Delhi opens up the capital region, the Taj Mahal at Agra, and the wider Golden Triangle. The route also carries steady business and trade traffic. With non-stops under five hours and several daily choices, it is one of the easier long-ish hops between the two countries.
Because Air India and Thai Airways sometimes swap a widebody onto this route while IndiGo stays narrowbody, the comfort and baggage rules can differ flight to flight on the same day. If a roomier widebody or a higher checked allowance matters to you, check the aircraft and fare inclusions in the FlightGPT search rather than assuming they are identical — and weigh the late-night fares, which are frequently the cheapest.
