Airlines & nonstop vs connecting on Delhi–Bangkok
Three carriers dominate DEL–BKK nonstop: Air India, Thai Airways and IndiGo (Vietjet also operates on the city pair), totalling roughly nine to ten nonstops a day.
- Air India – among the most frequent operators; full-service into Suvarnabhumi with baggage included.
- Thai Airways – full-service flag carrier into BKK with lounges and onward Star Alliance links across Asia and the Pacific.
- IndiGo – low-cost nonstop, typically the cheapest base fare.
With this many nonstops, there's no reason to take a connection on DEL–BKK.

Flight time, distance & routing
The nonstop DEL–BKK flight time is about 4h 20m, covering roughly 2,920 km east across northern India, the Bay of Bengal and into the Gulf of Thailand. Thailand is 1.5 hours ahead of India, so the local arrival time runs later than the duration implies. Daytime and overnight departures are both available, letting you arrive in Bangkok refreshed or hit the ground running.
Best time to book & seasonal fare patterns
DEL–BKK fares are usually lowest in Thailand's green/low season — roughly May to September — when monsoon weather cools leisure demand. The dry, cool peak (November–February), the December–January holidays and the April Songkran period are the priciest times to fly.
Booking about 4–8 weeks ahead generally lands the best nonstop fares, and with several carriers competing, promotions are common. Compare live fares in the FlightGPT search rather than relying on a fixed figure.
How to get the DEL–BKK fare cheaper
- Compare Air India, Thai Airways and IndiGo on total price (fare + bags).
- Travel midweek and in the May–September low season for the cheapest seats.
- On IndiGo (and Vietjet, which uses Don Mueang), add baggage during booking.
- Set a fare alert; this competitive route sees frequent sales.
- For families needing baggage and meals, Air India or Thai Airways can beat a low-cost fare once extras are added.

Airports & terminals
Delhi (DEL): international flights, including DEL–BKK, depart from Terminal 3 at Indira Gandhi International Airport. If you're connecting from a domestic flight at Terminal 1, allow time for the inter-terminal transfer.
Bangkok: Air India, Thai Airways and IndiGo use Suvarnabhumi (BKK), the main international hub served by the Airport Rail Link into the city. If you book Vietjet, note it uses Don Mueang (DMK), the budget airport about 30 km away — check which airport your ticket lists before arranging transfers.
Baggage
Air India and Thai Airways include a generous checked allowance (typically 25–30 kg in economy by fare) plus cabin baggage. IndiGo includes cabin baggage but charges for checked bags — add the allowance during booking. See the IndiGo baggage guide and the Air India baggage page for current limits. Shoppers returning from Bangkok often hit excess-weight fees, so weigh bags before the airport.
Visa for Indian passport holders
Indian passport holders can enter Thailand visa-free for up to 60 days for tourism, short business, family visits or medical treatment (effective 13 February 2026), extendable once by 30 days at a Thai immigration office. Complete the Thailand Digital Arrival Card (TDAC) online before departure and carry proof of accommodation and a return/onward ticket. Immigration may question frequent back-to-back visa-free entries within a rolling 180-day window. Verify the current policy on Thailand's official immigration portal before you fly.
Practical travel tips
- Fill in the TDAC online before departure and save it — it speeds the e-gate at Suvarnabhumi.
- Thailand is 1.5 hours ahead of India; set your watch and adjust onward-connection buffers.
- From Suvarnabhumi, the Airport Rail Link is the cheapest way into central Bangkok; metered taxis are reliable too.
- Pick up a local SIM/eSIM at the airport for Grab and maps.
- Carry some Thai baht for street food and tuk-tuks, which often don't take cards.
