Flying from Delhi to Bangkok
In short
Multiple airlines fly nonstop from Indira Gandhi International Airport (DEL) in Delhi to Bangkok. Air India, IndiGo, SpiceJet and Thai Airways International land at Suvarnabhumi (BKK), while Thai AirAsia X and Thai Lion Air land at Don Mueang (DMK). The 2,948 km flight takes about 4 hours 10 minutes. Bangkok is the go-to short holiday for travellers from north India, and Delhi has more nonstop flights to Thailand than most Indian cities.
Terminal 3 and the Airport Express metro
Delhi's airport handled more than 79 million passengers in 2024–25, so allow plenty of time for check-in and security. Most international departures use Terminal 3, served by the Delhi Metro Airport Express line from New Delhi station in about 20 minutes. The rebuilt Terminal 1 reopened in 2025 for domestic flights, so check your terminal before setting off.
Night flights and what each fare includes
Air India runs its main hub at Delhi and includes a checked bag, as does Thai Airways International. IndiGo, SpiceJet, Thai AirAsia X and Thai Lion Air sell the seat and charge for checked bags, meals and seat choice. Night departures are common on the route, landing in Bangkok in the early morning.
After an overnight flight into Suvarnabhumi
Suvarnabhumi opened in September 2006 about 25 km east of the centre and has three parallel runways. The Airport Rail Link runs to Phaya Thai in about 27 minutes, where it meets the BTS Skytrain, and Makkasan connects to the MRT Blue Line. After an overnight flight, a metered taxi or Grab from arrivals is the easiest choice with bags. Coach 789 runs from the airport to Hua Hin for 294 baht.
Don Mueang lies north of the city. Its Terminal 1 handles international flights, the SRT Dark Red Line stops at the airport, and bus A1 runs to the BTS at Chatuchak for 30 baht.
Thailand's entry rules depend on nationality; see our Thailand visa page. Every foreign visitor completes the Thailand Digital Arrival Card within 72 hours before landing.
Delhi flights to Dhaka or via Bangkok
The Dhaka flights on Biman, US-Bangla and Thai Airways all leave from Suvarnabhumi (see Bangkok to Dhaka flights). Landing at Don Mueang means crossing the city and checking in again. Delhi also has its own flights: see New Delhi to Dhaka flights.
Clocks go forward 1 hour 30 minutes on landing in Thailand.

Frequently Asked Questions (FAQs)
Getting there
Flights land at both Bangkok airports: several airlines at Suvarnabhumi, and Thai AirAsia X and Thai Lion Air at Don Mueang. Schedules change by season, so check the flights for your dates in the search above.
About 4 hours 10 minutes in the air. The two airports are 2,948 km apart in a straight line; actual times vary a little by airline, aircraft and wind.
Both. Several airlines use Suvarnabhumi (BKK); two use Don Mueang (DMK). The airports are on opposite sides of the city, so check the code on your ticket.
Suvarnabhumi lies about 25 km east of central Bangkok. The Airport Rail Link runs to Phaya Thai in about 27 minutes and meets the BTS Skytrain there; Makkasan station connects to the MRT Blue Line. Metered taxis and Grab wait outside arrivals. Don Mueang is north of the city. The SRT Dark Red Line stops at the airport and runs to Krung Thep Aphiwat Central Terminal (Bang Sue), where it meets the MRT Blue Line; airport buses and metered taxis cover the rest of the city.
Yes. Biman, US-Bangla and Thai Airways fly Bangkok to Dhaka from Suvarnabhumi. If you land at Don Mueang, allow at least four hours to transfer by road and check in again. On separate tickets you clear Thai immigration and collect your bag, so you need a Thai visa. See Bangkok to Dhaka flights.
Most international flights at Indira Gandhi International use Terminal 3, but airlines can move between terminals. Check your booking for the terminal on the day.
The Airport Express metro line runs from Terminal 3 to New Delhi station, stopping at Dhaula Kuan and Shivaji Stadium. Prepaid taxis and app cabs leave from the arrivals forecourt.
General
The clock moves one hour and 30 minutes forward on landing in Thailand (Thailand is UTC+7). Neither side uses daylight saving, so the gap stays the same all year.
A passport that meets Thailand's entry rules for your nationality, plus the Thailand Digital Arrival Card, which every foreign visitor completes within 72 hours before landing. Check whether you need a visa on our Thailand visa page.
Yes; see New Delhi to Dhaka flights. Going via Bangkok is worth it if you want a few days in Thailand on the way home.
What's included
It depends on the airline. IndiGo, SpiceJet, Thai AirAsia X and Thai Lion Air are low-cost carriers whose basic fares include only a cabin bag, so add checked baggage when you book. The full-service airlines normally include a checked bag; the allowance is shown on your booking.
Stay & facilities
On the full-service airlines, request a Muslim (halal) meal when you book or at least 24 hours before departure through the airline's manage-booking page. On IndiGo, SpiceJet, Thai AirAsia X and Thai Lion Air, meals are bought online or on board; check the menu for halal options.
