Airlines flying Dehradun to Bangkok
No carrier flies Dehradun to Bangkok non-stop, so every itinerary routes through Delhi (DEL). IndiGo and Air India operate the short DED→DEL hop (≈ 55m), and from Delhi you join a non-stop to Bangkok on IndiGo, Air India, Thai Airways or Thai AirAsia. Self-transfer combinations are common, so leave a comfortable connection buffer at Delhi. FlightGPT compares single-ticket through-fares against cheaper split tickets so you can see the real trade-off in price versus baggage protection.
Cheapest time to fly & book
Bangkok fares from Dehradun dip in the May–June and September shoulder months and spike around Christmas-New Year, Songkran (mid-April) and Indian school holidays. Because this is a connecting long-ish trip, booking ≈ 6–10 weeks ahead typically lands the best combined fare. Mid-week departures usually beat weekends. Watch monsoon-season promotions (June–October) when Thai tourism softens and airlines discount the Delhi→Bangkok leg.
Flight duration & routing
Plan for ≈ 8–11h door-to-gate via Delhi. The DED→DEL leg is ≈ 55m, then a layover of 1.5–4h, then a ≈ 4–4.5h non-stop Delhi→Bangkok. Total time swings on your Delhi layover, so an early DED departure that connects to a daytime Bangkok flight is the smoothest. Arrival is at Suvarnabhumi (BKK); some low-cost Delhi flights instead use Don Muang (DMK), so check your onward airport.
Baggage & fares
The domestic DED→DEL leg on IndiGo gives ≈ 15 kg checked; the international Delhi→Bangkok leg typically allows ≈ 25–30 kg on full-service and a paid allowance on low-cost carriers. On self-transfer tickets you may need to re-check bags at Delhi, so confirm the through-baggage policy. Indicative fares are live on FlightGPT as of May 2026; a single through-ticket often costs more but protects you if the first leg is delayed.
Airports & terminals
Dehradun's Jolly Grant (DED) has a single passenger terminal ≈ 25 km from the city. At Delhi you usually arrive at T3 and depart Bangkok flights from T3 as well, which keeps connections inside one building — confirm on your ticket. Bangkok's main gateway is Suvarnabhumi (BKK), ≈ 30 km east of the city; budget Delhi flights may land at Don Muang (DMK) in the north. Allow extra time if you must change Bangkok airports.
Visa & entry for Indians
Indians travelling to Thailand can, as of 2026, use Visa-on-Arrival (≈ THB 2,000) plus the online TDAC arrival card — but Thai rules have shifted recently, so confirm current requirements before booking. Carry a passport valid ≥ 6 months, a return ticket and proof of funds. Some travellers prefer an e-visa to avoid airport queues. See /visas for the latest Thailand entry guidance and document checklist.
