The India-Bangkok corridor has become Southeast Asia’s busiest leisure air market for Indian travelers, and 2025 numbers cemented that position. Visa-free entry, sharply expanded carrier capacity, and competitive low-cost fares have pulled record volumes through the year.
Key numbers at a glance- Why the India-Thailand corridor matters
Indian visitors to Thailand in 2025: 2.49 million
India ranked as Thailand’s 3rd largest source market after Malaysia and ChinaDirect flights Delhi and Bangkok/Week: 120+ flights weeklyIndia’s share of all international flights into Thailand: 13% weekly Flights: India-Thailand frequency: 56+ flights per weekLowest reported one-way fare from a major Indian city: ₹7,887 from Chennai to BangkokVisa-free stay for Indian travellers in Thailand: up to 60 days
Thailand’s tourism ministry recorded 32.97 million foreign arrivals in 2025, with Malaysia (4.52 million), China (4.47 million), and India (2.49 million) as the top three source markets. India’s growth in 2024 had already pushed it past pre-pandemic peaks, and the 2025 figure represented a further expansion despite a softer overall market for Thailand.
Reportedly, the growth has been concentrated on Bangkok and Phuket, with secondary demand from Indian travelers reaching Krabi, Pattaya, and Koh Samui through stopover routings. Visa-free entry, introduced as a temporary measure in November 2023 and made permanent in 2025, is the single biggest factor cited by trade publications for the surge.
Major carriers along India-Bangkok
Direct services from India to Bangkok are handled largely by Air India, Air India Express, IndiGo, Thai Airways, Thai AirAsia X, Thai Lion Air, and Vietnam Airlines (one-stop). Mumbai, Delhi, Bengaluru, Chennai, Hyderabad, Kolkata, Pune, Lucknow, Surat, and Amritsar all hold non-stop links to either Suvarnabhumi (BKK) or Don Mueang (DMK).
It’s good to know: India is now Thailand’s second-largest source of international flights after China.
Bangkok flight ticket price: What current data shows
Flights to Bangkok from major Indian cities sit in a wide fare band that varies sharply by season and booking window. Indicative one-way economy fares for off-peak travel in early 2026. Here’s an indicative table showing origin and one-way fare.Three key factors move prices most:
- Mumbai – Lowest one-way fare: ₹8,111
- Kolkata – Lowest one-way fare: ₹8,071
- Delhi – Lowest one-way fare: ₹8,411
- Bengaluru – Lowest one-way fare: ₹8,920
- Chennai – Lowest one-way fare to Bangkok: ₹7,887
- Pune – Return fare from Bangkok starting at ₹3,569 with Air India Express
- Season. Fares typically rise 50 to 80 percent during the November-February high season, the May-June Indian school break, and the Diwali window. Cheapflights data showed July as historically the cheapest month (average ₹9,670) and September as the priciest (average ₹17,516) in Delhi-Bangkok.
- Booking window. Booking 60 to 75 days ahead consistently delivers the lowest fares; tickets bought inside three weeks of departure tend to run 30 to 50 percent above shoulder fares.
- Carrier mix. Air India Express, IndiGo, Thai Lion Air, and Thai AirAsia X hold the bottom of the fare band.
Why the corridor is changing
Indian carriers have been the most aggressive expanders on the route through 2024 and 2025. For instance, IndiGo announced 56+ weekly flights to Thailand and added a second daily Mumbai-Bangkok service from July 2025, timed to feed connecting passengers into its long-haul Manchester and Amsterdam routes.
Air India Express, after its merger with AIX Connect on 1 October 2024, added Bangkok services from Amritsar, Lucknow, Pune, and Surat through 2024-25 and launched a daily Bengaluru-Bangkok service from 18 October 2025 with introductory one-way fares from ₹9,000.
The pattern is consistent where carriers are using tier-2 Indian cities to access Bangkok directly, bypassing the traditional Delhi-Mumbai trunk. Surat-Bangkok, launched in late 2024, is a good example in this case for a textile and diamond-trade corridor that previously required a connection through a metro hub.
For travelers, the practical effect is more direct services from non-metro cities and a wider spread of fare options. The flip side is that Bangkok’s two airports (Suvarnabhumi and Don Mueang) are running close to capacity during peak windows, which keeps fares firm during festival and summer-leave seasons even as overall capacity grows.
Practical points to know before booking:
- Direct flights from Indian metros to Bangkok run 4 hours to 4 hours 30 minutes. Delhi-Bangkok is the longest at about 4 hours 20 minutes, and Kolkata-Bangkok is the shortest at about 2 hours 30 minutes.
- Suvarnabhumi (BKK) handles full-service carriers; Don Mueang (DMK) is the low-cost hub for Thai Lion Air, Thai AirAsia, and AirAsia X. Inter-airport transfers take 60 to 90 minutes by road.
- Air India Express tends to publish significantly cheaper fares from Bangkok back to India than the outbound leg, particularly to Pune, Bengaluru, and Surat. Round-trip pricing usually beats two one-ways.
- Cheapest months historically: May, June, July, September. Most expensive: November, December, January.
- Bangkok is one hour and 30 minutes ahead of India; same-day arrivals are common with morning departures.
Visa requirements for Indian passport holders:
- Visa-free entry for stays up to 60 days, valid for tourism, business meetings, and medical visits. Made permanent in 2025 after a series of extensions.
- Thailand Digital Arrival Card (TDAC) is mandatory for all foreign arrivals. Travelers should complete it within three days of arrival through the official Thai immigration portal.
- Onward ticket and proof of accommodation may be requested at immigration. Random checks have increased through 2025.
Wrap Up
Thailand’s tourism authority is targeting 36.7 million foreign arrivals in 2026, and Indian arrivals are central to the plan. Indian carrier capacity will continue expanding into 2026, with carriers like Air India Express and Indigo both signaling further additions on tier-2 routes. The bottleneck is not access, as visa-free entry resolves that, but airport slots and aircraft availability at Suvarnabhumi during peak windows remains a challenge.
