Thai Airways: booking check, check-in and Bangkok rules

How to look up a booking on Thai Airways

1. 1Go to My trips on thaiairways.com; the India version of the site sits under /en-in/.
2. 2Enter the last name exactly as it was booked.
3. 3Add the booking reference, which THAI also calls the reservation code, or the electronic ticket number (ETK).
4. 4From 24 hours before departure the same details open mobile check-in, where a frequent flyer number, passport or boarding-pass barcode can also identify you.
5. 5Compare every name with the passport. THAI does not permit name changes once a booking is completed, so an error means a new booking.

THAI’s 72-hour pay-later rule versus a flight reservation

THAI’s reservation and ticketing terms for India list a pay-later option: “Contact at THAI ticket office in the country where the journey commences within 72 hours after booking has been made”, with Thailand excluded. No fee is stated, and reservations must be made at least six hours before departure. A separate 24-hour hold under THAI’s US customer service plan applies only to the US.

Seventy-two hours, plus a visit to a THAI office to pay, rarely line up with a visa appointment. A flight reservation on a THAI routing does the documenting part: held in your name for the planned dates, ordered for the day you submit. Check the spelling of every name the moment it arrives, because THAI does not allow name changes on a completed booking, and a misspelt name means starting again.

Checking in for THAI flights from Indian airports

THAI’s India pages say mobile check-in runs from 24 hours to 1 hour before departure; kiosks at Suvarnabhumi open 48 hours ahead and close 90 minutes before take-off. Counter times disagree between pages: the India check-in page says international counters close 50 minutes before departure, the boarding-pass page says 60. Work to 60 minutes, with gates closing 10 minutes before departure.

Printing your own boarding pass outside Thailand is allowed only “where the Advance Passenger Information is not required and your proper travel document provided”. THAI does not say whether Indian departures qualify, so plan on collecting the pass at the counter in Delhi or Mumbai. Passengers with special care needs, including wheelchair users, children travelling alone and anyone carrying sports equipment, pets or excess baggage, cannot check in online.

• From 1 April 2025, Economy Standard (K, S, V) and Saver (W, L) fares carry 23 kg instead of 25 kg.
• Tickets issued from 25 November 2025 for travel from 2 March 2026 on Asia–Pacific routes, India–Bangkok included, use the piece concept.
• Power banks may not be used on board THAI flights from 15 March 2025.

Entering Thailand or connecting in Bangkok

Indian ordinary passport holders are visa-exempt in Thailand for 30 days, which the Royal Thai Embassy in New Delhi says “remains effective from 15 September 2026 until further announcement”. Visitors using the exemption are expected to show travel out of Thailand within those 30 days, and every non-Thai arrival must complete the Thailand Digital Arrival Card within three days before landing. Thailand also issues a TS transit visa, applied for online at thaievisa.go.th.

For a THAI connection from India to Japan, Australia or elsewhere, a formal airside-transit rule for Indians is not confirmed, but the exemption means you could enter if you had to. Switching between Suvarnabhumi and Don Mueang is always an entry into Thailand, as is a self-transfer on two bookings. Keep the whole journey on one THAI booking, and make sure the final destination’s visa is in place, because Bangkok does not cover it.

THAI’s India network in 2026

THAI’s India directory lists Ahmedabad, Bengaluru, Chennai, Delhi, Gaya, Hyderabad, Kochi, Kolkata and Mumbai. It is a destination list rather than a timetable, so frequencies, seasonal services such as Gaya, and whether each city is non-stop are not confirmed. The first Airbus A321neo entered service in January 2026 and was scheduled onto Delhi (TG331/TG332) between late January and late March 2026.

THAI cut 15 flights on 1 October 2026 and nine on 2 October “to align flight operations with its operational capacity”, including Delhi (TG315/316) and Mumbai (TG317/318) services, and resumed its full schedule on 3 October. Its Winter 2026/27 plan adds Da Nang and Xiamen but no new Indian city.
