Thai Airways flight delay and cancellation compensation

Up to €600 compensation per passenger. Was your Thai Airways flight delayed or cancelled, or were you denied boarding? Thai Airways is not an EU or UK airline, so EU261 and UK261 apply only to its flights departing the EU or the UK. Here is what to expect and what to do.

In short: On Thai Airways flights departing the EU you are entitled to €250–600 compensation for an arrival delay of more than 3 hours, a cancellation notified less than 14 days before departure, or involuntary denied boarding – unless the airline proves extraordinary circumstances. A Thai airline: UK261 covers its flights departing UK airports (Heathrow–Bangkok) and EU261 its flights departing EU airports. Flights from Bangkok to the UK or EU are not covered by either.

Thai Airways flight delay: when is compensation due?

If your Thai Airways flight reached its final destination at least 3 hours late (counting from when the doors opened), and the cause was within the airline's control – a technical fault, staff shortage, a delay on the previous flight, a strike by its own staff – you are entitled to compensation. It is not due if the airline proves extraordinary circumstances (weather, an air traffic control strike, an airport closure). Read the full conditions here.

Typical Thai Airways routes: London Heathrow–Bangkok, Frankfurt–Bangkok, Munich–Bangkok, Paris CDG–Bangkok, Zurich–Bangkok, Copenhagen–Bangkok.

Thai Airways flight cancellation: what are you entitled to?

If your flight is cancelled, Thai Airways must offer you a refund of the ticket price (within 7 days) or re-routing on the earliest available flight – including another airline's, if that is quicker. If you were told about the cancellation less than 14 days before departure and the re-routing offered differed significantly from the original flight, you are also entitled to compensation. More on the 14-day rule.

What to know when claiming from Thai Airways

  • Claim through the passenger-rights and contact pages on thaiairways.com. We could not open Thai's claim pages when we checked on 10 November 2026, so we do not link a specific form.
  • With one booking – for example London–Bangkok–Phuket – a missed connection counts if you reach the final destination 4 hours or more late; the distance is that of the whole journey.
  • Thai is not in a CAA-approved ADR scheme. For flights from the UK, unresolved complaints can go to the CAA's PACT.

About Thai Airways

Thai Airways International was founded in 1960 and is Thailand's flag carrier, based in Bangkok with its hub at Suvarnabhumi. It was a founding member of Star Alliance in 1997. After heavy losses it entered court-supervised rehabilitation in September 2020; the rehabilitation ended on 16 June 2025 and its shares returned to trading in August 2025.

In Europe it flies to London Heathrow, Brussels, Copenhagen, Paris, Frankfurt, Munich, Milan, Oslo, Stockholm and Zurich. In the CAA's 2025 figures Thai operated 1,457 flights at Heathrow, with 80.5% on time and 0.14% arriving 3 hours or more late.

Thai's own EU261 notice confirms that the rules apply to its flights departing an EU airport where Thai is the operating carrier. London–Bangkok is about 9,600 km, so a flight from Heathrow that arrives 4 hours or more late gives £520 per passenger (£260 for 3–4 hours).

How to claim directly from Thai Airways

  • Thai publishes an EU261 notice for flights it operates from EU airports; its claim pages blocked our check on 10 Nov 2026, so we do not link a form. Not in a CAA-listed UK ADR scheme.
  • Our complaint letter generator writes the letter for you – filled in, as a printable PDF.

We checked these claim channels on the airline's own website (10 November 2026).

Frequently asked questions

Am I entitled to compensation if my Thai Airways flight was at least 3 hours late?

Yes, if the flight departed from an EU airport and the delay was not caused by extraordinary circumstances. The amount depends on the distance: €250, €400 or €600.

How do I submit a claim to Thai Airways?

Directly through the airline's customer service form (https://www.thaiairways.com), or through our partner AirHelp, which checks the flight data and, if the airline rejects the claim, takes the case to the enforcement body or to court – for a fee of 35% only if it succeeds.

How long do I have to claim for a Thai Airways flight?

Limitation periods vary by country and are set by national law – for example 6 years in England & Wales, 5 years in Scotland and Hungary, and 3 years in Germany (from the end of the year). AirHelp typically accepts claims for flights up to 3 years old.

Thai Airways offered me a voucher instead of compensation. Do I have to accept it?

No. Under the Regulation, compensation is paid in money; the airline may only give you a voucher with your written agreement. If you want money, do not accept it.

Flew with another airline?

The Thai Airways name and trademark belong to their owner; EU261 Flight Delay is an independent information site with no connection to the airline. The content is for information only and is not legal advice. We receive a commission when a claim submitted through our partner links succeeds.
