Flight delays and cancellations are frustrating at the best of times, but knowing your rights turns a stressful experience into a manageable one. The compensation you are owed depends on which country the flight departs from, which airline is operating it, and the length of the delay. Here is what every traveller on Thai and international routes needs to know.
Thai Domestic Flights: CAAT Rules
The Civil Aviation Authority of Thailand (CAAT) sets the minimum standards for domestic flights operated by Thai carriers. Under the Ministry of Transport’s passenger rights notification, airlines must:
- Provide meals and refreshments when a delay reaches 2 hours or more
- Offer accommodation if an overnight delay occurs due to the airline’s own fault (not weather or air traffic control)
- Notify passengers as early as possible and provide status updates throughout
- Arrange alternative transport if the airline cannot get you to your destination within a reasonable time
Compensation payments for domestic Thai routes are not standardised in the same way as EU law. Your primary remedies are a full refund if you choose not to travel, or rebooking on the next available flight. In practice, Thai carriers including Thai Airways, Bangkok Airways, and Nok Air handle most claims through their own customer service processes - keep receipts for any out-of-pocket expenses (meals, hotels, transport) and submit them directly to the airline within 30 days of the incident.
International Flights: When EU261/2004 Applies

EU Regulation 261/2004 is the most powerful passenger protection law in the world, and it applies to flights departing from any EU or EEA airport regardless of the airline, plus flights arriving into an EU airport operated by an EU-based carrier.
What this means for Thailand travellers:
- Flying London, Paris, Amsterdam, Frankfurt, or any EU/EEA airport to Bangkok? EU261 applies - even on Thai Airways or Emirates.
- Flying Bangkok to Amsterdam on KLM? EU261 applies (EU carrier, EU destination).
- Flying Bangkok to London on Thai Airways? EU261 does not apply - non-EU carrier departing from outside the EU.
EU261 Compensation Thresholds
Compensation is calculated by flight distance and applies when the delay at your final destination exceeds 3 hours and the cause was within the airline’s control (not extraordinary circumstances like severe weather or air traffic control strikes).
| Flight distance | Delay of 3+ hours | Compensation |
|---|---|---|
| Up to 1,500 km | 3+ hours | €250 per passenger |
| 1,500–3,500 km | 3+ hours | €400 per passenger |
| Over 3,500 km | 3+ hours | €300 (delay 3–4 hours) or €600 (delay 4+ hours) |
Bangkok is over 9,000 km from most European airports, so long-haul compensation is typically €600 per person for a 4-hour delay that is within the airline’s control.
Right of Care Under EU261
Regardless of compensation eligibility, EU261 also gives you the right to meals, refreshments, and communication (phone calls or email) when a delay reaches 2 hours. For overnight delays caused by the airline, they must provide hotel accommodation and transfers. Always ask at the gate - airlines are legally required to offer this.
UK Flights After Brexit
The UK retained EU261 in domestic law as UK Regulation 261/2004 when it left the EU. The compensation thresholds and eligibility rules are identical. Flights departing any UK airport - including Heathrow, Gatwick, and Manchester - are covered, as are flights arriving into UK airports on UK-registered carriers. For Bangkok–London routes, Heathrow departures are fully covered; Bangkok arrivals on British Airways and Virgin Atlantic are also covered.
How to File a Claim
Step 1 - Document everything. Screenshot your boarding pass, the airline’s delay notification, and the actual departure and arrival times. Note the reason given by the airline.
Step 2 - Calculate your eligibility. Use the distance and delay thresholds above. If your delay was over 3 hours at the final destination and departed from an EU or UK airport, you almost certainly have a valid claim.
Step 3 - Contact the airline directly first. Submit a written claim to the airline’s customer service team referencing EU Regulation 261/2004. Include your flight number, date, booking reference, and bank details. Airlines have 14 days to respond.
Step 4 - Escalate if needed. If the airline rejects your claim or doesn’t respond, you can escalate to the relevant National Enforcement Body (CAA in the UK, the national civil aviation authority in the EU country of departure). In the UK, you can also take the case to an approved alternative dispute resolution scheme such as CEDR or Aviation ADR.
Step 5 - Use a claims service for complex cases. If dealing with airline bureaucracy sounds daunting, no-win no-fee compensation services will handle the process for you in exchange for a percentage of the payout - typically 25–35%. This is a reasonable trade-off for multi-leg or multi-passenger claims.
Practical Tips

- Keep all receipts. Meals, hotel nights, and transport you paid for out of pocket during a covered delay are reimbursable under right-of-care rules, separate from any cash compensation.
- Don’t accept vouchers without reading the terms. Airlines sometimes offer travel vouchers as settlement - these may waive your right to the full cash amount. You are entitled to cash compensation under EU261.
- Claims can be filed up to 6 years after the flight in the UK and most EU countries. Do not assume it is too late.
- Missing a connection counts. If a delay caused you to miss an onward connecting flight booked under the same reservation, the total journey delay determines your compensation - not just the first leg.
