Quick Answer & Key Takeaways
Main Question: What is the deadline for requesting a refund or compensation after a flight cancellation?
- US (DOT/TSA): Automatic refunds within 7 days for cancellations (domestic/international to/from US), regardless of fault. 24-hour rule allows free cancellation if booked 7+ days in advance. File DOT complaints anytime if denied.
- EU/UK: Immediate refunds; compensation claims 2-6 years (e.g., Montreal Convention 2 years, UK 6 years, Germany 3 years).
- Stats: 68% of passengers accept vouchers instead of cash refunds (2025 data); only 55% claim when eligible (AirHelp).
| Region | Refund Deadline | Compensation Deadline | Key Rule |
|---|---|---|---|
| US (DOT) | 7 days automatic | N/A (refunds only) | 24-hour rule |
| EU (EU261) | Immediate | 2-5 years by country | <14 days notice |
| UK (UK261) | Immediate | 6 years | Retained EC261 |
| Global (Montreal) | Varies | 2 years | Liability limit |
Act fast: US refunds process in 7 days, but EU claims have strict statutes of limitations.
US Flight Cancellation Refund Rules (DOT & TSA Policies)
US Department of Transportation (DOT) rules protect passengers on domestic flights and international flights to/from the US. Key: Airlines must provide refunds for significant changes or cancellations, regardless of fault--contradicting some claims that weather exempts them (per The Points Guy). "Controllable" issues (staffing, maintenance) may add hotel/meal vouchers, but refunds are mandatory.
Since October 2024, federal law mandates automatic refunds for canceled or significantly delayed flights. Airlines process in 7 days, including ancillary fees (seats, Wi-Fi). Yet, 68% opt for vouchers--often worth less than cash.
Mini Case: A United passenger's Denver-San Francisco nonstop became a Phoenix connection; United auto-refunded $872 without request.
How Long to Request a Refund for Cancelled US Flights in 2026
For 2026, request refunds immediately via airline app/site. DOT requires processing within 7 days. If denied, file a DOT complaint (no deadline, but act within 1-2 years for best results). TSA aligns: No specific timeline beyond DOT, but airlines like Delta/JetBlue offer credits/points as alternatives during FAA cuts (10% reductions at 40 hubs in 2025-2026).
EU261 & UK261 Compensation Claim Deadlines
EU Regulation 261/2004 (EU261) and UK-retained UK261 entitle passengers to refunds, care (meals/hotels), and fixed compensation (€250-€600 / £220-£520) for cancellations with <14 days notice, unless "extraordinary circumstances" (weather, strikes). Post-Brexit, UK261 mirrors EU261 but with local enforcement via CAA.
Compensation by distance:
| Distance | Compensation (EU/UK) |
|---|---|
| ≤1,500 km | €250 / £220 |
| 1,500-3,500 km | €400 / £350 |
| >3,500 km | €600 / £520 (50% if re-routed timely) |
Mini Case: Flight canceled 10 days prior due to operational issues--eligible for full €600 (Flightright).
EU261 Compensation Claim Deadline After Cancellation
Claims start from cancellation date. Montreal Convention sets 2-year global baseline, but EU countries vary. Notice <14 days = eligible; 14-7 days requires better alternative timing.
Extraordinary circumstances table:
| Circumstance | Compensation Eligible? |
|---|---|
| Weather | No |
| Staffing/Maintenance | Yes |
| Air Traffic Control | No |
| Security Risks | No |
UK 261 Flight Cancellation Compensation Time Limit & CAA Deadlines
UK261: Same amounts/notice rules (7-14 days). CAA enforces; claims up to 6 years. Submit via airline first, then CAA Alternative Dispute Resolution (no strict submission deadline, but within 6 years).
International Flight Cancellation Deadlines by Country (2026 Updates)
Montreal Convention (136 countries) limits liability claims to 2 years from arrival/disruption. Refunds immediate; compensation varies.
| Country | Compensation Deadline |
|---|---|
| Germany | 3 years |
| France | 5 years |
| UK | 6 years |
| Croatia/Netherlands/Türkiye | 2 years |
| Poland | Variable (consult local code) |
| Czech Rep. | 6 months notice to airline |
1 SDR ≈ €1.20. No confirmed 2026 extensions, but FAA-style cuts may prompt policy tweaks.

Miss Montreal Art. 31 (written protest)? Claim inadmissible. Mini Case: German cancellation Jan 2023--deadline Jan 2026. Sue in passenger's domicile, airline HQ, or carrier court (Montreal Art. 33). Consequences: Lost compensation forever.
