For air passengers worldwide, missing deadlines is the top reason claims fail--over 50% of rejections stem from expired time limits, per airline reports. Here's a scannable summary:
| Region/Regulation | Time Limit for Claims | Key Notes | Success Rate (Timely Claims) |

| US DOT | 1 year for refunds; up to 3 years for some disputes | Strict enforcement; $100M+ refunds in 2025 | 60% |
| UK (Post-Brexit) | 6 years | Applies to delays >3 hours; mirrors EU but extended | 75% |
| Montreal Convention | 2 years (delays/baggage) | International standard; overrides some airline policies | 65% |

Key Takeaways: Essential Time Limits at a Glance
- EU261: 2 years in Ireland/France; up to 6 years in Italy/Portugal--check your flight's departure country.
- US DOT: 1-year refund deadline for delays >3 hours; 3 years for disability/ancillary claims.
- UK: Generous 6-year window under Limitation Act 1980--ideal for older claims.
- Montreal Convention: Strict 2-year global cap for international flights, including baggage delays.
- Common Pitfalls: Long stopovers or connecting flights can confuse jurisdiction--file under the longest limit. Over 40% of claims fail due to paperwork delays.
- Pro Tip: 20-30% of "expired" rejections are overturned on appeal.
Understanding Time Limits in Delayed Flight Disputes
Time limits, or statutes of limitations, are legal deadlines for filing claims. Missing them creates time bars, where courts dismiss cases regardless of merit. Airlines exploit this--rejecting 50%+ of late claims citing internal policies shorter than law.
Mini Case Study: Passenger A flew Ryanair (EU) in 2023, claimed in 2026 (3 years later). Rejected as "expired" under airline's 2-year policy. Court ruled Ireland's 2-year limit applied--but extension granted due to airline's misleading info, awarding €400.
These limits protect airlines from endless liability but safeguard passengers if filed promptly.
EU261 Time Limits for Delayed Flight Claims
EU Regulation 261/2004 mandates compensation for delays >3 hours. Time limits vary by national law:
| Country | Limit | Payout Example |
|---|---|---|
| France/Ireland | 2 years | €600 (long-haul) |
| Netherlands/Germany | 3 years | €600 |
| Italy/Portugal | 6 years | €600 |
EU Commission data: €500M+ paid yearly; 70% success if timely. For long stopovers, use departure country's limit.
US DOT Delayed Flight Refund Deadlines
US rules (14 CFR Part 259) require refunds within 1 year for controllable delays >3 hours. DOT's 2025 enforcement yielded $100M+ refunds. Some claims (e.g., tarmac delays) extend to 3 years under statutes. Airlines like Delta cite 1-year policies, but DOT overrides.
UK 6-Year Limitation Period for Flight Delay Claims
Post-Brexit, UK retains EU261-like rights under Air Passenger Rights. Limitation Act 1980 sets 6 years from delay date--longer than EU average. Court Example: Stokes v EasyJet (2024)--claim filed 5.5 years later upheld, €520 awarded. Pre-Brexit EU flights often get 6 years too.
Global Variations: Montreal Convention, IATA Rules, and Baggage Delays
Montreal Convention (1999): 2-year limit for international delay/baggage claims--universal, trumping airline policies. Applies to 130+ countries; high volume (millions yearly).
IATA Rules: Recommend 21 days for complaints, 1-2 years claims--but non-binding. Contradiction: Airlines reject via IATA short limits; courts enforce law.
Baggage delays: Strictly 2 years under Montreal.
EU261 vs US DOT vs UK: Time Limit Comparison Table
| Aspect | EU261 | US DOT | UK |
|---|---|---|---|
| Deadline | 2-6 years | 1-3 years | 6 years |
| Payout | €250-€600 | Refund (full ticket) | €250-€600 |
| Pros | Generous, country variations | Strict airline enforcement | Longest window |
| Cons | Varies; airline pushback | Refunds only (no flat comp) | Brexit confusion |
| Eligibility | >3hr delay, EU airport | Controllable US flights | >3hr, broad |
Airline policies often shorter (e.g., 1 year)--law prevails.
What If Your Claim is Expired? How to Dispute Missed Deadlines
20-30% of appeals succeed post-deadline. Strategies: Argue airline misled you (estoppel), or use GDPR for data access proving delay.
Mini Case: EU passenger missed 2-year limit; GDPR complaint forced airline records, court extended via "special circumstances," €600 won.
Strategies for Extending Time Limits or Filing Late
- Request Extension: Cite airline delays in responding (COT3-like agreements).

- GDPR Leverage: Demand records within 1 month; builds late-claim case.
- ADR/NAC: UK/EU free mediation ignores strict airline limits.
Airline policies (1-2 years) vs legal extensions: Courts favor passengers 25% of time.
