Did an airline reject your flight claim for being late?
Airlines often deny compensation by claiming you missed an internal deadline. They cite terms buried in their booking conditions. Don't take their word for it. The law says otherwise.
In many cases, legal deadlines run for years, not weeks. Carriers hope you walk away after the first rejection. Many travelers do. That is a costly mistake.
Company Deadlines vs. Real Legal Limits
Airlines love inventing their own deadlines. You might see a clause requiring claims within 30 days, 60 days, or six months of travel.
Turns out, private booking conditions cannot override statutory consumer rights. The European Court of Justice settled this principle years ago in the Cuadrench More ruling. When you fly on an itinerary covered by European passenger rules, national limitation laws dictate your time limit, not the airline's contract.
If you flew from London, national law governs your claim window. If you flew from Frankfurt, German law applies. The differences between countries are substantial, as shown below:
| Country of Departure or Carrier Base | Legal Time Limit | When the Clock Starts |
|---|---|---|
| United Kingdom | 6 years (5 in Scotland) | Date of the flight disruption |
| Germany | 3 years | End of the calendar year of the flight |
| France | 5 years | Date of the scheduled arrival |
| Spain | 5 years | Date of the flight disruption |
| Italy | 2 years | Date of the flight disruption |
| Ireland | 6 years | Date of the flight disruption |
German law offers a generous grace period. If your flight was delayed in March 2023, your three-year clock did not start until December 31, 2023. You have until the end of 2026 to file. An airline agent quoting a 90-day window is simply wrong.
How Time Limits Work on US Flights
US flights follow a completely different framework.
Federal law does not require cash compensation for routine delays on domestic flights. You cannot demand a fixed payout like you can under European regulations.
You do, however, have strong refund rights under DOT ticket refund rules when delays become significant. If the airline significantly alters your schedule and you refuse the new flights, you are owed a prompt cash refund. The Department of Transportation treats delays of three hours or more on domestic itineraries, and six hours or more on international routes, as significant disruptions.
Airlines must pay cash refunds quickly. Credit card refunds take seven business days. Cash or check payments take twenty days.
Thing is, filing a complaint about an unpaid refund with the DOT does not carry a rigid 30-day statute. While you should dispute delayed refunds promptly with your credit card issuer to protect chargeback deadlines, DOT enforcement complaints remain viable as long as the carrier holds your money improperly.
How to Push Back Against an Expired Claim Denial
When an airline shuts down your compensation request, you need to appeal with concrete statutory references. Follow these steps to reopen your case:
- Identify the governing jurisdiction. Pinpoint the country where your flight departed. If you flew on an EU or UK carrier into Europe, the arrival country or airline headquarters can also establish jurisdiction.
- Pull your original booking records. Locate your electronic ticket, booking reference code, original itinerary, and any delay notices the airline sent via text or email.
- Draft a direct written rebuttal. State clearly that the carrier's internal terms cannot shorten the statutory limitation period established by national law. Quote the specific statute, whether that is the UK Limitation Act 1980 or the German Civil Code.
- Set a firm response deadline. Give the airline fourteen business days to review your claim and issue payment.
- Escalate to an approved dispute body. If the airline ignores your letter or repeats its denial, file your complaint with an official Alternative Dispute Resolution entity or the national aviation regulator.
I've seen carriers try to push a 30-day window on people who had clear six-year statutory rights under UK law, and honestly, seeing customer service reps paste the exact same generic cutoff paragraph over and over is infuriating, but it happens all the time.
Keep pushing.
Hard Deadlines You Cannot Avoid
Not every deadline can be challenged. Some cutoffs are carved into international treaties and leave zero wiggle room for appeals.
The Montreal Convention governs international flights between participating nations. If you are seeking compensation for actual monetary damages caused by a delay, such as emergency hotel expenses or ruined non-refundable reservations, Article 35 sets an absolute two-year deadline. The clock starts on the date the aircraft arrived or was scheduled to arrive.
Missing that two-year mark extinguishes your right to sue. Courts have no power to extend Montreal Convention timeframes, even if you suffered an illness or the carrier dragged out email correspondence.
To be honest, confusing Montreal Convention rules with EU261 or UK261 is where many passengers slip up. A fixed lump-sum delay claim under European rules follows local civil law, often giving you three to six years. But claiming extra out-of-pocket damages on an international ticket expires after exactly twenty-four months.
What Evidence Overturns a Time-Barred Denial
When you contact an ombudsman or small claims arbitrator, paperwork wins the argument. The carrier will claim you forfeited your rights through inaction.
Prepare these key documents to dismantle their defense:
- Time-stamped disruption proof, including airport departure board photos, flight tracker logs, or carrier text messages.
- Your original ticket purchase confirmation showing flight numbers, passenger names, and travel dates.
- Copies of every written communication between you and the airline, especially their initial rejection message citing the alleged expiration.
- A written reference to the applicable national statute of limitations confirming your claim was submitted within the legal window.
Check your flight date right now. If your disrupted flight happened within the legal windows outlined above, file your appeal today and hold the airline accountable.
