Your stomach drops. Your plans fall apart. And the airline staff? Nowhere to be found.

Here’s the thing most travelers don’t know: you may be legally entitled to hundreds of dollars in compensation — and the airline is counting on you not knowing that.

This guide breaks down exactly what to do when your flight is cancelled or delayed in 2026, how to protect yourself at the airport, and how to claim the money you’re owed without a lawyer or any legal expertise.

1. What Are Your Rights When a Flight Is Delayed or Cancelled?

Most travelers have no idea that international aviation law gives them serious financial protections. The most important one is EU Regulation EC 261/2004 — and it applies much more broadly than you’d think.

This law covers you if:

• Your flight departed from any EU airport (regardless of which airline)
• Your flight arrived at an EU airport on an EU-based airline (like Lufthansa, Ryanair, Air France, etc.)
• Your flight was delayed by 3 hours or more at arrival
• Your flight was cancelled with less than 14 days’ notice
• You were denied boarding due to overbooking

So even if you’re flying from Bangkok to London on British Airways, or from Dubai to Paris on Air France — you’re covered.

UK law (UK261) mirrors EU rules post-Brexit. US DOT rules also require compensation for denied boarding due to overbooking on US flights.

The key exception: if the delay or cancellation was caused by “extraordinary circumstances” like severe weather, air traffic control strikes, or political unrest — the airline may not be required to pay. But this exception is often misused by airlines to avoid paying legitimate claims.

2. What to Do Immediately at the Airport

When your flight gets cancelled or delayed, the next 30 minutes matter. Here’s what to do right away:

Document everything. Take a photo of the departure board showing your flight status. Screenshot the airline app. Save any SMS or email notifications you receive. This is your evidence.

Go to the airline desk — but know your rights first. The airline must provide you with a written notice of your rights. If they don’t offer it, ask for it. They are legally required to give it to you.

Ask for meals and accommodation if the delay is long enough. Under EU law, if your delay is 2+ hours, the airline must provide food and drink vouchers. If it’s overnight, they must provide a hotel and transport. Don’t pay out of pocket if you can avoid it — but if you do, keep every receipt.

Don’t accept a voucher without reading it carefully. Airlines sometimes offer travel vouchers as compensation. If you sign anything accepting a voucher, you may be giving up your right to cash compensation. Read before you sign.

Get the reason for the delay in writing. Ask the airline staff to write down the official reason for the delay or cancellation. This becomes important when you file your claim.

Keep your boarding pass. Don’t throw it away. This is your proof that you were actually on the flight.

3. How to Claim Flight Delay Compensation — Step by Step

You have two options for claiming: doing it yourself, or using a specialist service.

Doing it yourself means contacting the airline directly, submitting a formal complaint, and potentially dealing with months of back-and-forth. Airlines are notoriously slow and dismissive when handling direct claims. Many travelers give up.

Using a specialist service like AirHelp or Compensair means they handle everything — the legal paperwork, airline negotiations, and if necessary, court action — on your behalf. They only take a commission if they win. If they lose, you pay nothing.

Here’s the step-by-step process using a specialist service:

Step 1: Check if your flight is eligible. Both AirHelp and Compensair have free eligibility checkers on their websites. Enter your flight details and they’ll tell you immediately if you have a valid claim.

Step 2: Submit your claim. Fill in the online form with your flight details, booking confirmation, and personal information. This takes about 5 minutes.

Step 3: Let them work. The service contacts the airline, handles all communication, and escalates to legal action if needed. You don’t have to do anything.

Step 4: Get paid. If the claim is successful, the money is transferred to your bank account minus the service’s commission. Typical compensation is €250–€600 per passenger.

4. AirHelp vs Compensair: Which Service Should You Use?

Both AirHelp and Compensair are legitimate, trusted services used by millions of travelers. But they work slightly differently. Here’s how they compare:

5. Which One Should You Use?

Choose AirHelp if:

• You want the most established service with the largest track record
• Your claim involves a complex route or multiple airlines
• You want an app to track your claim status in real time
• You’re claiming for a US or Brazilian flight (Compensair doesn’t cover these)
• You want 24/7 customer support

Start your AirHelp claim here →

Choose Compensair if:

• You want a slightly lower commission rate (which means more money in your pocket)
• Your flight was within EU, UK, or US routes
• You want a straightforward, no-fuss process
• You’re happy without a mobile app

Start your Compensair claim here →

Honestly? If your flight qualifies, submit to both and see which one responds faster. There’s no rule that says you can only use one service — just don’t accept duplicate payouts.

6. How Much Compensation Can You Get?

Under EU Regulation EC 261/2004, compensation is calculated based on flight distance:

Short flights (under 1,500 km): €250 per passenger Examples: London to Paris, Dubai to Muscat, Bangkok to Kuala Lumpur

Medium flights (1,500 km – 3,500 km): €400 per passenger Examples: London to Cairo, Frankfurt to Dubai, Bangkok to Delhi

Long flights (over 3,500 km): €600 per passenger Examples: London to New York, Dubai to Bangkok, Dhaka to London

These amounts are per passenger. So if you’re travelling with 4 people and your long-haul flight was cancelled — that’s potentially €2,400 your family is owed.

The compensation amount can be reduced by 50% if the airline offers you an alternative flight that gets you to your destination within a certain time window. But you’re still entitled to something.

7. Common Mistakes That Kill Your Claim

Throwing away your boarding pass. This is your number one piece of evidence. Keep it — digital or physical — until your claim is resolved.

Accepting vouchers without reading the terms. Some vouchers include a clause waiving your right to further compensation. Read every word before signing anything.

Waiting too long. Most countries allow 3–6 years to file a claim, but the longer you wait, the harder it is to gather evidence. File as soon as possible.

Blaming the wrong thing. If you tell the claim service “the weather was bad” without verifying this, you may accidentally undermine your own claim. Let the professionals assess the cause.

Not claiming for connecting flights. If a delay caused you to miss a connecting flight and arrive at your final destination 3+ hours late, you may still be entitled to compensation — even if the first flight was only delayed by 1 hour.

Giving up after one rejection. Airlines reject a huge percentage of first-time claims hoping travelers will give up. Services like AirHelp and Compensair know this and escalate accordingly. Don’t accept the first “no.”

8. FAQ

Q: My flight was delayed 2 hours — can I still claim? A: Under EU law, compensation is triggered at 3 hours of arrival delay, not departure. If your flight left 2 hours late but landed only 2 hours 45 minutes late, you likely don’t qualify. But check with AirHelp or Compensair — they’ll tell you for free.

Q: How far back can I claim? A: This varies by country, but generally 3–6 years. UK allows 6 years, most EU countries allow 3 years, the US allows 2 years for denied boarding claims. Don’t assume it’s too late — check your specific route.

Q: The airline said the delay was due to bad weather. Can I still claim? A: Weather is a common excuse airlines use. However, if the weather affected another flight and the delay cascaded onto yours — that may not qualify as “extraordinary circumstances.” Let a specialist assess it rather than accepting the airline’s word.

Q: Do I need a lawyer to claim? A: No. Services like AirHelp and Compensair handle everything including legal escalation at no upfront cost. You only pay if they win.

Q: What if I booked through a travel agency, not directly with the airline? A: Doesn’t matter. Your claim is against the operating airline, not the booking platform. You are still eligible.

Q: Can I claim if the airline offered me a replacement flight? A: Yes, in many cases. If the replacement flight arrived at your destination 3+ hours later than originally planned, you may still be entitled to compensation — even if you accepted the rebooking.

Q: Is this only for European flights? A: EU law (EC 261/2004) applies to all flights departing from any EU airport, and all flights arriving into the EU on EU-based airlines. UK law mirrors this. US DOT rules apply to denied boarding on US flights. Many non-EU countries are developing similar laws too.

Final Thoughts: Don’t Let the Airline Keep Your Money

Flight delays and cancellations are stressful enough without the airline profiting from your ignorance. Millions of dollars in legitimate compensation goes unclaimed every year simply because travelers don’t know their rights or don’t know how to file.

You have nothing to lose. Both AirHelp and Compensair work on a no-win, no-fee basis — if they don’t recover your compensation, you pay nothing.

If your flight has ever been delayed, cancelled, or overbooked — check your eligibility right now. It takes 5 minutes and the average payout is €350.
