Six hours stuck at Barcelona airport. Flight delayed due to “operational issues.” Airline offered meal vouchers and vague apologies.

I’d heard about EU261 compensation—up to €600 for long delays on European flights. But dealing with airlines is notoriously frustrating. Enter flight compensation apps: they handle the claim, you get money minus their cut.

I tested three services across multiple delayed flights. Here’s the honest assessment of whether they’re worth using.

Quick Comparison

Service	Success Rate (My Experience)	Timeline	Fee	Best For
AirHelp	2/3 claims successful	3-6 months	35%	Ease of use
Flightright	1/2 claims successful	4-8 months	25-35%	Lower fees
ClaimCompass	1/1 claim successful	5 months	35%	EU flights specifically

Bottom line: They work, but slowly. Expect months, not weeks. DIY claims work too if you have patience.

How Flight Compensation Works

EU261 (European Flights)

If your flight is delayed 3+ hours or cancelled, you may be entitled to:

• €250 for flights under 1,500 km
• €400 for flights 1,500-3,500 km
• €600 for flights over 3,500 km

Applies when: Flight departs from EU airport OR arrives at EU airport on EU airline.

Doesn’t apply when: “Extraordinary circumstances” (weather, air traffic control strikes, security). Airlines love claiming extraordinary circumstances.

US Flights

No equivalent regulation. You’re mostly at airline discretion. DOT rules require refunds for cancellations but don’t mandate compensation for delays.

The App Model

Compensation apps work on contingency:

1. You submit your flight details
2. They check if you’re eligible
3. If yes, they pursue the claim with the airline
4. If successful, you get compensation minus their fee (typically 25-35%)
5. If unsuccessful, you pay nothing

The value proposition: they handle the bureaucracy and legal follow-up. You wait and maybe get money.

My Claims Experience

Claim 1: Barcelona Delay (AirHelp)

Flight: BCN → JFK, 6-hour delay Airline: American Airlines Compensation owed: €600 Outcome: Successful after 4 months Received: €390 (after 35% fee)

The easiest experience. Submitted claim, uploaded boarding pass, waited. No action required from me. Payment arrived via PayPal.

Claim 2: Paris Cancellation (AirHelp)

Flight: CDG → SFO, cancelled Airline: Air France Compensation owed: €600 Outcome: Successful after 6 months Received: €390 (after 35% fee)

Air France fought the claim. AirHelp escalated. Eventually settled. I received updates but didn’t have to do anything.

Claim 3: Munich Delay (AirHelp)

Flight: MUC → LAX, 4-hour delay Airline: Lufthansa Compensation owed: €600 Outcome: Unsuccessful Reason: Lufthansa claimed “extraordinary circumstances” (crew scheduling issue). AirHelp disputed but lost.

No fee charged since unsuccessful. But also no compensation.

Claim 4: Amsterdam Delay (Flightright)

Flight: AMS → London, 3.5-hour delay Airline: KLM Compensation owed: €250 Outcome: Successful after 8 months Received: €175 (after 30% fee)

Slower than AirHelp, with less communication. But eventually worked.

Claim 5: Rome Cancellation (Flightright)

Flight: FCO → London, cancelled Airline: EasyJet Compensation owed: €250 Outcome: Still pending after 5 months

Submitted in August, still “in progress” in January. Flightright says they’re pursuing it. We’ll see.

Claim 6: Lisbon Delay (ClaimCompass)

Flight: LIS → NYC, 5-hour delay Airline: TAP Compensation owed: €600 Outcome: Successful after 5 months Received: €390 (after 35% fee)

Similar process to AirHelp. Worked without issues.

App-by-App Assessment

AirHelp

Pros:

• Largest service, most airline relationships
• Clean app and web interface
• Good communication during claims
• Flight checking is instant

Cons:

• 35% fee is on the higher end
• Aggressive upselling (premium memberships, etc.)
• They gave up on my Lufthansa claim relatively quickly

My take: The default choice. Works well enough, but the fee stings on large claims.

Flightright

Pros:

• Fees can be lower (25-35% depending on claim)
• German company, well-established in EU claims
• Willing to go to court if needed

Cons:

• Slower process than competitors
• Less polished app experience
• Communication is minimal

My take: Use if you’re patient and want potentially lower fees. Not for people who want regular updates.

ClaimCompass

Pros:

• Straightforward process
• Good success rate in my (limited) experience
• Clear fee structure

Cons:

• Smaller operation than AirHelp
• Less name recognition
• Limited to EU261 claims

My take: A solid alternative, particularly for EU flights. Worth checking their eligibility calculator.

DIY vs. Apps

You can file claims directly with airlines for free. Why use apps?

DIY works when:

• Airline accepts your claim quickly (rare)
• You have time and patience to follow up
• The compensation is small and not worth losing 35%

Apps work when:

• Airline ignores or rejects your claim (common)
• You don’t want to deal with bureaucracy
• You’re willing to trade money for convenience
• The claim might require legal action

My honest assessment: Airlines count on people giving up. If you submit a direct claim and they reject it (or just don’t respond for months), apps provide persistence you might not have.

For a €600 claim, losing €210 to fees still nets you €390 you probably wouldn’t get otherwise. The math usually works in favor of apps unless you’re willing to really fight.

When Apps Don’t Help

Extraordinary Circumstances

If the delay was caused by weather, security threats, or air traffic control issues, compensation isn’t owed. Apps can’t change this.

Airlines do abuse the “extraordinary circumstances” claim. Apps will challenge dubious excuses. But sometimes the airline is legitimately exempt.

Non-EU Flights

For US domestic flights or flights that don’t touch the EU, apps have limited utility. US compensation rights are minimal, and apps can’t create entitlements that don’t exist.

Small Claims

A €250 claim minus 35% fee leaves €162.50. If you’re comfortable filing yourself, the effort might be worth keeping the full amount.

Time Urgency

Claims take months. If you need money quickly, apps won’t help. They’re playing the long game with airlines.

Tips for Maximizing Compensation

Document Everything

• Keep boarding passes
• Screenshot delay times from airport boards
• Save airline communications
• Note what the airline offered (meals, hotels, rebooking)

Check Eligibility Immediately

Apps offer free eligibility checks. Know if your flight qualifies before investing mental energy.

File Promptly

EU261 has statute of limitations varying by country (2-10 years). But the sooner you file, the better your documentation will be.

Consider Multiple Apps

Eligibility calculators are free. Check what AirHelp, Flightright, and ClaimCompass say about your flight. Sometimes one sees eligibility others miss.

Don’t Accept Vouchers Blindly

Airlines often offer vouchers or miles to settle quickly. Know what your cash compensation would be before accepting alternatives.

The Bottom Line

Flight compensation apps work. They’re slow (3-8 months), they take a cut (25-35%), but they handle the bureaucracy that makes most people give up.

For EU flights with 3+ hour delays, checking eligibility takes 30 seconds. If you qualify, apps turn potential compensation into actual money at the cost of waiting and fees.

DIY works if you’re persistent. Apps work if you’re not.
