  Best for: Passengers comfortable paying a higher fee for name recognition and EU/UK claims (AirHelp) vs Passengers seeking lower EU/UK fees and US DOT coverage (TravelStacks)

• ›

  Verdict: Both services recover EU261 and UK261 compensation effectively. TravelStacks charges less on EU/UK claims and adds US DOT coverage. AirHelp offers broader Montreal Convention handling.

AirHelp has processed over 2 million claims since 2013, making it by far the largest flight compensation company by volume. Trustpilot reviews for AirHelp show a pattern that is common to the industry: strong satisfaction when claims succeed, significant frustration when claims take longer than expected or when the fee reduces the final payout below what passengers anticipated.

• ›

  Positive reviews commonly cite: High success rates on valid EU261 claims, thorough documentation handling, and the convenience of not having to deal with airlines directly.

• ›

  Negative reviews commonly cite: Unexpected fee amounts (some passengers did not realize the percentage cut), long wait times on complex cases (some exceeding 12 months), and difficulty cancelling a claim once submitted.

• ›

  Fee surprise: AirHelp's fee ranges from 25% to 35% depending on claim complexity. Passengers who selected AirHelp expecting a 25% fee sometimes received a lower payout than anticipated when the 35% tier applied.

• ›

  Communication gaps: Some reviewers report difficulty tracking claim progress and delayed responses to follow-up inquiries.

How to read claims service reviews: Look for reviews specifically about your claim type (EU261 vs Montreal Convention vs US DOT). A service that excels at EU261 claims may be less experienced with US DOT refund processes. Fee transparency is also key: always confirm the exact fee percentage before submitting.

AirHelp uses a tiered fee structure that varies by claim type and difficulty. This is an important distinction from services that charge a flat percentage on all claims.

• ›

  Standard EU261/UK261 claims: 25% of compensation recovered.

• ›

  Complex or legally contested claims: Up to 35% of compensation recovered, plus potential legal fees in some jurisdictions.

• ›

  AirHelp+ subscription: AirHelp offers a subscription plan that reduces the per-claim fee for frequent flyers. Annual fee in the range of $30 to $50, with reduced percentage on successful claims.

• ›

  No upfront cost on basic claims: AirHelp does not charge upfront fees on standard EU261 and UK261 claims. Fees are deducted from the recovered compensation.

For comparison, TravelStacks charges a flat 25% on all EU261 and UK261 claims and a flat $19 for US DOT claims. AirHelp does not offer US DOT claim processing. If your disruption involved a US domestic flight or a US-international flight where DOT rules apply, AirHelp cannot help and TravelStacks can.

Independent data on claim service success rates is limited because companies are not required to publish their approval percentages. What is known comes from passenger advocacy research and industry reports.

• ›

  EU261 success rates (industry-wide): Roughly 50-60% of claims submitted through services like AirHelp result in payment after full escalation. Many of the failures are claims that did not qualify in the first place (genuine extraordinary circumstances, flights outside the regulation's scope).

• ›

  AirHelp's own published data: AirHelp has claimed approximately 85% success rates on claims they accept. This reflects that AirHelp screens claims before accepting them, not that 85% of all submitted cases succeed.

• ›

  What 'success rate' means: A claim service that only accepts clearly qualifying cases will show high success rates. The more relevant metric is how the service handles borderline cases and contested denials.

Both AirHelp and TravelStacks pre-screen claims before accepting them. The most important question is how each service handles airline resistance on borderline cases, specifically whether they escalate to ADR bodies and regulators or simply accept the airline's denial.

AirHelp does not process US DOT refund claims. This is a significant limitation for American passengers whose primary flight disruptions involve domestic US routes or US-international flights operated by US carriers from US airports.

US DOT rules apply to flights to, from, and within the United States. If your Delta flight from New York to LA was cancelled and you are owed a cash refund, AirHelp cannot help. TravelStacks handles US DOT claims for a flat $19 fee, covering the full refund claim, DOT complaint filing, and follow-up.

• ›

  When to use AirHelp: EU261 and UK261 claims on EU or UK airport departures. Montreal Convention claims for international flights not covered by EU261.

• ›

  When to use TravelStacks: US DOT claims (flat $19), EU261 and UK261 claims at a competitive 25% rate, and cases where you want both US and EU/UK claim handling from a single service.

The choice comes down to three factors: the type of claim, the fee you are comfortable paying, and whether you need US DOT coverage.

1. 1

   Identify your claim type. If your disrupted flight departed from an EU airport, EU261 applies. UK airport: UK261. US airport on a US carrier (domestic or international departure): US DOT. See which law applies to your flight for the full decision tree.

2. 2

   Compare fees for your claim type. For EU261/UK261: AirHelp charges 25-35% vs TravelStacks 25% flat. For US DOT: AirHelp does not offer this, TravelStacks charges $19 flat.

3. 3

   Consider claim complexity. Both services handle straightforward claims similarly. For contested denials requiring ADR or court escalation, both have experience. TravelStacks is newer but handled escalation to the DOT, CAA, and EU NEBs.

4. 4

   Read service-specific reviews. For your airline and claim type, search for reviews mentioning that airline specifically. A service may have excellent results against Ryanair but limited experience with American Airlines EU261 claims.

The bottom line: Both AirHelp and TravelStacks are legitimate options for EU261 and UK261 claims. AirHelp has larger scale and name recognition. TravelStacks offers a lower flat fee, covers US DOT claims, and is built specifically to serve both US and international passengers.
