Question 1

How much does ClaimFlights charge?

Accepted Answer

ClaimFlights charges approximately 27-30% of the recovered compensation as their fee on EU261 and UK261 claims. TravelStacks charges 25% for the same claim types, and $19 flat for US DOT refund and reimbursement claims, which ClaimFlights does not offer.

Question 2

Does ClaimFlights cover US flight claims?

Accepted Answer

No. ClaimFlights is built for EU261 and UK261 compensation claims. If your disrupted flight departed from a US airport, you need a service that handles US DOT rules. TravelStacks covers DOT refunds, expense reimbursement, and denied boarding for US flights.

Question 3

Is ClaimFlights a trustworthy service?

Accepted Answer

ClaimFlights is a legitimate flight compensation service with an established Trustpilot presence and several years of claims history. TravelStacks is newer, launching in 2026, with a no-win, no-fee guarantee and a lower fee structure.

Question 4

Which service is better for a London to New York disruption?

Accepted Answer

The London to New York flight departs from the UK and is covered by UK261. Both ClaimFlights and TravelStacks can handle this, but TravelStacks charges 25% versus ClaimFlights' 27-30%. On a 520 pound UK261 claim, you keep more with TravelStacks.

Question 5

Can I switch from ClaimFlights to TravelStacks mid-claim?

Accepted Answer

If a claim is already in progress with ClaimFlights, review your agreement before switching. For any new claims, including past disruptions not yet submitted anywhere, you can use TravelStacks regardless of which service you have used previously.

Question 6

What is TravelStacks' Flight Watch feature?

Accepted Answer

Flight Watch monitors your upcoming flight in real time. If the flight is disrupted, you receive an immediate alert so you can begin your claim before the airline queues fill up. ClaimFlights does not have an equivalent proactive monitoring service.

Question 7

Does TravelStacks handle connecting flight claims?

Accepted Answer

Yes. If a disruption on the first leg caused you to miss a connecting flight, we assess the full itinerary. EU261 and UK261 cover the final destination delay, not just the first leg. We apply the same analysis for US DOT connecting flight claims.

Question 8

What happens if the airline denies my ClaimFlights or TravelStacks claim?

Accepted Answer

Both services escalate denied claims. TravelStacks escalates through automatic follow-up, then DOT complaint for US claims, or national enforcement body referral for EU/UK claims. The escalation path is included in the standard fee. No surprise surcharges.
