2.3 Service Limitations

TravelStacks is not a law firm, airline, travel agency, or regulatory body. We do not guarantee specific outcomes. The Service is limited to the claim types and jurisdictions described herein, and eligibility determinations are estimates based on available data at the time of assessment.

3. Eligibility

3.1 Age Requirement

You must be at least 18 years of age to use the Service or submit a claim.

3.2 Authorized Representatives

You may use the Service on behalf of another passenger (such as a minor child, spouse, or traveling companion) if you are their authorized representative. By submitting a claim on behalf of another person, you represent that you have the authority to act on their behalf and to bind them to any agreement entered into through the Service.

3.3 Claim Ownership

You represent that you have a legitimate ownership interest in the claim you are submitting, that the claim has not been previously assigned or transferred to any third party, and that you are not simultaneously pursuing the same claim through any other service, legal representative, or directly with the airline.

4. Account Registration

4.1 Account Creation

To submit a claim, you will be required to create an account or authenticate through our authentication provider. You agree to provide accurate, current, and complete information during registration and to keep your account information updated.

4.2 Account Security

You are responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account. You agree to notify us immediately at support@travelstacks.com if you suspect any unauthorized access to your account.

4.3 Account Accuracy

Providing false or misleading information during account creation or claim submission may result in termination of your account and forfeiture of any pending claims.

5. Service Fees

5.1 US Refund and Reimbursement Claims

For claims seeking a refund of a purchased ticket or reimbursement of out-of-pocket expenses under US DOT rules, TravelStacks charges a flat fee of $19.00 USD per claim. This fee is charged at the time you authorize the claim via our checkout process and is non-refundable once the claim has been submitted to the airline. The flat fee covers all follow-up, escalation, and regulatory complaint steps required to recover your refund.

5.2 Compensation Claims (Success Fee)

For claims seeking fixed cash compensation under EU261, UK261, or US DOT involuntary denied boarding rules, TravelStacks charges a success fee only if compensation is successfully recovered. No upfront payment is required. The applicable success fee tier is determined by the effort required to recover compensation:
  • (a)25% of the recovered amount if the claim is resolved through standard direct submission to the airline;
  • (b)35% of the recovered amount if recovery requires follow-up, dispute correspondence, or pushback on a denial;
  • (c)45% of the recovered amount if recovery requires escalation to a regulatory body, National Enforcement Body, the Civil Aviation Authority, or the US Department of Transportation.

The applicable fee tier will be disclosed to you before any payout is processed. You will always be shown the net amount you will receive after fees before disbursement is completed.

5.3 No Recovery, No Fee (Compensation Claims)

For compensation claims under Section 5.2, if TravelStacks is unable to recover any compensation on your behalf, you owe no fee whatsoever. The success fee applies only to amounts actually recovered.

5.4 Fee Changes

TravelStacks reserves the right to modify the fee structure described in this Section. Any fee changes will apply only to claims submitted after the effective date of the modification. Fees applicable to a claim are fixed at the time the claim is authorized.

6. Claim Process

6.1 Eligibility Assessment

Upon submission of your flight details, TravelStacks will assess your claim for eligibility based on available flight data and applicable regulations. Eligibility assessments are estimates. Final eligibility is determined by the airline and, where applicable, regulatory authorities.

6.2 Claim Submission

Once you authorize a claim, TravelStacks will submit the claim to the relevant airline on your behalf. We will include all information required by applicable regulations and the airline's stated claims procedures.

6.3 Follow-Up and Escalation

TravelStacks will follow up with the airline according to our standard escalation schedule. If the airline does not respond or denies a valid claim, we will escalate through available channels including formal demand letters, regulatory complaint filings, and other reasonable measures. We do not guarantee that escalation will result in a successful outcome.

6.4 Timelines

Claim resolution timelines vary significantly depending on the airline, jurisdiction, and claim complexity. Typical resolution times range from a few weeks to several months. We will provide updates on the status of your claim through your account and via email or SMS as significant developments occur.

6.5 No Guarantee of Outcome

TravelStacks does not guarantee that any claim will result in compensation or that any specific amount will be recovered. Airlines have the final authority to accept or deny claims. Regulatory complaints and legal proceedings have uncertain outcomes. Our role is to pursue your claim diligently and in good faith, not to guarantee a result.

7. Authorization

  • (c)File complaints with the US Department of Transportation, EU National Enforcement Bodies, the UK Civil Aviation Authority, or other applicable regulators;
  • (d)Negotiate settlement of your claim with the airline;
  • (e)Receive funds recovered on your behalf, deduct applicable fees, and remit the net amount to you.

7.2 Scope Limitation

This authorization is limited to the specific claim submitted and does not constitute a general power of attorney. TravelStacks is authorized only to take actions reasonably necessary to process and recover your claim.

7.3 Revocation

You may revoke this authorization at any time by contacting support@travelstacks.com. See Section 13 (Termination) for the consequences of revocation.

9.3 Essential Basis of the Bargain

The limitations of liability set forth in this Section reflect a reasonable allocation of risk and form an essential basis of the bargain between TravelStacks and you.
