In short: EU261 Flight Delay is a free information website. It does not give legal advice, does not handle compensation claims and is not the official AirHelp website. The checker gives an estimate, not a promise. If you start a claim with AirHelp, AirHelp's own terms and conditions apply to it, not these terms.
1. The operator
The EU261 Flight Delay website (https://eu261flightdelay.com, the "Website") is operated by (the "Operator"):
WeOnline Kft.

These terms of use (the "Terms") apply to every visitor of the Website (the "User"). By using the Website the User accepts the Terms as binding. If you do not agree with the Terms, please do not use the Website.
2. Nature of the service
2.1. The Website is a free, English-language information site that provides general information on air passenger rights, in particular Regulation (EC) No 261/2004 and the Montreal Convention. No registration is needed to use the Website, and the Operator charges the User no fee.
2.2. The Operator does not provide legal advice and is not a law firm or legal service provider. The content of the Website is general and does not replace a legal opinion on an individual case.
2.3. The Operator is not a claims agency: it does not take on, submit or represent compensation claims, does not act on the User's behalf towards airlines and does not accept instructions to do so. The no-win-no-fee claims service previously offered by the team behind the Hungarian sister site Járatkésés.hu has been discontinued.
2.4. As an affiliate site, the Website draws attention through partner links to the service of AirHelp (AirHelp Germany GmbH, Berlin). The Operator is not the official AirHelp website, is not AirHelp's representative, and makes no statements on AirHelp's behalf. The details of the partnership are set out in the affiliate disclosure.
3. The compensation checker
3.1. The compensation checker on the Website gives an indicative estimate, based on the answers provided by the User and the general rules of the regulation, of whether compensation may be due in the given situation and how much.
3.2. The estimate is not a determination of entitlement, a legal opinion or a promise. Actual entitlement is decided by the airline or by the service provider instructed by the User (for example AirHelp) on the basis of the specific flight data, the cause of the disruption and the circumstances relied on by the airline; in case of dispute, the competent authority or court decides.
3.3. The checker runs entirely in the User's browser; the Operator does not record or forward the answers given, except where the User expressly asks for the result to be sent by e-mail, as described in the privacy policy.
4. Limitation of liability
4.1. The Operator compiles the content of the Website with due care, based on primary legal sources, and updates it regularly. The content is nevertheless general information reflecting the legal position at the time of publication or last update. Legislation, case law, airlines' conditions and AirHelp's fees may change.
4.2. The Operator accepts no liability for the completeness, accuracy or currency of the content, or for its applicability to the User's individual situation, nor for any loss, missed compensation or other disadvantage resulting from decisions taken on the basis of the content. The User uses the information on the Website at their own risk.
4.3. The amounts shown on the Website are the maximum amounts under Regulation (EC) No 261/2004 (and, for flights covered by UK law, UK261). The Operator does not promise or guarantee that the User will receive compensation of any amount.
4.4. The Operator is not liable for loss arising from temporary unavailability of the Website, technical faults, or errors occurring on the User's device or browser. The Operator aims for continuous availability but does not guarantee it.
4.5. The above limitations do not affect liability that cannot be excluded by law, in particular liability for damage caused intentionally or by gross negligence, or for breaches causing harm to life, physical integrity or health.
5. Third-party service: AirHelp
5.1. Through the partner links on the Website the User reaches the AirHelp website. AirHelp is an independent provider, separate from the Operator. Checking, submitting and enforcing a compensation claim, the fees and the payout form a relationship exclusively between the User and AirHelp, governed by AirHelp's own terms and conditions, fee schedule and privacy policy. The User can read these on the AirHelp website and should do so before starting a claim.
5.2. The Operator accepts no liability for the performance of AirHelp's service, the assessment of a claim, the amount or timing of a payout, AirHelp's customer service or its data processing, and has no insight into cases handled by AirHelp.
5.3. Information on AirHelp's fees published on the Website is indicative, based on AirHelp's public fee schedule, and refers to the date of the last update. In case of any difference, the terms shown on the AirHelp website when the claim is started prevail.
5.4. For successful claims started through its links, the Operator receives a commission out of AirHelp's fee. The commission does not reduce the User's compensation and does not increase AirHelp's fee.
6. Intellectual property
6.1. The entire content of the Website, in particular the texts, structure, graphic elements, logo and the logic of the checker, is the Operator's copyright-protected work, or the Operator is entitled to use it. The text of Regulation (EC) No 261/2004 and other legislation is not protected by copyright.
6.2. Reading the content for private purposes and linking to the Website are free. Reproducing, adapting or publishing all or part of the content on another website or in another publication without the Operator's prior written permission is prohibited; short quotations are allowed with the source (EU261 Flight Delay and the page title) stated.
6.3. Airline and other names and trade marks appearing on the Website belong to their respective owners and are used only for identification and information. The "AirHelp" name and logo are trade marks of AirHelp Germany GmbH.
7. External links
7.1. The Website contains links to websites of other providers, authorities, airlines and AirHelp. The Operator is not responsible for the content, availability or data processing of external websites or for transactions concluded there. External websites are subject to their operators' own terms.
7.2. Links to AirHelp are partner links, marked on the Website with rel="sponsored". How partner links work is described in detail in the affiliate disclosure and the cookie policy.
8. Obligations of the User
The User may use the Website only for its intended purpose, in compliance with the law and these Terms. It is prohibited to disrupt the operation of the Website, to copy its content in an automated or bulk manner, or to use the Website in a way that infringes the rights of the Operator, AirHelp or third parties.
9. Changes to the Terms
The Operator may amend these Terms unilaterally. Amended Terms take effect on publication on the Website, on the effective date stated there, and apply to use after publication. The version in force is always available on this page; the date of the last amendment is shown at the top of the page.
10. Governing law and disputes
10.1. These Terms and the use of the Website are governed by Hungarian law, in particular Act V of 2013 on the Civil Code, Act CVIII of 2001 on electronic commerce services and Act LXXVI of 1999 on copyright. If you are a consumer resident in another country, this choice of law does not deprive you of the protection of the mandatory consumer protection rules of your country of residence.
10.2. The Operator receives comments and complaints about the Website at contact@eu261flightdelay.com and replies within a reasonable time. In consumer disputes the User may turn to an alternative dispute resolution body; in Hungary these are the conciliation bodies competent for the consumer's place of residence. Otherwise, disputes are decided by the court having jurisdiction and competence under the applicable rules.
10.3. If any provision of these Terms proves to be invalid, the validity of the other provisions is not affected.
