Flight compensation in Spain: how to escalate a refused claim.
Spain has quietly become one of the best places in Europe to enforce EU261. Since 2023 the aviation authority AESA runs a dispute resolution procedure whose decisions bind the airline — a rarity among national enforcement bodies — and the court route for small claims is designed to work without a lawyer.

Key takeaways
- AESA is Spain's EU261 enforcement body — and unusually, its post-2023 ADR procedure produces decisions that bind the airline (while leaving you free to go to court if you disagree).
- The AESA procedure is free for passengers; you must first have claimed from the airline and been refused or left waiting.
- The limitation period for these claims in Spain is generally 5 years.
- For the court route, the juicio verbal small-claims procedure can be used without a lawyer or procurador below the statutory thresholds.
- Because AESA's route is binding on the carrier and costs nothing, it is usually the strongest first escalation in Spain.
What qualifies — and what usually doesn't
May qualify for compensation
- Your flight departed a Spanish airport on any airline, or arrived in Spain on an EU/EEA carrier.
- You have a qualifying EU261 disruption: a 3+ hour delay at the final destination, a short-notice cancellation, or denied boarding.
- You claimed from the airline in writing first and it refused, underpaid or failed to respond within the expected window.
- You are within the Spanish limitation period — generally 5 years.
- Your dispute falls within the scope of AESA's ADR procedure (EU261 and related passenger-rights claims).
Usually excluded
- Disruptions the airline proves were caused by extraordinary circumstances (for example severe weather or air traffic control restrictions).
- Claims brought after the applicable limitation period has expired.
- Flights with no Spanish or EU261 connection (for example a non-EU airline between two non-EU airports).
- Disputes filed with AESA before the airline has been given the chance to answer your direct claim.
Rights by jurisdiction
The Agencia Estatal de Seguridad Aérea (AESA) is Spain's designated enforcement body for EU261. Since 2023 it runs an alternative dispute resolution procedure for passenger claims that goes further than most European regulators: its decisions are binding on the airline.
The procedure is free for passengers. You must first claim from the airline; if it refuses or does not answer within the expected period, you can file with AESA, which examines the case and issues a decision. If AESA finds in your favour, the airline is obliged to comply — you, by contrast, remain free to reject the outcome and go to court.
What to do
- 1Send the airline a written claim with your flight details and keep proof of the date.
- 2If the airline refuses or stays silent, file the dispute with AESA — the procedure is free and its decision binds the airline.
- 3Diarise your deadline: the limitation period in Spain is generally 5 years, but evidence fades fast.
- 4If your case falls outside AESA's scope or you disagree with the outcome, consider the juicio verbal — no lawyer needed below the thresholds.

Frequently asked questions
Is AESA's decision really binding on the airline?
Yes. Under the ADR procedure AESA has operated since 2023, a decision upholding the passenger's claim is binding on the airline, which must comply. The asymmetry favours you: the airline is bound, but you can still reject the outcome and take the claim to court.
Does the AESA procedure cost anything?
No — it is free for passengers. You need to have claimed from the airline first and been refused or left without a satisfactory answer before filing with AESA.
How long do I have to claim in Spain?
The limitation period for these claims in Spain is generally 5 years. As always with limitation rules, the exact computation can depend on the circumstances of your case, so it is safest to claim well before the deadline.
Do I need a lawyer to sue an airline in Spain?
For small claims under the juicio verbal procedure, no — below the statutory thresholds you can act without a lawyer or procurador. In practice, most passengers resolve refused claims through AESA's free binding procedure before court becomes necessary.
