Denied boarding on a Spain-related flight?
A safe first-stage checklist for passengers who were not allowed to board and need to organise evidence, airline reasons and complaint wording.
Safe CostaSure add-on: flight delay, cancellation, refund and rerouting issues are included as a supporting Spain-travel category. CostaSure helps organise first-stage evidence, complaint wording and escalation preparation.
CostaSure is not positioned as a flight compensation claims company and does not promise a compensation outcome. For the main CostaSure complaint areas, see all complaint categories.

Do not rely only on verbal explanations
A denied boarding dispute can become difficult if the passenger has no written reason, no time evidence and no proof of what the airline offered. CostaSure helps you organise the chronology and missing evidence before you escalate.
Prepare your denied boarding complaint clearly
Start with the facts, the airline’s written reason, the rerouting/refund offer and your supporting evidence.
