Spain trip affected by a flight problem?

CostaSure also has a safe flight-disruption add-on for Spain-related trips. It helps organise first-stage evidence, refund/rerouting facts, airline complaint wording and possible AESA escalation preparation — without positioning CostaSure as a flight compensation claims company.

Flight delayed or cancelled

Check the facts, airline reason, refund/rerouting position and first complaint step.

Airline refund problem

Organise refund, voucher, travel-agent and airline-response evidence before escalating.

Missed connection

Check whether the journey was one booking, what caused the delay and what rerouting was offered.

Denied boarding

Prepare gate evidence, airline reasons, rerouting/refund offers and complaint wording.

Flight evidence checklist

Collect airline messages, boarding evidence, receipts and complaint history before escalation.

AESA complaint preparation

Prepare documents and chronology where Spain is the correct passenger-rights route.
