Aer Lingus operates from Terminal 4 at Madrid Airport, where passengers can complete check-in, baggage procedures, security screening, and other departure formalities.

The Aer Lingus Terminal Madrid provides passengers with a range of services and facilities. After reaching Terminal 4, travelers can follow the airport signs toward the Aer Lingus check-in area.
