As an Iberia user recently, the service is ****.
I hadn't checked in at San Javier to Madrid, knowing the aircraft hadn't yet left Madrid. Why would I move to the airport rather than sitting at home?
I arrived 30 minutes before the aircraft landed and was told I couldn't board, the gate had closed. Despite the ******* gate never having ever opened to begin with!!!
As a customer, sink this crap airline and let something worthwhile replace it.
