Avoid this airport if you can.
When arriving at Mykonos airport the 1st August, and a Saturday, in the peak of the holiday season, 3 flights were leaving at the same time and only 2 check-in desks were open. It took 2.5 hours to check in one luggage. No effort has been made to speed up the process. There was not a single information screen or announcement to tell about delays and no staff was visible. The checked-in bags security is made manually by the passenger and you need to go through the other queues. It's very messy and disorganized. The departure lounge is small and very crowded. Boarding was painfully slow, more than 45 minutes to board an Airbus 320. Our flight was delayed 2 hours simply to allow private jets to land and our plane was not supplied with water. The service provided by the airport is unacceptable. Mykonos has been a popular destination for decades but their airport is below any acceptable standards.
