If you are catching a flight from Palma airport, arrive three hours earlier than your departure time because of the long queues at passport control. This is the conclusion I have come to after talking to a large number of readers who have been caught up in the scandalous lack of police at the airport. The blame can be firmly attached to the interior ministry in Madrid. It should ensure that there are the necessary resources available at the airport, especially during the peak summer months. One reader told me yesterday that he had queued for about two hours at Palma airport, while the whole process was completed within a matter of minutes at Edinburgh airport.
