If you are planning on going to Ibiza in the next few months you should be aware that the airport workers are going on 25 different 1 day strikes to protest low pay! This will of course impact travel. The days are to be:
September: 15, 17, 22, 24, 29
October: 1, 6, 11, 15, 27, 30, 31
November: 3, 5
December: 1, 4, 5, 7, 8, 10, 26, 27, 28, 29, 30
So those going for closing parties or NYE may be affected. It may be a good idea to purchase travel insurance!
