For those unaware, Palma has had truly unusually terrible weather in the last few days, right in the holiday season. It's caused a lot of disruption, and not just to aviation, with trees down and ships cast from moorings.
Yes, I'm one of those who says that if you have the option of leaving a little later then don't rush, wait to see what happens since it's going to be a fast changing situation. From a contact centre perspective, you can very much see the point of "one go only" at changes, and further more making repeated calls to make small time changes is unhelpful at a time of pressure. So it's best to research offline (or use this forum if you aren't good at that) and then ring up with a clear request. PMI unusually is served by 3 airports and there is a problem there that the Disruption menu online may not give all the options that are available.
