The question is what that means. If there's no cover from 1am to 5am, it won't make a massive amount of difference, but make that midnight to 6am and you will start running into problems, especially when things start running late. Even this evening, there's an 00:15 arrival from Alicante, so I can't imagine they will be looking to make a change that will impact on existing schedules, but with the IAA, who knows.
