@Babemagnet:
It looks like all the flights that would arrive back at Weeze after 23:00 are NOT bookable anymore. This means that some destinations(eg. Malaga) are not bookable anymore. I can understand this move by Ryanair as they are not sure if they are able to operate this flights.
And despite I believe dat reducing the opening times by 1 hour shouldn't make to much of a difference for Ryanair, it does create chaos in their summer schedules as most aircraft are timed to arrive back for the night between 23:00 and 24:00. It's more or less to late now to change the timings of all the other flights.
They will have to reschedule more or less all the flights for the winter season and try not to lose to many frequency's in that process.
