lederhosen & denti, you are both correct it seems on turnaround times.
RYR seems to adopt turnaround time in excess of 25 minutes where required, even up to 45 minutes in IBZ in summer on some flights.
look at their schedule in Canaries and compare arrival from and departure to any of their bases, e.g. flights flown by crew from that base, and you will see a mix of 25/30/35...
