RYR only need to hang on until the clocks change and then enjoy another 6 month respite before the next season starts.
I wouldn't be so sure. Their 900 calendar year reverted to start on January 1st this year (I believe), so by the end of the Summer many of them will be very high on hours - the schedule will slow down slightly but that's when the months off begin.
They may breathe a sigh of relief on January 1st, but it will be short lived. If they can't crew the aircraft now, they have no chance with expansion. It's absolutely fantastic to see, imagine how many additional flights would be cancelled if their crew had the balls to call sick or fatigued when they're...sick or fatigued.
