Was with EZY for 15 years. Wouldn't ever say anything bad about them. They gave me many opportunities.
With J2 now almost 3 years. I work FAR less. Am far less stressed, spend far more time at home. I don't miss the fixed pattern at all as it was inflexible with regard to getting days off if they fell in a work pattern. Staff travel was ok, yes.
As with everything in this job, what suits one will not suit another. If you want lots of flying and to build hours, go orange. If you want less flying and more time at home go red. My thoughts having worked for both.
