Well, now. I had an interview with Ryanair for work at STN, and I have to say that as far as I was concerned, the roster pattern would have been great. No nightstops; a very high ratio of flying to duty; distinct earlies and lates; no nightflights. The biggest problem from a rostering POV was people hitting 100 hour/28 day totals and having to have extra days off. I was invited to talk to the pilots to hear their comments. I would be happy to do about 900 hours a year on that basis. Unfortunately, I was not prepared to move to the job at that stage.
I have other reservations about Ryanair, but rostering wasn't one.
