I'm sure UK109 is close to the mark, there are good and bad experiences in all airlines, a lot really does come down to personal circumstances and crucially how the roster fits your home life, we would all like zero roster disruption but thats not realistic and in Summer Jet2 are very very busy and delays and changes are a fact of life when working older aircraft very hard. On the positive side winters are a breeze provided your on a 100% contract.
