Don't expect 3 ULR ( Ultra Long Range ) trips per month as they are limited to 2 for health reasons. However, 2 of these plus a Europe will get you up to the months flying target so should achieve anything up to 17 days off. Don't count on this in your bottom 2 bid months though.
Regarding F/O pay, yep, it's not a lot and it's getting very expensive here. Some basic food items, including eggs, bread and cooked chickens, soared by 50% at the start of the New Year. Yes, that's 50%! The same will happen again after the summer holidays when the shops increase the prices, hoping the housewives who were away for the summer will fail to notice the rise! Greedy gits!
