As for the roster. Ya you will get 26 of them in a year starting on a Monday, but I can asure you that after your first sector you can scrap it, you go where the freight goes/is.
Monday to Friday expect to operate at least 4 sectors a night and spending at least 2 hours sitting in the crew room in BRU.
Sat & Sun less sectors more boredom.
And if you get 8 days off the first you will spend in bed and the 8th also in bed getting some rest for that nights flying!
Happy flying
