In summer you will usually be on an early airline on day 1 and most likely you will then operate between 1 and 3 flights that day. Nightstop with minimum rest (11 hours or length of previous duty period, if longer than 11 hours), 3 to 4 legs, next hotel, next min rest of 11 hours or longer etc.. You will probably fly 15 to 20 legs during a tour. If they keep you really busy, you might end up with 55 hours of duty on day 5 and they'll send you home already. If you were unlucky and had a slower day before, you'll finish on day 6 and if they squeeze in just one flight before going home. When they are short on crew, like this year, they might ask you to agree to extend your duty (NOT flight duty!) to 65 hours for the week, but they can only use duty in excess of 60 hours to position you home. And you get extra money for it.
The summer is usually busy and you will regularly hit 58 to 60 hours of weekly duty. Winters are slower and good to take a breath and actually enjoy some time off or on STBY in a hotel to do other things than sleep-eat-fly-eat-sleep.
