7E7
For newcomers on the "Schoolbus", the lifestyle is typically 2/3/4 tours to any European/UK destination, generally over the weekends with 12/13 days off per month.
On the 777, newbies will no doubt find a significant amount of hot destinations in the Summer (ABV, CAI, DAC, KWI, RUH, JED, TLV) and North American (ATL, DEN, EWR. YUL etc) in the Winter! Again mostly weekend work with about 13/14 days off per month. Not sure how frequently you could expect a reserve block (28 days).
Suggest you send a private email to NOD, who contributes regularly on this forum, and has this sort of information at his finger tips!
