Hi There,
It not a problem leaving the country on days off. On the crew portal you click on the off base request and go on your trip...
There are 12 female pilots with ek. Some single others married. I know some of the hubbys are working.. It wont be a problem.
EK is different from a US carrier. Dont expect to be taught everything. Expect to study hard in you own time and answer questions from the instructors.
Cheers
