Virgin Nigeria
I just attendant the first interview in London last week. VK does not provide transportation to the first interview. They will cover the airfare if you make it past the first interview.
It seems the salary for FO is about 50,000 US. But everything is negotiable. As far as days off they follow the regulations for England. They are hoping to put into place 2 weeks off every 3 months for expats, but they can not do that now because of staffing. They do not provide the airfare back home.
They do pay for your room and board, and meals on the plane.
