This summer, the positions with First Choice / Thomson are in DUB with the 757 and BFS with the A320. My Travel / Thomas Cook have positions overseas on the A320 in LBA, STN and BFS. Skyservice pilots participating in these programs get accommodations, cars, and excellent per diems as well. It is a very lucrative program for the pilots, but as mentioned before, it's not for everybody. It's good for young pilots without families, or perhaps those with very young children, and for empty nesters as well.
Skyservice minimum requirements are around 3,000 hours, but don't expect any hiring there until the fall. It also depends on the winter program and how much growth there may be there potentially. When applying at Skyservice, understand the business model. If going overseas during the summer does not work for you and your situation, then don't bother applying. It will only make you and those around you pretty miserable!
