‘Outpost base’
True overseas bases happen rarely these days and only with the legacy carriers and permanent employees. . What might be advertised as an overseas base for contractors is really just the approval to live where you want but, make your own way to work and back ( sure , using company tickets If they cover the route ). I have seen pilots having to commute for more than 24 hours plus waiting time , one way. In some cases these ‘bases ‘ open and close at the whim of the company and you may find yourself back at the main base. If you operate on a 20 on/ 10 off contract and you have to take 2 days to commute , arrive too late to catch a flight home plus , leave a day early on your way back ( so that you can be sure that you don’t miss a flight) , that might make it only 6 days home a month or less. Not easy . Want to move to the US? Do so but, get a job there.
