There is only going to be a handful of FO's going out to Greece for a full time stint with some spending a bit longer out there than the others. Bear in mind though that the number of Flybe aircraft based out in Greece is reducing now so less crew needed to crew the operation. Overall there is room in the system to let a couple of FO's go to Greece for a long stay although as several others have posted, there are a couple of bases around the network which are working hard, although there are also some that are not.
