Hi Conti..57!
Hope it's not too late for you, but as I am myself just starting as an expat pilot with them I can give you some more exact figures.
Salary for expat will be around 3500. Roster is normally 3 weeks on, 1 week off with flights to home base payed for by the company.
They have operations in Libya, Riga, occasional charters and flights on their own network.
Hotels differ a lot. In Riga you are in a Radisson, in TSR the hotels in town are quite ok, the one at the airport not so much (luckily haven't been there till now).
Right now you can apply directly or via Aero Professional. T&C's don't differ that much.
If you have any other questions, feel free to ask or PM!
