I worked there from 1997-1999. It was great then but I hear things are now different, and not as positive. The management is now mostly Saudi although many of the pilots are expats. To the best of my knowledge they are still partial to hiring U.S and Canadians.
They offer an excellent pay package, housing, vacation etc. F/O's can expect to make 70-80K USD taxfree. Capts probably 120K. The fleet consists of 737-700's, DHC-8's, CE-550, DHC-6, Hawkers, GIV's. The 767 is based in Houston. You can find openings and minimum requirements at

Negatives include management indifference (I'm told), living in Saudi and the constant threat of terrrorism (Abqaig-recently). Think hard if you have a family and plan to go there.
