Can only agree about what has been said regarding airBaltic. Still if you come with your own rating I dont think there will be any bonding so you can always leave again
So if you dont have any hours you will at least get started.
It is Air Iceland that flies F50 in Iceland. I have heard it should be a nice company with good conditions.
BUT you have to be able to speak icelandic and they are not getting short with pilots.....
Never the less you can always give it a try
Good Luck!
