I worked in AK about 10 years ago, and PenAir was a good place then, so I assume it has remained so.. Be careful up there as there are a lot of crap operators.. You meet people in the bars one night and read baout them dead on a mountain trying to fly some junk plane in IFR and icing days later... Stick with the good reputation companies where you can jumpseat, have a life and enjoy AK.. Under the right situation (airline) it can be a great time; was one of the best experiences of my career..
