TSG- Mate of mine is an FO for Polar. Last I heard, pay was about 38k PA plus per diem for a new FO. Bases are Long Beach and someplace in the midwest, i cannot remember. About 10 days off a month, the bloke said. And the last time i checked, may be wrong, they had no -400s. There was a write up of them in airline careers last year, you may want to check that.
