I'll do my best to answer some of the questions.
Alpha is currently not hiring and last I heard will not be hiring anytime in the near future. My guess would be next fall, but just a guess.
We just expanded our territory into Texas and Oklahoma and I would guess that when we do start hiring again, they will want to get some more crews in Atlanta.
The Grob - I have no clue. Grob filed for full insolvency a couple weeks ago and as far as whats gonna happen with them and our jets, your guess is as good as mine.
7/7 - expect to be gone all 7 days. I guess the PSM guys do get some day trips mixed in, but us PDK guys are typically called out for the majority of the 7 days.
On days off, a lot of people have part time flying jobs. I personally have not been able to find anything that would work with my schedule, so I get a lot of work done around the house and get to sleep in quite a bit.
