Update. I interviewed in Dec 2013, not quite at ATP mins, and was given a conditional offer based on completing mins. I have a received two e-mails since then, including one recently, requesting my progress and offering class dates based on reaching minimums. It sounds like they are still looking for pilots.

Random tangent: what are the odds that any AAG feeder would open a BOS base? Seems low, but AirWis seems the most likely. Thoughts?
