If you instructed from last March to May, that's about 14 months of instructing, and if you're busy, maybe about 750-900 hrs for that neck of the woods with New England WX and whatnot. That's plenty of great experience under your belt. If you don't want to stop instructing and keep a couple of students or instrument reviews or BFR's then do so. BUT, flying at Eagle, let's say, will be a full time job, and you'll be learning a whole new skill set, using your valuable instructing experience as the background, with little time for full-time instructing on the side. If you want to make a legitimate go at an airline career and stay close to BOS, the Eagle option is a great way to get started on that path. It's a golden opportunity. Finish School. Go to Eagle.
