Apologies if this question is obvious or has been answered elsewhere. I'm currently trying to book a flight from YYZ (Toronto, Canada) to YHZ (Halifax, Canada) on December 22, but prices on Air Canada, WestJet, and Porter (our three main airlines) are sky high. I'm currently looking at doing YYZ-BOS on AA, with arrival in BOS at 11:00am, and trying to catch a BOS-YHZ flight on DL at 12:15pm.

The question: if I do OLCI for the BOS-YHZ flight before I leave Toronto, do you think I'll have enough time to arrive at BOS at 11:00am, get my bag, go from Terminal B (AA) to Terminal A (DL), drop off my bag with the check-in attendant, and make my 12:15pm flight? I know it sounds a bit ludicrous but I'm unfamiliar with BOS... suggestions appreciated.
