I can't comment on the W/B issues, but have used them from BOS successfully. Helpful, laid back agents in my experience. My experiences have been with fairly full flights (I was pax 8 of 9) and I was all the way in the back with a regular pax up front. (That's ok, I've got plenty of front-seat 402 time anyway....). Seems they could take a full boat with lots of luggage no problem, but this was summer weights with good VFR. Hope this helps a bit.
