PVD is an airport that is sadly in need of runway expansion but the locals are fighting this tooth and nail. The majors want a longer runway to allow non-stop west coast flights. Southwest is the 'big kid' on the block here and their lift out of PVD is formidable. Recent changes in the routing of arriving passengers directly into the baggage area were positive. Parking rates border on the insane but if you park off-site with a shuttle you can get a fairly good deal. Certainly a great alternative to BOS.
