A few thoughts, those knocking American in favor of delta with a stop I would ignore. American does a fine job on the route and is far better that going thru Atl. If you fly luv just buy early boarding and the seating is fine though I would agree I don’t much care for the way they board. If you are flying coach jet blue is more comfortable than regular coach on any of the other options and they have a huge operation in Bos. The only negative with jet blue is they dont interline with other airlines so your options can be limited if there is an issue and they only have one or two flights a day.

Between the two airports. I think it is really about schedule and convenience

i always fly american
