This...planes are only faster on paper. Still gotta deal with check-in, security, boarding, un boarding, and getting to/from the airport at both sides.
I used to live in RI and worked like a 10 minute walk from PVD with a job that would do a lot of travel. I would always take the train to NYC. Way more convenient and faster to directly to Midtown Manhattan.
DC was iffy. Nowadays I'd probably take the train, (if only because DCA is a shitshow...though I do enjoy the view during takeoff/approach...can usually see most of the sights and some are more impressive from above (Pentagon, Arlington Cemetery, etc))...but I don't travel for work anymore.
