Greyhound Bus Co. is matching the Chinatown service, they also are charging $15.00 ow.
This is indeed true. But the Chinatown bus tends to be faster as it doesn't stop anywhere along the way (except for a 5 min rest stop somewhere along the way). But it also depends where you want to be on Manhattan. Chinatown...or Penn Station. I'm personally a huge fan of the JetBlue flight. But any of the services BOS-NYC are fine...its a quick flight. Except AA uses RJs instead of mainline service.
