Doesn't make sense at all.

Factor in:
1. Take a train to EWR: time consuming on NJ Transit, and/or drive via NJ Turnpike: heavy traffic and tolls.
2. Then fly from EWR back into PHL: redundant , to head to BOS.
3. cost of checked bags on US

The nonstop flights via US (from PHL) and CO (from EWR) generally range from $250-$550 easily.


A better solution from the Philly side, is to drive to the Wilmington, Del Amtrak station (no toll from Philly, $4 from So. NJ, but an easy drive from So. NJ via I-295) book a $34 Amtrak ticket to BWI, then the $39 JetBlue or Southwest ticket from BWI-BOS. Of course, you'd hope for no delays on Amtrak to avoid being delayed to the airport.

Still it consumes 4-7 hours or almost a day of travel with the drive, the train ride, then getting to the airport, or probably the same vice versa going into PVD, then figuring the way to BOS affordably, or taking Amtrak all the way.

ACY is about a 1 hour drive from Philly.
The ACY-BOS flight via Spirit is the shortest duration for still < $100, reaching BOS (not PVD or MHT), but there is only 1 flight a day via Spirit. Fares can be as low as $29 (+ $19 checked bag fee).

SJTA is advertising ACY all the way up by Newark Airport. Nice but useless. I can't see a great benefit from someone in Northern or Central NJ driving down to ACY, pay all the tolls, to fly on AirTran or Spirit, both with checked bag fees. SJTA could be doing a lot more advertising just within the eastern half of the Philadephia metro. AirTran has more Atlanta flights, and connections, from PHL anyways, so they can't make ACY more enticing on that airline for those where ACY is really out of the way.
