I should also add that with the C&J bus service BOS is more convenient than MHT as well since they are approximately the same distance. MHT could only attract people from the seacoast area by offering better prices, which they don't anymore.
As someone who lives in the Haverhill/Plaistow area and has taken the C&J bus once from the Newburyport park&ride the convenience factor is directly related to how close you live to the bus stop and how your flight schedule coincides with the bus schedule because the bus only runs once per hour and it's really inconvenient to have to wait that long after arriving. That's why I switched to the Logan Express which is more expensive but far more convenient knowing that the most I will ever have to wait is 30 minutes.
These flights are pretty much compensation to Massport for preferred gate space at Logan. They want good treatment at Boston, they have to fly to Worcester, even if just token service.
I never bought into that theory. They have their own terminal. What compensation are they looking for?
B6 flies ORH-JFK. Massport made and earn with B6. They said if B6 wanted some extra GaTES in LOGAN, they would have to add ORH-JFK. Devil in the details
There is really no proof of that. Like AA, B6 has an entire terminal to themselves and they're nowhere near full utilization. In fact in the last few years it's Massport who has had to go begging B6 for gates in order to handle the overflowing international carriers at terminal E, not the other way around.
I'm under no illusions that if the flights don't generate profits they would be dropped, just as AA is doing.
