Will keep saying this
UNITED WILL NEVER BE 100%!!!!!!
It's NOT a CHARTER........
United would be expecting a minimum of 80-90%+ LF during the summer and the 60% been achieved wouldn't even be acceptable in winter where 70%+ would be the norm.
Frequency can't really be cut any more and with it's performance so far it's a question of when it will be scrapped not if, they would probably achieve a higher return operating a 3rd daily EDI-EWR....
Aren't BRS also looking to return a NY connection, lots of competition for the 752!
If United goes it will be down to pricing simple as that , Im not so sure a 757 direct is any more appealing than a few more hours spent traveling on KLM / BA / AF on better aircraft and with a cheaper bill
Suprisingly though it is the Business seats that are being filled and economy that is struggling !
You need Y to preform very well on such routes also, 16 seats in J is nothing to most carriers.
