It will be interesting to see what happens with UA and JFK as others have mentioned. With the remaining few PS flights left, as others have mentioned, how long will they (United) will hang on to JFK.
It seems silly to operate a United Club and United Global First Lounge at an airport that will see less than 20 of their own flights per day, when the Washington flights end. I understand the dynamics of the lounges for the PS flights, but when the bottom line is what matters most to a company, there has to be more to this plan.
I live in NJ and I won't drive to JFK or LGA because of the distance, though plenty of my friends and family will go to NYC airports or PHL, based on the right price points or connections. I am hopeful one of those JFK-IAD flights can go to ACY. I know it won't happen, but we can dream.
