I wonder why he wants to go back to JFK. Those transcontinental routes to my understanding aren’t the money minters they used to be. Then again he kept First Class on the A321s at AA to my amazement, so perhaps there still is an opportunity to make high profits on those flights.
I also know that JFK is still many corporate travelers go-to airport. I’ve never understood the aversion to EWR but again, perhaps it is just reality, and by not having JFK maybe the company loses out on some potentially lucrative corporate client contracts.
