The day the merger happened, any and all service at JFK days were numbered and pre-ordained. Any accountant can make the numbers say anything you want.
If you include the costs of 757 upgrades, or not, maybe it's profitable, maybe it's not. Moving the PS to EWR will be a disaster. It would be better to discontinue all together, which I think, this is the first move to do so. Can you say, saving face?
I said it before, and I'll say it again, almost none of the current PS customers will fly out of EWR. They will go to American and Delta to fly out of JFK. That is the whole point. Unless you have flown it, or ridden on a PS plane you have no idea what the level of service is. It is vastly different from anything out of EWR or any other place in the system. More what UAL first class used to be, and should be if we are to compete. What we currently have is not first class service, not even close. This seems to be the same old run and hide tactic, along with the current go cheap philosophy, and hope no one notices.
If we are to compete, this is not how to do it. Delta will continue to dominate and we will continue to not be competitive.
