Like I said. If that's the reason why a return isn't worth it, which is reasonable, that means JFK was a marginal operation at best on the overall bottom line. That makes his blanket "wrong move" statement very suspicious. If an operation is only worth the capital already placed into it, then it's not lucrative and worthy to be cut if that capital can be used elsewhere for better effect (which has happened at EWR).
A return to JFK would be a mistake according to his own admission unless capital costs (including the need for more aircraft) plummet.
