Next month I am flying business to TPE from IND through JFK. This is a Delta ticket with the flight to TPE on China Airlines. We will have a 5 hour connection at JFK and I am wondering if my wife and I will be able to utilize the Delta lounge for the entire duration.

I have searched the forums and Delta's website and have been unable to find an answer. Our flight lands at JFK around 6pm and takes off at 1:20am so it technically isn't same day. Either way, I hope it is a moot point and that the AMEX lounge is open by then! Thanks!
