Travelling DUB-LAS next Saturday with a 6 hour stopover in JFK. We are flying with Delta. I have been given two One-time passes into the United club Lounge and am wondering is it possible to use these passes while travelling on Delta? We fly into terminal 3 and I think the United lounge is in terminal 7, so is it even possible to do it? Just looking for a way to pass in a long 6 hours.
Thanks for any advice.
