I have been denied twice from JFK Centurion lounge, I already posted the first instance back in December. I had it happen again in February. Flying BR31 which leaves at 12:20am (before daylight savings) and wanted to try it out again since I was leaving the office and wanted to try to get work done at the airport. Was told the same thing, that they were a same-day lounge and I can't enter. I called AMEX and they said that each lounge can set their own rules. I guess they are following the terms though down to the letter. Hope no one has a 12:01 am flight.
Its extremely frustrating that this is a constant thing and I have to argue to no avail, and it makes me look like a crazy ....... in front of others. Going to end up canceling this card after I am past the 12 month mark from my retention, try for another retention, and then just close it and get United Club card because you get access to Star Alliance lounges and I only fly them.
