I have almost a whole day to kill at JFK before a 7:30PM flight to MAD on AA out of T8. Prefer to spend most of it in the Virgin Clubhouse and Centurion Lounge both in T4, but the Virgin Clubhouse doesn't open til 2PM and Centurion limits access to 3hrs before a flight. So I'm looking to be in a PP lounge from around 10-2. Is the KAL lounge worth the trek to T1 and back to T4? I really want to minimize the time spent going through security and all that hassle, but I'll do it if the KAL lounge is a much better place to to crash for 4 hours over Wingtips. TIA

Edit: Why does the PP app show way more lounge options than are listed in the wiki?
