On our long route back home from Necker Island (EIS-SJU-JFK-SFO), we had the opportunity to visit the Virgin Atlantic Lounge at JFK (operated by Plaza Premium) using the Amex Platinum card. Our flight was at 6 pm, so our plan was to lounge hop Bobby Van’s Steakhouse, Centurion Lounge, and Virgin Atlantic. After we picked up our to-go order at Bobby Van’s, it was 3 pm, so the Virgin lounge had just opened. We decided to go there first since it was further inside Terminal 4 than Centurion, which was right next to security. But the minute we stepped inside the lounge, we scrapped all plans to go to Centurion.
