Terminal layout and lounge access
JFK is split across six terminals with no single airside link between all of them. Your lounge options depend entirely on which terminal your flight departs from — Amex Centurion in Terminal 4 is useless if you depart from Terminal 8 without a long landside transfer.
Terminal 4 serves Delta, Virgin Atlantic, and many SkyTeam and international carriers. Terminal 8 is American Airlines' home. JetBlue Mint Lounge in Terminal 5 is among the best domestic US airline lounges. British Airways still uses Terminal 7 on select departures.
UK traveller notes
Most UK–JFK routes arrive into T4 (Virgin, Delta, BA on some flights) or T8 (BA, AA). For connections onward within the US, verify whether your itinerary stays airside or requires baggage reclaim and re-check — many JFK connections are not protected through a single terminal.
