Hours against the security queue
Delta One Lounge opens at 4:30am and closes at 11pm. FlyIndex's wait-time data puts the typical JFK checkpoint queue at 28 minutes around 4am.
Across the week, JFK security runs longest around 8am at a median of 33 minutes, and lightest around 2am at 10 minutes. The queue is typically building before this location opens.
Queue figures are medians from FlyIndex's JFK wait-time record, not a live reading.
About this location
Delta's premium cabin lounge sits on Level 4 of Terminal 4, the same floor as the Chase Sapphire and American Express Centurion lounges, though its 4:30 AM opening beats the Chase room's 5:00 AM start by a half hour. It closes at 11:00 PM, the same time as Chase down the hall. Only the lounge feature itself is listed here, without the reading room or Wi-Fi call-outs attached to the Chase room next door, which reads as a narrower amenity list on paper even sitting on the same corridor.
