The Oasis

Some qualifiers: If you have a flight going out of Terminal 4, do not have access to any other lounges, have a long long time to kill and don’t want to go into the city, and like Indian food, it’s worth shelling out the $ 45 day pass to here. The Lounge is included on some credit card programs and for Delta and a few other airlines, but I paid the day pass. If you only have a few hours to kill, I’d recommend having a nice steak dinner at the Palm further down the Terminal instead.
I came in on an incoming flight at about 3:30p for my 9p flight. I bought day access and settled in to a chair with a view of the gates and some of the runway. When I arrived, it was quite busy, but it cleared out after the Dublin and Amsterdam flights were called, and it stayed pretty quiet for the rest of my time there. There were some magazines and newspapers, as well as pretty good free wifi.
Some snacks were available (chips, sandwiches, fruit), as well as hot food (chicken masala, rice, soup). I’ve heard it’s always Indian food and the place smells like it, which is fine with me, but others might have a problem. Drinks were passable and self-​serve. The red wine was pretty bad, but the white was drinkable. The liquors were fine, but not too many mixers.
There is a shower, which I checked out — only one per gender, and it seems like you might need to ask for the towel at reception.
I left when the reception called my flight, and I had plenty of time (but not too much!) to get through security and to my gate. If I am in JFK again and have the same restrictions again, I would return here.
