Thread: Thinking outside the box and inside a JFK lounge

My dad and 2 brothers have a 5 hour layover in JFK on Wednesday en route to TLV from IAD on DL. He was considering buying a DL lounge pass @ $50 but realized that no guests are allowed, so it would actually be $50 x 3.

I'm trying to figure out something to see if I can get him in to ANY JFK lounge for a reasonable rate (~$50 for all 3).

I have:
Amex Plat/PRG
Chase SP/Ink Bold/Freedom
Lounge Club (via Bold)
PP Select (via AX Plat)

He has:
DL Amex Plat (which appears to conveniently have 0 lounge passes per year despite a hefty annual fee)

My first thought was to rush him an Ink card and get the Lounge Club, but I'm not 100% sure AU's get Lounge Club and I'm relatively certain he wouldn't be able to get everything in hand by Wednesday morning.

(Actually my first thought was to tell him to get a better earning card, but he's stubborn)

Any options I haven't considered? Any more economical lounges in JFK they can buy into for the day?
