Here's the situation. Jack and Jill have no status but are flying CO in December DEL-EWR-SFO (11:45pm departure). Jill's cousin Jane will also be leaving DEL that night DEL-MXP-XXX on AZ (2:50 am departure). All travel in Y.

I won't be present, but I'd like them to have access to some sort of lounge, especially with 3 hours between the two departures. The best idea I could come up with was to buy Jill a 60-day NW WorldClub membership ($85) that would allow access for her and two guests to the Clipper Lounge. Jack and Jill could also use that membership for their layovers in EWR as well as some other domestic travel she has this season. My only worry is that when they arrive at the airport ~9:30pm, Jane won't be able to get a boarding pass from AZ and will be stuck alone outside security.

Is anybody familiar with DEL and can give feedback on this plan?
