I'm not sure if I can use it to pick up groceries or if they have to be delivered. I would honestly prefer to pick it up most of the time. I would just use it for normal grocery items I woild buy anyways(eggs, milk, cheese, etc)

The $5 doordash credit I use every 3 months once it builds up to the $15 limit.

I wish I had known about the airport food thing. I've used the priority pass lounges a few times but in general I avoid layovers, don't get to the airport early, or don't use airports with a priority pass lounge to use, so it's been a while.
