Ask on Nextdoor about a ride. At least in my suburban area there are a few go-to Uber drivers who are willing to store a car seat and bring it to pick up. For your stroller, you will have it tagged at the gate. If you want to put it in a bag, it's up to you. Leave it folded plane side and it should be brought to you at the gate when you land. Same for the car seat if you don't use it on the flight. You can check it in as baggage too like the pack n play.
