Hi I am flying into American airlines and will arrive at 10:00 p.m. wondering if I'm able to get an Uber that late at the airport?

Positive that you'd be able too

Yes you can

Pre order

Yes you can, you also can schedule a pickup with them.

Shouldn't be an issue. Got in at 2 AM in the middle of the week and was able to get one

I don't believe they allow people to schedule rides from O'Hare airport. The drivers have to just sit in a waiting area and then once you arrive at baggage claim or somewhere you can request a ride. But the app would not allow me to schedule a ride
