Hi @annamom. I’m not sure where you’re flying in from, or how long you need to get to and from the airport. We drove from OOS in the morning as UA was the first of a few college campus visits. We had a full day at UA planned. We had a 1pm tour, ran roughly 1 1/2 - 2 hours, followed by about a 20 minute group info session with an admissions counselor. We also had an honors college 1:1 session and a meeting with a department head. It was a long but thorough day.
Check the tour and info times on the website, with a morning tour you could be fine with an early evening flight. It’s a big campus, I’d allot 3-4 hours for tours, info and walking around, book store, observing the activity on the quad, between classes etc. That’s to get a total view.
Hope that helps. Good luck and safe travels!
