Keep the time change in mind as well.
My kid traveled across country and it was a full day of travel. There were direct flights when she started. She really didn’t mind the day of travel because she loved her college!
We supported this because we felt college was a good time to experience a different part of the country (and we could afford this).
Plus, traveling and dealing with flight changes, scheduling flights after exams ended, etc, are skills she still uses. She knows her schedules, how to navigate airports, how to deal with canceled or changed flights, when to look for changes due to weather, and the like.
Good luck to your daughter! Have fun searching and make sure you look at things around the colleges so she sees all that she will be able to do if she is there.
