Darcie,
You can call the Patient Travel Services at Rochester 866-551-3392 and be ready with your patient account number. Also check out the web page Mayoclinic.org and tab on Care at Mayo Clinic, then Patient Visitor Guide. Fill out the request form. No guarantees.
I see where you are located. Small aircraft usually won't do mountain flying in the winter which leaves us with jet service only. Angelflightswest for your district doesn't go east past Montana. There are other organizations out there other than Angel Flights. We have one here in the Midwest which I participate with.
