hope everything works out for you at the Mayo.

how far do you live from TUL?

northwest has some good prices for okc/rst out and rst/tul on the return

just something to consider, since the schedules to OKC and TUL may suit your needs differently for the days out outbound and return.

you didn't make it clear but I assume you were looking at tickets to RST. You could also look for tickets to MSP, and then either rent a car or take a limo/whatever to Rochester. I can't quote you a price but can recommend these guys Aspen Limousine Service 1.888.MN.ASPEN | 952.405.8400 | 651.429.9876

it's about 90 miles driving from MSP to the mayo clinic, and as many minutes. this might be a faster option for you than waiting for a connecting flight, and could be a nice time of year for a drive - falls colors should be near their peak.

here's what the Mayo has on their web site
