Shipping to NHC Finals

I have two beers that I am shipping to the NHC finals in Portland. I have decided on doing two-day shipping by UPS. I have three questions. Will this involve an airplane? If so, is the cabin pressurized? Any other thoughts or recommendations I should consider?
Thank you for your assistance!

P.S. I hate that I can’t tell them it’s home brew for a competition. It would be much better if I can go to UPS directly for their assistance.

Two day shipping guarantees an airplane, driving from Cedar Falls to Portland would take quite a bit.  Cargo planes are pressurized like commercial planes.
