Possible to upgrade PVR-SFO flights for less?
I am trying to upgrade my flight from Puerto Vallarta to Sfo with miles but United wants to charge me 30,000 miles and $1000 dollars for me and my wife. I could have bought a roundtrip first class ticket for less then that. What's wrong with United, i am thinking about canceling my mileage plus and never flying with them again any advice? Any info would help. Thanks
