Just booked 2 UA awards from US mainland to Hawaii via the phone . Got the confirmation email, credit card was charged for the taxes/fees. However, I was very suprised to find only 25,000 miles were pulled per ticket from my account. Anyone had this happen? Should I expect them to catch it later? Any chance this causes a problem on the day of travel? Or should I be happy I might have gotten a deal and keep my trap shut?
