I'm flying out tomorrow on UA and when I went to do online check-in I noticed that our travel agent put my MP# on the ticket and not my US# that I consolidate most miles with. What is the easiest and quickest way to get that corrected. I tried online, but UA.com doesn't let you make those changes. Don't want to waste an hour in line at the airport or an hour on the phone if I can avoid it.
