Gah! I booked a United Vacations flight and hotel package. The receipt they e-mailed me has my correct name, but when I go into My Itineraries to look at the flight, they've tacked my middle initial onto the end of my first name. I just called UA about a seat assignment I couldn't change online and also mentioned this issue, and they bounced me over to UA Vacations, which was closed. I'm thinking I really ought to get this fixed, though -- I'd hate to find out at security that I can't get through.
