I'm hoping to have a trip home at some point in the not too distant future and it absolutely burns me up that I have to use United / Air New Zealand again. I got Steve a United Mileage Plus number before we flew to Australia in March 2007 and to this date, after numerous phone calls, emails and written letters of complaint, United has still not credited Steve with his miles. They didn't even send a response to my written complaint, and I've rung them from New Zealand and been on the phone for half an hour trying to sort things. He's owed over 10,000 miles and they've just blown us off, again and again, despite the fact that he was in a booking class which did leave him eligible for those miles per United and Air New Zealand's guidelines. I can't wait until they open up the route and Virgin is a competitor!
And if that wasn't enough to keep you from choosing United, how about the fact that they've just grounded a few of their planes due to maintenance issues. Seems the firm they've outsourced their maintenance to isn't keeping up with FAA standards.
