I have a good one re us air. I booked coach in April for oct AMA cruise. I always use miles to upgrade. No more. I called every two weeks to see when availability would open up, kept being told not yet. Then, after two weeks again, all available upgrades were gone! Next day, I checked again and the whole business class section. N was full. Every time I checked, I actually talked to a person! Then there rules have changed in the two years, so now, on USAir, upgrades are now per segment, not by trip. So to get to Budapest, it takes three segments, and I would have had to upgrade three segments in each direction !! How ridiculous is that..
The good news is I had bought a fully refundable ticket, so I f
Didn't lose anything, confirmed with Delta that the fully honor Orbitz rates, and am now fully booked in business class (cash) for only $200 more than USAir using miles and money to upgrade!,,,
