Just a story I thought I'd share... Back on 6/11 I flew an RDU-IAD leg on the originating flight of the day (a Republic Q400). I was next on the upgrade list right up until time of departure, and 2D showed as available right up until departure. I took my seat (second row of E+) with clear view of the galley and flight deck. Throughout boarding there was a woman leaning into the flightdeck, chatty with the pilots and flight attendant all through the boarding process. It wasn't until the boarding door closed that she said "Oh great, thanks!" and sat in 2D. Ironically, when I arrived in IAD and turned my phone on, I found that I had been upgraded on that flight. UA has since refunded my $14 E+ fee, and my flight history shows that I flew Z class (consistent with an upgrade) on that leg, despite the fact that I was in my usual 4C seat. I have a sneaky suspicion that they processed my upgrade, but instead of telling me, the flight attendant gave it to her friend. Now it's only a 70 minute flight, so F isn't all that big of a deal. But the fact that I appear to have missed out on an upgrade given how horrible Silver upgrade percentages are, sort of torques me off.
