Just returned from LAX on QF94. Had requested upgrade from Yflex to J using points and had been anxiously checking for success during final 48 hours leading up to flight. No joy T-6, but did the usual request for pity at check-in only to be told the flight was very full and there were no upgrades available. Consoled myself with food and bev in the QF lounge, which is fantastic compared to the previous version although still not a patch on Singapore. On approaching the boarding gate was still holding out hope of the upgrade. My boarding pass was greeted with red flashing lights (the computer says NO) and I was directed to the service desk where I got the good news - J it was. The curious things is that there seemed to be a good 20 plus people doing the same thing. That's a fair chunk of the J class seats coming from at gate upgrades, so how come they suddenly appeared in the hour or so between check in and boarding? Oversold Y causing a cascade of Y to PE, PE to J, J to F upgrades or something else? Would be a bit annoyed if I was NB or PS and hadn't got the lounge access (but then they may have had little chance of the upgrade anyway). Sorry for the long and somewhat trivial post, but interested in any responses from the learned QFFers. Thanks, Mike
