I just check periodically, but I managed to get to Europe out of Boston and JFK in the last year for under 3000. Once to London and once Paris
our last trip it was right over 3000 and we had two friends going with us who knew that the way it was going to work was they were going to pay the cheap coach fare and then a cheap upgrade and it would cost less than the 3000 we spent. It did cost less than 3000 we spent because there was never a cheap upgrade offered to either one of them ( one of them is platinum and one of them has no status and they checked independently, no upgrades. The one with no status was not happy. The one in platinum knew she rolled the dice and lost. )
