PHL-MCO on an A321 with 20F has steadily been dropping. $185 2 weeks ago an $140 in the week leading up to the flight. It's 2 days from now and EF shows J7 and seat map 10 open. it was 12 open seats yesterday when my PPRO window opened. no upgrade. Today the PLT window passed and still no upgrades. They really want to draw it out until the last minute for those buy-ups. I can't think of any other reason to leave so many open. The Y seat map has a lot of MCE seats open too, so I don't think there are a ton of elites on board as it is.
