I'm wondering what chances do I have for an upgrade for a tomorrow AA179 JFK/SFO. I looked seats availability and it shows 3 seats are available. I'm only Gold and requested an upgrade on stickers. I've been put on the upgrade stand-by list. Do I understand correctly that EXP and PL requested upgrades should've been cleared by now? I bought the ticket back in November and requested an upgrade at the time of booking, so does it mean I have a chance to be high on the list or are there other variable that come in play prior to the flight? Thanks.
