I recently purchased (with money) (to fly in a couple of months) BCN-PHL in PE, returning PHL-BCN in business, AA tickets, bought on AA (Europe/Amadeus) website, all on AA metal.
I don't see any place/option to upgrade, not with miles, not with money, not bidding; not in the app, not on the website. Not on the US locale of the AA website, not on the .ES locale. Not in Change Your Trip ("this trip cannot be changed online. call to change your trip"), not on the seat map, ...
Are some AA fares NOT upgradeable? Or is my advance, largely-discounted fare something that AA isn't interested in letting me offer to upgrade .. yet?
How does paying to upgrade already purchased-and-ticketed itineraries work these days?
thanks,
