I have a trip booked for two of us both gold in October for which I have applied to upgrade from economy using miles.the itinery is:
LGW/DFW/SEA (stopover w/end in Seattle) mileage u/g applied for
SEA/ATL u/g using stickers applied for
ATL/DFW mileage u/g applied for
DFW/Lgw mileage u/g applied for
My reservation on AA.com disappeared for 3/4 days today it has re-appeared & the leg ATL/DFW now shows as first with unassigned seating everything else remains in cabin. Now the question:is AA.com playing fast & loose with me since mileage for transatlantic u/g is 25K miles from ATL & 15K? miles for an internal flight ATL/DFW. on which I could use stickers. Has anyone any experience of this sort of situation?

Thanks
