I have a flight on Sunday, and am not going to do any better than plain old Mosaic this year. Without the benefit of free EMS, I have no interest in even making sure I achieve that. Since I already booked this flight, I'm in EMS at no additionsl cost. I'd love to change my booking to credit to AA, as I'll be focusing on that now. Do you think I can do that without losing my EMS seat that I already reserved? I have a few more flights in the coming weeks in the same situation.
