Success (or Not) Upgrade Main Cabin / MCE to Premium Economy; How, Details
Though AA has no current clear upgrade path from Main Cabin or Main Cabin Extra to Premium Economy (most likely forthcoming once PE is rolled out to every AA widebody aircraft), there has been discussion of upgrade success, etc. from the Main Cabin to Premium Economy.
Please share your MC/MCE to PE upgrade success (or unsuccessful attempt to do so) here, including your status, method of upgrade (op up, online seat map choice, 500 mile “stickers” / Unlimited Domestic Upgrade, LFBU / Load Factor Based Upgrade and how offered) etc.
