Hello there! I would like to use M&M miles to get an advanced upgrade (C to F) on a LH flight but credit the receiving miles to Aegean's (A3) Miles&Bonus program. Is that possible? How far in advance does LH usually confirm an upgrade if the F cabin looks empty 2-3 weeks prior to departure? Only a few hours before takeoff or long before? In case I receive the upgrade, will I be flying in O class (thereby receiving 0 miles on A3) or will I remain in D class (receiving 200% on A3)...or perhaps even F or A (300% on A3)? Thanks in advance for your input!
