Don't forget that - if you can make it to AA EXP - you will get 8 eVIP's that are valid for intercontinental First (from any revenue Business class bucket) or for intercontinental Business (from any revenue Economy class bucket) confirmed upgrades - as long as A- or C-class is available, the upgrade is yours. Each eVIP is valid for up to 3 segments (LHR-JFK-MIA-EZE upgrade would just require a single eVIP
).
eVIP's are transferable, so you could give them to anyone...
eVIP's make AA EXP status quite amazing!
