Use the 4 eVIPs for two upgraded (from coach) round trips to Europe and that'll get you an additional nearly 50K miles total (including the 100% PLT/EXP bonus but no bonus for the upgrade). That's 50K closer to 5MM
My travels are almost always international and so I always use my VIPOWs to get miles that I then use for awards for friends & relatives who cannot afford to travel much.
How long did it take you to get your 4 eVIPs for your 4MM? I crossed 4 MM early last month and have not received mine yet.
Being an EXP is like owning a Perpetual Mileage Machine; for each paid trip I take I get another 25K miles which is good for a free domestic/Canada/Mexico trip
