Flying JFK to JNB early August. Am upgraded to F for the second flight but anticipate, if there is space, not getting an upgrade till the last moment. My account has enough miles for the upgrade if given for the whole trip (ie 87,750 from business saver). My DXB - JNB leg 'cost' 46,800 miles. When upgrading on line I've got the total mileage has been correctly recalculated and wonder if this will also be the case if I can't upgrade until the day I fly or whether I'll have to submit more miles for two separate legs.
