I find myself 472 miles short of the 20K miles I need in A3's MilesAndBonus program to make Star Alliance Gold. I assume I'll have to fly someone, somewhere to get these miles. The only travel I have currently scheduled is a seven-segment award trip this summer on AC / EVA / TG. I'll list my A3 number on all flights (to get my lowly Star Silver benefits). Any chance one of these segments might accidentally credit miles? Does anyone know any clever way to get those 472 miles without having to make a special flight to do so?
