HI, I was looking at option flying AA on award travel. First I reviewed miles and taxes. Found that flying AA direct not on partners like BA result in significant taxes. There are approximately 11 cities AA flies into that result in only $5-$7.50 tax in addition to 20K milesaver award mileage. However, nothing is available flying Seattle-Frankfurt for 20K award just 60K for coach which I checked from Oct 2013-May 2014.. Anyone know why? AA told me that 20k award is eligible not unsure why no availability.
