I noticed that many folks who posted here seem to favor K over A, and I'm curious about why. Does it have to do with the arrangement of the seat/suite layout, or the fact that most people are right handed? Other reasons? What's your rationale?

My first EK flight is later this year in F. On AS and other U.S. carriers, I'm always a 2A gal when that seat is available. Should I consider switch hitting to the K side for this trip?
