One more hint: Be sure to check out the SeatGuru (www.seatguru.com), which I find to be an indispensable resource for finding the best/worst seats on a given aircraft. As was pointed out previously, your return flights on 2/15 are actually on Lufthansa, so be sure to consider that when lookup up the approprate seatmap.

Barring an upgrade, another investment to consider would be a pair of Bose noise-reduction headphones ($299). Close your eyes, and you'll be in musical heaven; the next best thing to scoring an upgrade is forgetting that you're in coach!
