This is certainly a good move but I don't know how much A+ Elite flyers will be able to benefit from it, at least on the routes I frequent. I've always made a point to show my elite card when boarding and then ask if there were any seats remaining up front for an "unofficial" comp upgrade. Up until a few months ago, this worked about 75% of the time.

Then, once FL started selling upgrades as a part of the online check-in process, the answer soon became "sorry, Business Class is full" almost 100% of the time. Good for FL, bad for those of us not willing to shell out the $49!
