As I type this from
#1 on the upgrade list in E+ on an a319, the United fleet site shows "Starting Fall 19 Reconfig to 12/36/78," and the a320 "Starting in '20 Reconfig to 16/39/95." After some googling, I can't find a source, but I personally consider that a good move, especially since F is often consistently booked full on the 319s. I'd like to hear opinions from others, and a source if possible.
