Thanks AutoSlash. Two more questions. First, it that was hard for me to figure out on the website. Is there a fee to 'redeposit' points for award tickets that are flex and cancelled? Second, if I'm mosaic, and I want to change 24 hour in advance for no fee, do I still have to pay fare difference? Or if there is any open seat, I can move to that?
The latter would be a pretty good deal for the regional jet routes, since you are not worried about getting stuck in a middle seat...
