I think that SW and all the other airlines are holding thier breath waiting to see what happens. If common sense breaks out and Americans realize that NOTHING actually happened and continue to buy tickets then the airlines are happy.
However, if Americans back off on flying then SW will probably release a systemwide sale. So just give it a little while to average out
Dings are not related to yesterday's non-event, but are related to sales of tickets. If SW is expecting to have to do the sale, they may just wait and do that as opposed to the Dings.
