A bunch of us are going to Vegas from December 26th thru January 5th. I'm flying out of CLE on United because I have upgrades. A couple of friends are flying out of CLE on Southwest. They asked me today if they should buy their tickets now or wait....I have no clue as I don't fly SW. Can someone give me advice so that I can forward this advice onto my friends. They are thinking ticket prices may drop...I'm not familiar enough with SW to advise them. Thanks.
