This was one of the topics on the Mandy Connell  (Colorado) radio show  yesterday. Where a caller said:  "It used to be when People traveling on the airlines used to dress up to catch a plane,but now what we see ,is people catching the plane using T-shirts ,Shorts. "Hot Pants" and even Pajamas".  "priceless or......Classless?
So True! And BTW, like any business,,the Airlines reserves the right to refuse service to anyone,if they cannot comply with a simple dress code.

 But what really gets me, is when you see these "Cheapskates"travelers trying to shove an OVER sized luggage into the overhead compartment!  uuuuuuuggghhh! Really? This one really get's me.IMUA
