text: Ok I will start by saying I still use this airline because I can't afford not to use them.  I'm an MD Anderson patient that usually flys to Houston from Las Vegas weekly for treatment.  I have missed treatments because of being 4 hours late.  It wouldn't be so bad if they didn't always have a reason to blame it on something or someone other than themselves.  Sometimes the staff is great and other times they are like drill instructors.  One time we were on the tar Mac for 3 hours waiting for a gate.  Another time in the airport waiting for a crew for 7 hours.  The customer service is non existent.
