Positive experiences
Most of my experience has been with WCs in Chicago, Mem, MSP and just last week, LAX.
If you have had a problem, these people have always seemed willing to help. When I was in ORD on 9/11, just getting into the WC was a good omen. I basically got a car rental reservation via the net and ended up home 12 hours later.If I hadn't gotten into the WC and gotten a hookup onto the net.......
Even in LAX last week, they seemed very willing to assist. I think most of these folks have some experience and that helps.
