My cousin is in TX and was suppose to fly back home yesterday. She is stuck at the airport till Thursday! Sleeping in the chair there, 50˚ in the waiting area... Nothing is being done/offered by the airlines.
TraneMan, that's unfortunate. If your cousin has been told they won't accommodate them until Thursday, you might want to recommend him/her to move to the city by taking the TRE to Union Station and DART from there. Sitting in an airport chair for two days is no fun, and I believe all hotels around the airport would be packed with passengers, but there are several hotels in northern suburbs accessible by DART, some of them not very expensive, for example, there is a hotel right next to the Galatyn Road DART station advertising $45 rates. It might be a good idea to get a day's rest and head back to the airport tomorrow.
Before someone jumps in with "See this is why Amtrak is so much better than flying" in reply to this, let's put things in perspective. The nasty hail storm that hit DFW Airport put 110 aircraft of American Airliner and American Eagle out of service at once due to hail damage. When you have that large part of the fleet taken away suddenly, there is very little the airline can do about accommodating all the passengers. From what I have personally experienced (with Delta) is that when the flight is cancelled suddenly due to weather, they will try accommodating you elsewhere or give you a full refund of your fare eventually, but that's about it. Apart from that not much anyone can do when twenty thousand irate passengers hound you at once. My sympathies to the travelers stuck, but I wouldn't really blame the airlines for this, just Nature wins against Man.
Edit: I did not notice TraneMan has not mentioned which airport in TX he is talking about, but I assumed DFW.
