I'm also IAH based and have been looking for another airline to give my business. My most frequented route is IAH-EWR and unfortunately that makes it doubly hard to leave UA. After having one too many maintenance issues I decided recently to switch to DL and start flying to EWR with a stop... Not ideal, but less stress in my mind than worrying about all these maintenance and crew issues. I also chose DL over AA because I value a strong alliance network in Europe and Skyteam was more appealing to me than OneWorld. Hope this helps, see you at terminal A
