Sort of off topic, but Website Usability is a big thing.. I noticed DL is redisgning their web site. I like UA's new site, but everyone (airlines webmasters, specifically)should read a book I just picked up at Amazon.com. It's called Designing Web Usability
http://www.amazon.com/exec/obidos/ASIN/156205810X/. If more airline webmasters read this book, it would make it much easier for me to purchase tickets online!
