Had a miserable time trying to book a simple domestic flight. I kept getting timed out
immediately and had to log in about 8 times to finish it. Then I could not use my Amex - I don't want to put in my Amex password so I had to use a VISA card. This transaction took
a half hour, when it should have taken 2 minutes. Finally, I tried to send DL a complaint and, though there is NO option to file a complaint about the website experience, I dutifully completed the long form twice, only to have it never go through. It was so frustrating that I almost switched to an AA connection midway.
