The browser on my home computer was just upgraded to IE 9, and for some reason DL.com is no longer functional. I called the DL web folks and they said that there were some issues with IE 9, would look into it and get back to me (has been about 2 weeks now).
The main issue I have is that when I'm on the main booking screen/home page, after I enter the airports and dates and hit enter, it clears all the fields and takes me back to the main booking screen/home page. I also have Firefox that I barely use, but for some reason there are no issues when using Firefox (on the same computer). Is there anything I can do so that DL.com will work with IE 9? Should also mention the situation has gotten worse. When I first got IE 9 I could enter the information above, but when I would try to scroll through the results, the results would vanish and I would get a strange statement on the screen. I'd also note that I have not had any problems at all with other websites since getting IE 9.
