I'm just about to go on a rampage because of this utter POS of a website.

Seriously, is somebody at united.com actively sabotaging this hunk of crap for their own entertainment?? Daewoos and tiki huts have to be constructed more soundly than this e-commerce disaster. Zit-faced, computer geek teenagers surely could build a more reliable site.
(1) Selecting "flexible dates" is nice, but it eliminates the schedule and multi-city search modes. Deselecting "flexible dates" does the trick, but only for one search. On the second search, it seems to select itself...
(2) Sometimes the drop-down price box (in schedule mode) shows up, sometimes it doesn't.
(3) Dates in multi-city mode...we can just say that they are never saved, and each time I do another search, I HAVE TO RE-ENTER THEM.

Doesn't help that it defaults to flipping January 2008, either!!!!!!
(4) Why don't they just pull off the time of day filter??? They're not fooling anybody -- this dropdown is clearly there because all other airlines have it. Only difference is, on other airlines' sites...it actually filters flights as expected. On united.com, it just...actually, I really don't know WTH it does!!!!!!!!!!!!!!
I cannot believe United's management. When they put the company in the toilet for good, it's probably a good idea to not mention their most recent employer on their resumes...I wouldn't let a former UA VP scrape bubble gum off my shoe.
