new issue for me today: (firefox browser)
Took about 5 login attempts before the login stuck.
It now only allows me to search one city pair at a time:
example:
Search LAX-EWR; Look at results.
Then, go to the search box to change it (e.g., change to SFO-EWR); click search.
At this moment, it goes to the error page saying I cannot search for whatever I tried to search and that I should call UA.




Then, I go to the home page and my last attempted search is still under the Book Flights tab.
Whatever.
(ETA - I have tried about 15 different times this morning...and the same thing keeps happening).
The website is simply awful with respect to simple functionality.
