there is some sort of issue from canada i see. you can reach united.com using ie, but sign in never completes. firefox on united.com just pukes with a message about a redirect that will never complete, and i see the browser bouncing back and forth from united.ca to united.com

what i find works for me from canada is manually going to pss.united.com, i can sign in no problem that way. united.com doesnt work. united.ca doesnt work.
