Trying to make a flight reservation. After I select the return flights for a return trip, the page "Review Trip Itinerary" shows up as pss.united.com and there is no flight and price info. If I click on Continue to traveler information, I get the following error.

"! In order to protect the privacy and security of your interactions, united.com times out sessions after 20 minutes of inactivity.

This is in Firefox. In Internet Explorer, I don't even get the empty "Review Trip Itinerary" page, I get the error.
