It would seem that united.com has some issues with Safari.

I'll be regularly logged out when attempting to do something trivial, like book a flight, or especially when looking at reward flights, and I change the date parameters.

Crashes out with this error:

"! We’re sorry, but united.com was unable to complete your request. Please try later or contact united.com Support in the U.S. and Canada at 1-800-396-1751; the U.K., phone 0800 028 5003; elsewhere use the local phone number."

I've cleared cookies, website data, etc. and as someone who has worked in IT for a very long time, can comfortably say, "It's not my computer."

Anyone else have issues like this?
