From airlineapps FWIW

"Thank you for your interest in United Airlines. We plan to be hiring pilots in the fourth quarter of 2012 and in to 2013. In preparation for this hiring, we are updating our application and addendum to better reflect post merger requirements. These changes are nearly complete and we expect to start reviewing applications in the coming week.

Please make sure your United (previously Continental) application in Airline Apps is up to date and check back regularly for any announcements regarding application changes."
