Also as a reminder we have added a calendar to the United MEC website.  This Flight Attendant Calendar lists important dates that Flight Attendants may need to refer to including but not limited to: Vacation Bidding, Benefits Open Enrollment and other dates throughout the year.  If you are a Google Calendar user, you can add these events directly to your personal calendar. The calendar from the home page of the MEC website on the "Quick Hits" menu or the "Flight Attendant Calendar" button below the menu on the left side of the home page.
