You can email a trip, including all the flights in it, on the My Trips page or the Trip Details page. On My Trips, click on the 'Action' drop-down menu next to the trip you want to email and select, 'Share'. This will trigger your email client to open showing a message that's been pre-populated with the selected flight details. Then you can enter the email address(es) to which you want the information sent. Or on the Trip Details page, click on the envelop icon in the top right corner of the page where it says 'Share my trip'. This action will also trigger your email client to open showing a message that's been pre-populated with the selected flight details, where you can enter the target email address(es).
