Can a United Air boarding pass be reprinted if the original one was lost?

A passenger can reprint a United Airlines boarding pass by simply checking in again from a computer or mobile device using United's online check-in service or at an automated kiosk at the airport. The passenger can also ask the gate agent at the departure gate to reprint the boarding pass.

A passenger who received a boarding pass electronically can still use the online check-in service to either get a new boarding pass emailed to her or to open another boarding pass in the web browser of her mobile device. The easiest way to find a reservation online or at an automated kiosk is to write down or otherwise save the confirmation or e-ticket number from United.
