Other enhancements include installing broadband Wi-Fi on more than 200 planes and streaming wireless video on its 747-400 aircraft.

The product changes are in addition to the 25 new aircraft, including the Boeing 787 Dreamliner, that United Continental will introduce to its fleet next year, the airline said.
