United Airlines' first Boeing 787-10 Dreamliner has begun regular service, flying between Los Angeles International Airport and Newark Liberty International Airport. United is the first carrier in the world to operate all three Dreamliner models, including the 787-8, 787-9 and now the longest model, the 787-10. The Dreamliner's entry into scheduled service continues United's comprehensive fleet plan, while providing an improved experience for customers. The aircraft is United's first Dreamliner model delivered with the airline's signature Polaris business class seats, and new United Premium Plus seats. According to the carrier, Boeing's Dreamliners are known for “dramatically improving the onboard experience for customers” with lower cabin altitude, better humidity, cleaner air, a smoother ride and better sound quality. United expects its second Dreamliner to enter service between its hubs in San Francisco and New York/Newark in February, and to begin international service in March.
