From UA’s United Hub website:
During our 787 Dreamliner First Look event at Boeing’s Paine Field in early August, we held a TweetChat that generated a number of great questions from our customers. The topic that came up the most was destinations. People wanted to know what cities our new Boeing 787 Dreamliner would service. We’re excited to give you answers about the first international routes for our new aircraft.
We’ll kick off our 787 international routes on December 4, with service between our Houston hub and Amsterdam. This route will be offered through March 29, 2013.
Next up is service between Los Angeles and Tokyo, with daily flights beginning on January 3, 2013, followed by nonstop service five days a week between Houston and Lagos, Nigeria, starting on January 7.
From February 4 to March 29, our 787 will fly between Houston and London Heathrow.
On March 30, we will operate flights between Los Angeles and Shanghai, and on March 31 we launch our Denver-to-Tokyo route, which we announced previously.
Our flights between Denver and Narita are available for sale on united.com, and you can book our newly announced flights beginning on August 25.
Closer to home, we’ll be announcing our 787 U.S. domestic routes, which will launch before our Dreamliner takes off to international destinations.
