On board the United Airlines 777, I took many pictures of the GPS system that tracked our journey from London to Chicago. Here a few shots to showcase the travel route.
Notes: If you travel in the winter, be prepared for travel delays due to the weather. We left London about 2 hours late due to very heavy fog. In Chicago, my flight to Indianapolis was delayed about three hours due to bad weather.
Give yourself plenty of time to navigate London Heathrow Airport.
United offers a large selection of in-flight movies and music channels that will take a regular headphone plug, so you can use your own, which provide better sound than the airline set.
