I booked a trip this week to fly to Beijing and back home out of Shanghai. I just realized the two flights are a "longest" of some type. Detroit - Beijing on Delta is the longest scheduled A330-200 route in the world. 6,631 miles. Shanghai - Detroit on Delta, currently a 777-200LR but will be a 747-400 when I fly in April, is the longest nonstop flight operating in/out of Detroit. 7,137 miles. I was hoping to book through Chicago where American is operating the 787 to both Beijing and Shanghai, but it didn't work out. Should I make sure all of my affairs are in order before boarding the Airbus?
