One of the quietest flights I have ever taken. I'm not sure if it was because there were few children on the flight or what, but it was quiet from DFW to Tokyo. The flight attendants were very accommodating, as a very large man was seated next to me and looked very uncomfortable. There was a seat in the bulk and he agreed to move there. Thank goodness as flying for 13 hrs would have been stressful for both of us.
