Could 'widebody' passenger planes end jet lag?

Jet lag starts to creep up on travelers once the plane hits altitudes above 6,500 feet. However, two new wide-body airplanes, the Boeing 787 Dreamliner and the Airbus A350, may have cracked the code to stopping this phenomenon. These commercial airliners are designed with plastics in the airframe, allowing the cabin to stay pressurized at 6,000 feet - no matter how high the plane flies. (www.dailymail.co.uk) Plus d'info...
