I have flown other airlines' 777s and they are truly awesome. In 1997, I boarded one at Kuala Lumpur, Malaysia, using outdoor boarding stairs, so I got a REALLY good look at it. The engines are gargantuan, with 112-inch fans, roughly the same size as a 757 fuselage. Next 777 flight is Air China on May 30. Can't wait to try Delta's one day.
