Even The Air is Better in First Class on This Airline

First class passengers need not rely on their air of superiority because they're breathing superior air — at least on German airline Lufthansa.
The airline recently installed humidifiers in the first class of its Airbus A380s, bringing air quality up to par with the luxurious lie-flat seats and other services available in the premium section of the aircraft.
"[The humidifier] gives a totally different experience," Lufthansa chairman and CEO Carsten Spohr told The Times of India last month. "Passengers arrive in a much better shape after a long-haul flight."
