PRIVATEAIR operates DUS-EWR for Lifthansa with a 737-700. It has all business seating for 40 passengers. The success of this has expanded this "subcontracting" of Lufthansa service for DUS-ORD & MUC-ORD. This type of nonstop all business flights should develop nicely in he coming years as Club Class passengers willing to pay $5000 for flights avoid the crowds and get their faster. It''s like a concept of the Concorde at economics that make sense. The flight is the same speed but if you get the experience of a private jet and no crowds.
