I agree with PIA777 and Asianguy767. I think the 717 would be a perfect fit into that area. Customer satisfaction on the 717 is also very high, or so I have heard. I think it would be great to maybe see a 717/73G joint order!
Some airlines are thrilled to death, but I can think of several JetStar birds that have been traded and repainted more than a dozen times in 5 years.
The points made above notwithstanding, there hasn't been a single order lately where the size is completely out of proportion to the resources of the airline which has not gone to Airbus.
I wouldn't go that far. Boeing has scored many coups this year, very few of us thought Air NZ
would order the 777s and 7E7s and the First Choice/Blue Panorama has exceeded the resources of the airlines, in some people's opinion.
