The company fly as many 50 seaters as they want according to the scope clause; hence exactly 50 seats. Certainly an interesting end-around on their part.Yeah, I saw that. It's an interesting experiment in small passenger jet flying. The concept seems a bit like how the ER 175 has turned out- in the sense of a tube that could fit more seats, so the seats can be more spread out and more comfortable. The number of seats in the 175 is limited by scope but the number in this 550 will be limited by choice.
