The -900 doesn't go senior. Nobody I've talked to likes it, except the passengers ... who are starting to complain about the weather that the airplane can't avoid at the altitudes it operates in. The -700 is a much better airplane.
It would be hard to bid around the the -900, but it wont be "senior."
