I heard something much more realistic, talking to some people in the Mainline training department. He was saying they were looking at the fleet plans for the new American and he said it did not look good for PDT.
He did say airways wants to keep them around, but they don't want Q400s they want 300's and are having a hard time finding them. He mentioned they hope 300's gain enough interest that they would reopen the 300 line in Canada.
But it's all hearsay of course.
