Hehehee hhaahahahahahahaa ahohohohoooo! [and more crazed laughter].
PSA getting jets? US mainline can't hold on to their existing jets, and the rumor is they're buying jets for PSA? No, since all the action is going to Chautauqua, Mesa, et al, PSA will likely never get jets of any size, shape, or form unless:
A. they get them dirt cheap, or someone else buys them, or
B. all the turboprops are gone from the Express system and they must bow to the inevitable
Neither of these scenarios is going to happen within the next 5 to 10 years, so it just isn't a factor. Sorry.
