A single ex-KHA DC9-10, I believe, N112PS unless they've acquired more. Saw it a few months back in Toluca and, believe it or not, Del Rio. Mostly Lears and Shorts, scheduled and on-demand, based in ISM. Talked to a Shorts crew in Windsor a few weeks ago. They echoed the normal aches and pains of 135 freight, nothing drastic bad or good.
