No bones from this side. It's my domestic airline of choice. Kulula is permanently late, BA is too expensive, and SAA....well the less said the better.
I just speak from a purely objective point of view (albeit mine) in that it seems the equipment is often stopping 1-Time from reaching the levels that their crew and service ethic would allow, if they were operating some more modern airframes.
As an aviator, if you asked me which airline I would expect serviceability issues on, it would unfortunately have to be 1-Time. Perhaps not as result of the MD80 type per se, but there seem to be issues on the maintenance side.
I fully back 1-Time, all the time, I just wish they could attain their rightful place in the hierarchy, which is what their crews, their attitude, and their loyal pax deserve.
