Gnd Power, don't get me wrong the A320 is an excellent aircraft and way better than the EMB-170, which is to this day, grab bag expensive to run 70seater.
What I am trying to say is what you summed up on your last sentance.
BTW, the Solomons certainly like change dont't they, in the space of 2 years or so they have had the Spanish, SAW, OJ, OA and are now off to Strategic.
What makes you think the A320 operation would work?
