Also bear in mind that the MD-83 has fantastic range. No A320, A321 and the older 737s can even come close to its range. I have found in the past that there are alot of great routes just out of range or the Boeing/Airbus narrow bodies. This is where the MD-83 is a gem. She matches alot of medium haul/low capacity routes perectly. In fact the MD83 is a good plane to get fast and expand your network, at the same time you can order the NG737s, which will finally have a similiar range to the MD-83 several years later into the game.
Anyway this is how i feel about the MD-83. In ATB1, my airline was built on the back of these birds. Go the "Mad Dog"!
