Re: DL retiring MD-80/90s quickly

I guess it just makes sense. The main advantages that the MD-90 has over the 80/88 is capacity and fuel efficiency. With the load factors in the single digits these days, the capacity is moot. With fuel prices in the tank, and with the substantially reduced loads in the planes, the fuel COST numbers...
