Delta may order up to 200 aircraft, as it looks to replace aging aircraft
The company said that it had asked for proposals to deliver 100 to 200 firm aircraft, with an option for 200 more, starting in early 2013. It said possible orders could include large, medium and small single-aisle planes to be used on U.S. routes.
I guess the replacements will be for A320s, DC-9-50s, MD-80s and 757s
