Delta has no plans for a 100 seat jet so I think the issue is moot. They always act like they want a 100 seat jet around contract time but thats happened now for 20 years since the DC9's were retired with no replacement. Last 100 seat purchase was in 1983 with last delivery in 1985. The jets announced in the fall will all be large narrow bodies. Nothing smaller then a A320 or 737-800. AvWeek reports that Airbus has a shortage of A320 orders in the 2014 to 17 time frame and may be willing to give out huge discounts for orders then. Same time frame we want a bunch of jets.
