A successful C100/300 gives DAL the ability to bypass hubs in thinner markets at vastly improved economics. It will have 2x the range of the 717. Think pairings like SEA/STL, LAX/HOU, LAX/DAL, LGA/IAH, SFO/SAT and many more. It will be a game changer for DAL structure. The 717 will continue to shoulder the shrinking regional routes in and out of hubs. Cue Bowie singing "Changes".
