Re comments on accelerating narrow body deliveries, I don't think either Airbus nor Boeing can deliver A321's and B737-900ER's any faster during 2015 than already scheduled. However the final 36 717's that Southwest (AirTran) parked at year end 2014 and which were planned to enter the Delta fleet at the rate of 3 per month during 2015, will IMHO, have a faster ramp up, with the effort to have all 36 ''up and running'' by end of summer time. The larger classes in January seem to indicate this, and I think we will hear reports of the mods from AirTran 717 to Delta standard MD-95 :-) configuration being accelerated in the next few weeks.
