What is really interesting here is that ACA based in IAD hit up JetBlue to operate as JetBlue Express 6 months ago to fill their larger airbuses, but JetBlue said no thanks as long as UAL is around. Now in a surprise turn of events JB decides to take the idea and run with it. I think as long as JetBlue keeps the unions out they will grow. As long as the upgrade is less than 2 years to A320 captain, they will have no problems keeping the pilots happy. This is not a wise move in my opinion to add smaller planes that have not had all the bugs worked out of them. Look at Dornier, where are they now? I doubt Jetblue will be able to successfully fly these smaller jet compared to USAir's competition. But then who thought they would be able to fly brand new busses and make money.
