Furthermore, American Airlines also has the Innovative Solution and Support (IS&S) Cockpit in their 757/767 fleet. They aren't totally converted, so they are flying a mix of the 'classic' and IS&S cockpits. I think they call it the "Maui Conversion". Not sure of the story on that one. I am not sure how many are converted and what the status is of this program considering their Chapter 11 Status.
FWIW, we aren't the only operators of the IS&S cockpit. Airborne Express, CargoJet and ATI all have the conversion.
Regardless, I am looking forward to flying the 767s with whatever cockpit it has.
