I can't speak about other airlines, but in a few months, Alaska Airlines will have been operating the 737Combi for 20 years. I think they have 9 now and just recently added the latest. When I was there we'd "recon" planes in Anchorage all day and night. At peak times one airplane would be reconfigured 4 times a day depending on passenger and cargo loads. The 727QCs were harder to do, but Alaska used them right up to the end of the type in service. Mike > I recall that B727/737 QC's never were successful. To much trouble/time to change every day and every night like the oiriginal idea was. Didnt UAL and other give up on them pretty quickly? > Dennis >
