I got a surprise milk run on 768AS in late June after being rerouted from PDX-SEA-JNU to PDX-SEA-ANC-CDV-YAK-JNU. First time on the northern milk run section, second time on 768AS. First flight on it was ANC-JNU on 2005, before it was converted to a combi.
I've also flown on 763AS in regular and combined config, as well as 762AS and 764AS in regular config only, and 765AS only as a combi.
So I guess I can say I've flown on all the combis... in some sense. Anyone else keep track of this kind of stuff for fun? I'm sure many of you frequent fliers on here have easily spent many hours on these planes.
