First Air will soon be phasing out their two classic 727-100Cs. They will be replaced with two all-passenger 737-200Advs. The YOW-YFB run switches over on Dec 11th, while the YUL-YVP-YFB run goes 732 on Feb 5th. The end of another era in Canadian aviation is nearing.
Not sure what's happening with their 727-200 Combi. I'm guessing it will probably be in an all-cargo config most of the time to replace the lost cargo capacity.
