I have my real doubts about its continued operation to GRJ, its not about the aircraft but rather the competition. Like it or not the pax still like jet over TP so with BA and CE operating jets I can see any advantage for SAX as they will have to lower prices over time to attract the traffic.
I dont know what the guys at SAX are up to-to me I would keep this aircraft on BFN- period. I see it does some sectors as does the F28, now why send the F28 to BFN in the morning when you can send it to GRJ instead?? Send the Q400 to BFN will make you more cash out of the same traffic.
