FlyBe is a model I'd suggest ANZ will be looking closely at.
They're getting out of 146-300's and into ERJ-195's, on top of a big, and growing quickly, fleet of Q400's. They have reported plans of introducing QX once available.
Checking scheds they operate 195/Q400's on identical routes. Jets at peak times, Q400 off-peak.
With airfares of $0.19 and a hoard of competitors, they're claiming they have the fleet type to succeed. Seems they do! Though when your competitors drive J41's and Saab2000's ...
As for ANZ, the unfactored is of course what will become of the 733 fleet. With 120 odd high density in the 195, one might suggest that it will be a suitable type. It has certainly got the legs, if needed, trans-tasman.
My thought is MCA will operate the Q400/QX fleet - 11? - the ERJ's get operated by the 733 team?
Over/out
PS: No-ones suggested 737-600 with optional winglets. Stick to what ya know??
Na, thought not.
