Canadian low-cost carrier WestJet has expressed interest in the Boeing 737 Max and is in talks with Boeing on price tags.
The airframer met the airline in late June with a pitch on the re-engined aircraft, WestJet chief executive Gregg Saretsky told Flightglobal in an interview earlier this month. "We are starting to discuss price tags," he added.
"The savings is entirely in the fuel burn which Boeing is saying is in the neighbourhood of 12%, so as long as the price isn't 13% higher, then the math works."
WestJet currently operates Boeing 737 Next Generation narrowbodies, and will have 100 aircraft in its fleet by end-2012. It has existing orders for more than 30 737-700s from 2013 through 2018, although these are likely to be converted to the larger -800s.
Saretsky does not rule out converting WestJet's existing orders for the 737 Max, which will be delivered from 2017 onwards.
"If it was possible, and if the price was attractive, that would be something we would be crazy to not be interested in," he said.
WestJet could grow its 737 fleet to as many as 135 aircraft by end-2018, or keep it as low as 102 if it chooses to return aircraft on leases.
