Just food for thought:
FedEx to Buy as Many as 100 Boeing 767 Freighters - WSJ
What's efficient for airlines operating the 767 in years 2015+ is that even though more maintenance may be required, im sure the parts are relatively cheaper than say a new 777F. (like comparing a 2001 car model part versus a 2015).
A note on Westjet deviating from the Southwest model - Canada (35 million people) simply doesn't have a strong enough national population like the United States (318 million people) to sustain a southwest model which is based on low fares and high load capacities ((compare NYC-LAX (excluding nearby airports) about 40 flights a day, YYZ-YVR about 28)).
Any airline in Canada needs to tap into the international market to survive. Even Porter has invested into C Series to tap into the US and sun destination market. Air Transat also with their 737 can now utilize their A330 and A310's to provide greater flight frequency to Europe as well. Nice to see the steady growth for Canadian air travel!!
