Dec. 21 2015, ©. Leeham Co: Last week we started our Boeing 767-300ER article series around acquiring used twin-aisle 767 aircraft to upgrade 757-based long haul services, like Canada’s WestJet has done. We compared the aircraft and looked at the base data for the aircraft in article one.

Now we continue by analyzing the Cash Operating Cost (COC) of the aircraft in a typical long haul configuration, using our normalized seating. We are assuming that the 767 and the 757 are a half-life state between overhauls of engines and airframe.

Our benchmark aircraft is an Airbus A330-200 which is flying in a mainline airline. Here we assume that it is 25% deteriorated since new for engines and airframe.


  • The 767-300ER and A330-200 differ in fuel and crew costs per seat mile but are close in most other cost items for COC.
  • The 757-200W has lower fuel operating and crew costs than a 767 for the sectors it can perform. It is more expensive in maintenance and landing/underway fees on a per-seat basis.
  • Overall the 767 is sufficiently within range of the A330-200 for cash operating costs so that when we add capital costs, it could be close to a draw.
  • Finally, we will look at the earnings capabilities of the aircraft by adding standard yields for the payloads the aircraft can carry.
