I re-read the posts and I think two posts are contradicting. Narrowbodies have higher CASKs or vice widebodies?
It depends on the labor supply behaviour of the country/company being looked at.
Here, the crew cost component between narrowbody and widebody aircraft per seat is generally equal.
Then we go to the configuration of the aircraft.
At max capacity CASK will be slightly cheaper on the narrowbody.
On single class non-sardine can, CASK will be cheaper on narrowbody.
On multi-class, it depends if they use the same seat pitches or not, if yes, it's equal if not cheaper on widebodies... if not, then it can make the narrowbodies cheaper.
Maintenance also depends. Basic consumable line maintenance effect on the CASK is cheaper on widebodies... BUT, once you go "full maintenance costing" for, say, 10 yrs (past and budgeted), then it can quickly make the narrowbody much cheaper on a CASK basis.
So, it all depends on what you're looking at, what cost behaviours you want to exploit in the analysis, etc...
My Post #5 is based on LCC configs based from what I know/seen... but where the widebodies are used for the range, not for the cram as many people in on a single trip...
