I'd love to see it broken out apples for apples. For example, on JFK-LAX, AA spends $X, and DL spends $Y.
AA's route mix is different from DL's.
I wonder if that takes into account routes where no food at all is served? i.e. do those routes count for $0, and then divide by total number of pax? If so, keep in mind that DL has DelEx, which produces lots of pax but has relatively low food costs.
