We're in the business of making money by haulin' stuff (breathing or otherwise) in Aeroplanes, Don.
Your beast does that very well on some routes, ours on others.
Still, it's interesting that your "Modern" aircraft has, depending on how you do the math, either a slightly better or slightly worse fuel-burn per KG/RPK/Bum-On-Seat or whatever than our "old" one.
How will it compare to an aircraft with a 20% better performance?
