Assuming at least 50 737-700 aircraft were in any subfleet to spread any extra fixed costs, and allowing for an average 1,100 km bog standard route flown 6 times per day, standard depreciation, and equivalent discount from list price what's the approximate difference in total cost per year of buying, fueling, crewing, maintaining and operating a 737-700 compared to a 737-800 ? How much reliance is currently placed on absolute interchangeability of aircraft that would be partly lost with the existence of a second type ?
Or to put it another way, how big an impact would an additional but slightly smaller aircraft really make to Ryanair ?
