You're comparing apples and oranges, BA don't fly the same aircraft type as FR, they fly a wide variety, some smaller and some bigger. BA might well carry 40% of the number of passengers that FR carry but the chances are the average BA passengers will have (gladly) paid more for their seat than the average FR passenger will pay or will expect to pay.
In 12 months to March 2002 Ryanair carried 11 Million Passengers, BA carried 40 Million, now BA carries 32 million and Ryanair carries 73 Million.
Yup coming Ryanair with BA is unfair
