yepp,
you can increase the pax number every year and in the same time lower the av. fares by 15%, but how long? Until you carry 200 million pax/year completely for free :-)
Total revenue per pax is declining since 2 years: last year by 11%, in 2009 by 6%. That's the only thing counts: revenue/pax.
I know they have terrific success in the past, but in the future they need some fine tuning.
