bmi can't hide from the CAA Statistics.
Passengers Carried on the Airbus fleet (A319/20/21/30):
February 2005 432,452
February 2006 374,068 (down 13.5%)
January 2005 449,197
January 2006 385,048 (down 14.3%)
December 2004 481,873
December 2005 433,836 (down 10.0%)
(Edit: Lucifer beat me to it, but you will notice bmi have cleverly pursuaded the CAA to combine all it's passenger statistics under the "BMI GROUP" of late, making it impossible to provide a proper year-on-year comparison for bmi 'mainline' numbers as the latest stats are lumped in with regional and baby. Looking at the passengers carried by aircraft type is the only way to do it)
