I read a number of scientific journals and magazines, but (un)fortunately Parade Magazine is not one of these. It would be strongly suggested you gather a few more facts before you begin protesting too loudly. For a starter, you should better define the units you quote......it would help us in the bleachers better understand the "problem" prior to getting a satisfactory solution (ps: it is probably cfm/passenger). I general, I totally agree aircraft air is very crappy, but so is most office air. In fact the outdoors in general aint too great in and near most large cities (and I often cough just walking by the front entrances of most office buildings with their hoards of happy puffers).

Should you wish to bone up on this airy subject, I suggest this article to start with: http://www.boeing.com/commercial/cabinair/ecs.pdf . Good luck.
