No no no!

Smoking in commercial passenger aircraft used to require faster circulation and replacement of cabin air. Bannin smoking meant that air could be recirculated less often, thus reducing costs for airlines.

Yes, that's right. Air quality in passenger cabins has actually become worse since they banned smoking.

But on the bright side, we've seen a welcome increase in DVT cases, which apparently are more common with oxygen reduced cabin air.
