Qatar joins Oneworld in about five minutes.

Oneworld ups its game.

Unless, of course, one earns miles only in full eco and premiium classes, or
Unless one can't redeem for First, or
Unless they only make one seat available for AA miles, or
Unless they apply a $7,599 Inhalation/Exhalation/Eyelid Motion Surcharge on all redemptions, like British Airways, or
Unless one can't earn miles on certain routes, like Etihad.

I've decided, in this instance, NOT to hold my breath for The World's Best Airline.
