Egg Mayo - CO's policy of charging for headphones in Economy is, apparently, due to the sheer number that go missing from the tourist cabin. Apparently, they charge a small amount but the passenger is welcome to keep the headphones to use on future flights.
They now charge $4 for in-flight alcoholic drinks in the Tourist cabin, but that money is being used to improve catering.
Penny pinching it may be, but the proof of the pudding is that CO's finances are the strongest of any US or European carrier at the present time!
