Well, the title is pretty much my question, but specifically, can you pay for BUY ON BOARD meals (starting the 12th or whenever that starts) with CO Currency coupons?
What else will they pay for? Headsets?
I know you can buy drinks with them, but I typically ride up front. I'm planning to give them to a friend who will be flying on the 12th, but he doesn't drink, so if booze is all they're good for, there's no point.

Thanks!
