MSN Money analyzed the situation and noted, "What happened? Well, in this airline's case, it was more about what didn't happen. First, other airlines didn't follow US Airways' lead. Sure, they were fine with fees for checking bags and other things, but they drew the line when it came to charging for drinks. Second, passengers didn't accept the fee. It became about more than a soda."
If you normally fly first class and don't ever pay for beverages, this won't affect you. But if you are watching your money a bit more and may now fly coach, at least you'll have a few extra dollars to spend on other things.
