Johnny says that if you fly a lot, enough to gain frequent flyer miles, it's best to stick with a single airline that you can build miles with. But if you fly infrequently, then shop around for the best deal when you do. He also says that if you get asked if you want to upgrade to "premium economy," it's a big scam. Johnny also says that airlines are now charging for gate check-in of luggage at $25 a bag or more. They'll also charge you to print your boarding pass.
