After a three hour delay and five gate changes, my American Airlines flight is now adding ballast to the plane before we can take off. Yes, ballast. This, after charging me $25 for my single checked bag. Supposedly, they charge for checked bags because luggage makes the plane heavier and correspondingly, use more fuel. Now they are adding ballast. Soon they’ll be charging for air. After your third delay you’ll see a guy with a bike tire pump chasing your plane around the tarmac.
