No food for a 5-6 hour flight unless you pay extra, and then it's minimal. Also no in-flight "entertainment" (ie videos or music).This is the new norm but it sucks. Not just Alaska Airlines; I like Alaska Airlines. The whole airline industry is trying to extract as much/deliver as little as possible. Why was it possible 20 years ago to check a bag and have a meal on a long flight? I will obviously keep flying since I have no choice if I need to be somewhere, but how the travel industry (not just the travel industry--also, health care and more) operates these days makes me question humanity. Does everything boil down to money, and the ones in charge getting every penny they can possibly get?
