US airways is just terrible. I'm so thankful for Alaska airlines. Us airways would rather let an empty seat stay empty than put me on standbye. The gate agent (who was polite) stated it would be $75 to be moved to an earlier flight and that standbye didn't exist anymore. Really??! Not only is it shitty customer service, it blatantly makes NO sense to let a seat go empty. What's wrong with upper management of airlines? If you're not going to have comfortable planes or good customer service, at least have policies that make logical sense!

NEGATIVE
