US Airways lost my carry on luggage in Charlotte which I checked, as a courtesy to them, after they went on the loud speaker asking for volunteers to check luggage because of such a full flight. I waited 90-minutes and they were not even apologetic. There were quite a number of poor consumer at their baggage counter experiencing the same. And this flight was contracted by American Airlines. I will NEVER AGAIN KNOWINGLY SPEND MY MONEY TO BOOK A FLIGHT ON US AIRWAYS!
