I used us airways because It was affiliated with hero miles. Well when I arrived at Charlotte NC to switch planes i was supposed to wait an hour and a half for the next plane to leave. Well that didn't happen when i arrived I had to run from one end of the airport to the other end and didn't have enough time to get food to eat on the plane. On my return trip back from Las Vegas I had to switch planes again in charlotte nc. Well at first my plane from charlotte nc to florence SC was delayed. Then at the last minute they canceled it. So I was not able to get a hold of anyone on time to come drive an hour and a half to get me. So the airlines offered a hotel but i had to pay up front and then get reimbursed 75% when the airlines were at fault. Well even if I wanted to stay at a hotel there wasn't anything available because of some race going on. And it wasn't just me going through this there were about 60 other passengers that slept at the airport. Not to mention that i havent eaten for about 12 hours (24 hours by the time I got home). The airlines didn't offer to buy any food or anything to the passengers. They only offered flights for the next day to the destinations the passengers already paid for. This is my 1st time ever using an airplane for this trip so my experience was terrible for my first time. Is the a way I can give them a negative star?
