Living in Charlotte, most the flights you will take will be US airways unless your dont care abotu havign stops. As much as I complain about flying, US airways does a good job.
For the most part, my flights are on time. With a few exceptions, my flight attendants are always nice. The few times that I have been bumped up to first class, my attendants were even nicer!
They make you pay for a checked bag, but the over head is usually large enough to fit my large carry on roller. (A lot of other airlines use smaller planes that dont.) On domestic flights they offer a drink and choice of small snacks. A lot of airlines have stopped doing this.
On international flights, you can check a bag and they offer a meal which is okay.
