Flight from Boston to CLT was delayed due to mechanical issues, prompting us to miss our connecting flight to Las Vegas. We went to the customer service desk which was adjacent to C9 where we spoke with Michelle. She informed us US Air had us rebooked two hours later but flight was completely sold out, we would have to sit separately away from each other. The agents said check back in a few, which we did and they were able to accommodate our seating. While it may not seem like a major deal, all three women at that desk were absolutely awesome and even though the line seemed insurmountable, they got it done. Thanks to all the workers at that station for making our travel easier and for being consummate professionals at the same time.
