5 stars. Spent Feb 8-10 in Charlotte after being delayed due to Winter Storm Nemo. Although the USO is inside the security area (Food Court mezzanine), the U.S. Airways staff gave me gate passes to head up the USO. I spent two days here, and was able to relax and get a lot of work done. I also had a chance to meet some great Servicemembers and Veterans. Thanks for making my time in CLT pass quickly. I hope to return again, soon.
