Also consider Greenville-Spartanburg (about 60-70 miles SW on I-85). DL and US probably still have the most flights, but I think it is also served by UA, AA, CO, and NW. Thus, there is a higher level of competition than at CLT where US dominates. However, many of the carriers have substituted regional jets for full jets. And there are still a number of prop plane flights, so be aware if the equip. matters.
