Makes since. My two home airports (virtually the same distance from each other) have RJ aircraft and I am usually consistently upgraded with the 500 mile complimentary into DFW. When leaving JAX heading home on a Friday, its hit or miss. Didn't want to end up burning or buying stickers if I didn't necessary need to but it looks like that's want AA wants you to, understandably so...
