All US nonstop flights CLT-PHX on Feb 18 are sold out, except
#705 (5.49pm dep)
#309 (7:50p dep)
both of which are showing F1 A1 P1 (etc), which basically means 1 FC seat left for sale at either full-fare F, discount F ("A" fare) or Y/B instant Preferred upgrade ("P" availability).
As
USFlyer26 mentions upthread, there are various tools out there to show this kind of info.
