not a problem per se, but it makes the result set "unreliable" at least for me for this search. i'm double-checking it on the AC and UA sites, but that takes way more time than your wonderful tool...
Only had to refresh AC.com a couple times to replicate the same thing.
People grab, hold, and release space all the time. Airline RM systems adjust things all the time. Airline inventory systems fail to return results all the time.
I don't think there's actually an issue with cowtool here.
