I have been trying really hard to fly on United, but I have found that seats available on routes I fly are just hard to come by. When traveling for work, never really the price of the ticket, but when I get there and when do I depart.
Granted, I book last minute at times, because of the direction of the company and immediate need to assist a location.
I cannot imagine how more full the ORD-ATL flights could be once they discontinue the DEN and SFO flights in October. I have been wondering the same question, how much the reduced flight will impact those that need to fly but just cannot find flights that work for them with the decline.
