Are flight was delayed in Sarasota Florida making it impossible to catch are connecting flight in Chicago to Moline. I went to gate B1 on 09-11-21 to ask what I can do since It's impossible to make my connecting fight. The American Airline gate ticket lady was so rude and unprofessional that the people behind me said something to her about her behavior and put me in a uncomfortable position. So now I'm stuck at the airport an additional 6 hours, out $120 that I payed for preferred seating, and angry by the way I was treated. I was a former American Airline employee and we were never allowed to treat people this way. I guess now days people just don't care..
