You canceled my original flight morning of flight. The new flight had 3 connections and seat were not comparable. I book early to get the aisle seats for my height. When I tried to talk to a staff member at desk in Denver, she was rude and said nothing she could do. The seat was in boarding group 4, made me check my bag. When I got on the flight, there was clearly over head space available. When I mentioned that there was space available, no response. It was a frustrating trip
