My daughter is a student in Hartford that had a round trip from Hartford to Milwaukee. Her return leg was from Milwuakee to Chicago (Ord) to Hartford. She got the opportunity to visit her sister in Chicago for the day before her return to Hartford. She and I tried to convince United to allow her to simply board in Chicago rather than going to Milwaukee to fly back to Chicago to catch her connection to Hartford. United said no. How does this make any sense? She can go online and print her boarding passes from Milwaukee to Chicago and from Chicago to Hartford. United said that if she didn't board in Milwaukee, then it would cancel her trip and she would not be allowed to board in Chicago. Why can't she just skip the redundant trip from Chicago to Milwaukee and back to Chicago? United simply does not care about its customers. Can airlines do this?
