I have (or had) a trip in May booked on United and was waiting to see what would happen. Today I noticed I had a schedule change that was impossible. I was now scheduled to arrive in one city an hour later than the connecting flight was scheduled to leave. I called United and prepared for a long wait as well as an argument but I got neither. I had zero wait time and once she looked at the connection, she actually laughed. She said "I will put in a request for a full refund which might take eight weeks." So, there might be some hope out there for those of you wanting a refund. Keep checking the flight times and see what United does. By the way, I got no notice of the flight change; I only found it by logging into my account and checking.
