The flight was delayed over an hour late, which in turn made me miss my connecting flight. The agent at the desk in Denver was unwilling to help me rebook a flight, he sent me out side of security to the ticket counter where I was informed that the next available flight would not be until 2 days later and they would not help me with finding a flight on another airline. I even offered to fly to a city close to my final destination and get a rental car to drive the rest of the way and they were unwilling to do that. I ended up having to purchase a flight with another airline and apply for a partial refund for the missed flight that was the airlines fault but they didn't want to help.

Customer service at check in desk needs to improve.
