Hello, My mom had an incredible experience at the United Airlines DEN Terminal. The staff was courteous and professional when she arrived to inquire about altering her ticket. They thoroughly explained the options and any associated fees, and they also made sure she understood the process. The terminal's order and user-friendly design made her visit simple. She appreciated how promptly and efficiently her inquiries were addressed, as well as their professionalism. Overall, she thought it was a smooth and delightful experience.
