Experiences at the United Airlines Detroit Off

Hi everyone! Has anyone visited the United Airlines Detroit Office in Michigan recently? Im planning a trip and would love to hear about your experiences. Ive heard the office helps with flight bookings, schedule changes, and baggage issues, but Im curious how smooth the process really is. Are the wait times usually long, or is it manageable if you visit at certain times? Im also interested in how helpful the staff are, especially for first-time visitors. Any tips, advice, or personal stories would be really useful. Sharing your experiences could help others who are planning to visit as well.
