After a delayed bag, I needed to collect baggage tag, airport, flight number, and delivery address. The complaint notes section helped me prepare the details before following up with United Airlines.

United Airlines had several booking details to check, so I used this page to keep the reservation number, route, and support links in one place before calling. The IATA UA detail also helped me confirm I was looking at the right airline.
Special assistance request was unclear
Wheelchair assistance details were not clear during booking, so I used the form prompts to outline the passenger name, route, and timing. It made the United Airlines support request easier to explain.
Group travel planning felt less scattered
For a small group itinerary, I used this page to organize traveler names, route options, and booking questions before contacting United Airlines. It worked well as a support planning checklist.

A seat upgrade request was difficult to explain without all fare and payment details. I used this page to organize the request before asking United Airlines for options.
