Both Orbitz and United gave great text message updates about the flight status. Reduced the usual travel stress greatly. Thank you! Understandable maintenance issue caused flight delay and United did a great job making up the time in the air. The only discomfort was the seats. They were very narrow, noticeable decrease in legroom, thin cushioning, and no power for my electronic device. Overall good experience, but comfort could be better.

Boarding computer assigned 2 people to same seat. Clearly mine was wrong. Staff resolved.

Unable to select a “free seat” as none showed available. Then was threatened that the flight was over booked. Felt that I had to purchase a seat in order to fly home.
