Hello! My recent visit to the United Airlines SAN Terminal was very smooth. As soon as we got there, the signage was good and it was easy to navigate. The check-in counter staff were friendly and efficient, making the beginning of our family vacation trouble-free. Security lines were a breeze, and there were nice TSA agents in between. We enjoyed the airy design of the terminal—it was never cramped at all. There were ample sitting areas, and the restrooms were clean and well-stocked. Overall, the United Terminal at San Diego International Airport was a comfortable and dependable experience.
