I flew from Delta Airlines SAN Terminal It was a smooth and pleasant experience. The terminal is clean, modern, and easy to navigate. Even check-in and security were pretty good, with friendly, helpful personnel on duty. The great diversity of food and retail is such a great touch, and there are so many cozy places to sit. Baggage claim came through pretty smoothly, and there were a number of transportation options conveniently located for me to make my trip easier. Overall, Delta delivered a great travel experience.
