Terminal 1 operating hours
As of the latest information available, Terminal 1 at San Diego International Airport (SAN) operates in alignment with the airport's overall schedule, ensuring seamless service for travelers. Terminal 1 operating hours generally follow the flight schedules of the airlines it serves, which primarily include carriers like Southwest Airlines. The terminal typically opens 1.5 to 2 hours before the first departing flight of the day and remains accessible until the last flight has departed and all passengers have cleared the facility. This means that if the earliest flight departs at 5:00 AM, Terminal 1 may open as early as 3:00 AM or 3:30 AM.
It’s important to note that Terminal 1 operating hours are subject to change based on seasonal flight schedules and airline operations. During peak travel seasons, such as holidays or summer months, the terminal may open earlier or close later to accommodate increased flight activity. Conversely, during slower periods, the terminal’s operational hours may be slightly reduced. Travelers are strongly advised to check their flight status and arrival times directly with their airline or through the San Diego International Airport website for the most accurate and up-to-date information.
For arriving passengers, Terminal 1 operating hours ensure that baggage claim and ground transportation services are available until the last flight has landed. This means that even if a flight arrives late at night, the terminal will remain open to facilitate passenger pickup, baggage retrieval, and access to amenities like restrooms and rental car shuttles. However, specific services within the terminal, such as shops and restaurants, may have their own operating hours that do not align with the terminal’s overall schedule.
To avoid any inconvenience, passengers should plan to arrive at Terminal 1 well in advance of their flight, especially during early morning or late-night departures. Security checkpoints within Terminal 1 also have their own operating hours, typically opening 1.5 to 2 hours before the first departure and closing shortly after the last flight has boarded. It’s recommended to verify TSA operating hours and wait times through the airport’s website or mobile app for a smoother travel experience.
In summary, Terminal 1 operating hours at San Diego International Airport are designed to accommodate the flight schedules of its airlines, primarily opening 1.5 to 2 hours before the first departure and closing after the last flight has completed operations. While the terminal remains accessible for arriving passengers until all flights have landed, travelers should confirm their flight times and terminal services in advance to ensure a hassle-free journey. Always check directly with your airline or the airport for the most current information regarding Terminal 1’s operating hours.

Terminal 1 closures or delays
As of the latest information available, San Diego International Airport (SAN) has not announced any permanent closures of Terminal 1. However, travelers should be aware that temporary closures or delays can occur due to various factors such as construction, maintenance, or unforeseen events like severe weather or security incidents. It is always advisable to check the airport’s official website or contact their customer service for real-time updates before heading to the airport.
One common reason for delays or temporary closures in Terminal 1 is ongoing construction or renovation projects.

Passengers are typically redirected to alternative locations within the terminal or to Terminal 2 if necessary. Signs and airport staff are usually available to guide travelers during such disruptions.
Another factor that can cause delays or closures is airline-specific issues.

In such cases, the airport prioritizes safety and follows protocols that may cause temporary inconvenience to passengers.
To minimize the impact of closures or delays, passengers should plan ahead by arriving at the airport early, especially during peak travel times. Utilizing the airport’s mobile app or website for real-time updates can also help travelers stay informed. Additionally, considering alternative routes or terminals, such as Terminal 2, may be beneficial if Terminal 1 is experiencing significant disruptions.
