San Diego International Airport (SDIA) is in a convenient downtown location largely because the tourism industry, including the downtown convention bureau and hoteliers, pushed hard to keep it there in a city-wide vote. However, these groups have overlooked the eventuality of SDIA reaching capacity. Over the decades, the number of operations has approached capacity, only to drop off due to global events like the 2008 economic crash and the 2021 pandemic. Once again in 2024, operations are nearing capacity.
Initially beginning at about 85 percent of capacity, the airport becomes constrained. Besides irate passengers waiting on the taxiways, there are significant consequences. The airport is surrounded by hills to the east and west and has a parking structure that decreases arrivals runway length. Coastal weather also leads to one of the highest number of missed approaches per operation in the US. Recently, an incident occurred when an aircraft was cleared to cross the runway at the same time another was cleared for takeoff. Fortunately, the aircraft was able to stop by hitting the brakes hard. Such incidents might increase as the airport becomes constrained. The Airport Authority, supported by the FAA, may maximize operations or may decide to limit the number of operations before there are too many issues.
