Southwest Florida International Airport (RSW) has shelved plans for a parallel runway until at least the early 2040s, despite its status as the United States' second busiest single-runway airport. Initially scheduled for 2020, the decision to delay the construction takes into account various factors, including financial feasibility and current traffic demands.
Passenger volume at San Diego International Airport (SAN), which remains the busiest single-runway airport in the U.S., reached a record 25.24 million in 2024. “San Diego International Airport (SAN) marks 2024 as its busiest year ever with 25.24 million passengers recorded traveling through the airport’s terminals. This record-breaking year surpasses the previous busiest record of 25.18 million passengers served in 2019,” said Nicole Hall, Senior Communications Specialist for San Diego International Airport.
RSW saw more than 11 million passengers in 2024, marking a nearly 10% increase from the previous year, as reported by the Bureau of Transportation Statistics. The growth correlates with increased travel flexibility due to the rise of remote work arrangements post-COVID-19.
