San Francisco Temporarily Closes International Concourse A Gates

Although San Francisco International Airport (SFO) remains open and operational during the Bay Area’s “shelter in place” lockdown, the airport is closing one of two concourses at the International Terminal after a major drop in travel due to the coronavirus. SFO officials say international flights have dropped almost 52 percent in the last few weeks.

The airport currently remains opens “for essential traffic,” despite the state of California entering lockdown due to the ongoing coronavirus pandemic.

All flights using the International Terminal will use a single concourse (Concourse G) beginning Wednesday, April 1. Boarding Area A (Gates A1 – A15) is now closed and all flights in the International Terminal will depart from Boarding Area G (Gates G1 – G14).

The closure is in place until at least the end of May.

Concourse G was used primarily for United and Star Alliance flights, but it is still connected to United’s Terminal 3 landside and via a post-security walkway.

With this concourse closure, SFO will also close a security checkpoint and consolidate Customs and Border Protection to one point of entry for international travel. Some food and beverage outlets will also be closed or have reduced hours.

Even though boarding area A is closed, the SFO medical clinic, the Grand Hyatt and international Parking Garage A are open for essential business. Despite a significant drop in ridership, BART trains and SamTrans are still operating transit services from the airport.

In light of the new coronavirus, SFO has already delayed the opening of the next phase of its new Harvey Milk Terminal 1. The first phase of the revamped terminal was unveiled last summer. SFO is one of many U.S. airports to close gates and reduce operations in the past few weeks. Other airports include Atlanta (ATL), Dallas (DFW), Denver (DEN), Las Vegas (LAS), Los Angeles (LAX) and Phoenix (PHX).


  • Most people hate long flights or overnight layovers, but Albert loves them. The airport and flying parts of traveling are the biggest highlights of any trip for him – as this avgeek always gets a thrill from sampling different airline cabin products and checking out regional developments happening at local U.S. airports. He’s flown on almost every major carrier in the U.S. and Asia Pacific, and he hopes to try out the new A350s soon. Albert recently completed his undergraduate studies in Business Accounting at USC in Los Angeles and he is currently recruiting for a corporate analyst position at one of the U.S. legacy carriers. During his college years, he interned at LAX for Los Angeles World Airports working behind-the-scenes (and on the ramp) in public relations and accounting. Outside of writing for AirlineGeeks, he enjoys trekking the Hollywood hills, visiting new hotspots throughout SoCal, and doing the occasional weekender on Spirit Airlines.
