San Jose Mineta SJC: the complete layover guide

SJC is one of the easiest major airports in America to navigate: two terminals in a straight line, one airside walkway between them, and nothing more than a 15 minute walk from anything else.

Terminal A and Terminal B sit next to each other along Airport Boulevard. Southwest, the airport's biggest carrier, flies from Terminal B, and most other airlines use Terminal A, though assignments do shift, so check your booking on the day. Once you are through security, the two concourses connect through a pedestrian walkway near Gate 16 in Terminal A and Gate 17 in Terminal B. The walk takes 2 to 3 minutes. No bus, no train, no second screening.

That walkway is the quiet superpower of this airport. It means a connection between any two gates at SJC is a stroll, not a project, and it means you can pick whichever security checkpoint has the shorter queue and walk to your gate from there if you are traveling with carry on only. It also means everything airside is shared in practice: Terminal B passengers can use the Terminal A lounges, and Terminal A passengers can eat in Terminal B.

Landside, the layout is just as simple. Both terminals open onto the same access road, the rental car center sits across from Terminal B, and the free VTA Route 60 bus stops outside both buildings. There is no satellite concourse, no inter terminal train and no 25 minute gate sprint. After a connection through SFO or LAX, this place feels like a regional airport that happens to serve 12 million passengers a year, in the best way.

Timing honesty: for a domestic connection on one ticket, 45 minutes is comfortable here if your inbound is on time. Security queues are the only real variable, and they are usually modest outside the early morning Southwest bank. On separate tickets with checked bags, give yourself 2 hours like anywhere else.

You can stay overnight at SJC if you are a ticketed passenger with a valid boarding pass for a connecting flight. That is the airport's official policy. Whether you will actually sleep is another matter.

There is no designated rest zone, no sleep pods and no in terminal hotel. Most gate seating has fixed armrests, and the airport itself warns that security announcements continue intermittently through the night. The security checkpoints also close overnight and reopen before the first morning departures, with exact reopening times to be confirmed, so if you exit airside late in the evening you will be waiting landside until they open again. Plan for an upright night with a hoodie and earplugs, not a lie down.

The terminals are at least safe, clean and quiet by big airport standards. San Jose runs a small overnight operation, so you will share the building with cleaning crews and a handful of fellow strandees rather than crowds.

If your layover runs longer than about 8 hours overnight, a bed nearby beats the floor on value. The DoubleTree by Hilton San Jose sits about half a mile from the terminals with a free shuttle, and the Sonesta Select San Jose Airport is roughly the same distance with a 24 hour shuttle of its own. Several more hotels with free airport shuttles sit within a mile. With a 10 minute shuttle ride each way, even a 6 hour gap can buy you 4 real hours of sleep. The full sleep map, including which corners stay quietest and where the unarmed benches hide, is in our sleeping at SJC guide.
