SJC San Jose Airport Terminal Map (2025)

Navigating SJC has gotten complicated with all the conflicting info flying around. I fly through San Jose International Airport maybe four or five times a year for work, and every single time someone asks me for advice about it, I end up explaining the same things. So I’m putting it all in one place. This is based on my actual experience walking these terminals, not a press release rewrite.

The Two Terminals: A and B

SJC has two terminals, and knowing which one you need saves you from that panicked moment where you realize you’re in the wrong building. I’ve done that exactly once. Won’t happen again.

Terminal A is home to United, Alaska, and Delta. The layout is a central concourse that branches out to the gates. Security is generally predictable here, though I’ve seen it back up during Monday morning business travel waves. The terminal has lounges, fast food spots, and some shopping. Nothing remarkable, but it gets the job done.

Terminal B is where Southwest and American Airlines operate. This one is the newer terminal, and you can tell. The architecture is more modern, walkways are wider, and the seating areas don’t feel as cramped. Dining options are a step up from Terminal A, and there are plenty of charging stations. Probably should have led with this: if you’re flying Southwest, you’re in Terminal B, and that’s honestly the nicer of the two buildings to spend time in.

Gates and Finding Your Way

Terminal A runs Gates 1 through 16. Terminal B covers Gates 17 through 28. Every gate has restrooms nearby and vending machines, which sounds basic but I’ve been in airports where that wasn’t the case. Flight information monitors are placed throughout, and they’re actually readable from a distance, which I appreciate more than I probably should.

The whole airport is honestly pretty easy to navigate. I’ve watched first-time visitors figure it out without much trouble. SJC doesn’t have that overwhelming maze quality that SFO or LAX hits you with.

Parking: What I’ve Learned the Hard Way

A few parking options depending on your situation:

Hourly Lot 2 is right next to the terminal. Good for pickups and drop-offs, but expensive if you leave your car for more than a couple hours. I made that mistake once and the bill was eye-opening.

Economy Lot 1 is where you want to park for longer trips. The rates are much more reasonable, and a shuttle runs between the lot and the terminals on a regular schedule. The shuttle wait has never been more than about ten minutes in my experience.

Green Island offers valet parking if you want the convenience of dropping your car and walking straight in. It costs more, obviously, but on mornings when I’m running late for a flight, the temptation is real.

Getting To and From the Airport

VTA public transit serves SJC and it’s a budget-friendly way to reach downtown San Jose. I’ve used it a few times and it works fine if you’re not in a hurry. Uber and Lyft pick up from designated zones outside the terminals. Taxis are available too, and car rental counters are on-site for people who want their own wheels.

One thing worth mentioning: the ride-share pickup spots moved a while back, so if you haven’t flown through SJC recently, follow the current signage rather than relying on memory. I walked to the old spot once and stood there looking confused for five minutes before a helpful stranger pointed me in the right direction.

Security and Check-In

TSA runs the security operation. I’d say arrive at least two hours before a domestic flight. The lines can be short, but they can also surprise you, especially during holiday travel or those Monday morning rushes I mentioned. Both traditional check-in counters and self-service kiosks are available, and the kiosks work well if you already have your boarding pass on your phone.

Food, Shopping, and Killing Time

The dining ranges from quick grab-and-go to actual sit-down meals. There are chain restaurants you’ll recognize and a few local options that are worth trying. Shopping covers travel necessities and some nicer stuff. Duty-free is available for international travelers. None of it is going to be the highlight of your trip, but you won’t go hungry or bored either.

Wi-Fi and Lounges

Free Wi-Fi throughout the airport, and it’s reliable enough for video calls, which is my usual benchmark. Charging stations are in every waiting area. The Club at SJC is the main lounge option, offering workstations, drinks, and snacks. I’ve used it on longer layovers and it’s a nice escape from the gate area noise.

Accessibility

That’s what makes SJC endearing compared to larger Bay Area airports. They’ve put real thought into accessibility. Reserved parking for passengers with disabilities, wheelchair assistance on request, accessible restrooms that are clearly marked, elevators and escalators everywhere, and the TSA Cares program for travelers who need extra help with screening. It all works together in a way that feels intentional rather than afterthought.

What’s Ahead for SJC

Expansion plans are underway. Terminal improvements and better transportation connections are the main focuses. Silicon Valley keeps growing, and the airport is trying to keep up with passenger demand. I’m curious to see how the construction affects the travel experience in the short term, but long term it should mean more gates and better facilities. Fingers crossed they don’t lose that manageable feel in the process.
