SJC Airport Terminal Guide: Gates, Airlines & Tips 2026

San José Mineta International Airport is a mid-size Bay Area airport with two passenger terminals, 36 gates, and a straightforward layout that most first-time visitors can navigate in minutes. This SJC airport terminal guide covers Terminal A and Terminal B in detail — which airlines fly from each, how security works, how to move between terminals, and how to time your arrival. Before you reach the gate, you also need to park: off-site lots booked through Triply start at $7.79/day, compared to $19/day for Economy Lot 1 and up to $41/day for the Terminal B Garage.

• Two terminals, one airport: Terminal A serves American, Delta, Frontier, United, and Volaris. Terminal B serves Southwest, Alaska, Hawaiian, and ZIPAIR.
• 36 gates total across both terminals, per official airport data from the City of San José Airport Department.
• Southwest holds roughly 58% of SJC's seat share — making Terminal B the busiest side of the airport on most days.
• TSA PreCheck lanes are available in both terminals — enrollment can cut security wait times significantly.
• Off-site parking from $7.79/day (Joy Park Fly, verified October 2026) beats on-airport rates by up to 59%.
• The VTA Route 60 Airport Flyer is free from SJC — board at Terminal A Stop 7 or Terminal B Stop 5.

SJC Airport Terminal Guide: Terminal A and Terminal B Overview

SJC has two side-by-side terminals connected airside and separated landside. Terminal A sits on the north side of Airport Boulevard. Terminal B sits to the south. Each terminal has its own check-in counters, security checkpoint, baggage claim, and ground transportation zone.

The airport is operated by the City of San José Airport Department and sits about 3 miles northwest of downtown San José via SR 87 (Guadalupe Freeway). Access from the north comes via US-101 (Bayshore Freeway) and I-880 (Nimitz Freeway). Before you drive, check real-time traffic on Waze — Airport Boulevard can back up during peak commute hours.

Airlines at Terminal A

Terminal A is home to the legacy and international carriers at SJC. If you are flying on any of these airlines, check in, clear security, and head to the Terminal A gates.

• American Airlines
• Delta Air Lines
• Frontier Airlines
• United Airlines
• Volaris (international — Mexico routes)

Airlines at Terminal B

Terminal B handles SJC's highest-volume carrier and three other airlines. Southwest alone accounts for roughly 58% of seat capacity at SJC, so Terminal B sees heavy traffic on weekends and holidays. Plan extra buffer time if you are flying Southwest during busy travel periods.

• Southwest Airlines
• Alaska Airlines
• Hawaiian Airlines
• ZIPAIR (Tokyo-San Jose route)

How Do You Get Between Terminal A and Terminal B?

Once you pass security, the two terminals connect airside. You can walk between them without re-clearing security. This matters if your connection involves airlines in different terminals. Landside — before security — you must exit one terminal, cross Airport Boulevard, and enter the other. Free airport shuttle buses also link Terminal A, Terminal B, and the Rental Car Center on the landside.

If you have a tight connection that crosses terminals, confirm with your airline whether you need to re-clear security. In most domestic scenarios, the airside walkway keeps you in the sterile zone the whole time.

Parking by Terminal: Which Lot Should You Use?

Each parking lot is mapped to a terminal. According to official airport data from flysanjose.com (verified October 2026):

Note as of 2026: The Hourly Lot 2 north garage exit is closed for construction. Use the south exit. Premium Reserved parking on Lot 2's second floor launched July 23, 2026 — reservation only at $40/day. For a deeper breakdown of every lot address and gate-level layout, see our SJC parking map and lot guide.

SJC Airport Terminal Guide: Security, TSA PreCheck, and CLEAR

Both Terminal A and Terminal B have dedicated TSA security checkpoints. Each checkpoint has standard lanes plus TSA PreCheck-designated lanes. TSA PreCheck enrollment lets approved travelers keep shoes, belts, and laptops in their bags — typically cutting checkpoint time from 15-20 minutes down to under 5. Enrollment costs $78 for five years and is available at SJC and hundreds of other airports.

CLEAR biometric lanes, which use fingerprint and iris scans to verify identity, are also available at SJC. The CLEAR security program works alongside TSA PreCheck — CLEAR gets you to the front of the ID check line, and PreCheck speeds up the physical screening. Combining both is the fastest path through security at SJC.

Review TSA's official screening rules before you pack. Prohibited and restricted items cause most of the delays at checkpoint — knowing what you can and cannot bring saves everyone time.

What Time Does SJC Security Open?

SJC security checkpoints open early enough to handle the first wave of departures, which typically begin around 5:30–6:00 a.m. Exact opening times can shift, so confirm with your airline or check flysanjose.com before an early morning flight. For a full breakdown of timing strategy for pre-dawn departures, our SJC parking for early morning flights guide covers shuttle schedules and lot-by-lot timing in detail.

How Early Should You Arrive at SJC?

The standard advice at SJC — and consistent with what the TSA recommends — is to arrive at least 2 hours before domestic departure and 3 hours before international flights. That buffer needs to include parking and the shuttle ride, not just security. Here is a realistic timeline for off-site parkers:

1. Arrive at your parking lot and check in — allow 5 minutes.
2. Wait for the shuttle and ride to the terminal — allow 15-20 minutes total (Joy Park Fly runs every 5-15 minutes; Spring Park and Holiday Inn San Jose Airport are on-demand, 24/7).
3. Check bags at the counter — allow 10-15 minutes on busy days.
4. Clear security — allow 15-30 minutes without PreCheck, 5-10 with it.
5. Walk to your gate — allow 5-10 minutes depending on gate location.

Add that up and a 2-hour arrival window is tight for off-site parkers on a busy morning. Three hours gives you real breathing room. Economy Lot 1 on-airport parkers should budget the same, since the shuttle runs every 7-10 minutes and adds transit time before you even reach the check-in counter.

SJC Airport Lounges, Wi-Fi, and Airport Services

SJC offers a notable set of passenger amenities for a regional airport. The flagship lounge is The Club SJC, located in Terminal A near gates A15 and A8, per official airport information. The Club SJC is an independent pay-per-use lounge open to any traveler — no airline status or specific credit card required. Amenities include complimentary food, snacks, and beverages, plus quiet seating and Wi-Fi. Access fees and hours can change, so check FlightQueue's SJC lounge directory for current pricing before your trip.

Wi-Fi at SJC

Free Wi-Fi is available throughout both terminals. Connect to the sjcfreewifi network — no password or paid login required. Signal is generally reliable in gate areas and baggage claim.

Ground Transportation: Getting To and From Each Terminal

SJC's ground transportation is well organized, with clear zones for rideshare, taxis, and public transit at each terminal. All major options depart from the outer curb of each terminal building.

Rideshare and Taxis

Uber, Lyft, and taxis pick up outside both terminals. For arrivals, collect your bags first, then request your ride. Pickup spots are at the designated rideshare zones on the arrivals level. Taxis operate from the same curbside area — details are on flysanjose.com/taxis.

VTA Route 60 Airport Flyer

The VTA Route 60 Airport Flyer is free from SJC. Board at Terminal A Stop 7 or Terminal B Stop 5. The bus connects the airport to the Metro/Airport light rail station, where you can transfer to the VTA Blue or Green Line (fare required). From there, you can reach Downtown San José, Santa Clara, Milpitas, and other neighborhoods. Check schedules at vta.org.

Rail Connections

SJC does not have a direct light rail stop at the terminals, but connections are close:

• VTA Light Rail — Metro/Airport Station, reachable via the free Route 60 bus.
• BART — Milpitas Station is the nearest BART stop. Details at bart.gov.
• Caltrain and ACE — Santa Clara Transit Center.
• Amtrak and Greyhound — San José Diridon Station, about 3 miles from the airport.

Off-Site Parking Shuttle Pickup After Landing

All three Triply-verified off-site lots run free 24/7 on-demand shuttles. After you collect your bags, call your lot and they dispatch the shuttle. Here is the breakdown by lot (verified October 2026, based on current Triply listings):

Based on current Triply rates, booking an off-site lot instead of Economy Lot 1 ($19/day) saves you up to 59% per day. On a 7-night trip, that gap adds up to more than $78.
