Ontario Airport (ONT) Terminal Guide 2026
Ontario International Airport (ONT) is the Inland Empire's primary commercial airport and a major cargo hub for Amazon Air and UPS. With Terminals 2 and 4 (no 1 or 3 — explained below), manageable crowds, and a location that saves 45–60 minutes of driving versus LAX for Inland Empire destinations, ONT is one of Southern California's most practical airports.
No Practical Rail Transit from ONT
While Metrolink's San Bernardino Line has a station about 2 miles from ONT, it serves infrequent commuter trains — not airport shuttle service. For Ontario Mills, Rancho Cucamonga, Chino Hills, Pomona, or any logistics park, private car service is your practical option.
ONT Terminal Layout: Terminals 2 and 4
Why No Terminals 1 and 3?
ONT was managed by Los Angeles World Airports (LAWA) for decades. The terminal numbering reflected a larger expansion plan that was never completed. Since ONT became independently managed in 2016, it has kept Terminals 2 and 4 — skipping 1 and 3 entirely.
| Terminal | Airlines | Gates | Notes |
|---|---|---|---|
| Terminal 2 | American Airlines, Alaska Airlines, Delta, United, JetBlue, Frontier, Volaris | Gates 201–210 | Admirals Club, Delta Sky Club |
| Terminal 4 | Southwest Airlines | Gates 401–412 | Southwest is ONT's highest-volume carrier |
The two terminals are connected by a covered walkway landside (pre-security). After security, Terminals 2 and 4 are separate — check your boarding pass to confirm your terminal before heading through TSA.
Southwest Airlines is ONT's dominant carrier by seat count, operating from Terminal 4. Southwest connects the Inland Empire to Las Vegas, Denver, Phoenix, Chicago Midway, Baltimore, Oakland, and numerous leisure markets — popular with Inland Empire families and logistics executives.
ONT as a Major Cargo Hub: Amazon Air and UPS
The Inland Empire is the largest logistics market in the western United States. Within a 30-mile radius of ONT, there are more Amazon fulfillment centers, UPS hubs, and third-party logistics warehouses than in almost any other region. ONT has been a key part of this infrastructure:
- Amazon Air uses ONT as one of its primary Southern California cargo hubs, with multiple daily freighter operations
- UPS maintains a significant cargo facility at ONT connecting to the UPS Worldport in Louisville
- The Inland Empire logistics market covers approximately 2 billion square feet of warehouse space — larger than the next five US markets combined
- Cargo operations run primarily 10pm–6am, separated from passenger terminal operations
For executives visiting logistics and supply chain operations in the Inland Empire, ONT is the obvious airport. Detailed Drivers provides corporate car service for logistics executives arriving at ONT.
