About Ontario International
Ontario International is the third-largest airport serving the LA metro area and sits 35 miles east of downtown LA in San Bernardino County. It's significantly less crowded than LAX or Burbank, making it your best bet for avoiding terminal chaos—security lines rarely exceed 15 minutes even during peak travel. Southwest Airlines operates a major hub here with 40+ daily departures, making it their strongest West Coast presence outside California's major cities. The airport primarily serves the Inland Empire (Ontario, Riverside, San Bernardino counties) and has become increasingly important for leisure travelers willing to drive 45 minutes from LA proper to skip the airport madness. Most international routes here are seasonal or limited compared to LAX, but domestic prices are often $50–150 cheaper on identical flights due to lower passenger demand.
Terminals & Airlines
Ontario has a single terminal building split into two piers (North and South). Southwest dominates the North Pier with 25+ gates. American, United, Delta, and Alaska operate from the South Pier. Alaska Airlines has a dedicated check-in area on the South side. International flights (limited to Canada, Mexico, and occasional charter service) depart from the South Pier. The terminal is compact and walkable—no trains needed—making connections simple if they happen. TSA PreCheck and CLEAR both operate here.
Getting to the Airport
Metrolink train from Downtown LA (Union Station) runs to Ontario Station (30 min ride, $8.50 one-way, but requires 15 min walk to terminal or $5 shuttle). Not practical for early flights. Ride-share (Uber/Lyft) from downtown LA: $35–55, 50–65 minutes depending on traffic; from San Bernardino: $12–18, 15 minutes. Rental car from downtown: $40–70/day with parking. Best option for most travelers: drive yourself and use the hourly lots ($3/hour, max $18/day) or valet ($15). GTFO if flying before 6 AM—public transit won't work, and you'll pay surge pricing for rideshare.
Parking
Hourly lot: $3/hour, $18 daily max. Always better than valet for anything under 4 hours. Long-term economy parking: $12/day if booked online, $15 walk-up. Valet: $15 standard, $25 premium. Off-airport lots charge $8–10/day but require shuttle service—not worth the hassle given ONT's cheap on-airport rates. Park in the South Lot if flying Southwest (North Pier); it's a 5-minute walk versus 15 minutes from the economy lot.
Airlines at ONT
Pro Tips for Flying from Ontario
Southwest bags fly free at ONT just like everywhere else, but the airline's lighter load here means faster bag claim—you'll see your luggage 10 minutes sooner than at LAX.
If you're in San Bernardino, Riverside, or the Inland Empire, ONT is 30–40% cheaper than LAX on most routes because airlines don't charge origin premiums. Book ONT instead of LAX even if you live in Orange County—the $100+ savings justify the 30-minute drive.
The food court has decent options (Burger King, Subway, local chains) but prices are only moderately inflated. Skip the terminal restaurants entirely and eat before security.
Arrive 90 minutes before domestic flights, not 2 hours—this airport moves fast. For international flights, go 2 hours early, but you'll still clear security faster than LAX.
