Travelers in Fontana, California, enjoy a position that many Southern Californians envy: they're located between two airports that each serve a distinct type of passenger. Ontario International Airport (ONT) is a full-service commercial gateway handling millions of passengers a year with nearly a dozen airlines. San Bernardino International Airport (SBD), just to the east, has emerged as a tiny, ultra-efficient terminal where budget airline Breeze Airways runs low-cost nonstops. Whether you're chasing the lowest fare or need a reliable business-class seat to a major hub, knowing your airline options at both airports helps you craft a trip that saves time and money.

Key Takeaways

  • Fontana residents can reach Ontario International (ONT) in about 15-20 minutes and San Bernardino International (SBD) in roughly 15 minutes, giving them two very different airports.
  • ONT hosts Alaska, American, Delta, Frontier, Hawaiian, Southwest, Spirit, and United, with nonstop flights to over 20 U.S. and Mexico cities.
  • SBD's only scheduled carrier is Breeze Airways, offering point-to-point flights to Phoenix, San Francisco, Provo, and seasonal routes, with free parking and minimal lines.
  • Southwest is the only airline with two free checked bags and no change fees; Frontier and Spirit have the lowest base fares but charge for overhead bin space.
  • Both airports are significantly less stressful than Los Angeles International, with short security lines, cheaper parking, and terminals that rarely feel crowded.

Understanding the Airports Near Fontana: Ontario and San Bernardino

The Inland Empire's aviation landscape is defined by these two airports, and they cater to almost opposite travel styles. Ontario International is the workhorse, handling the majority of scheduled passenger flights for the region. San Bernardino International is the plucky alternative for those who prize speed and a low price above all else.

Ontario International Airport (ONT)

Ontario International Airport operates two terminals (2 and 4) and two runways. Its airline roster includes major network carriers, low-cost operators, and even a Hawaiian island specialist. You can fly to hubs like Dallas/Fort Worth, Denver, Atlanta, and San Francisco, or to leisure destinations such as Las Vegas, Phoenix, and Cancún. ONT's design—never as congested as LAX—means you're likely to move through security in under 10 minutes on a typical day.

San Bernardino International Airport (SBD)

San Bernardino International Airport took over part of the former Norton Air Force Base and opened its modern passenger terminal in 2022. It now serves as the Southern California base for Breeze Airways. With just a few flights a day, the terminal is refreshingly quiet. The parking lot sits directly across from the entrance and is free when space is available. If your destination is on Breeze’s short route map, SBD can deliver a curb-to-gate time of under 15 minutes.

Which Airport Should You Choose?

Go to ONT if you need connecting flights, want multiple daily frequencies, or value airline lounges and full-service amenities. Pick SBD if you're taking a nonstop Breeze flight, traveling with only a personal item, and appreciate an airport where you can arrive 45 minutes before departure without stress. For many Fontana families, the choice comes down to the specific destination: if Breeze flies there, SBD wins; otherwise, ONT is the logical second option.

Full-Service Airlines at Ontario International: Networks and Perks

ONT’s lineup of legacy and full-service carriers covers the U.S. map and parts of Mexico with daily flights to major hubs. Understanding each airline's focus can help you pick the right loyalty program or product for your trip.

American Airlines

American connects Fontana to Dallas/Fort Worth, Phoenix, and Chicago O’Hare. From DFW and ORD, you can reach hundreds of domestic and international destinations. Main Cabin Extra seats offer added legroom, and AAdvantage members can earn miles toward status. Travelers with an eligible American Airlines credit card can check a bag for free.

Delta Air Lines

Delta flies nonstop to its hubs in Salt Lake City, Atlanta, and Minneapolis–St. Paul. The airline is known for consistent onboard service, with seatback entertainment on many mainline aircraft. Delta’s Comfort+ provides extra legroom, dedicated bin space, and complimentary drinks. SkyMiles members get perks like same-day confirmed changes and free Wi-Fi on certain routes.

United Airlines

From ONT, United runs regular service to Denver, Houston Intercontinental, and San Francisco. These hubs open up transcontinental and transpacific connections. United's Economy Plus offers up to 6 extra inches of legroom, and MileagePlus members can use miles to upgrade. If you fly United frequently, consider a United Explorer Card to get a free checked bag.

Alaska Airlines

Alaska focuses heavily on West Coast routes: Seattle, Portland, San Francisco, and San Jose. The airline’s Mileage Plan is one of the most generous loyalty programs, and its premium cabin on these short hauls features local food and craft beer. Alaska also offers a companion fare with its credit card, making it a favorite for couples heading to the Pacific Northwest.

Hawaiian Airlines

When you need a direct escape to the islands, Hawaiian’s nonstop to Honolulu (seasonal and scheduled) saves you the LAX drive. Hawaiian’s warm service and complimentary meals on the mainland-to-Hawaii route contrast with the budget experience. HawaiianMiles can also be used on partner airlines like JetBlue.

Low-Cost Carriers at ONT: Southwest, Frontier, and Spirit

Ontario’s low-cost trio competes fiercely on flights to Las Vegas, Phoenix, Denver, and the Bay Area. Each has a distinct pricing model, and knowing how to dodge the fees can cut your total trip cost dramatically.

Southwest Airlines

Southwest flies nonstop from ONT to Las Vegas, Phoenix, Denver, Oakland, Sacramento, San Jose, and seasonally to Chicago Midway and Dallas Love Field. The airline’s signature policies—two free checked bags, no change fees, and no cancelation penalties—differentiate it from all other low-cost carriers. Seats are not assigned; boarding position is determined by check-in time. If you check in exactly 24 hours before departure, you’ll almost always get a good spot. The Companion Pass, earned by flying 100 qualifying one-way flights or earning 135,000 points in a calendar year, lets a designated companion fly with you for just taxes and fees on any Southwest flight, making it one of the best deals in travel.

Frontier Airlines

Frontier offers ultra-low base fares to Denver, Las Vegas, and Phoenix from ONT. However, you’ll pay extra for a carry-on bag larger than a personal item, and checked bags come with fees that can be higher than the ticket itself. The Discount Den membership (about $60 per year) unlocks lower fares and often kids fly free promotions. If you can pack everything into a backpack that fits under the seat, Frontier often beats all competitors on price. Seat pitch is tight at 28 inches, so consider paying for a stretch seat if you’re over 6 feet tall.

Spirit Airlines

Spirit operates flights to Las Vegas and occasionally Phoenix from ONT. Its fare model mirrors Frontier’s: base tickets are cheap, but you’ll pay for seat selection, carry-on bags that go in the overhead, and any drinks or snacks. The $9 Fare Club provides access to discounted fares and lower baggage fees. Spirit’s Big Front Seat offers the same space as domestic first class for a fraction of the price. If you’re doing a quick weekend in Vegas with only a personal item, Spirit’s prices are hard to beat.

A Complete Nonstop Route Map from Ontario (ONT)

Knowing which cities you can reach without a connection helps you plan a faster trip. Here’s a quick reference of nonstop destinations by airline (subject to seasonal changes):

  • Alaska Airlines: Portland, San Francisco, San Jose, Seattle
  • American Airlines: Chicago O’Hare, Dallas/Fort Worth, Phoenix
  • Delta Air Lines: Atlanta, Minneapolis/St. Paul, Salt Lake City

International nonstops include Cancún, Guadalajara, Los Cabos, and Puerto Vallarta, primarily on Frontier and Volaris.

San Bernardino International Airport and Breeze Airways: A Low-Stress Alternative

San Bernardino International’s passenger terminal might be small, but it’s designed for speed. The parking lot is steps from the entrance, and the single security checkpoint rarely has more than a few people. For travelers willing to fly solely on Breeze, SBD can deliver the fastest door-to-gate experience in Southern California.

Breeze Airways started service from SBD in 2022 and has steadily added routes. The airline focuses on connecting mid-sized cities that have been neglected by larger carriers. Current nonstop destinations from SBD include:

  • Phoenix Sky Harbor (PHX)
  • San Francisco (SFO)
  • Provo, Utah (PVU)
  • Seasonal service to other western cities like Las Vegas and possibly Orange County may appear.

Breeze operates a mix of Embraer E190/E195 jets and Airbus A220-300 aircraft. The A220 is a standout: three-abreast seating with wider seats than a typical 737, large windows, and a quiet cabin. Breeze’s fare bundles let you choose your level of service. The “Nice” fare includes just a personal item; “Nicer” adds a checked bag and extra legroom; “Nicest” functions as a first-class seat with complimentary snacks and drinks. For a solo traveler headed to San Francisco for a weekend with just a backpack, the “Nice” fare is often staggeringly cheap—sometimes under $40 one-way.

Comparing Airline Comfort, Baggage, and Flexibility

Price alone never tells the full story. Fees, seat comfort, and change policies can turn a cheap ticket into an expensive headache. Use this table to see how each airline stacks up on key factors for flights from the Fontana-area airports.

Airline Free Carry-on (overhead) Checked Bag Fee (first bag, typical) Seat Pitch (economy) Change/Cancel Fee
Southwest Yes (plus 2 free checked bags) $0 for first two 32 inches No fee; credit issued
Delta Yes $30 31-32 inches No change fee for main cabin and above
American Yes $30 31-32 inches No change fee for main cabin and above
United Yes $35 31 inches No change fee for economy plus and above
Alaska Yes $30 31-32 inches No change fee for main cabin
Hawaiian Yes $30 31 inches No change fee
Frontier Only personal item included; overhead $35+ each way $40+ (varies by route and purchase time) 28-29 inches $49-99 fee if not added at booking
Spirit Only personal item; overhead $30+ each way $35+ (varies) 28 inches $49-119 fee
Breeze (Nice fare) No; personal item only $30-35 (Nicer fare includes one) 30-32 inches (varies by aircraft) Credit or fee depending on fare

Onboard Wi-Fi and entertainment: Delta, American, and United offer in-flight Wi-Fi for a fee or free on select planes and routes. Southwest provides free live TV and $8 Wi-Fi. Frontier, Spirit, and Breeze have limited or no streaming, so download content beforehand.

Loyalty Programs and Credit Card Strategies

If you fly from ONT more than a few times a year, joining an airline’s frequent flyer program and pairing it with a co-branded credit card can erase bag fees and priority boarding. For Southwest, the Rapid Rewards Priority card offers a $75 annual travel credit and 7,500 anniversary points. Delta’s Gold SkyMiles card includes a free first checked bag and priority boarding. Alaska’s credit card gives a companion fare from $122 ($99 plus taxes and fees) each year—ideal for round-trip flights from ONT to Seattle. Even budget airline Frontier’s credit card offers Discount Den membership and a free carry-on bag, which can make their flights truly cheap.

Airport Experience and Practical Tips for Fontana Travelers

Both airports are designed to be less burdensome than LAX, but a few insider tips can make your trip even smoother.

Driving and Parking

From central Fontana, ONT is a quick 15-20 minute drive via the I-10. Terminal 2 handles most international and Southwest flights; Terminal 4 serves American, Delta, United, and others. Parking: hourly lots are next to the terminals ($3 per 30 minutes), daily lots are a short walk away ($19/day), and economy lots ($15/day) connect via free shuttle. SBD is about 15 minutes north via I-10 and I-215. The surface lot directly opposite the terminal is free when space is available, a huge money-saver for weekend trips.

Security and Expedited Screening

ONT’s security wait times are typically under 10 minutes, but can reach 15-20 minutes during early morning peak hours. Enroll in TSA PreCheck ($78 for five years) to keep it under 5 minutes and leave your shoes on. CLEAR is also available at ONT for biometric fast lanes. At SBD, the line is usually nonexistent, so PreCheck is less necessary but still accepted.

Airline Lounges and Amenities

ONT does not have dedicated airline lounges, but the terminal gate areas are spacious with ample charging stations. A USO lounge in Terminal 2 serves active military and their families. The airport’s Visitor Pass Program allows non-ticketed guests to go through security to shop or eat with departing travelers—something LAX doesn’t offer. Dining options include Coffee Bean & Tea Leaf, Carl’s Jr., and a sit-down bar. SBD’s terminal offers a small café, vending machines, and comfortable seating. Both airports provide free Wi-Fi.

When to Book and How to Get the Best Fare

Flight pricing from both airports follows typical patterns: book at least 3-4 weeks in advance for domestic trips, and avoid flying on Fridays and Sundays when prices peak. Southwest releases its schedule in batches, and the lowest fares often appear as soon as flights become available—set a fare alert. Frontier and Spirit run frequent sales, with base fares dipping below $20 on some routes if you can travel midweek. Breeze’s dynamic pricing rewards early booking; its “Nice” fares on new routes often launch with introductory prices under $50. Also consider package deals: sometimes booking a Frontier or Spirit flight + hotel on a site like Expedia yields a lower total cost than booking separately.

Making the Smartest Choice for Your Next Flight

Fontana’s unique position between a full-service hub and a niche budget terminal gives you the flexibility to match the journey to the trip. For business travel, connections to the East Coast, or a vacation with checked luggage, Ontario International and carriers like Southwest, Delta, or United are your best bet. For a minimalist weekend escape where every dollar counts, San Bernardino International and Breeze Airways deliver astonishing value and zero hassle. Factor in the total cost—ticket, bags, parking, and your time—and you’ll consistently find a departure that feels like a win. By knowing the route maps, fee structures, and loyalty tricks of each airline, a flight from Fontana can be as easy as packing a bag and driving ten minutes to a low-stress terminal.
