Travelers departing from Pomona, California, have convenient and affordable air travel options right in their backyard — even though the city itself no longer hosts a commercial passenger terminal. The primary gateway is Ontario International Airport (ONT), located roughly 10 miles west of downtown Pomona along the CA-60 and I-10 corridors. This compact, easy-to-navigate airport punches well above its weight, offering nonstop flights on a diverse mix of full-service, low-cost, and ultra-low-cost carriers to destinations across the United States and beyond. For those willing to consider a slightly longer drive, Los Angeles International Airport (LAX) and John Wayne Airport (SNA) provide additional international and transcontinental routes, but for most Pomona travelers, ONT remains the clear choice for its speed, affordability, and rising roster of airlines. This guide examines the best airlines flying from the Pomona area, comparing included perks, add-on fees, route networks, and the real-world value each one delivers.

Southwest Airlines: Two Free Checked Bags and No Change Fees from Ontario

Southwest is the dominant carrier at Ontario International Airport by passenger count, and its customer-first model resonates with both leisure and business travelers. Every ticket includes two free checked bags, a full-size carry-on, and a personal item. Change and cancellation fees simply don’t exist — if your plans shift, you receive a travel credit to use on a future flight without penalty. This built-in flexibility alone can save hundreds of dollars for families or anyone juggling uncertain schedules.

From ONT, Southwest flies nonstop to a mix of business and leisure markets, including Las Vegas, Phoenix, Denver, Oakland, Sacramento, San Jose, and Dallas Love Field. Seasonal and peak-period additions frequently extend to Orlando, Chicago Midway, and Houston Hobby. The airline’s point-to-point model means many other cities are reachable with a single stop and often without changing aircraft. Southwest’s Rapid Rewards loyalty program is a favorite because points never expire and there are no blackout dates, making it easy to redeem for short hops or cross-country itineraries.

The drive from Pomona to Ontario typically takes 15 to 25 minutes via CA-60 West or I-10 West. Southwest operates out of Terminal 4, where security screening times are generally short, especially for the early-morning bank of departures. Booking directly at Southwest.com unlocks the airline’s “Wanna Get Away” fares, which regularly dip below $49 one-way to Las Vegas and under $80 to the Bay Area. EarlyBird Check-In is an optional add-on that automatically secures a better boarding position, worth considering if you want to avoid a middle seat on full flights.

Frontier Airlines: Ultra-Low Base Fares When You Travel Light

Frontier Airlines anchors the ultra-low-cost end of the spectrum at Ontario, using a base fare that covers only a small personal item. The airline’s nonstop roster from ONT includes Denver, Las Vegas, Orlando, and Phoenix, with one-stop connections to dozens of additional cities via its Denver hub. During promotional windows, fares as low as $29 one-way appear, though they require careful planning to keep the final price that low.

Everything beyond the seat and under-seat bag is à la carte: a carry-on bag starts around $39 each way when added during booking, checked bags from $34, and seat selection from $5. Onboard beverages and snacks are also for sale. The optional Discount Den membership — roughly $60 per year — unlocks exclusive lower fares and companion-fly rates, making it a good deal for anyone who plans to fly Frontier two or more times round-trip. The airline markets a “WORKS” bundle that includes a carry-on, checked bag, seat selection, and trip flexibility, but once you add those perks, the price often climbs close to or above Southwest’s all-inclusive ticket, so it’s best suited to travelers who truly don’t need the extras.

Pomona residents who can pack light and check in online will get the maximum value out of Frontier. The key is to pay for any required bags and seat assignments at the time of initial booking, as airport-counter add-ons come with a steep upcharge. For a quick weekend escape with just a backpack, Frontier’s bare-bones pricing is among the cheapest transportation money can buy.

Spirit Airlines: Dollar Fares and a Customizable Experience

Spirit Airlines competes directly with Frontier on the ultra-low-cost model, often offering introductory one-way fares that drop into the $20s on heavily contested routes like Ontario–Las Vegas. In addition to LAS, Spirit flies nonstop from ONT to Dallas-Fort Worth, San Jose, and Oakland, with connecting service reaching the East Coast, Caribbean, and Latin America through its Fort Lauderdale and Dallas gateways.

Spirit’s Bare Fare includes only a personal item, but the airline has refined its bundling strategy in recent years. The “Go Big” fare tier includes the equivalent of a premium seat at the front of the plane, a checked bag, a carry-on, priority boarding, and complimentary snacks and drinks — essentially a domestic first-class lite experience on a budget carrier. “Go Comfy” unlocks extra legroom and a carry-on, while “Go Savvy” provides a standard seat selection and a carry-on. These options let travelers pick a level of service that matches their trip, rather than paying for individual items.

The Spirit Saver$ Club, available for an annual fee, gives members access to discounted fares and add-ons. The airline also runs flash sales that cut prices by up to 75%, so signing up for the Spirit email list is a smart move for Pomona bargain hunters. When comparing Spirit to Southwest, run the math on what you’ll actually bring: a round trip with a carry-on and one checked bag can quickly cost $100 more than Southwest’s all-in fare, but a solo traveler with only a backpack might save $50 or more. Flexibility on travel days helps too — midweek Spirit flights routinely undercut weekend prices by half.

United Airlines: Premium Cabins and Global Reach from Ontario

United Airlines is the go-to for Pomona travelers who need a business-class cabin, international connections, or a full-service experience. From Ontario, United operates multiple daily flights to its major hubs in Denver, Houston Intercontinental, and San Francisco. Through those gateways, you can reach hundreds of cities across the Americas, Europe, Asia, and the South Pacific with a single stop and through-checked luggage.

On domestic segments, United mixes mainline Airbus and Boeing jets with regional aircraft, all offering a First Class cabin with wider seats, dedicated overhead bin space, and enhanced meal service on longer flights. Standard Economy includes a carry-on and personal item, seat selection, and the ability to check a bag for a fee (usually $35 for the first bag). Basic Economy strips the carry-on and advance seat assignment, similar to a budget-fare model, but still allows a personal item and typically earns MileagePlus miles at a reduced rate. For travelers with Premier status, the equation improves: complimentary upgrades on domestic routes, priority boarding, and lounge access when flying internationally become real differentiators.

United’s pricing on routes from ONT is often higher than that of its low-cost competitors, but the value proposition strengthens when you need a carry-on, checked luggage, or a seat assignment — all bundled in standard Economy — or when you’re connecting onto an intercontinental flight. The ability to book a fully refundable fare also gives business travelers and last-minute planners peace of mind that budget carriers don’t always match.

American Airlines: A Legacy Option with One-Stop Reach

American Airlines maintains a steady presence at Ontario through its American Eagle regional network. Direct flights head to American’s hubs in Dallas/Fort Worth and Phoenix Sky Harbor, where passengers can connect to the airline’s vast domestic and international network, including service to Europe, Asia, and South America. While American does not offer the same frequency from ONT as it does from LAX, the flights are timed to make connections smooth, and the airport’s short security lines make the originating leg painless.

Mainline flights are occasionally deployed during peak travel periods, but most services are aboard Embraer or Canadair regional jets with a two-class cabin. First Class on these routes provides a larger seat, pre-departure beverage service, and priority handling, while Main Cabin Extra offers extra legroom seating as an upgrade. Standard Main Cabin fares include a carry-on, a personal item, and seat selection; Basic Economy mirrors United’s restrictions with no carry-on and no advanced seat selection.

American’s AAdvantage loyalty program is especially appealing for Pomona travelers who also fly internationally or who hold an American Airlines co-branded credit card, which can unlock free checked bags and priority boarding. Fares from Ontario are competitive with United on overlapping hub routes, and during sales, round-trip tickets to the East Coast or the Midwest can dip below $200. When compared against ultra-low-cost carriers, American’s network reliability and the option to purchase Main Cabin Extra seating often win over travelers who value a more traditional flying experience.

Delta Air Lines: Connecting Pomona to the Southeast and Beyond

Delta Air Lines serves Ontario with nonstop flights to its key hub at Salt Lake City, offering onward connections to the Pacific Northwest, Midwest, Southeast, and East Coast. This route provides an alternative to the Denver and Phoenix hubs used by other carriers and can reduce overall travel time to destinations like Portland, Boise, or Atlanta. Delta also occasionally adds seasonal service to Minneapolis-St. Paul, though that route may not operate year-round.

Delta’s product on the ONT-SLC route uses a mix of Airbus and Boeing aircraft with a First Class cabin, Comfort+ extra-legroom seating, and Main Cabin. Standard Main Cabin fares include a carry-on and personal item, while Basic Economy limits you to a personal item and seats assigned at the gate. Comfort+ seats add up to four inches of extra legroom, dedicated overhead bin space, and complimentary beer, wine, and snacks on longer flights — a nice middle ground when you don’t need the full First Class price.

For Pomona-based travelers, Delta offers several advantages: the airline consistently ranks high for on-time performance and customer satisfaction, and its SkyMiles program provides award redemptions with no blackout dates on Delta-operated flights. If you carry a Delta Amex card, you can receive a free checked bag and priority boarding, effectively eliminating the fee gap with Southwest on a per-trip basis. While Delta may not always offer the lowest base fare on the Ontario-Salt Lake City corridor, the airline’s reliability and the comfort of Comfort+ often make it worth the premium.

Breeze Airways: New Point-to-Point Service with a Friendly Twist

Breeze Airways is the newest scheduled airline at Ontario, focusing on nonstop point-to-point routes that bypass traditional hubs. Breeze aims for a simplified, people-first experience: the “Nice” fare includes a carry-on, “Nicer” bumps you to extra-legroom seating with a checked bag, priority boarding, and a snack bundle, and “Nicest” — available on longer flights operated by Airbus A220 aircraft — delivers a domestic first-class-style seat with 39 inches of pitch and a complimentary meal.

From ONT, Breeze currently connects Pomona travelers to destinations such as Provo, Utah (serving the Salt Lake City metro area) and San Francisco, with seasonal additions announced regularly. The airline’s expanding route map is worth monitoring at the Breeze website, as new routes can open up fresh leisure options. Because Breeze often uses secondary airports that charge lower landing fees, fares can be surprisingly affordable even at the Nicer tier.

Breeze’s no-change-fee policy, transparent pricing, and straightforward loyalty program (BreezePoints, which rewards spending rather than distance) make it an attractive alternative for leisure travelers who want a step up from the ultra-low-cost model without paying legacy-carrier prices. The airline’s reliance on smaller airports also means shorter walks and less congestion, adding to the overall sense of ease.

Comparing Amenities and Fees Across Carriers at Ontario International

The cost you see in the initial search result rarely tells the full story. To determine which airline gives you the best value from Pomona, you need to look at what is included in the base fare and what you will actually use. The table below summarizes the major differentiators for the carriers discussed.

  • Southwest: Two free checked bags, free carry-on, free seat selection at check-in. No change or cancellation fees. Seats are unassigned; boarding order determined by check-in time or EarlyBird purchase.
  • Frontier: Personal item only included. Carry-on from $39 each way, checked bag from $34. Seat selection from $5. Discount Den membership $60/year.
  • Spirit: Personal item only. Carry-on from $37 each way, checked bag from $30. Seat selection from $1. Tiered bundles (Go Big, Go Comfy, Go Savvy) available. Saver$ Club membership extra.
  • United: Standard Economy includes carry-on plus personal item, seat selection, and first checked bag for $35. Basic Economy strips the carry-on and seat selection. No change fees on most fares except Basic.
  • American: Standard Main Cabin includes carry-on, personal item, and seat selection. First checked bag $30. Basic Economy: personal item only, no seat selection until check-in.
  • Delta: Standard Main Cabin: carry-on, personal item, seat selection. First checked bag $30. Basic Economy: personal item only, seat assigned at gate. Comfort+ offers extra legroom and premium drinks.
  • Breeze: “Nice” fare includes carry-on; “Nicer” adds a checked bag, extra legroom, priority boarding, and snacks; “Nicest” includes a premium seat and meal. No change fees.

For a solo traveler packing only a personal item, Spirit or Frontier will almost always produce the lowest final price. For a family of four with two checked bags each, Southwest’s all-in fare will frequently undercut the ultra-low-cost carriers by $150 or more round trip. Business travelers who need a carry-on, seat selection, and the option to cancel on short notice will find United, American, or Delta’s standard Economy fares more competitive when those services are bundled. Spend a few minutes running a sample booking on each airline’s website to see the final total — that’s the number that matters.

How to Find the Best Deals from Pomona: Direct Flights, Sales, and Flexible Tickets

Ontario’s route map is strongest on western leisure corridors, where competing airlines keep prices in check. Las Vegas is the busiest market, with Southwest, Frontier, and Spirit all vying for customers. Denver sees United and Frontier go head-to-head, while the Bay Area routes are split among Southwest, Spirit, and Breeze. Knowing which carriers fly which routes lets you target sales more effectively.

Use fare-tracking tools like Google Flights or the price calendar on Kayak to monitor fare trends and set alerts for price drops. If you need flexibility, filtering for “free cancellation” or “no change fees” will surface the best options — Southwest remains the standout here because the policy applies to every fare, while many other carriers now offer fee-free changes on all but Basic Economy tickets. Signing up for airline email newsletters is especially valuable with Spirit and Frontier, which frequently distribute promo codes that slash fares by 50% or more for a limited time.

When you find a fare you like, book directly through the airline’s website. This ensures you receive online-exclusive deals and avoids complications if you need to modify the trip later. As a rule of thumb, Tuesday and Wednesday flights out of ONT price 20–30% lower than Friday and Sunday departures, and early-morning or late-night options can shave off another 10–15%. For international trips that start with a connecting flight from Ontario, compare the total fare against what’s available from LAX — sometimes the longer drive is worth it for a nonstop overseas flight, especially when you account for the time and stress of a forced connection.

Getting from Pomona to Ontario International and Other Airports

Ontario International Airport is the natural first stop for any Pomona air traveler. The drive is straightforward: take CA-60 West or I-10 West and follow signs for Airport Drive. In average traffic, the trip takes 15 to 25 minutes, and even during peak commute times, it rarely exceeds 35 minutes. ONT’s parking is among the most affordable in Southern California, with economy Lot 5 charging around $14 per day and long-stay packages bringing the daily rate even lower. Ridesharing services like Uber and Lyft operate freely at ONT, with designated pickup zones directly outside Terminals 2 and 4. Several private shuttle companies also serve Pomona hotels for a flat rate.

For flights not offered from Ontario — such as intercontinental routes to Asia or Europe — Los Angeles International Airport (LAX) becomes an option, though it demands a considerably longer commitment. The drive from Pomona to LAX typically takes 50 to 75 minutes via I-605 and I-105, and you should budget at least two hours for parking, check-in, and security. Pre-booking a parking space online is highly recommended at LAX, as garages fill up quickly during holidays and summer months. John Wayne Airport in Orange County is another alternative for some domestic routes, but the drive time is similar to LAX and flight selection is more limited.

For those on a tight budget, a Metrolink train from Pomona Station can connect to the FlyAway bus at Union Station, which serves LAX directly. The total journey can stretch to two and a half hours, so it’s only practical if you have a generous time buffer. General aviation fields like Brackett Field and Cable Airport are located close to Pomona but cater exclusively to private and charter aircraft rather than scheduled commercial service. The vast majority of Pomona travelers will find Ontario International the most convenient and cost-effective gateway, with all the airline choices needed for domestic and nearby international travel.

Exploring Southern California for Inbound Passengers

While many Pomona residents head outbound for vacation, the airport’s location also makes it a handy arrival point for visitors eager to explore the Los Angeles region. Ontario International is just 40 minutes by freeway from downtown Los Angeles, Hollywood, and the beaches, meaning you can land, pick up a rental car, and be at your first attraction within an hour.

Start with the iconic Griffith Observatory for panoramic views of the Hollywood Sign and the LA Basin, then walk the Hollywood Walk of Fame and visit the TCL Chinese Theatre. Art enthusiasts can spend a full day at the Los Angeles County Museum of Art or the Getty Center, while music lovers should check the Hollywood Bowl calendar for an evening concert under the stars. For a taste of the city’s Mexican heritage, stroll through Olvera Street and sample authentic street food near Union Station. If you time your visit right, a drive along Mulholland Drive at sunset provides postcard-worthy vistas.

Closer to the airport, Ontario Mills offers an expansive outlet shopping experience, and the Toyota Arena hosts major concerts and sporting events just 20 minutes from the terminal. The San Bernardino Mountains are also a short drive east, making ONT an ideal gateway for ski trips or summer lake getaways. No matter what brings you to the area, Pomona’s strategic position means you can spend less time in traffic and more time enjoying Southern California’s diverse offerings.

Making the Right Choice for Your Next Trip from Pomona

Selecting an airline from the Pomona area comes down to the specifics of your trip. Southwest’s all‑inclusive pricing and fee‑free flexibility make it the default pick for travelers who value simplicity and hate surprise charges. Frontier and Spirit deliver the lowest possible price for the bag‑free minimalist, and their bundled tiers are worth a look when you want a little extra comfort without a full‑service premium. United, American, and Delta tie into global networks and offer a level of service and reliability that business travelers and international connectors rely on. And Breeze is carving out a niche with friendly, point‑to‑point service that skips the big‑hub hassle.

Before you book, map out what you’ll actually pack and how much flexibility your schedule needs. Then compare the final cart total across the airlines that fly your route — not just the headline fare. With Ontario International Airport just a quick drive from Pomona and a growing roster of carriers competing for your business, you have more power than ever to find a flight that fits both your itinerary and your wallet.
