Flying Out of the Wrong Airport Could Be Costing You Hundreds — Try These 15 Instead
Here's a travel truth that most booking sites won't tell you: where you depart from matters just as much as where you're going. Millions of American travelers default to the closest big-name airport — LAX, JFK, O'Hare — without ever checking whether a regional airport 45 minutes away might save them $200 or more on the exact same trip.
At FreeFlights, we're all about rethinking the obvious. So we put together this guide to 15 underrated US airports where airfare consistently runs 40 to 60 percent cheaper than nearby major hubs. Grab your zip code and see if one of these is within driving distance.
1. Burbank Bob Hope Airport (BUR) — Los Angeles Area
Why it's cheaper: BUR serves the same greater LA metro as LAX but handles a fraction of the traffic. Southwest dominates here, and their low-cost model keeps prices competitive.
Sweet spots: Las Vegas, Phoenix, San Francisco, Denver
Pro tip: Parking and ground transportation at Burbank are dramatically easier (and cheaper) than LAX. Factor that into your total savings.
2. Long Beach Airport (LGB) — Southern California
Why it's cheaper: Another LAX alternative, Long Beach is a small, relaxed airport that regularly offers JetBlue deals at prices that make LAX tickets look absurd.
Sweet spots: New York (JFK), Boston, Fort Lauderdale
Pro tip: The airport is tiny enough that you can arrive 45 minutes before your flight and still make it. That alone is worth something.
3. Providence T.F. Green Airport (PVD) — New England
Why it's cheaper: Sitting just an hour south of Boston, Providence is one of the East Coast's best-kept secrets. Southwest flies heavily here, and fares are routinely 30-50% below Logan.
Sweet spots: Florida destinations, Chicago, Baltimore
Pro tip: Boston residents who drive to PVD instead of using Logan often save enough to cover gas, parking, and a decent meal before the flight.
4. Manchester-Boston Regional Airport (MHT) — New Hampshire
Why it's cheaper: Less than an hour north of Boston, MHT benefits from low overhead and carrier competition. Spirit and Southwest keep fares lean.
Sweet spots: Orlando, Fort Lauderdale, Las Vegas
Pro tip: Free parking options near MHT make it even more economical compared to the parking nightmare at Logan.
5. Stewart International Airport (SWF) — Hudson Valley, NY
Why it's cheaper: About 60 miles north of New York City, SWF is served by Allegiant and offers some of the lowest fares available to anyone in the tri-state area willing to make the drive.
Sweet spots: Florida destinations, Myrtle Beach, Savannah
Pro tip: Allegiant's model means fewer flight options, but the savings on popular leisure routes can be jaw-dropping.
6. Midway International Airport (MDW) — Chicago
Why it's cheaper: O'Hare gets all the glory, but Midway — Chicago's other airport — is Southwest's Midwest stronghold. Fares here are consistently lower, and the airport is easier to navigate.
Sweet spots: Nashville, Denver, Phoenix, Las Vegas
Pro tip: Midway is actually closer to downtown Chicago than O'Hare. It's not just cheaper — it's more convenient.
7. Oakland International Airport (OAK) — San Francisco Bay Area
Why it's cheaper: SFO charges a premium for everything. Oakland, just across the bay, serves many of the same destinations at significantly lower prices — and Southwest has a major presence here.
Sweet spots: Los Angeles, San Diego, Las Vegas, Seattle
Pro tip: BART connects Oakland Airport to the broader Bay Area, so you don't even need a car.
8. San Jose Mineta International Airport (SJC) — Silicon Valley
Why it's cheaper: A third Bay Area option, SJC is often overlooked but regularly offers deals that undercut both SFO and OAK on certain routes.
Sweet spots: Denver, Phoenix, Dallas, Chicago
Pro tip: If you're traveling for business in the South Bay, this is almost always the smarter pick.
9. Fort Lauderdale-Hollywood International Airport (FLL) — South Florida
Why it's cheaper: Miami International gets the marketing, but FLL — just 30 miles north — is a budget carrier hub. Spirit calls it home, and Southwest has a heavy presence too.
Sweet spots: New York, Chicago, Boston, Philadelphia
Pro tip: FLL is often the cheapest airport in the entire Southeast for northbound routes. If you're flying out of South Florida, always check it first.
10. Baltimore/Washington International Airport (BWI) — DC Metro Area
Why it's cheaper: Reagan National and Dulles both serve Washington DC, but BWI — about 30 miles from DC — is where Southwest lives. Fares here are reliably lower across the board.
Sweet spots: Chicago, Nashville, Denver, Las Vegas
Pro tip: MARC train service connects BWI to DC's Penn Station, making it accessible without a car.
11. Sanford International Airport (SFB) — Central Florida
Why it's cheaper: Everyone flies into Orlando International (MCO). Sanford sits 30 miles north and is served primarily by Allegiant, with prices that sometimes seem almost fictional.
Sweet spots: Midwest and Mid-Atlantic cities, smaller regional markets
Pro tip: If your Florida trip is about the beach or theme parks equally, Sanford is perfectly positioned — and the drive to Disney or the Gulf Coast is the same either way.
12. Islip MacArthur Airport (ISP) — Long Island, NY
Why it's cheaper: New Yorkers who live on Long Island often drive into JFK or even LaGuardia. ISP, right in their backyard, offers Southwest and Frontier fares that are a fraction of those prices.
Sweet spots: Fort Lauderdale, Orlando, Myrtle Beach
Pro tip: Skip the nightmare of getting to JFK and check ISP first. You might be shocked.
13. Raleigh-Durham International Airport (RDU) — North Carolina
Why it's cheaper: RDU isn't tiny, but it punches well above its weight on deals. It's become a budget carrier favorite, and the Research Triangle's growing population means airlines are competing hard for passengers.
Sweet spots: New York, Chicago, Denver, Miami
Pro tip: RDU frequently surfaces in our FreeFlights deal alerts — it's a legitimately great departure airport for Southeast travelers.
14. Tucson International Airport (TUS) — Arizona
Why it's cheaper: Phoenix Sky Harbor gets most of Arizona's air traffic, which means Tucson — 90 miles south — sees less competition but also less demand, keeping prices surprisingly low.
Sweet spots: Los Angeles, Dallas, Chicago, Denver
Pro tip: If you're in southern Arizona or crossing from New Mexico, TUS can save you real money versus the drive to Phoenix.
15. Spokane International Airport (GEG) — Pacific Northwest
Why it's cheaper: Seattle-Tacoma International is the Pacific Northwest's dominant hub, and its prices reflect that dominance. Spokane, three hours east, offers dramatically lower fares for travelers in eastern Washington, northern Idaho, and western Montana.
Sweet spots: Las Vegas, Denver, Los Angeles, Phoenix
Pro tip: Alaska Airlines and Southwest both serve GEG competitively. For anyone in the Inland Northwest, this should always be the first search.
How to Build Your Search Strategy Around Alternative Airports
The best approach is simple: whenever you're planning a trip, don't just search your default airport. Search every airport within a 90-minute drive and compare totals — including parking, gas, and ground transportation. Tools like Google Flights let you search multiple nearby airports at once, making this comparison fast and easy.
Better yet, bookmark FreeFlights and check our deal alerts. We track prices across hundreds of US airports — including all the regional ones the big booking sites tend to bury — so you never have to wonder if you're missing a better deal just down the highway.
The airport you've always flown out of might be the most expensive decision you make all trip.
