Best Airlines Flying from Gilbert Arizona Airport for Convenient and Reliable Travel Options

The Two Airports That Serve Gilbert, Arizona

Gilbert may not have a commercial runway inside town limits, but the community enjoys rapid access to two major aviation gateways. Phoenix-Mesa Gateway Airport (AZA) sits just east in Mesa, about a ten‑to‑fifteen‑minute drive from downtown Gilbert. For a wider network and international connections, Phoenix Sky Harbor International Airport (PHX) lies roughly twenty‑five to thirty‑five minutes northwest via the Loop 202 and Interstate 10. Together, these two airports deliver a blend of budget‑friendly nonstop options and full‑service global reach. Knowing which airlines fly from each—and what they do best—lets you book with confidence, save money, and trim unnecessary travel friction.

The ideal carrier depends entirely on your destination, budget, and personal priorities such as assigned seating, loyalty perks, or schedule frequency. At Mesa Gateway, you will find a compact terminal dominated by ultra‑low‑cost airlines that thrive on direct leisure routes. At Sky Harbor, the roster includes nearly every major U.S. airline plus international flagships, giving you immense flexibility. This guide breaks down the standout carriers at both airports, highlights their most popular routes, and arms you with strategies to secure the best value on every trip.

Phoenix-Mesa Gateway Airport (AZA): The Budget Powerhouse Next Door

Phoenix-Mesa Gateway Airport has evolved from a former Air Force base into a thriving commercial facility that now handles millions of passengers annually. For Gilbert residents, it is the default departure point for affordable domestic getaways. The single‑terminal layout means you can walk from the economy lot to security in minutes, and the limited number of gates translates to quick boarding and deplaning. The food and retail choices are modest compared to a hub, but travelers consistently praise the airport’s straightforward, low‑stress atmosphere.

Two budget‑focused airlines form the backbone of Gateway’s schedule, with occasional seasonal service from a third. All three rely on an à la carte pricing model: you pay a low base fare and then add only the services you actually need. If you can pack light and plan ahead, round‑trip tickets under $100 are routine.

Allegiant Air: The Homegrown Champion

Allegiant Air is, by a wide margin, the dominant carrier at Mesa Gateway. The airline bases aircraft here and operates an expanding network of nonstop flights to small and mid‑sized cities that larger carriers often ignore. Rather than funneling passengers through a traditional hub, Allegiant focuses on point‑to‑point routes that connect two leisure‑oriented destinations. That means you are far more likely to see a direct flight to Fargo, Provo, or Appleton than to a giant corporate center.

Popular Allegiant destinations from Mesa Gateway include Las Vegas, Denver, Los Angeles, Bellingham, Cedar Rapids, Sioux Falls, Grand Rapids, and dozens of other towns across the Midwest, South, and West. The airline adjusts its schedule seasonally, adding extra flights to colder climates in winter and outdoor hotspots in summer. Its reliability has improved markedly in recent years, and the all‑Airbus fleet now features more comfortable slimline seating than the older MD‑80 series it retired. Allegiant also sells vacation packages that bundle flights, hotels, and rental cars—often at significant savings over booking each component separately. You can view routes, package deals, and current fare sales directly on the Allegiant Air website.

Frontier Airlines: Ultra‑Low Competition That Benefits You

Frontier Airlines joined the Mesa Gateway lineup several years ago and has steadily increased its presence. Recognizable by its “Low Fares Done Right” slogan and the animals painted on its aircraft tails, Frontier provides another layer of nonstop destinations including Denver, Las Vegas, San Francisco, and Chicago. Its network often complements Allegiant’s, giving Gilbert travelers more schedule choices and the kind of price competition that crushes fares.

Frontier operates modern Airbus A320‑family jets with slimline seats and charges extra for everything beyond a small personal item. Joining the Discount Den membership program unlocks even lower member‑only fares and helpful perks like family pooling. Frontier’s Denver hub also serves as a connection point to dozens of additional U.S. cities, though most passengers departing from Mesa Gateway stick with the nonstop flights. For route maps, fare specials, and Discount Den details, visit the Frontier Airlines site.

Seasonal Additions: WestJet and Sun Country

During winter months, Canadian carrier WestJet often launches nonstop links between Mesa Gateway and cities such as Calgary or Edmonton, giving snowbirds a direct path to the Arizona sun. Sun Country Airlines has also tested seasonal flights to Minneapolis‑St. Paul. These routes may not run year‑round, but they add valuable connectivity for specific trips. Checking the airport’s official website periodically is the simplest way to catch new seasonal launches before they sell out.

Phoenix Sky Harbor International Airport (PHX): Full‑Service Powerhouse with Global Reach

When your travel plans require a flight to New York, Seattle, Miami, London, or Tokyo, Phoenix Sky Harbor is the answer. Situated just west of downtown Phoenix, Sky Harbor is the busiest airport in Arizona and a major hub for two of the nation’s largest airlines. The drive from Gilbert usually takes twenty‑five to thirty‑five minutes, and the airport’s extensive ground transportation options—ride‑share, light rail, shuttles, taxis, and on‑site parking—make early morning departures manageable even if you are not a morning person.

Sky Harbor is split between Terminal 3 and the enormous Terminal 4, linked by a free automated train. The sheer number of daily departures means you have tremendous flexibility. If you miss a flight or your plans suddenly change, there is almost always another option leaving within a few hours.

American Airlines: The Hub Giant

American Airlines operates its largest western hub at Phoenix Sky Harbor, offering nonstop service to more than ninety domestic cities plus destinations in Mexico, Canada, and Central America. For Gilbert residents, American is the default choice for business travel, mileage runs, and any itinerary that demands a wide range of departure times. The airline’s schedule includes hourly shuttles to Los Angeles, Dallas‑Fort Worth, and Chicago, along with multiple daily flights to practically every major U.S. market.

Because Phoenix is a hub, connecting to smaller regional cities is seamless. Even if your final destination is Flagstaff, Yuma, or Durango, American’s regional jets make the link efficient. The AAdvantage loyalty program and co‑branded credit cards unlock upgrades, lounge access, and free checked bags, which can offset many of the ancillary fees that budget carriers charge. To explore full route lists and award availability, use the American Airlines booking tool.

Southwest Airlines: Flexible Policies and Family‑Friendly Value

Southwest Airlines is the other giant at Sky Harbor, and its long‑standing presence in Phoenix makes it a top pick for families, leisure travelers, and anyone who values simplicity. Southwest’s no‑change‑fee policy, two free checked bags, and famously friendly cabin crews build deep loyalty. The airline flies nonstop from Phoenix to more than sixty cities, with heavy frequencies to California, Texas, the Midwest, and the Pacific Northwest.

Southwest uses an open seating model—a welcome perk if you check in early and snag a great spot, but a potential frustration if you board last. Paying for EarlyBird Check‑In or using a Southwest credit card that includes upgraded boarding can secure a better position in line. The Rapid Rewards program remains one of the most valuable in the industry, with points that maintain consistent value and no blackout dates on award seats.

Other Valuable Sky Harbor Carriers

Beyond the two dominant airlines, several other carriers round out Sky Harbor’s lineup and can be excellent choices from Gilbert depending on your destination.

Delta Air Lines — Nonstop service to Atlanta, Minneapolis, Salt Lake City, and Seattle, with smooth connections across the globe through those hubs. Delta’s premium cabins and reliable operation make it a strong pick for longer flights or anyone who values a consistent on‑time product.
United Airlines — Flights to its hubs in Denver, Chicago, Houston, and San Francisco, providing another path to domestic and international points. United’s network complements American and Delta nicely, particularly if you are heading to the Mountain West or Asia.
Spirit Airlines — Brings its ultra‑low fares into Sky Harbor, connecting Phoenix with Las Vegas, Dallas, Detroit, Fort Lauderdale, and other cities. While not based at Mesa Gateway, Spirit’s presence at PHX serves Gilbert bargain hunters willing to drive the extra fifteen minutes to save cash.
Alaska Airlines, JetBlue, Hawaiian Airlines, and British Airways — These carriers add nonstop options to the West Coast, Northeast, Hawaii, and London, respectively. They are excellent for specific trips and inject meaningful competition that helps keep everyone’s fares in check.

Gateway vs. Sky Harbor: A Side‑by‑Side Comparison

Choosing between Phoenix-Mesa Gateway and Phoenix Sky Harbor usually comes down to two factors: whether your destination is served nonstop, and how you value time versus amenities. The table below highlights the key differences, but the right answer may change from trip to trip.

Factor	Phoenix-Mesa Gateway (AZA)	Phoenix Sky Harbor (PHX)
Drive time from Gilbert	10–15 minutes	25–35 minutes
Airlines	Allegiant, Frontier, occasional WestJet/Sun Country	American, Southwest, Delta, United, Spirit, Alaska, JetBlue, British Airways, and more
Typical fare structure	Ultra‑low base fares; everything else à la carte	Mixed: deep‑discount basics to full‑service premium
Nonstop destinations	~50 seasonal and year‑round domestic cities	100+ domestic and international cities
Terminal experience	Single terminal, quick security, basic food and shops	Two terminals, extensive dining, retail, airline lounges
Parking cost	Generally lower, ample surface lots	Higher, with garage and economy lot options
Ride‑share pickup	Designated zone steps from baggage claim	Multiple zones per terminal, clearly marked

If your destination is served nonstop by Allegiant or Frontier and you are comfortable with an à la carte model, Mesa Gateway is the unequivocal choice. You will spend less time traveling to the airport and more time enjoying your trip. If you need a broader schedule, business‑class seating, or international connections, Sky Harbor’s additional drive is a small price to pay for the world of options it unlocks. Many Gilbert households regularly use both airports, selecting the best fit for each trip.

Baggage Policies and Hidden Costs: What Every Gilbert Traveler Should Know

With the mix of low‑cost and full‑service airlines serving the area, understanding your true out‑the‑door cost is essential. The advertised fare is rarely the final price once bags and seat assignments are added.

Allegiant and Frontier both charge for full‑size carry‑ons and checked luggage, with fees that increase dramatically if you wait until the day of departure. A personal item that fits under the seat is always free. Booking bags online at the same time as your ticket can cut those fees in half. Spirit Airlines follows a similar model at Sky Harbor. If you are traveling with only a backpack, these carriers can be the cheapest option by far.

Southwest Airlines stands out with its two free checked bags per passenger, no change fees, and no charge for a standard carry‑on. For families hauling strollers, car seats, and suitcases, this policy alone often justifies a moderately higher base fare. American, Delta, and United typically allow a carry‑on and a personal item on most domestic routes, though basic economy tickets may restrict this. Baggage fees on these network carriers usually apply to checked luggage unless you hold elite status or a co‑branded credit card.

Always add up the total cost—fare + seat selection (if you care) + baggage fees—before comparing airlines. A $39 Allegiant ticket can balloon to $120 once a carry‑on and checked bag are added, while a $119 Southwest ticket might already cover everything. Use the airline’s own bag fee calculator during the booking process to see the real number.

How to Find the Best Deals on Flights from Gilbert

Airline pricing is dynamic, but a handful of consistent strategies will help you lock in lower fares regardless of which airport you choose. Flexibility is the single most powerful tool in your arsenal.

Leverage Low Fare Calendars and Flexible Date Searches

Most booking platforms and airline websites display a low fare calendar that lets you scan prices across an entire month in seconds. Shifting your departure or return by just one day can sometimes cut the fare in half. Tuesdays, Wednesdays, and Saturdays are typically the cheapest days to fly domestically, while Fridays and Sundays carry a premium. Use tools like Google Flights to view six‑month fare trends and identify the cheapest month to travel your preferred route.

Set Price Alerts and Book at the Right Window

Signing up for price alerts from Google Flights, Kayak, or Hopper eliminates the need to repeatedly check fares manually. You will receive instant notifications when a price drops, which is especially valuable for popular routes out of Mesa Gateway or Sky Harbor that frequently see fare wars. Generally, booking domestic flights three to six weeks in advance yields the lowest fares, though Allegiant and Frontier sometimes release their deepest discounts three or more months ahead of travel. For peak holiday periods, however, the best advice is to book as soon as you know your dates—procrastination rarely pays off during Christmas or spring break.

Consider Mixing Carriers and Airports

You are not tied to a single airline for your round trip. Purchasing two one‑way tickets on different carriers can unlock significant savings. For example, flying Allegiant out of Mesa Gateway to a city and returning via Southwest into Sky Harbor could be cheaper than any round‑trip itinerary on one airline. Just remember that you will need to position a car or arrange separate transportation if you park at different airports. This strategy works best when you have a flexible schedule and a ride that can drop you off or pick you up at either facility.

Use Airline Rewards and Travel Credit Cards Wisely

If you travel often, concentrating your flights on one or two loyalty programs—such as American’s AAdvantage or Southwest’s Rapid Rewards—can generate free flights and status perks far faster than scattering your miles. A co‑branded credit card often includes a free checked bag, priority boarding, and anniversary travel credits that substantially offset the fees budget carriers charge. The right general‑purpose travel rewards card also earns flexible points that can be transferred to multiple airline partners, giving you a backdoor way to book premium cabins or off‑peak awards even on carriers that do not serve your home airport directly.

Getting to the Airport and Navigating the Logistics

A smooth trip starts with a well‑planned journey to the terminal. Gilbert travelers enjoy reliable ride‑share services, a variety of nearby hotels, and mostly pleasant desert weather year‑round.

Both airports are well served by Uber and Lyft. A ride‑share trip from central Gilbert to Mesa Gateway typically costs $15–$25 and takes ten to fifteen minutes. The trip to Sky Harbor runs $30–$45 and usually clocks in around half an hour. Designated pick‑up and drop‑off areas are clearly marked at each terminal. If you prefer to drive yourself, Mesa Gateway’s economy parking is an affordable long‑term option with prices well below Sky Harbor’s garages. Sky Harbor offers both covered parking and an Economy Lot with a free shuttle bus. The official Gateway Airport site lists current parking rates and real‑time availability, while Sky Harbor’s website offers similar tools.

Hotels with Park‑and‑Fly Packages

Early morning flights or late‑night arrivals can make staying near the airport a smart move. Hotels clustered around both facilities include familiar brands such as Hampton Inn, Residence Inn, Holiday Inn Express, and Courtyard by Marriott. Many offer park‑and‑fly packages that let you leave your vehicle for the duration of your trip at a reduced rate, often cheaper than airport parking alone. For a more upscale pre‑ or post‑flight experience, the resorts of Scottsdale and Tempe are within a twenty‑minute drive of Sky Harbor.

Desert Climate and What to Pack

Gilbert and the surrounding Valley of the Sun experience dramatic temperature swings between seasons. Summer, from June through September, routinely brings highs above 105°F (40°C). Airports are air‑conditioned, but if you are walking between terminals or waiting for a ride, wear lightweight, breathable clothing, sunscreen, and a hat. Winter is mild and pleasant, with daytime highs in the 60s and 70s °F (15–25°C) and cooler nights. Spring and fall are the sweet spots for travel, offering perfect weather for outdoor patios and sightseeing. No matter the season, carry a water bottle—the desert dryness can sneak up on you even when temperatures feel moderate.

Your Perfect Flight Strategy: A Quick Decision Guide

After watching Gilbert’s aviation options expand, the conclusion is straightforward: there is no single best airline, but there is a clear best airline for each trip. Use this quick guide to match your priorities with the right carrier and airport.

You want the absolute lowest fare and a direct flight to a smaller city. Choose Allegiant Air from Phoenix-Mesa Gateway. Pack light, bring only a personal item, and pay only for what you need.
You need low fares but a major city like Chicago or Denver. Compare Allegiant and Frontier at Mesa Gateway first, then check Spirit and Southwest at Sky Harbor. Factor in baggage costs, not just the headline fare.
You require maximum schedule flexibility, business‑class service, or international connections. American Airlines from Sky Harbor is the strongest choice, followed by Southwest if you value bags and no change fees over premium seating.
You are traveling to Canada in the winter. Watch for seasonal WestJet nonstops at Mesa Gateway; otherwise, connect through Sky Harbor on American or United, which offer robust Canadian schedules.
You want a balance of price, service, and free luggage. Southwest at Sky Harbor offers the best mix of low fees, two free checked bags, and frequent departures to popular destinations.

By understanding the strengths of each carrier and airport serving the Gilbert area, you can avoid overpaying, reduce travel stress, and start exploring the country—and the world—with confidence. Visit the airline websites, set those price alerts, and take advantage of the convenient, reliable flights that this corner of Arizona now delivers.
