Which Airlines Have Pilot Bases in Phoenix? (2026 Guide)

Phoenix Sky Harbor International Airport (PHX) has quietly become one of the most important crew hubs in the western United States. It's a hub for American Airlines and a crew base for Southwest and Frontier — and with Envoy Air's regional base added in 2022, PHX now offers pilots more domicile options than almost any other Southwest city. If you're weighing a move to the Valley of the Sun or just trying to figure out where your seniority number might take you, here's a current breakdown of who actually bases pilots in Phoenix, who just flies through, and what life looks like at each one.

Quick Answer: Airlines With Pilot Bases in Phoenix

As of 2026, three passenger airlines maintain true pilot crew bases at PHX:

• American Airlines — PHX is a major Airbus narrowbody base and one of American's largest western operations

• Southwest Airlines — one of Southwest's original crew bases, still active today

• Frontier Airlines — opened its PHX pilot base in November 2022

Two regional carriers also base pilots at PHX: Envoy Air, American's wholly-owned regional partner, which opened a crew and maintenance base there in 2022, and SkyWest Airlines, the largest independent regional in the U.S., which has run a PHX pilot domicile for decades, flying under multiple mainline codeshare brands. Several other major carriers — Delta, Alaska, JetBlue, United, Allegiant, Breeze, and Avelo — serve Phoenix with regular flights but don't currently domicile pilots there.

American Airlines

Phoenix has deep roots as an airline hub going back to America West, which was headquartered there before merging into US Airways and eventually American. Today PHX remains one of American's busiest focus cities, and it's an established Airbus narrowbody base, historically bidding A319, A320, and A321 family aircraft. American runs well over 300 daily departures from PHX, more than any other carrier at the airport, and Terminal 4 is effectively American's home turf in the Valley.

Southwest Airlines

Southwest has operated a Phoenix crew base since practically the early days of the airline, and it remains one of its 13 active domiciles today alongside cities like Dallas, Denver, and Las Vegas. Because Southwest flies an all-Boeing 737 fleet, PHX-based pilots don't have to worry about competing fleet types or equipment bids — training and qualification are simplified compared to a mixed-fleet legacy carrier.

That said, PHX has historically been considered a more junior base within Southwest's system, meaning new-hire pilots may have limited say in landing there right away, and the desert heat is a real quality-of-life factor worth weighing.

Frontier Airlines

Frontier's Phoenix base is the newest of the bunch. The ultra-low-cost carrier celebrated the opening of its PHX crew base in November 2022, initially bringing on up to 180 pilots (plus 275 flight attendants) in the base's first year — a move the airline said would add more than $118 million in annual wages to the local economy. The base opening coincided with a wave of new nonstop routes out of PHX, and Frontier has continued expanding its footprint at the airport since, making it one of the airport's larger carriers by destination count.

Envoy Air: The Regional Option

If you're building time toward a legacy career, it's worth knowing that Envoy Air — American's wholly-owned regional subsidiary — opened a crew and line maintenance base at PHX in September 2022 to support American Eagle's growing Embraer 175 flying out of Sky Harbor. It was Envoy's first West Coast-facing base, joining existing domiciles in Dallas/Fort Worth, Chicago, and Miami, and it gives pilots living in Arizona, California, and other western states a regional on-ramp to American without having to commute across the country. Envoy pilots typically flow to American after several years of service, making PHX a legitimate starting point for a mainline career without ever leaving the Valley.

Worth noting: Mesa Airlines, another regional carrier, is headquartered in Phoenix and still runs its corporate offices and pilot training center there. However, Mesa's actual line flying out of PHX has wound down since it lost its American Eagle contract in 2023 — pilots now interview and train in Phoenix but are domiciled in Houston, Washington-Dulles, or Louisville.

SkyWest Airlines: The Longest-Running Regional Base at PHX

SkyWest is easy to overlook because it doesn't fly under its own name, but it's the largest regional airline in the country, operating nearly 500 aircraft under codeshare agreements with American, Delta, United, and Alaska. Phoenix has been part of SkyWest's network since its earliest days as a hub city, and it remains one of the carrier's 20 active crew domiciles today, flying a mix of CRJ and Embraer E175 regional jets.

For pilots, a PHX base at SkyWest can mean flying for more than one mainline partner depending on which routes are assigned there, and SkyWest sweetens the deal with guaranteed interview programs at Delta and Alaska, plus a pathway into United's Aviate program — giving Phoenix-based pilots a genuinely flexible set of options for where their regional time eventually leads. It's also worth knowing that SkyWest has never furloughed a pilot in more than 50 years of operation, which is a notable point of stability for anyone weighing a regional base against the more cyclical hiring patterns at some of the smaller ULCCs.

Airlines That Serve Phoenix But Don't Base Pilots There

PHX is served by more than 20 airlines, but most fly in and out without maintaining a local crew base. That includes several carriers worth knowing if you're comparing options beyond

Phoenix specifically:

Delta Air Lines operates a sizable schedule from PHX but domiciles its pilots elsewhere — see www.pilotfuture.com/airlines/delta

Alaska Airlines flies regularly from PHX but bases crews at its West Coast hubs; details are on www.pilotfuture.com/airlines/alaska-airlines

JetBlue Airways has grown its PHX presence in recent years without opening a local base — check www.pilotfuture.com/airlines/jetblue-airways

Allegiant Air serves PHX and neighboring Mesa Gateway (IWA) but bases pilots out of its own network of leisure-market cities — see www.pilotfuture.com/airlines/allegiant-air

Breeze Airways and Avelo Airlines, two newer ULCCs, both fly to PHX-area airports as their networks expand; you can track their base growth at www.pilotfuture.com/airlines/breeze-airways and www.pilotfuture.com/airlines/avelo-airlines

None of these currently list Phoenix as a pilot domicile, but airline networks shift quickly, especially among the ULCCs, so it's worth revisiting periodically if PHX is a must for your career plans.

Why Phoenix Appeals to Pilots

A few things make Phoenix a genuinely attractive base city beyond just having options:

Cost of living — Phoenix runs well below many other base cities, especially compared to Los Angeles, Oakland, or New York, which matters a lot for junior pilots on reserve pay.

Weather reliability — minimal winter weather delays and consistent VFR conditions year-round, which cuts down on cancellations and irregular ops.

Training infrastructure — Phoenix is also a major flight training hub. United's Aviate Academy runs its flagship 340,000-square-foot campus at Phoenix Goodyear Airport, CAE operates its Phoenix Aviation Academy in Mesa running cadet programs for American, JetBlue, Southwest, and others, and ATP Flight School has a large training center at Phoenix-Mesa Gateway. That means a steady pipeline of new pilots already living in the area when they get hired.

Commuting access — with American, Southwest, and Frontier all operating significant PHX schedules, plus dozens of other carriers passing through, commuting into or out of Phoenix is easier than it is for a lot of base cities.

FAQ

Is Phoenix a good base for new-hire pilots? It depends on the airline. At American and Southwest, PHX is a long-established base that can be relatively senior, meaning new hires may not always be able to hold it right away. At Frontier and Envoy, the bases are newer and have grown quickly, which has historically meant more junior openings.

Does United Airlines base pilots in Phoenix? United serves PHX with regular flights and trains pilots nearby at its Aviate Academy in Goodyear, but it does not currently list Phoenix as a mainline pilot domicile.

What aircraft do Phoenix-based pilots fly? American's PHX base has historically flown Airbus A319/A320/A321 family aircraft. Southwest flies its standard all-Boeing 737 fleet. Frontier's PHX base operates Airbus A320-family aircraft as well.

Is Mesa Airlines still hiring pilots based in Phoenix? Mesa is headquartered in Phoenix and still trains and interviews pilots there, but current line flying is based out of Houston, Washington-Dulles, and Louisville rather than PHX.

Does SkyWest Airlines base pilots in Phoenix? Yes. PHX is one of SkyWest's 20 active crew domiciles, and it's one of the carrier's longest-running bases, dating back to its early hub network. SkyWest pilots there fly CRJ and E175 aircraft under codeshare agreements with American, Delta, United, or Alaska depending on assignment.
