Phoenix vs. Tucson: There’s a $68 Airfare Gap Between Them

Arizona's two airports in the national top 100 tell different stories about domestic airfare. Only In Your State analyzed recently released data from the Bureau of Transportation Statistics, and the numbers show a meaningful split between the state's two major hubs—one that's worth understanding before you book.

Phoenix Sky Harbor International Airport (PHX) averaged $370.91 per domestic ticket in 2025, ranking 35th most affordable nationally out of 100 airports. That's $16.09 below the national average of $387—a modest but real advantage for Phoenix-area travelers.

Tucson International Airport (TUS) tells a different story. The average fare from TUS was $438.77 in 2025, ranking it 88th out of 100 for affordability—well above the national average and $67.86 higher than Phoenix.

Why Phoenix Outperforms Tucson

The gap largely comes down to scale and competition. Phoenix Sky Harbor is the 11th busiest airport in the country by passenger volume, which attracts a wide range of carriers and creates the competitive pricing environment that benefits travelers. More airlines fighting for the same passengers tends to push fares down.

In addition to lower base fares, Phoenix Sky Harbor's larger carrier presence often translates to more direct route options. For Tucson travelers, factoring in long-term parking fees and gas for the I-10 drive helps ensure the overall savings still come out ahead.

Tucson International, ranked 75th nationally for passenger traffic, operates in a smaller market with fewer carrier options. That dynamic means Tucson travelers pay a premium for the convenience of a local departure—$67.86 more per ticket on average.

For Tucson residents willing to make the roughly 100-mile drive to Phoenix, the math could make sense depending on the trip. At $67.86 per ticket, a family of four would save roughly $271 per trip in airfare—potentially enough to cover the drive and then some.

The Full Arizona Picture

Phoenix's rank of 35th nationally is genuinely good news for the greater Phoenix metro. With fares below the national average and a passenger volume that rivals major hubs, PHX offers a solid foundation for affordable domestic travel.

This data reflects 2025 averages from the Department of Transportation, released in May 2026. It predates a recent uptick in prices driven by rising jet fuel costs, so current fares may be higher. The relative gap between Phoenix and Tucson, however, tends to hold over time.
