Airports in the West

The West region is home to 8 of the 50 busiest commercial airports in the United States, spanning California and Nevada. Combined, these airports move roughly 254.8 million passengers a year.

How airline hubs concentrate in the West

Hub-airline strategy explains a lot about why some airports in the West have grown faster than others. The major hubs in this region are operated by Southwest Airlines, Alaska Airlines, United Airlines, American Airlines, Delta Air Lines, Allegiant Air, Frontier Airlines, and Spirit Airlines, and the airports that host them tend to dominate both passenger volume and nonstop route coverage. Travelers based near a hub airport in the West typically enjoy the deepest schedule — more frequencies on popular city pairs, more nonstop options on niche routes, and easier rebooking when irregular operations strike — but also pay a modest premium on average fares because the hub carrier captures most of the local origin-and-destination market.

By contrast, non-hub airports in the West often offer more competitive low-cost-carrier service from Spirit, Frontier, Allegiant, JetBlue, and Southwest, with cheaper headline fares on point-to-point routes that a hub carrier might not bother with from a non-hub city.

Choosing between airports in the West

Travelers planning a trip into the West often have a meaningful choice between airports. A flight into a smaller secondary airport closer to the final destination can save hours of ground transportation but may cost more or have fewer nonstop options. A flight into the largest hub in the region typically offers the broadest schedule and the cheapest fares but a longer drive on the back end. The per-airport guides below cover terminal layouts, airline service, parking, ground transportation, and amenities so you can compare candidates against your specific itinerary.

Comparison checklist when picking among West airports: total drive time including likely traffic at the time of day you'll arrive, parking cost (which can add $100–$300 to a week-long trip), nonstop versus one-stop fare differential, time-of-day preference for departures and arrivals, and whether checked baggage or a tight connection makes the larger airport's deeper schedule worth the longer drive.
