Why Southwest Airlines Stands Out at Ontario Airport (ONT)

Southwest Airlines has carved out a niche of low‑cost, friendly, and hassle‑free travel across the United States. At Ontario International Airport (ONT), the airline offers a consistently reliable service, connecting the Greater Los Angeles Area, San Diego, and the Inland Empire to numerous domestic hubs. Whether you’re a commuter, a weekend traveler, or a business traveler, this article explores why Southwest is a top choice and how to make the most of your experience at ONT.

1. Getting to Know ONT

  • Location: Roughly 50 miles southeast of downtown Los Angeles, ONT serves the Inland Southern California region
  • Terminal Layout: Two primary terminals (A‑E) with a dedicated Southwest ticketing area
  • Passenger Volume: ~25 million passengers per year (pre‑COVID), with high utilization of the Southwest concourses

2. Southwest’s Route Network from ONT
