Finding and Accessing Southwest Airlines Terminal 4
Navigating to Terminal 4 is straightforward, thanks to ONT’s compact layout compared to larger airports like LAX. The terminal is located on the east side of the airport, accessible via major highways including I-10 and I-15—ideal for those driving from Los Angeles, Riverside, or San Bernardino counties.
By Car: From Los Angeles, take I-10 East for about 45 miles. Parking options abound, with Terminal 4 featuring a convenient garage just steps from the entrance. Economy lots are available for longer stays, with shuttle services running every 10-15 minutes.
By Public Transit: The Omnitrans bus system connects ONT to regional areas. Line 61 from downtown Ontario or Line 81 from Rancho Cucamonga drops you right at the terminal. For rideshares like Uber or Lyft, designated pick-up zones are clearly marked outside baggage claim.
- By Taxi or Shuttle: Taxis are readily available curbside, and services like SuperShuttle offer pre-booked rides from nearby hotels.
Insight: Arrive at least 90 minutes early for domestic flights to account for traffic, which can peak during rush hours (7-9 AM and 4-7 PM). Families with children should budget extra time for security.
Check-In, Security, and Boarding Process
Southwest’s check-in at Terminal 4 is user-friendly, with dedicated counters on the lower level for bag drop and ticket printing. If you’re checked in online via the Southwest app (recommended 24 hours before departure), you can skip the lines and head straight to bag drop.
Security Tips for a Hassle-Free Experience
- Use TSA PreCheck if eligible—Southwest partners with CLEAR for expedited lanes in Terminal 4, cutting wait times significantly.
- Security lines average 15-20 minutes, but can spike during holidays. Pack liquids in a quart-sized bag and keep electronics accessible.
- Southwest’s open seating policy means boarding position is key: Check in exactly at the 24-hour mark to snag an A-group spot.
Example: On a recent trip from ONT to Las Vegas, a traveler using the app for mobile boarding passes breezed through in under 10 minutes, allowing time for a quick coffee before boarding.
Baggage claim for arrivals is also in Terminal 4, with Southwest’s carousels clearly labeled. Lost bags? Head to the Southwest baggage office near carousel 4 for quick resolution—their two-free-bags policy minimizes lost luggage issues.
