This terminal is designed to handle a higher volume of passengers and offers a range of amenities, including dining, shopping, and lounges. Understanding the terminal layout is crucial for a smooth travel experience, especially when flying with Southwest.
To effectively navigate Terminal 4, start by familiarizing yourself with the ONT Airport terminal map, which is available online and at various points throughout the airport.

Additionally, the map indicates the locations of restrooms, charging stations, and food options, ensuring you can plan your time efficiently while waiting for your flight.
One practical tip for Southwest passengers is to arrive at least 90 minutes before a domestic flight and 2 hours before an international flight, as Terminal 4 can experience moderate crowds during peak travel times.
