I am a traveler and recently at the Southwest Airlines ONT Terminal check-in was quick and simple, and the staff was helpful and kind. The terminal has plenty of seating and is tidy, contemporary, and well-organized. If you need a quick snack or drink before your flight, there are options available. My wait time was short because security lines moved swiftly. All things considered, Southwest is a fantastic option for flying because it provides a relaxing, effective, and stress-free journey at ONT.
