I am a traveler and recently at the Southwest Airlines ONT Terminal check-in process was quick and simple. With lots of seating and charging outlets, the terminal is tidy, roomy, and simple to use. Security was swift, and there were food options for a quick drink or snack. All things considered, Southwest at ONT provides a comfortable, easy, and stress-free flying experience, making it an excellent option. visit us : https://www.exploreterminalsinfo.com/southwest-airlines/southwest-airlines-ontario-airport-terminal-ont/
