About flights from Ontario (ONT)
Ontario International Airport doesn't get nearly enough credit. Sitting about 35 miles east of LAX in the Inland Empire, ONT punches well above its weight for a regional airport — 31 direct routes, 4 countries, and zero of the chaos you'd deal with at Los Angeles. I've routed through here specifically to avoid LAX's nightmare terminals, and honestly? It's one of the smartest moves a Southern California traveler can make. Shorter security lines, easier parking, and you're wheels-up faster than most LAX passengers have found their gate. The reach score of 65 out of 99 tells the real story. This isn't just a hop-around domestic airport. ONT connects you to Taiwan, El Salvador, and Mexico — real international travel from a mid-sized regional hub.
