While the LA/Ontario International Airport (ONT) can be a good alternative when flying into the Los Angeles area, it is still not a major airport – but there are still three airport parking lots available where you can book a spot ahead of time.
LA/Ontario International Airport is located roughly 40 miles to the east of Los Angeles, and can be a less busy airport to fly in and out of than the perenially busy (and confusing) Los Angeles International Airport. Depending on where you live or where your ultimate destination is, using the LA/Ontario airport can be a really good choice. It is a much smaller airport than LAX, so there are not many choices for places to eat or shop while you wait for a flight. For traffic information, see the Compass website.
