Budget is Ontario Airport’s cheapest supplier for an Intermediate car over the last 12 months, averaging $54 a day from 1,868 prices, but you need a credit card and its desk averages 33 minutes. Budget does not yet have enough reviews for a score, so you cannot assess it by a review rating. For an Intermediate car over the same 12 months, Alamo averages $69 a day from 4,233 prices, $15 more a day than Budget, and scores 97/100 from 1,439 reviews in the last 5 months. Consider Alamo if pickup time matters to you: its desk averages 10 minutes.

The cheapest company can cost you a longer queue or a bigger deposit, so check the review score and desk wait beside each car in the results before you book.
