1. Try an Aggregator.
If you prefer not to use an opaque site, don’t bounce around from one company website to another; go to an aggregator site like Kayak or SideStep instead. Once you’re ready to book, these sites link you directly to the rental agency’s own website. Earlier this year, Kayak added a new option that allows travelers to search for hybrid vehicles.
2. Avoid Renting at the Airport (If You Can).
Airport locations are often required by law to add local and state surcharges. Neil Abrams, an industry consultant, estimates that airport fees can hike the cost of renting a car by 25 to 45 percent. To make sure you don’t pay more than you have to, Perkins advises reserving from a city center or suburban location. “Most airports try to capture fees from any rental office, even those running shuttles from airport terminals to nearby offices that are not directly on the premises,” he says.
