* Enterprise: Often has competitive rates, particularly if you book in advance. They have a large presence across the US.
* Avis: Similar to Enterprise, Avis is a major player and frequently participates in price wars, leading to good deals.
* Budget: The name says it all – they aim for budget-conscious travelers.
* Alamo: Often bundled with Enterprise, Alamo is another reliable option for finding affordable rentals.
* Hertz: While not always the cheapest, Hertz sometimes has competitive pricing, especially with promotions.
To find the absolute cheapest option:
* Compare prices on multiple websites: Don't rely on just one booking site. Use aggregators like Kayak, Expedia, Priceline, Google Flights (yes, they also do cars), etc., to compare prices across all the major rental companies.
* Be flexible with your dates: Rental car prices can vary significantly depending on the day of the week and time of year. Experiment with slightly different pickup and return dates to see if you can find a better deal.
* Consider off-airport rentals: Rental locations at airports often charge higher prices due to fees and convenience charges. See if picking up your car at a location slightly further away saves you money. You'll need to factor in transportation costs to the rental location, though.
* Look for discounts: Check for AAA, AARP, military, or other membership discounts that might apply.
Important Note: Always carefully read the terms and conditions, especially regarding insurance coverage. While a lower base rental price might seem appealing, hidden fees and inadequate insurance can quickly negate those savings. Consider the total cost, including insurance, before making a decision.
