Cheap Budget Car Hire Deals at Phoenix Sky Harbor Airport, PHX

Research fuel prices in the area where you'll return the vehicle. Filling up at a local station may be cheaper than paying for fuel through the rental company, especially if they charge higher rates.

Ask if there are extra charges for picking up at the airport versus off-site locations.

Check the operating hours of your rental company, as some may have limited hours at airports.

Before renting a car, check if your personal car insurance covers rental losses. Many personal auto insurance policies and credit cards offer coverage for rentals, which could save you from extra insurance fees.

Some rental agreements come with mileage limits, while others offer unlimited mileage. Make sure to review the mileage policy to avoid unexpected fees.

Many companies offer apps with live updates and alerts regarding your vehicle pickup.

Many rental companies require payment by credit card and may not accept debit cards. If you only have a debit card, check the rental company's payment policies in advance and look for suitable options.

To save on refueling costs when departing from Airport, look for deals with a 'full to full' tank fuel policy, or even better, a free tank fuel policy, as opposed to a 'half-full to full' one.
