Cheap Sixt Car Hire Deals at Baltimore Washington International Airport, BWI

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.

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.

Before leaving the rental location, inspect the car for any existing damage and ensure it’s documented. Take photos if necessary to avoid disputes when returning the vehicle.

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.

If sharing driving responsibilities, check the policies regarding additional drivers. Some companies charge fees for each extra driver, while others may include it for free under certain conditions.

When selecting insurance, consider whether it includes free excess coverage. Free excess means you won’t pay a deductible in case of damage, providing additional peace of mind. Compare options to find the best fit for your needs.

Allow for possible delays at the rental desk, particularly during busy travel times.

Before returning the vehicle, clarify the return procedures with the rental company. Knowing where to drop off the car and any required inspections can streamline the process.
