If you’re in Belgium and need car rental Brussels airport has many options. However, getting the best car rental rate isn’t always easy, and comparing rates, and booking before you arrive in Brussels can often save you money. It may pay to look at renting from a location other than the airport, and of course renting a smaller vehicle will keep that rate lower. Always ask about applicable discounts, such as corporate, AARP or those discounts that are offered by any affiliated credit card. One way car rental companies make money is to upsell and offer you features you don’t need, such as a GPS navigation system. And your credit card may also provide insurance on car rentals, meaning it’s not necessary to pay extra at the rental counter. Belgium’s roads are waiting for you once you have your rental car and have secured the best rate.
