If you want to reserve a car hire online from National Car Rental, here’s a step-by-step guide for you to follow:

-Choose your home country from the “Where do you live” drop-down box.

-Type “Cardiff Airport (CWLT01)” into the “Pickup Location” box.

-Choose your pickup date in the two “Pickup Date” drop-down boxes.

-Choose your pickup time from the “Pickup Time” drop-down box.

-The National Car Rental website should have autofilled the “Dropoff Location” box with “Cardiff Airport (CWLT01).” If for some reason it didn’t, manually enter it yourself.

-Repeat the steps you followed for your pickup date and time for the “Dropoff Date” and “Dropoff Time” boxes.

-Finally, click the green “Reserve Now” button.

-At the top of the next page that loads, you will see the following message in red:

“Airline and Flight Number are mandatory at this rental station”

-As you look down the page, you will see an “Emerald Club Member” section, as well as an “Optional Rate Information” section. If either section applies to you, fill them in now.

-Otherwise, skip to the “Flight Information” section, where you need to enter your airline and flight number.

-Click the green “Continue” button at the bottom of the page.

As long you entered the correct airline and flight number, National should now display a list of their available car hires for you to evaluate, and decide which one best fits your needs and budget.
