Kahului (OGG) After exiting your plane in Maui you will enter the passenger terminal (mostly open-air) of the Kahului airport. Claim your baggage and proceed to the car rental company booths located out the main entrance and to your right.
Since you already have your discount reservation, follow the sidewalk around back to find the Maui car rental shuttles. Locate the sign with your specific rental car company on it.
The shuttle literally runs every 3-5 minutes, so you never need to wait more than a few minutes.
If the booths are closed (many of them often are) when you arrive, you can simply go around the back of the booths and hop on your company's shuttle. You will complete your paperwork after exiting the shuttle at the car rental lot. The majority of the lots are all within a 3-4 block range of the OGG airport. Map and Directions
Kapalua (JHM) This airport can be a nice place to arrive and depart if you are staying in one of the many condos on the North Shore. Operations are currently limited to daytime hours. All of our car rental partners are located in the small town of Lahaina. They operate on a limited schedule (7 AM to 5 PM) seven days a week. Of course, taxis are available 24 hrs per day.
Your confirmation email will have a phone number in it. Once on the ground at JHM, call the agency for their complimentary shuttle service. It typically takes only 10-15 minutes for the shuttle to arrive. Map and Directions
