I rent a car at National at the Birmingham airport once or twice a month. I am Emerald Isle Executive. Birmingham does not have an Emerald Isle or an Executive Emerald Isle but that has never been an issue. I just go to their booth out in the lot and they give me a lots of cars to choose from. They give me the keys and I go. There is never a line and they are very fast and efficient. They always have a great selection and I always get a very nice car to drive. Returning the car is just as easy. They are always very fast and again there is seldom a line. I have had consistently fast courteous service. The rental lots are just outside the front of the airport so that is great too. This is one of my favorite National locations.
