Dec 23, 2011 Alicante Airport Advice
If you are hiring a car from Alicante airport but not arriving by air, and being taken to the airport by a friend for example, then you can drive directly into the car rental area ( follow rental car signs) close to the terminal building, drive through the automated barrier and go to the level where your car hire supplier is located. For example if you are collecting from Europcar, Sixt or Centauro then drive to the 3rd Floor and report to their office located at this level.
You will not need to enter the actual departures or arrivals area. Ask your car supplier for a ticket so your friend can exit the building without charge !
