Not only airports have PNR… heliports also. Why? We guess for someone to unlock the main gate. If you intend to land be advised to have 50€ cash. The requirement for POS does not apply here…
The same like Antiparos island, whose heliport is very busy during summer season. The municipality which is responsible for the operation of the heliport and of course getting the 50€ fee. At the initiative of the heliport personel you will have always a cold bottle of water for your passengers although the municipality says they don’t have a budget for that… the funds for water or some basic maintenance come from the personel itself…
