Notwithstanding the provisions of Alaska Stat. § 02.15.090(a), the department may not exclude from the streets, roads, highways, parking facilities, or other portions of a state-operated airport designated for operation or parking of ground transportation vehicles, nor may the department prohibit from picking up and discharging passengers those motor vehicles commonly known as “courtesy cars,” which are owned or operated by hotels, motels, or other similar places of public accommodation for the transportation of their guests to and from the airport at the request of the guest and for which service no charge is made to the guest, and “airport parking shuttles,” which provide transportation services between the airport and off-airport rental car offices and remote vehicle parking locations.
