While the existing Pending Create process allows only registration requests for .aero domain names, registrars have the option to request for more than one ENS Class to be associated with their ENS object. Registrars may request one or more of the following classes   default (aero), airport and/or airline   to be associated with their ENS object. Following SITA's approval, registrants will be able to use the same ENS object to request allocation of reserved names via the web interface on www.information.aero. Please note that only one Membership ID is issued per Pending Create transaction.
