This occurs when someone conducts a search for a domain name and, shortly thereafter, someone else (a "front runner"), using information obtained during the search, pre-emptively registers the name. This action prevents domain names from being registered by those who were originally interested.
Suggestions have been made that front runners buy search data from Internet service providers and/or registries in order to find names being searched. We are pleased to confirm that the .aero registry has NEVER sold and will not sell search data to any party. We absolutely oppose the practice of front running.
Anyone suspecting an instance of front running on .aero names should contact .aero technical support at techsupport@registry.aero or you can call +1.416.619.3031.
