Many of the above frequencies were previously analog, and have switched to DMR. The Hertz frequency may actually be for Dollar/Thrifty, since Hertz already has a separate frequency at the airport.

The Aeronautical Radio trunked system was found to have at least one unencrypted group; other groups are using Enhanced Privacy.

The United Airlines trunked system remains Motorola Type II; it was suspected that the system may have been converted to Capacity Plus or Connect Plus, as United seems to be doing with some of their systems at hub airports (such as Chicago) in the United States.
