    I don’t think Operating certificate has anything to do with an airline’s callsign. At least according to the the wiki when America West and US Airways merged the US Airways certificate survived, but the callsign that survived was as you said “Cactus” and the ICAO code was “AME.”

    Here’s the link to the wiki:

    Interesting. Assuming Ch 9 stays, it’ll be weird to be listening for Continental instead of United! If Ch 9 goes away, moot (or mute or moo) point.
