I've heard this quite a few times today from controllers:
Cactus...correction, American xxx
I guess it'll take a little bit to get used to saying American instead of Cactus...
You'd actually think otherwise for this.
the previous confusion was that during the AWE/USA merger, both AWE and USA were still using both Cactus and US Air callsigns with their flights, and didn't standardize on a single ICAO code for the airline after the SOC was obtained.
In this case, AAL was always separate, just as AWE was always separate. Unless they make the same mistake that AWE/USA did, they should all be filing under the AAL ICAO code..
