i have never understood why the FAA has not adopted the EU system of callsign modification, e.g. SWA1328 could have used the callsign SWA132H and SWA3828 could have used the callsign SWA382J. Risk reduced. I loved the callsign mod when I flew contract in Europe.
Good point, and while we're at it, why doesn't the FAA try to stamp out the use of slang?
"Southwest thirteen twenty-eight" and "...checking in three five oh" and "runway four" might sound cool on the radio, but it's not ICAO standard and has huge potential for a serious accident.
Oh, but don't forget to add "heavy" to your call sign when taxiing or cruising at FL370...
