Oh, but don't forget to add "heavy" to your call sign when taxiing or cruising at FL370...
Actually, most SWA crews use pretty good ICAO phraseology when they fly to the Caribbean. It's just a domestic thing, I guess.
I wouldn't go as far as calling it a huge potential for a serious accident. There is never just one factor leading to an incident/accident.
