Accusations of bad RT technique cannot be directed at one airline. There are many pilots out there(and as many controllers I am ashamed to say) who have forgotten that the whole point of good/standard RT is safety. I have experienced the cream of the worlds favourite airline not even bothering to call on final, then when you ask if they are on frequency the reply has been . . . . "YUP".
Equally I have heard some of the stuff my colleagues have come out with and as much as you can try to joke about how sloppy they are they will not take any notice because they think they know best. So, all you RT users out there . . . . STOP BEING NAUGHTY
