have you ever thought of worrying about more important things than how pilots talk on the radio??? and to answer your question, maybe they say "with you" for the same reason you list yourself as a BOEING capt. Who cares???????????????, not to say you probably have a Boeing Captain bumper sticker on your car, just as a new pilot would have FAA licensed pilot, so dont go bashing on where you once were which probably was not that long ago.
