I have never been to Egypt and know nothing at all about the real subject of this thread. I just wanted to say that it's a pleasure to see someone use an airport code to refer to an airport, rather than a "look how cool I am, I know the airport code for this city" in sentences such as "I live in MIA." (I doubt such a poster actually does, though "I live under the usual approach path to MIA" is plausible if unfortunate.)
