Apacau, REX aren't hanging out for Singapore Airlines. I can tell you very confidently that aint the case as Singapore will not be starting here in Australia.
Singapore have never been interested in starting here. I have it on very good advice that the press rumblings about SQ flying here in Australia are merely grumblings started by vested interests to get SQ to declare their hand early either way.
The federal government for all their crowing in the press of open skies etc will make it very hard for a third entrant, particularly SQ. AND even more so because Geoff Dixon and co have a direct whinge line to John Howard. Don't beleive me? well make some informed calls to Parliament House( Anderson's office, Dept of Prime Minister and Cabinet even) and you will find out just how cushy the board of QF are with the Howard government.
