Would Qantas have the commercial clout over Singapore with out the need for the Australian Govt to act as it's negoiator. Qantas is the biggest user of Changi outside of SQ themselves. What would be the ramifications for Changi if QF upped and went to say Sepang which has been trying to lure the white rat for a number of years? I really wonder what the commercial advantage of hubbing at Changi is? The Singaporean population that totals to the about the same as Sydney would not be a crucial market for any airline especially with the number of carriers operating out of Changi so why the attraction? Sepang is new modern and provides all that changi does when it comes to transit.
