Those arguing for SQ to fly Aus-US claim that it will be a boost for the Oz economy and create new jobs. Sounds good....in theory. So far I have not seen any concrete evidence of this. Exactly how many jobs would be created? Exactly how much of a boost to the economy will there be? Quoting economic textbooks is one thing. Show me some hard evidence that allowing SQ to operate the route will make any difference. If there is this huge unfilled demand for the trans-pacific route, why don't other US airlines think it is worth flying?
