I was in Australia a few weeks ago and got to visit Perth/Fremantle again--I love the area. I also read about QF and AA each adding a daily B777 flight to Australia: the two flights add just 9% more capacity between the two countries. It got me thinking, why wouldn't UA consider LAX or SFO to PER? Now may not be the best time for the city pairs as the economy softens. It's about 2,000 further and close to the range of a B777: is LAX/SYD to SYD/MEL about the optimal range for a B777?
