I know that the airlines' airfare system is very complex and changes all the time, but I found something interesting while surfing the 'net(nothing better to do in Iraq!) I was looking at United roundtrips in First Class around, for example, September 2009(sep 20-sep 30 to be exact). The LAX-SYD-LAX trip was over $24,000. But when I looked at a LHR-SYD-LHR with stops in LAX each way, the total came out to $17,000.
My question is why would the LHR-SYD trip be $7,000 less?
and wouldnt the airline just book the ticket as 4 one-way flights in first class?
Thanks in advance
