Hi. I am planning an AONE4 trip for the first time. I've read a lot of the posts in this forum which has been a real help, but have a few extra questions. My planned route is something like GIB-LHR-HKG-SIN-SYD-LAX-LHR-GIB.

First, is Gibraltar still one of the cheapest locations to buy? I'm based in London and it doesn't seem too much of a hassle if it works from there.

Can I take the GIB-LHR sector a few months before the LHR-HKG sector? Or do I have to transit straight through LHR?

And do I have to return to GIB at the end of the trip or can I just throw that sector away? Will that have any impact on miles/points accumulated on the rest of the ticket?

The SYD-LAX-LHR sectors are straight through with no break but would seem to involve a 7 hour layover in LAX. QX seems to have one straight through SYD-JFK flight a day (20 hours - can that be right!?). Has anyone ever taken this sector.

Thanks.
