Buying in Gib: you have to use a TA and there is just one (I think it is called Bland, see http://www.gibyellow.gi/company_resu...Service_ID=461 or the FT trip reports and it should be described in one of them). Or Google. I'm not sure but I have it in my mind that GIB is served from LGH not LHR, which might be a problem.

As for F quality, you have 3 high-quality segments (yvr-jfk, jfk-hkg and hkg-lon). Some routes have seasonal A (JFK-EZE) which is moderate quality. I thought LAN has removed F seats from their 763s, so there wont be on SCL-GYE-JFK. Personally I would change the Asia segments to be HKG-NRT-HKG-DPS-HKG and leave SIN and BKK for future trips from Oz (very cheap fares from there and you'll see more of each than you want if you do much travel to Europe).

IPC is a great use of OWE as it is otherwise quite expensive to get to as well as difficult. Maybe the most isolated spot on earth. When I went there were only 2 or 3 flights per week (I think it is daily now, and 2 flights on some days)....scheduling was tough when there were so few flights, and you probably wont be able to get A (but still worth going!).
