Hi guys/girls

I've got (yet) more questions - sorry if they're a bit dumb .

Basically I'm looking to go on a round the world trip in December (this year), and have had a quick whiz on the Oneworld RTW Planner. I will be booking the five of us in Business for the whole trip.

I'm limited to 3 weeks to do this trip in, so have got (so far)

EDI-LHR (BA) Depart 17th Dec
LHR-HKG (BA) Depart 17th Dec
HKG-SIN (CX) Depart 21st Dec
SIN-SYD (QF-A380) Depart 24th Dec
SYD-JFK (QF) Depart 29th Dec
JFK-LHR (BA) Depart 3rd Dec
LHR-EDI (BA) Depart 4th Dec

I know it all seems rushed, but I had to do that so I could get flights back from JFK and LHR - BA isn't letting me book past the 4th January 2010.

I also want to get a rough price. So far, I've got quoted on the site £5,141.10. The price sounds reasonable to me as on BA.com I'm getting quoted £3,974 per person one way in J (LHR-HKG).

Anyway, my questions are;

1. Do you people have any places that you think are missing and that would recommend? Should I spend more time in a certain place, and less in another?

2. All of the fights are booking into D class. I assume I will be able to get TP's off these flights, and also off the CX and QF flights?

3. What are the limitations of D class tickets? Non-refundable? Non-changable?

4. Is there any way that I can find out how many TP's I'll get for the whole trip?

Thanks in advance
Marc
