YOUR MISSION SHOULD YOU CHOOSE TO ACCEPT IT.....

OK Here Goes - I'm very new to the site but have picked up quite a bit of interesting information and now I'm planning in a trip in about 7 weeks and would love the advice of all you guru's out there.

I live in PER. I need to visit ATL on 10&11 Jun and AMS on 21&22 Jun.
I also need to go to LON, BWI, ORD, YVR, TYO, SYD. The dates for these are flexible, but need to be close to above and at least one weekday at each. I only want to be away from wife and kids for 2-3 weeks max.

I am a QFF with about 120,000 points but still only bronze status (mostly credit card points). I am obviously keen to maximise points and SC's. I assume I need to avoid AA as much as possible since no points?

I wrote to travel agent in BKK to see about prices and they quoted 121,160THB ($4,045AUD) which really surprised me as the TA here quoted me $3,239AUD - high season and $2939AUD if I leave before 31 May. Have I misread something here as there seemed to be a lot of posts saying BKK was really cheap for OWE?? Is there somewehre else I should look at getting the ticket? And od the season rules apply worldwide?

So .... thoughts on best itinerary, price etc. I'm happy to buy a OW to Asia if it means I can get a cheaper LONE4 fare?

Lots of questions - no anwsers. Thankyou very much in advance if you have any words of wisdom for this confused traveller!!
