As far as North America goes, mainly to meet up with friends, and then to earn points/credits.
I need to be in BWI for 29JUL-01AUG and MCO for 05-08AUG.

This is what I currently have in the planner:

01 CMB-SIN: CX710 17JUL
02 SIN-NRT: JL710 17JUL
03 NRT-HKG: JL731 25JUL
04 HKG-JFK: CX830 27JUL
05 JFK-BWI: AA3944 27JUL
06 BWI-ORD: AA4296 01AUG
07 ORD-MCO: AA1872 04AUG
08 MCO-DFW: AA1589 08AUG
09 DFW-SEA: AA2033 08AUG
10 SEA-DFW: AA1230 08AUG
11 DFW-CDG: AA48 09AUG
12 CDG-HEL: AY876 12AUG
13 HEL-FCO: AY781 15AUG
14 FCO-HKG: CX292 15AUG
15 HKG-CMB: CX711 16AUG

I might replace JFK-BWI with Amtrak or a cheap flight.
Currently looking at something like this for postioning flights:
MEL-PER: QF775 16JUL
PER-SIN: QF77 16JUL
SIN-CMB: CX711 16JUL (turn around onto DONE3 sector 1)

CMB-SIN: CX710 17AUG (turn around from DONE3 sector 15)
SIN-MEL: QF10 17AUG
MEL-CBR: QF850 23AUG
Haven't been able to get any pricing online for this though.
