I'm really new to this but I've been trying to make the most of this forum, which is a great resource. So far I've come up with the following itinerary.

AUG07: YYZ-LHR
FEB08-MAY08: LHR-TLV-MAD-HEL-DXB-HKG-NRT-BKK-BOM-SYD-AYQ-MEL-AKL-LAX-SFO*-SEA*-MIA-YUL
* = stopover

19 segments total. I hope to add one more if JAL becomes a member before I book.

I have a couple questions:
1) Is this a valid, reasonable, itinerary?
1) As I understand it, the locations are locked but the dates are flexibile (except for the first IC flight). What happens if the available routing changes during my travels?
2) Why does the ONE RTW planner show no flights at all for LAX-SFO?
3) Regarding the transcontinental exception, is it possible to fly from Dubai to Perth (DXB-HKG-PER) and then go back into Asia?


Thanks a bunch
