Ok, I have some more info. FYI I'd be doing this with Aeroplan miles, as they won't treat my round the world trip as round the world when it comes to point charges. (175,000 points I think)
So far looks like LH419 (747-8) from IAD to FRA, first leg stay a few days
TG921 - FRA to BKK (A380), second leg stay a few days
TG413 - BKK to SIN (A340-600), 3rd leg stay a few days
TG404 & TG606 - SIN to BKK to HKG (777-300 & 747-400 (old first though)), 4th leg stay a few days
Ok, this is where it gets dicey. Would like to try OZ or NH here. Need to get back from HKG to IAD or such. I can do JFK (yuck) so I can experience suites with Asiana.
Thoughts/Suggestions?
