I'm looking for suggestions to Vietnam next year and came up with some decent options using miles. The LH 380 was a big disappointment so discounting the excitement for that, anybody have any experience based advice on the following:

NYC.. routing to Europe on CO/LH then HAN via TG
NYC-TYO-HAN routing via ANA
NYC-ICN-HAN routing via OZ
I purposely left out UA but am open if you can convince me....
This would be in business or first depending on availability.
Again, I'm searching for routing, metal and comfort along the way. Once I make my decision based on your suggestions I'll do my search and destroy for award availability.
Thanks!
