Thanks for that advice! I'm planning a trip to Vietnam in Feb. I'll be flying out of Atlanta & want to fly into HCMC. Spend 3-4 days there & then fly to Da Nang, stay there a few days with side trips to Hoi An & Hue. Then fly to Hanoi for another couple days, flying back to Atlanta from Hanoi.Because of the really long flight from Atlanta to HCMC, I want to fly business class. I've been looking at Korean Air. Their prices are higher than going with Qatar or Turkish, but also are far less time. Do you think fares would be lower if I waited to closer to end of Feb and into early March? Any other travel advice you could give would be appreciated as this will be my 1st trip to Asia & I'll be traveling alone.
