Ok. As it seems that I shouldn't sacrifice any minute in Thailand for a -already short- stop in a city Ill most likely get a chance to visit later on in life, I made some changes to get me to Thailand faster.
Hold #1
JFK-HKG-BKK leaving JFK at 2:50pm landing in HKG at 6:50pm and then continuing to BKK at 9:20pm landing in BKK at 11:10pm currently all in J.
Itll be a long day and a half of travel and Ill take a hotel for the night in BKK and then move to CNX the next morning via a cheap revenue ticket.
Hold #2
JFK-HKG-CNX leaving JFK at 10am landing in HKG at 2pm and then continuing to CNX at 3:25pm landing in CNX at 5:20pm currently with one seat in J and one in F and the HKG-CNX leg on Dragon Air in Economy.
Might be a bit of a tight connection and missing out on a 3hr leg in J but that way I basically gain around ~20 hours in CNX by going straight there.
Disclaimer: Dragon Air doesn't fly that route daily and not always at the same time so I just added the DragonAir flight to the leg on which I'd be able to take them the same day I land in HKG.
