I was surprised that all faster trips go east.

Must have to do with easier direct routes.

 

 

Tail winds going east. 

 

It's actually shorter to go that way also.  The long flights from Asia to New York go far north over Alaska and northern Canada which is shorter than if you go the other way and route through the middle east closer to the equator.

Well if you fly that way to New York you're going to get the worst jet laggy ever can get. Definitely don't go over the Pacific when flying to New York.

why?

Cathay has the fastest connection (total 19:25 hours) but you have to endure an ultra long haul (15:35 hours, A350).

Starts in the morning 11:50 AM, arrive 7:05 PM.

I like the idea of departing at a civilized time of the morning where Ive had a good nights sleep prior. Then arrive in the States at night time and get to sleep at 11pm in the 5 star hotel. Jetlag is less the next day perhaps?

For ultra long-haul, non-stop, especially from and to NE Asia but the actual routing on the day still depends on the (forecast) winds.

Singaore Air has a direct flight from SIN to either EWR or JFK.    It’s 17 to 19 hours of flying time.

Regards jet lag when I was in the military, the saying was, "west is best, east is a beast", and I've found that to be fairly accurate.

I never heard that saying when I was on active duty back in the early 1970's.  But based on my travel since then, I agree ...

Which ever airline that can get you there in the shortest amount time on a 787-9. 787 has a cabin altitude of 6000ft. This means higher partial pressures of oxygen (and also moisture levels) in the 787, which decreases many of the symptoms often attribute to jet lag, better sleep as well. Slightly more roomier and comfortable. 

That's a tough requirement.

Browsed through the 30 fastest connections and only AirCanada via Vancouver does 787 on both legs (can't see whether  "-9").

 

Starts with long leg:

 

8:35 AM to 6:55 AM (13h 20m)

 

8:40 AM to 4:51 PM (5h 11m)

 

Others do 787 only on short leg within Asia.

I would definitely recommend not to transit in Canada.  All transit passengers on international flights arriving in Canada need to go through Canada immigration and customs.  If the OP's family is Thai, they may even need a transit visa for Canada.  Much better to choose one of the many airlines with easy transit airports.
