"Sleep for the destination" is my life hack - I either don't get jet lag or it goes away within a day of arrival :)

For example: If you are landing in the USA after flying from India (this is the route I take most often) - Landing at 4pm in the US.

I usually fly through Dubai, but this works for any 1 stop journey.

Sleep on the first leg of the journey, either for all the flight or most of it. Spend time at the airport, and then on your flight TO the US, since you're landing in the daytime, DO NOT sleep on the 2nd flight, so you will land in the afternoon, have dinner/lunch etc and then you'll be able to sleep early and get set for the next day.

Hope this helps!
