We are travelling from Chicago to Kuala Lumpur (and then the next day to Borneo). We are travelling in business class. I have option of flying via New York-Hong Kong-Kuala Lumpur (leaving NYC at 10:00 AM, which also means leaving Chicago night before to fly to New York where we would spend the night in hotel,and arriving KL at 6:40 PM) or travelling via LA at midnight, i.e. 2 AM Chicago time, and arriving in Kuala Lumpur at 12:30 PM.

My question is which option might be easier on the body and for jet lag. Does it matter? I am eager to enjoy business class and wonder whether it might be more fun starting the long leg at 10 AM versus Midnight).

Any thoughts and experiences?

Thanks,

Daniel
