re: 4-5 continents in 2-3 weeks

I did 4 continents in about 4 weeks last summer. Atlanta-based but had trips to London, Buenos Aires, New Delhi and Singapore in that time. All in business class which makes it much easier. I like going west better than east, and it’s easier for me to adjust to Asia than Europe. The short flight time overnight to Europe doesn’t allow for a good sleep inflight whereas 24hrs across 2 flights allows good sleep time.

Melatonin at bedtime every night in the new time zone helps. Don’t think about what time it was where you were or jet lag - the time is the local time Always!!

Get sleep when/where you can and roll with whatever comes up.
