Sobelena,
I think at any age, it's a bit much. The longest flight I've done is Los Angeles to Bangkok. I don't remember the exact time, but it was around 17 hours.
I remember it was longer than usual because we had to deviate around two big lows in the Bering Sea. We flew north out of Los Angeles, crossed into Canada and eventually coasted-out over the Yukon into the Beaufort Sea! Made landfall over Siberia, flew over the Sea of Ohkotsk, into China, with the obligatory rerouting in the Bejing area and then down to the Land of Smiles. How to cross the Pacific without flying over it!
I don't need a stopover, but I do find a change of plane is nice, just to be able to walk around, even if it adds a few hours to the journey.
