Or at least in my case it is.
Also winds/jet stream at actual flight level at the time flown, and finally the price of Jet-A(1)/B at the involved FBOs.
Or just use something made by Jeppesen, Universal Weather and Aviation, Air Routing International, ForeFlight, ...
Or use the stuff built into the flight deck of any contemporary Jet not belonging into a museeum :)
Or let the pilots handle that, which come with the Jet, anyways, when you charter one.
Delegate!
