Assuming you are just on a fly trip to Delhi to Mumbai or you are planning your family holiday to Dubai, which would be your choice of a new jet: a light jet or a heavy jet?
The choice is essential. Take the example of a sports car and a subprime car- both of them drive you to the same place, but in a very different manner.
Deciding on what to use, be it a light or heavy jet, implies aligning your travelling requirements with the appropriate aircraft.
