If the people who do fly flew less often that would have an immediate impact on emissions.
It may have an impact on emissions but it would be negligible See above. Halving our use of air transport would cut emissions by less that 1.5% globally.
Halving our use of surface transport on the other hand would make a profound impact.
Ditto energy.
As has been stated above, the UK has reduced its emissions by 45%, but not by reducing air travel, it has targeted the major polluters.
