Putting money into KFA is not "investing". KFA is not an investable entity at all.
It is a money losing scheme.
As it stands airlines is a very tough business which very few companies across the world run profitably. Apart from the self created problems of KFA, the industry itself has a lot of problems. The bulk of costs incurred in running an airline is beyond the control of people running it (fuel cost, airport charges etc.)
Having said that you could still make money on KFA stock if you know how to time it (I don't). In any case it should not be thought of as an investment.
