Solar panels to generate energy

Make visible in the app how many people are flying on green fuel on booked flights, to encourage other people to do.

In a week/ some days before a flight, do sell “stand by tickets”, to a cost of approx. Euro 50 in Europa, Euro 200 intercontinental, , to increase the cabin factor.

I would use my skills in optimization and deep learning to learn what frequenzies and time schedules that maximizes the load factor of each aircraft in the fleet.

Find ways to allow tax-free purchases to be done in departing airport and to be picked up at the airport were I land. It could save a lot of weigh/fuel.

If biofuel could be bought/added with points, people could spend their "soon-to-be-expired" points on biofuel rather than something unsustainable.
