Follow this video to learn how to make your own paper airplane that can really fly. Acquire a sheet of A4 paper and fold it in half. Afterwards fold two of the edges towards the center line set out when folding. These should be folded in the form of two triangles. After doing so fold them downwards, towards the center line lower down. Fold another two triangles towards the center, one from each side. At this point a small edge will be formed at the tip of the two folds. Simply fold it upwards. Turn over the paper and fold it in half. Hold the plane from its tip and fold down the wings so that it will take the form of a plane and be able to fly. Try to match the wings evenly for better stability while flying.
