qgis - Sorting points to flight path route


Original question: I would like to sort my points in QGIS. See image


Restated question: The grid tool currently numbers by starting at R1C1 and going to R1Cx, then R2C1 to R2Cx. How do I number the points from R1C1 to R1Cx, then R2Cx to R2C1? Can the solution be applied after a regular grid has been destroyed (points removed) or does it need to be applied to a whole grid, assuming no option for this ordering scheme exists in the grid creation tool itself?


The point is to avoid the long 'row reset' or 'back to start of row' line as this wastes time and fuel, rather than moving directly down to the next row.
