    Question in the title, is there any good way of doing that between two Location objects?

    What exactly is it you are looking for?
    An Entity or a Block? Use World#rayTrace
    The distance? Use
    Code (Java):
    locA.distance(locB)
    The fastest way to go there, constraint to a certain x-z-plane? Use Dynamic Programming

    To see if there is a path of air blocks inbetween two locations. That's what I'm looking for.

    In that case, use World#rayTraceBlocks. You can define a maximum distance (that you can get from using the method described above). If RayTraceResult#getHitBlock() is null, you don't have a block in between, if the result is not null, you have a block.
