I know a gal that works for one of the mainland airlines in Kona, and they give the rescues special pricing on flying the animals to the mainland, in addition to returning the kennels for free. I'm sure the rescues are on the list of charities the airline "supports". As far as I know they only ship small and medium sized dogs over. There are probably plenty of cats and large dogs already on the receiving end.
A no-kill shelter may still need to import adoptable animals, presumably all the animals being warehoused are unadoptable for some reason.
