I'm planning a multi-destination trip (TLS -> AKL -> YUL -> TLS). Flight finders are showing me prices around €2-3000 for EACH of these legs, total up to €9000, whereas the (geographically similar) TLS -> AKL -> TLS round trip is reasonably priced (€1400).
It seems that I'd save loads of money if I booked return trips for each of the three segments, flying the outbound leg and cancelling the return leg each time.
But this sounds like a hacky solution to work around airlines' pricing policy. I've read reports online of airlines claiming money afterwards from people not showing up on the return leg, but not from cancelling it. Can anyone confirm that it works (or doesn't)?
