I have a question regarding buying one way tickets or doing a stopover with a dummy flight back. I have to fly from Narita to Taipei to Hong Kong all on one way flights. According to the Cathay website, this would cost me over $1500 per person. However, if I create a dummy flight from HKG back to NRT, the price drops to only ~$500. This is on an Economy Saver L fare. My question is whether there will be any issues if I am a no show on that last flight back to Japan. If its no problem, do I still get the extra miles? TIA
