Been double dipping (HH and DL) for a couple of years, got the same email yesterday and thought the exact same question. Some of the bloggers have already commented, thank you for asking the question. For me, the “worth” valuation comes down to expediency and time & energy for the partner miles/point posting. My HH points have always posted automatically within a few days. My DL miles have never posted automatically and have required multiple DL communications, sometimes taking months to post. DL miles might be marginally higher value, not having to hit my head against a wall in order to receive the miles/points and thinking about the (highly appropriate) “SkyPesos” or “SkyYen” nicknames makes this decision a no brainer.
