I got this by email today:
This year, see more of the world with The Economist
Earn up to 18,000 miles when you subscribe by 31 October 2018.
Clicking on the link doesn’t tell me anything about the promo, there is nothing on the M&M site and my google-fu has failed to turn up anything.
Anyone know how this works and what the ‘up to 18,000 miles’ means?
