Here is one of those odd little quirks that few people know about.
It may be that you have a small number of Miles & More miles languishing. Unlike BA, there is very little that the average flyer can do with a small amount of Miles & More miles – there is no cash and miles option, unlike Avios, and European redemptions are laughably expensive.
A short haul European flight that would cost 9,000 Avios points plus £27 in taxes will cost you a shocking 30,000 Miles & More miles plus over £100 in taxes! Even a domestic return economy flight inside Germany would cost 25,000 miles plus a lot of taxes.
You can, though, cash out Miles & More miles via the Heathrow Rewards shopping programme (you need to log-in and go to the redemption page to see this offer). You need to redeem a minimum of 7,500 M&M miles, which gets you a £20 shopping voucher valid at Heathrow, Stansted, Glasgow, Aberdeen or Southampton airport. Each addition 1,875 miles gets you an additional £5 voucher.
Is this a great deal? No, of course not. Is it a useful way of disposing of a small quantity of Miles & More miles, especially ones which are close to their expiry date? Yes.
(PS. I am not saying that Miles & More miles are totally useless. There are good long-haul deals in there, especially as M&M members can access redemption seats that are blocked to other Star Alliance airlines. They also give Senator (Gold) members an on-going 50% discount on a second redemption seat when two people travel together. However, if you only have a small number of them and don’t see yourself getting to a large number before they expire, you could have a problem and this could be the answer!)
