Hi Mick,

I have exactly the sames issue.
Logged in as a French M&M member you will see everything in French. You can change the location, but not the language only.

If you change the location to say Germany and German, that will work for most of the information, but not for booking. This you have to do in French, as long as you want to do it with your M&M number.

For weero: Lufthansa.com will not change anything. As soon as you put your M&M number in it will change to French.

BTW: all letters from Lufthansa are also in French, even when you select English as your preferred languge.

Flockster certainly does not have this problem, because for certain reasons the UK website (his home) is in English.

I tried many things, but I could not find a workaround.
