Hello, need some clarification :

I am Frequent Flyer with Miles and More and Gold Status with AA.

Should have flown with Lufthansa to Miami but the flight was canceled and rerouted with British Airways.

Now I would like to redeem my 'retroactive miles', but :

1 Can I do it with Miles and More even if BA is not in Star Alliance ?

or

2 Put them in AA (tried the ticket number on the website but it is not recognized)

Thanks forthe help !!!
