My advice is to sign up for them you get 1000 bonus miles for sign up and then transfer the miles for 19E to your account. It can be only in thousands so if you short a bit, use booking.com to make it for thousand. You safe 2 places in together account for such a small miles. A3 is very strict today so in advance I am telling you they will want proof that you dont use the account without knowing of the owner - e. g. ID + something that shows address used in registration.
