Crediting miles to new account(s)
Hello
A few family members flew on United recently and have no status anywhere and didn't collect the miles. I just got an idea to sign up them to M&B. In total 6 people with sign up bonus make 48k miles - 8k mile each. If I transfer them to another account it earns me 49k miles (the account would be new too, so the bonus is here) for only 90€ as there is 15€ flat fee for miles transfer.
The question here is:
Can I sign up them for M&B now and claim for missing miles even the flights were flown 4 months ago? I know I cant get miles credited to BAEC for flights flown before registration for example...
Can I transfer miles from all these accounts to a completely new account with no transaction? I would make redemption asap.
Btw - They agreed I use whatever possible.
