REMEMBER to use the voucher code1JA1KD when creating your BMI account!!
And if you are going to be creating 6 other accounts, make sure that the HOME address matches. Give some the same last name...
Play it safe and you'll avoid the dreaded "Ex-Gratia".
Ex-Gratia is what appears on your account when BA is auditing your account, when it believes that you got your points through means that they don't approve off.
Like- Buying a roundtrip ticket and not flying the return. Or creating a multi-city itinerary and skipping out on the last leg. Or selling your points (if they see that you've used your points to buy tickets for others MANY times) OR creating FAKE accounts to add to your Household account.
From the menu above - select Executive Club then click on Manage Account.
Then on the page you will see a Combine My Avios Link and that will work for you. (Mamon)
If you have problem finding the "Combine My Avios" Link, update your profile with DOB, save and go back to manage my account, you will see the link appear after that.
When you created your BA account if you did not fill out the details under Advance Passenger Information it does not have your birthdate. Without that the system thinks you are under 18 and is preventing you from having the option to combine miles.
Update that then from your main page select Manage My Account. once there in the center panel at the bottom you should see "combine my avios".
