I already have a Together account with a friend who I travel with often.

Another friend will be travelling in SAS economy to the US this week with her mother. I suggested to them that they open a Miles&Bonus account because of the attractive earnings, and individually they will earn about 7,698 miles. Plus, I am not sure if Aegean still awards a 1,000 miles sign-up bonus. The mother has said that she probably won't fly again.

7,698 miles would be enough to book an economy flight from VIE to ATH, but with taxes (€33.78) that makes almost no sense. So I mentioned to them that another option was to pool the miles so that the daughter could book a business class flight instead, but as they don't have status that's not an option.

With the Together account, if I invited them to my account, I could book the flight for the daughter. The only problem there is, the remaining 2,396 miles.

1.) Does Aegean still award a 1,000 miles sign-up bonus?
2.) If after booking a flight I remove them from the account, do all the remaining miles stay in my Together account? (logically I think they would)
3.) Would inviting them and then removing them restrict me to inviting only 1 more friend in the future, or 3?

I see no issues here regarding the terms & conditions of the Together account. As always, I'm grateful for your help/advice.
