We know Aang was the last Airbender (titularly) and that Aang had one Airbender son, Tenzin and that Tenzin had 3 Airbender children Meelo, Ikki and Jinora, but that doesn’t mean Aang’s family is the only Airbender family.
It certainly seems that way, and I’m not going to say that anyone is wrong, but going back over the episodes that have air(bender)ed, no one says that Tenzin’s family are the only Airbenders.
I’m just happy we’ve re-populated with Sky Bison, so that means the proud tradition of Airbending will live on.
