The Oceanic Six are: Jack, Kate, Aaron, Sayid, Hurley, and Aaron. At least that's my theory. Unlike this guy, I don't think the press would focus too heavily on the passenger manifest:
Didn't earlier Lost promos state that by the end of episode 7, we'd know every member of the Oceanic 6? If so, does that mean that Aaron is one of the Oceanic 6? . . . This, then, brings up the question of the passenger manifest. Aaron's name wouldn't have been on it. But, and I'm going to need some help on this, parents don't have to buy a ticket or reserve a seat for infant children, right? Couldn't this be the reasoning for Aaron not showing up on the manifest? Wouldn't this be enough to appease the press when the Oceanic 6 returned to the mainland?
Here's my theory:the press wouldn't care about the manifest. At least not as much as they'd care about telling everybody about Little Survivor Baby Aaron. Jack told us that eight people survived the crash, but only six could be rescued. Maybe Claire is one of those two, and Kate adopted Aaron. Or maybe something else. I can at least say this: I don't think the passenger manifest is the issue some people thinks it is.
There. I said it. Next mystery.
