No, I think constitutional rights apply to the private sector as
well.

You should read up on that. (Hint, it's governmental action only.)

Can an airline have a policy where blacks are seated at the back of a
plane?

Regardless of the economic or PR impact such a policy may have, can they

No; but not due to constitutional restrictions, there are other laws
which prohibit such (or rather, which define penalties for doing so)
