There's an Elseworlds graphic novel about this - Wikipedia says:
There was also one where just Jor El, Lara and Kal-El reach earth, but I don't think I ever read it:
Superman: The Last Family of Krypton is a one-shot comic book, published in 2010. It depicts what could have happened if Superman's parents also arrived on Earth.
Review of it here:

Slight correction on the Last Family of Krypton, it was actually a three-comic story (so not exactly a one-shot). He's never shown up since, though. I actually have it at home. Lex Luthor is closer to Jor-El through much of it that he is to Kal-El. That would be kind of awkward from our end (in this story, I don't remember there being a specifically "evil" element to this Luthor compared to the Shea's).
