I'm curious as to which work of science fiction can lay claim to furthest distance travelled in one trip by non-Wormhole, non-space shortening, non-teleportation means. So stuff like Q or the Traveller zapping the Enterprise somewhere; or the TARDIS' ability travel to any point in the Universe do not count.
I'm looking for the furthest distance travelled by a craft on one mission allowing for Hyperspace and other FTL.
To get a better idea of what I'm talking about I'll give this example:
In Stargate Universe, in the pilot, it's stated that Destiny, the main ship in the series, has travelled a vague distance of "Several billion light years from home (Earth)". The ship has been for 50 million years utilising an unknown form of FTL.
I want to know about voyages that trump that vague distance.
