The banshees probably just didn't see the cheif. For all we know the Arbiter is on the other side of the galaxy, unless the thing the covenant found is the ark. And it most likely is. Odds are the covenant just don't care because they found the ark, and are beginning the great journey'. and think about it, the cheif could've probably taken those banshees.
