Hey guys, wasn't sure where to post this, hope this works.

So I did a few favors for a friend of mine who has paid me back in the form of 2 delta buddy passes. My best friend and I were looking at using them for a couple week vacation early next year. We had decided on visiting Zanzibar, however I have just learned that the passes work on delta flights only, not any of the partner airlines. So we are now trying to find a way to get there partly on the passes, we could fly to Europe on delta, or Johannesburg, and take something local the rest of the way. Does anyone know a good local route to take? Something I may not have thought of? Thanks!
