I know this must have been discussed a lot over the years, but despite lots of searching, I can't find any posts that talk about it (searching only turned up false positives, posts that don't actually contain the searched term).

If I want to drop the last segment of an xONEx without paying the re-route fee, what's the best way to do it? I could just no-show, but that just feels wrong. This would be a Comair flight with a BA code out of JNB.
