Sadly I can't reproduce the online timetable page, but all 12 JNB-CPT flights today are 'operated by MN'. Click on INFO to see 'Operated by
Comair Ltd'. Is that 'misdescribing' by BA? (I have read before that they are not op MN.)
No, that's not a misdescription; and yes, they are ops MN.* But it helps to ignore this, because it will only sow confusion unless you really want to get into the technical ins and outs of it.
BA flight number = British Airways flight.
MN flight number = Kulula flight.
"BA6441 operated by MN" has a BA flight number but does not have an MN flight number.
* The kind of misdescription elsewhere which is confusing is something like "BA6441 operated by Kulula". That's just wrong.
