I'm trying to put together an LONE5 ex SYD via Africa, preferably via LVI. There's a Comair flight JNB-LVI with a BA flight number which, according to my reading of the rules, should be possible within an LONE5; however, the OW RTW trip tool doesn't appear to include LVI as an option for Africa. Is this an oversight on the part of the software developers or is there some other restriction on Comair JNB-xxx flights?
