Really just of academic interest but I'd be interested to know what people think are the maxima for an AONE of the following:

1) How many different oneworld longhaul F products can you fit in (different = different airlines, not BA old first / new first / A380 first)
2) As for 1 but starting in JNB
3) How many genuine F segments can you fit in (allowing multiple segments with the same airline)
4) As for 3 but starting in JNB

My best answers so far:

1- LON-> DOH (QR F) -> DXB -> SYD (QF F) -> HKG -> YVR (CX F)-> DFW (somehow) -> GRU (AA F) -> LON (BA F) which I think gets you 5 [but are you ok to backtrack to Asia from Syd?]

2- JNB -> LON (BA F) -> HKG (CX F)-> SYD -> LAX (QF F) -> SCL -> GRU -> DFW (AA F) -> DOH -> JNB

3 and 4 I'll leave to the board..
