Sydney to JNB (Johannesburg) ....... 13 hour sector, over 9 time zones, with very awake and very demanding pax..... you dont stop with the constant call buttons on the flight, get spoken to like you are dirt by the pax, and dont know whether you are Arthur or Martha by the time you get there, with the time zone changes ...... then the allowance is worth nothing !!! Thank god I dont have to do them anymore !
