I have flights coming up on QF. Domestic, connecting to QF9 then a BA domestic flight. The flight is still about two months away. The QF website says that because it involves another airline, I have to check in at the airport. OLCI is normally open 24 hours before the flight. My flight from Brisbane departs more than 24 hours before my BA flight. Will they be able to check me in before 24 hours? Or will I need to check in when I'm in Perth or perhaps London?
