HI I wanted to double check I can access the Pier F & Wing F arriving at 3pm from Doha on QR in F but then not continuing onward until 8am on CX for a short haul flight.

I have no bags to check if that matters. Will I be able to get my CX BP online and then just go through transit? Or do I have to go landside and get my CX BP for the next morning.

In any event one way or the other I can go to the PIer/Wing F if I want to the evening before with out issue? Is the rule technically 24 hours before your flight as far as getting airside/using a lounge?

Thanks
