On an occasional basis, for what ever reason, sometimes the OLCI process on the print out will read, "online check in is not available, please approach a customer services officer at the airport, who will assist in checking you in".
Or that you have to present your passport to be dipped and swiped. into a slot in QFF's keyboard at the airport.
It reads the MRZ lines on your passport, below your photo.
Don't just go through ougoing immi and iint security screening, without have your passport dipped and swiped into QFF CSA desk system, or you might get stuck, ie, you might be able to have passed the border, ie, outgoing immi and int security screening, but you can't board, and you have to hold up people at the gate who have checked in and others have got the green light and beep, and yours is red and a buzz.
(((Once at ADL airport, I was on a linked PNR ADL - PER - SIN, had done OLCI, and had my dom BP, and the reader kept buzzing red, then gate CSA must have known, I didn't know, that for an int flight, you must have your passport dipped and swiped into QF's system))).
In the past, at an Aust airport, I have always gone to a counter to check in, but this in 2013 was my first int flight as an Aust citizen, and not having approached a counter, but had done OLCI.
Now, even with OLCI, I always go to a counter and get Aust passport dipped and swiped, at counter or the int lounge.
So, at the gate for boarding, I don't get the red light and the buzz.
