I've used the auth app for ages. it works great and definitely gets around the text issue around the world. A definitely good QF enhancement
but the optus issue of course got me thinking about difficulties caused at domestic airports for optus customers today and QF - checking in online, bringing up a BP to scan for bag check, let alone lounge entry or boarding. I can imagine a few lines at desks for printed BP's potentially for those customers who had no connectivity (could have used airport wifi I guess).
Another reason why removing ability to print BP's from kiosks was probably a bad move.
Hopefully nobody flying was badly impacted by this. Didn't seem like MEL had many delays today that I could tell so that bodes well.
