Just checked Manage My Booking for a forthcoming SYD-PER trip at the end of next month, the arrival time has moved 5 minutes, it says we need to confirm the change. The booking is a BA Avios Award, it says on Qantas MMB that as it's a travel agent booking the agent needs to confirm it. The prospect of being on hold for at least of couple of hours with BA if you can actually get in the queue doesn't appeal. There is nothing on BA MMB asking us to accept a change.Do we really need to confirm acceptance of arriving 5 minutes early??
