I'm supposed to be flying MEL-PER tomorrow with a friend, and I made the bookings. It looks like he's not going to be able to travel as he's pulled up crook today and is off to get a test. On the QANTAS site it tells me I have to "separate" a booking if I need to cancel the booking for only some of the passengers, and it tells me I can find the separate option in the booking online. But I can't see it anywhere. I've called Qantas and am currently on hold, with an "over 2 hour" estimate. Do I have any other way forward here??
