Let's wait until passengers are respectively in London and Sydney before forming a judgment, but yes, at least an aircraft is on the way.
Yes, I am sure you will spend all of Xmas day finding every single negative report. God forbid, that when something goes wrong, QF can and does actually do a pretty good job under the circumstances. Do they always get it right, maybe not, but given all the information, in a country that from what we have all been reading, isn't exactly straight forward to deal with, have got passengers in hotels, got a replacement aircraft and will get most people home in time before Santa visits.
Even the SQ article that you shared had two totally different accounts. One not so flash, and the other, more understanding given the situation. That happens with almost every event.
There are two media headlines out of this diversion:
"Passengers STRANDED for Christmas in BAKU - "I was abandoned in the terminal and there was no one to talk too" said one flyer (insert photo of a 737)
or
"Rescue flight to get diverted passengers in Baku home for Christmas" "It was a long journey but they did they best under the circumstances" (and still insert that 737 photo)"
I feel that you honestly want the first headline.....
