From my personal experience (from some one who doesn't hate qantas because its qantas) Qantas was an absolute mess when i flew to europe last crissy.
We were late to depart brissy as the scarebus 330 was busted. Had to wait 5 hours for them to get another jet. I had a connection in singapore of course and when I asked the helpful qantas lady about what happens when'if I miss the connection, she was about as friendly and helpful as a dog eating its bone. I was terribly sorry I asked. The cabin crew were not friendly on this leg. I guess i was in economy so I was one of the cattle they were moving across the planet.
The next two flights were fine however, only thing was my entertainment this was stuffed on the way back to singapore. And the perspex stuff on the window was damaged. It appeared someone had bashed it is with a bag or something. It looked shabby and dangerous.
Now this is where is gets to the best part of trip. On the way from singa to brissy i was put into Q's old 747-200/300. I can't remember which one exactly. This thing was an absolute wreck. I thought I was flying with Air Africa. The aircraft was filthy and old. Even the Lino in the bathroom had been pulled up. It was liking going to the only porta loo at a 100 00 person rock party. It whole jet looked absolutely trashed.
My father flew the 767 from sydney to brissy the other day, and he said it was a mess aswell.
So if I have a choice I won't fly with Qantas again. I've flown with etihad and even Lufthansa and have found that to be much much better. My father doesn't want to fly qantas anymore. He says the only reason he flys with them now is because of frequent flyer points, however after flying emirates to Singapore he says he won't fly with anything else.
So if thats the impressions and feelings we have with Q, I don''t think we are the only ones. Shame really.
