I guess 30 mins wasn't too bad judging by some of the responses here. Just to update you, it was 45 minutes before someone picked up.
I did ask why it was such a long wait time, and the response was that they were having "technical difficulties" yesterday.
I've been using Qantas almost exclusively for 8 or 9 years now, and I have seen them decline, then heavily improve recently (last 2 years) and now I'm starting to see complacency slip back in where they will suffer again if they keep this up.
Customer service is the most important factor in running an airline, and to be honest, I think that members who are actually loyal with the airline (Silver - P1) shouldn't be on the phone for an hour.
And in my case I had to call because I needed to make a booking which couldn't be done online, or else I would have.
Very poor Qantas.
