I've had so much problem with their booking engine. Today, trying to check on domestic flights Sydney / Armidale for March prior to booking. After too long a delay, I finally get the March date entered for outward flight, then it throws me into booking RTW before I can put in a return date. I'm using my laptop, Window7.
Also, tried to change my home phone number to a mobile number, but when I put in the mobile number it keeps asking for an area code.
Got onto chat for both issues, but as usual, take forever so I cancelled.
Their whole website has become a real problem over the past few months. Unfortunately, I'm often locked into Qantas, but if they don't get their website working properly, I'll be flying other airlines.
