The international flight from Sydney to Dallas had great food. I have travelled a lot over the years and this has been the most memorable in my experience so far.

The international flight from Sydney to Dallas had great food. I have travelled a lot over the years and this has been the most memorable in my experience so far.

flight delayed, wait in crowded gate. staff inattentive. had to remind them to get my coat from their closet. not many new movies, media choices were limited (nothing compared to Emirates.) Lounge was crowded

flight delayed, wait in crowded gate. staff inattentive. had to remind them to get my coat from their closet. not many new movies, media choices were limited (nothing compared to Emirates.)

Initial flight was cancelled so moved to an alternative flight. As a result, stuck in a middle seat. Flight then place in holding pattern prior to landing resulting in a very late trip home.

There was nothing I didn’t like, prices a little lower would help

Flight delay was informed at the last minute. Food quality is not up to Qantas standard I was unable to book an online boarding pass on any of my 6 flights.

Following a marathon flight riddled by delays and changes from Santiago, Chile, my flight to Melbourne from Sydney was on schedule but I was transferred to the next flight. The reason by ticketing and the floor manager was I missed the entry to flight by one minute! That's right, the emphasised that if I was 1 minute earlier I would be on the flight. I asked what was the point them emphasising 1minute overdue and how that helped me or the situation. They didn't care at all. Replying that if it was one minute earlier they would've done something and smirking delivering the information. Australian's do call Australia home, Qantas calls Australian's suckers.

Rescheduled after ticket purchased and issued, not 2 or 3 times and not a fourth but by 5 times, by Qantas, that's right, 5 changes! Forcing an overnight stay in Chile and need for visa. Qantas can no longer provide basic services as a national or international service provider. Professionalism is extinct and the provider needs to be mentored and educated in perfecting who to operate as an airline. Qantas is the spirit of Australian dissatisfaction.

Amazing! Was put on the earlier flight and I requested for an aisle seat and was given it. Thanks Qantas!

The staff we fantastic and seemed to work very well with each other
