Can you please process refund. Mum died and dad went to Pakistan to bury her after cancelling flight.

All was good, the only thing was it didn't run on time.

Overall excellent but the Captain kept the seat belt sign on for far too long, especially at the beginning and end of the flight. It was 2 hours after take-off before the crew were able to start the service (on an 11 hour night flight, reducing our sleeping time) and the seat belt sign on went on during breakfast (90 mins before landing) and was not turned off again until we landed. This made for an uncomfortable journey of trying to limit fluid intake because it was unclear when the toilets would be available for use.

The staff and crew on board were excellent. Business class however, was very weird. I thought we would have individual pods, but the way it was set up was unexpected. Not very private and If you wanted to lay down, you had to have an entire bed made up for you by the crew, rather than how Delta one works where you could just lie down whenever you feel like it. It was a 16 hour flight. I chose not to have my bed made, and that turned out to be a good idea because everybody who had their bed made had to wait for the crew to roll up their mattresses. So strange!

Food was not good. We asked for Muslim food and it was weird tasteless type of boiled veges.

Crew were pleasant, happy to be there and were a joy to be around. Entire operation was professional, well thought out and ran like a Swiss clock.

Couldn’t request a vegan meal somehow but I noticed other people getting them

The recline on the seat in front of me came back so that I was staring at the top of the man’s head in front of me the whole trip. He refused to bring his seat back up twice every time he was instructed to do so and only relented when he had a tray of good in front of him. And then right back in my lap!!! Horrible man!! I complained to the staff multiple times, but no one would address the issue. Otherwise, it would have been a perfect flight.

There was a snafu with confirming seats at check which left us in limbo for the second leg of our trip. I believe the ANZ app is not well integrated with the systems at the terminal resulting in this disconcerting error.

Flight was canceled due to technical issue shortly before the check-in counters opened. Passengers were rebooked on a flight three days later. Request to be accommodated on Air Tahiti Nui could not be processed. Customer service sorted out the refund after calling and being put on hold for almost an hour.

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

We liked the fully reclinable seats. Had center seats, so it was difficult to talk to spouse. Crew was great

Fine. Though no food or entertainment so the survey needs to be updated with those options.

This was a flight operated by Lufthansa. See me prior comments, which were meant for this experience. The CSA, Ashley, should be reprimanded if not fired for incompetence, being rude, and very, very slow. She was whispering to other CSAs, blaming my flight change on others, unable to give me a seat assignment, telling me could not help without offering any advice (I travel 200,000 miles a year and am a consultant to the airlines, so I know how this gets done PRETTY DAMN WELL). Then, she gave me literally the worst seat on the airline (yes, there were other seats open) - the one right next to the bathroom that was so bad the other PAX next to me left to move to another seat. My seat kept getting rammed (3x) by the crew with their carts (no turbulence to speak of), other passengers grabbing the seat to get in or out of the bathroom, and listening to the bathroom flush all night.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

Good dinner and nice plane.Smootz flight. Breakfast had no sweet option. Seats hardly reclined.

Too many fees (but that seems to apply to all airlines nowadays)

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Everything was very good. Boarding and takeoff were on time and organized. Had a good flight

Unable to initiate refund/reschedule the ticket #worst experience #lost 900$

Flight was delayed for almost 3 hours. Communication of gate change was poor. Email and screen said one gate and it was a different gate from that. Gate changed first to 64 B and then to 64 C. Originally it was 68B. 64C was not communicated properly!

This was a red eye return, so I doubt there would be anyway to make it better. Other than adding beds.

Direct nonstop flight was great. Flight was delayed and the crew announced a 2h delay on the sound system. 30 min or so later I hear my name on the sound system for immediate board. Several other passangers were late too. Reason: The crew incorrectly announced a 2h delay when in reality they meant a new boarding time at 2pm.

Plenty of room in the exit row. Sat on the plane an hour before taking off.☹️ Landed late and had to wait for gate availability.

Flight was on time early arrival better entertainment good staff.everything was excellent

Delayed leaving. On arrival we were taken to the airstrip and had to get off onto an over crowed bus, not all that passengers fit. Drove around the airport for 20 + minutes. Taken off the bus told to go upstairs 3 flights then all the passengers had to walk a mile or more , those of us old there was no one to direct us to were to go. I asked several people with no answers. Once I got to baggage claim my bags were not on the right bag claim. Once again asked for help and finally someone found my bags on a different carasel. Very frustrating.

Excellent host on board. Not so friendly check-in staff. Older plane with no food or entertainment due to short flight. Friendly captain and crew.

I don’t think there was entertainment? No mention of it. It was a good flight. Only complaint was my seat cushion was not attached and kept slipping.

They canceled the flight on us very close to the flight date .
