Although the flight was delayed and out of their control, we boarded and were underway in no time. The crew were great, the service A1 and the meal was superb ( I had the chicken dish). I would fly with Qantas again, anytime. Noel Swift

My flight with Qantas was excellent, the crew were exceptional, the food was very good, and the seats were surprisingly spacious and comfortable. I was extremely disappointed when my checked bag did not make it onto my connecting flight, but was pleased with the ease of filing a report of a missing bag with Qantas at the Auckland airport - there, my pleasure ended. I can see, with an apple tag on my bag, that it is still in Sydney and has not moved in more than 30 hours. I shared the tracking information with Qantas and was assured when I filed the missing bag report that my bag would be delivered first thing the next morning on the next flight from Sydney to Auckland. Qantas' missing bag tracking feature still lists its status as "searching for your bag, check back later" more than a full 24 hours after filing the report despite my having shared tracking information, a photo of the bag, and calling the customer care line and being assured that an "urgent action message" had been sent to the team in Sydney. The lack of communication from Qantas' customer service department and the lack of action after an incredibly expensive business class ticket price is outrageous and has, definitively, affected my willingness to consider flying Qantas in the future, much less on long-haul international flights with high cost airfare.

I want a refund. I had to switch flights and buy another airline ticket because this one was delayed.

Helpful staff when I felt unwell. Qantas need to have an audio/music channel so you can listen to various music/.artists

I'd like to see AA's flight safety record clearly and prominently posted online.

It was a good flight and no complaints. It just wasn't anything that was better than any other flight.

Not great. The inflight entertainment was all on an app, and I did not want to watch a film on my phone. Also, the range of options of films was limited.

by the time they got to our row, they were out of some of the food options. games and movies were great but maybe more game options like tetris or pac man would be great

Great as usual, some delays but well communicated and made up for in the air

Inflight entertainment, poor that there are no headrest screens on aircraft used for an international flight.

Knees in back from passenger behind, limited seat pockets, no entertainment.

Jane at Sydney International airport check in was amazing. She set up the whole experience to be a positive one.

The flight ticket were not reimbursed on Jan 22nd from Auckland to Wellington. Very Very dissatisfied.Please reimburse the ticket of my onward travel.

Flight was delayed both directions but once in the air was ok. Boarding out of Melbourne is just a mess.

Over four hours late. No entertainment without paying and same for food. Asked to check in at original time even though we were told it was going to be very late leaving. Way too long time to hang around the airport. Arriving to Sydney luggage did not arrive for an hour. Had to get staff to go and find out what was going on. All this made for a very long day and night for a eight hour flight.

Very disappointed with my recent Jetstar experience. Firstly, it was extremely frustrating that we had to pay extra for basic things like in-flight entertainment and meals. Other airlines provide these essentials even with standard tickets, but Jetstar offered no comfort or amenities without additional charges. For a long international journey, this made the experience very uncomfortable. On top of that, there was a delay on our flight from Melbourne to Bangkok due to parts replacement, which was already inconvenient. But the biggest issue was the massive 5 hours and 15 minutes delay on our return flight, which completely disrupted our plans, caused unnecessary stress, and impacted both our time and health. Jetstar provided vouchers, but they were not nearly sufficient to cover proper meals or any meaningful service at Bangkok Airport. After such a long delay, this felt extremely inadequate and did not compensate for the inconvenience we faced. Overall, this has been one of my worst travel experiences. I am extremely disappointed and will not be booking with Jetstar in the future. I strongly request Jetstar to provide additional compensation for the significant delays and the discomfort we had to go through.

I was treated poorly in Dunedin by check in crew, then my bag was lost in Auckland. Never again.

They added the weight of my back to the carryon luggage and charged me NZ$75 for being over 7 kg.

Flight departing too early at 06.15 Difficult to get to airport

Plane was more than 3 hrs delayed as the only plane on that day. Had to wait 1 hrs in the plane which was very unpleasent.
