Frequently flyer number should and could have been put on at the time of booking as I gave the number when booking.

Not at all satisfactory. I had stomach upsets after taking food. Quality of Asian vegetarian meal was awful. Further there was no snacks/ fruits/ biscuits available as in between snacks.. only peanuts and pitzels.. except courteous staff rest of my experience was far from satisfactory

Staff was very courteous. Plane was clean and quite spacious even in the last rows. Veg food could have been better.

Everything and everyone were excellent except for the charge for using WiFi; there was no escape from this fee except to not use it.

The crew and the food were excellent. The plane was kept quite clean.

Very bad. Flight got delayed and missed my transfer flight twice. Had to stay overnight in Hong Kong and the next flight booked was also delayed.i had the worst experience flying from Singapore to San Francisco. Lots of delays and rerouting.

I booked wheel chair for my mother but she was told to walk by herself in the middle of her way to the gate. She had to board a connecting flight under a time crunch and this was unfair to leave her to walk. Other than that they had no complains about anything else.

The flight attendants were very helpful, efficient and courteous in helping everyone!

The flight from Hong Kong to Hyderabad didn’t have any power points to charge my mobile. Given we are no longer allowed to use power banks, giving customers the ability to charge even on short flights is critical part of the overall experience.

Seat was very old. Didn’t easily go up and down. Flight Attendent had issues moving the seat. Condition of the seat was ok. Parts were peeling off by the foot area. Food was ok. Ran out of the dish I wanted so got the beef. Beef filet was very tender but the sauce was a little strange. Disembarking was very easy.

I never flew with alliance. Kayak is a joke and none of the flights or times were correct. Won’t ever use kayak again

I missed my flight due to unforeseen circumstances It was, however , an excellent price !

Loved the food and beverages available, spacious economy class, excellent entertainment

Very good overall. Highly recommend for all flying to Australia

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

We had bulkhead seats in a A380 in the upper deck in seats 31 D and E. Storage was very limited other than in overhead bin - which is not within reach when in seat. Yet paying same price as others in premium economy who have a lot more storage within arm’s reach. Seems very unfair.

Good check in and helpful staff. Delayed for 1 hour. Took about 45 Mins to get baggage’s at DFW . Food was average ( Hindu meal ) . Overall it was good experience

My experience was great overall. Tanya was particularly friendly and helpful the entire trip. I was very pleased with her customer service skills. The plane was an older aircraft but the entire way was comfortable with barely any turbulence at all. Qantas should speed up its fleet renovation. Totally recommend using this airline.

When I originally booked this flight, I was expecting to travel on Qantas. When the itinerary changed and the long-haul segment was operated by American Airlines, we were disappointed but remained open-minded. Unfortunately, the overall service experience fell far short of expectations. This was a long-haul international flight. Getting up periodically to use the restroom or stretch is inevitable, especially on flights of this duration. However, each time we stood up, we felt as though we were inconveniencing the crew. The tone and body language often suggested that we were in the way or disrupting something simply by moving about the cabin. As a result, I avoided getting up as often as I needed to and was physically very sore upon arrival. Meal service was similarly impersonal. The options were presented in single words “beef or veggie,” “pasta or beef” without any description of what was actually being served. There was little engagement or courtesy beyond that. Even simple expressions of gratitude were often not acknowledged. I am accustomed to no-frills travel and do not expect luxury. What was disappointing was not the absence of extras, but the absence of basic warmth and professionalism. On a long-haul international flight, small moments of courtesy and humanity make a significant difference. In this case, the experience felt transactional and dismissive rather than welcoming. I hope this feedback is taken constructively, as there is a meaningful difference between efficient service and indifferent service.

Qantas is always subpar beyond comfy chairs for a domestic flight

Our AC flight was canceled not once but twice on the same day to Quebec City at Toronto Pearson Airport. 2;30 AC and 9;40PM AC flight. After having our 2:35 flight canceled, we were bumped the second time because of large student groups visiting Quebec City. We were sent to Montreal on an 11:30 flight which landed close to 12:45AM. We were given a hotel room at the Marriot Hotel next to the airport. We had less than 4 hours sleep before we being taken to the airport for our 7AM flight to Quebec City. We didn't have much time to use our vouchers given for breakfast once we had cleared customs for the 2nd time since leaving Toronto Pearson Airport. We missed a full evening in Quebec City and lost our hotel room for the night. We were exhausted the next day and missed an excursion we had planned. My wife and I are both seniors in our seventies, and we weren't happy to be treated in this manner. Air Canada could have used a larger plane to accommodate us and the other ten or so people that were bumped from their flight to Quebec City in order to accommodate student groups. We will endeavor never to fly Air Canada again in future and we will not recommend flying with this airline to our friends and families.

Better to not serve food if those are the options

It was a good experience flying Air Canada for the first time

They did not let us board because one member needed a transit visa, which was not evident at the time of ticket purchase.

I was charge a baggage checking fee $68!! I volunteered to check my duffle bag which usually goes under my seat!

Boarding - 3 of 4 flights were delayed and the gate staff did an ok job of managing the lines for boarding. Lots of standing around in line - more than typical. Crew - accommodating. If you are looking for warmth, you will not experience it with AC. But I appreciate their hard work and relative efficiency on 8+ hour flights. Comfort - My first 2 flights were cancelled the morning I was due to depart. AC rescheduled me on 2 new flights that created only minimal disruption and change to my itinerary (a longer layover, several hours difference in arrival time) and provided a 15 dollar food voucher for the layover restaurant which was the equivalent of a measly sandwich. My seats were changed which is a huge issue for my physical size as I require additional legroom for medical reasons, and I was put in a very uncomfortable seat without the option for seat selection. The bathrooms were incredibly dirty and foul smelling to the point of being nauseating and I was next to it during my longest of 4 flights. Entertainment - I always travel with downloaded entertainment on my own devices and a power bank, and am glad I did! The entertainment was completely non functioning for my 8+ hour flight home. We were provided a 15% or 50 dollar voucher on a future flight by way of compensation. Food - always just poor to mid. I also travel with my own food when possible as in flight meals and snacks taste strongly of packaging. Overall, this was a poor to mid experience, and I am resigned to the fact that airlines are never going to improve.

I did not like anything because the flight was cancelled yesterday and I did not get to arrive on time in Toronto as I was rebooked with another airline. This caused me to be really stressed out as I am an individual with back injury and to be forced to stay longer in an airport to accommodate a change of airline and the transfers associated with it Due to this I am probably not going to book through your website to eliminate this potentially chaos in the future

shittiest airline in the hemisphere. To improve - start thinking you're flying people, not cattle

Easy boarding, inflight refreshments came on time and comfortable seat

Flight attendants were ok. But it was a full flight.
