Boarding was effortless, the food was outstanding, the seats in Premium Economy were extremely comfortable, and the staff and crew were excellent.

PREMIUM ECONOMY - excellent !Brilliant new plane. Excellent tv catalogue. Good food. Good communication and service from all friend Australian crew. Good communication from captain. Best travel experience in years.

I couldn't hear all of the announcements. It was nice when they put them on the screen.

I liked boarding the plane. The staff were rude, the food was appalling and the chairs the most uncomfortable I have ever experienced

One of the best Qantas business flights I've had. Quality product

Loved the staff. The economy seats could have been bigger.

The food was terrible. And the flight attendants were very rude. One flight attendant wouldn’t help a passenger lift their carry-on. Another flight attendant wouldn’t give a man an extra blanket. And they walked by not even looking at the passengers to see if they needed a glass of water.

I have flown Qantas multiple times in the past it seemed this flight the plane had less seat room or the seats were way less comfortable than before. Everything else was about the same. Thanks

Great flight and attendants. Seating is a bit weird. The extra price seats aren’t too worth it.

large seats was good. delayed flight, no food, no entertainment. plane was not cleaned, see rubbish from prior flights

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.

Boarding was great, and the crew were very friendly. The seats must have been a bit on the older side and you could feel some of the seat components through the padding. Also, the plugs did not work on the row's entertainment screen or charging ports. Checked bag was transferred for connecting flight, and we appreciated how early we had the connecting gate information.

It was Swiss. Our kosher meals were literally frozen solid and therefore inedible, and the crew didnt care.

Food was great. Staff was phenomenal. Seats were a bit hard and could use a lot more entertainment options as far as movies to choose from. WiFi was good. Overall great trip.

The flight was delayed, they didn’t even have water for the toilets or for drinks

It’s always a great time flying with united airlines.

Very old flight - time to retire it for newer airplanes

2+ hours delayed Outlet in row 12 did not work Tv monitors did not work Lights kept off the entire flight for at 5pm-7pm flight

Seated dude next to me even though lots of empty rows. But main thing was we sat on the tarmac after landing for 30 minutes because of, in the words of the dude who sat next to me, “operational incompetence”. We got changing directions about where to pick up gate checked bags. Pilot and flight attendant were awesome though.

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

I bought a ticket from Kayak. When I got to the airport, the was no ticket. I had to pay 5X to get to my destination. No response received from Kayak. I will NEVER use them again.

everything was fine. but paying for 1 piece of check-in luggage and denying passengers to board with carry-on luggage which by air line's standards does not fit is not acceptable. when one travels for a longer time one needs to have some essentials

Pearson Airport could not properly handle all the passengers who they needed to process in order to properly get them on board. As a result, I missed the departure of my flight from Toronto. The only saving grace is that Air Canada found a flight that only delayed me by one hour. However, this was no thanks to Pearson Airport!

I had a good experience. I liked being informed about the status of my luggage

The staff could have been friendlier. And Having the flight on time would have been much more convenient.

Old, noisy plane, bad coffee, delayed. Flight attendant was very nice.

We boarded 1.5 hours late. Long wait for the bags when we got to Mexico City. Long wait to get on plane with people mover truck. Friendly staff. They answered all questions as best the could. Such a long, long walk from the plane to customs. Thank you, Michael A. Burris Cambridge, Massachusetts USA

I was forced to check my carry-on bag, which I don't appreciate.

Terrible. Air Canada decided to wait for another flight. Due to the waiting, the weather got worse and connedting flight got cancelled. Air Canada said it was all due to the weather and didn’t pay me for the hotel. Not speaking of 3 hours waiting for my luggage. Never again!

Hard to criticize after the Crowd Strike dilemma. However, when Air Canada says they were "not affected," I expect that is true. My flight delays caused me to miss transportation connections. I understand these things happen, but I don't have to "like it."
