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.

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

United flight from SFO to PDX was cancelled. I will ask for a refund. Had to book on Alaska

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 pilot tried to make up for lost time due to delays that were out of her control. She communicated the issues openly and clearly and made every effort to do what she could to alleviate issues.

Just a hiccup being added to the NZ Traveller Declaration a bit late.

Absolutely nothing flight was cancelled and delayed for 2 days. Barely a heads up I want a full refund

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Best airline! Always friendly and welcoming. Skyclub was great and loved the fast free wifi on board. I also love that you can pre-order your meal on the app!

Atlanta boarding crew at gate were filled with arrogance and were disrespectful. In flight crew showed indifference to the needs of passengers. This is about the flight from ATL to BDL.

The plane was FREEZING SEATS UNCOMFORTABLE Otherwise smooth Thank you

Boarding was chaotic. I didn’t finish dinner because I went to bed early. Breakfast omelet was overcooked and tasteless but croissant was better than usual. Plane was dirty—crumbs in every seam and lavatory was poorly maintained (paint peeling, etc.) and toilet paper had not been refreshed before takeoff. No cubby for storage in first and seat was narrow.

Boarding was somewhat chaotic. Unable to evaluate crew or food/drink because captain kept them seated due to turbulence. Have no idea if entertainment was offered.

West Jet has a horrible boarding process and the seats have no cushion.

Everything went smoothly. I didn’t like that when I booked in the main cabin my wife and I weren’t seated together. One would think when booking on an option that allows picking your seat. They would put you and your travel partner together. Had to call to get it sorted. They did fix.

The gate area was incredibly short staffed, with one representative manning 4-5 flights, which caused a 3 hr delay in boarding even though the plane was all ready to leave. Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

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

Wheelchair assistance was not complete. The person left me at the departure gate without informing the groundstaff of my requirements. I had to walk to the departure counter to ask for help to reach the plane door. The crew informed me that in future they were not allowed to help passengers like me, senior citizen and Wheelchair passenger with placing their carry on bags in the overhead compartments!

Flight was delayed by over an hour and gate checked bags took 15 minutes to be delivered to the jet bridge.

Seats are way too snug for my hip to knee ratio and the recline on the seat in front of me made my experience worst. My legs had no room at all. Not a plane for people 6 ft or over unless you fly first class.

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

It took 66 hours to get from Seattle to Tel Aviv. As a minor, I was left for more than 12 hours in Toronto and Frankfurt without hotel and food vouchers. It took 5 layovers. It was insane and not okay

It was delayed but got us to YYZ. I had great copassengers.

Flew SEA-CA, then CA-NRT. First flight was short but very uncomfortable, dirty, and had very small overhead storage space. The seats and fans were not cleaned and had visible dirt on them. Second flight was perfect.

My second flight ended up being through United and it was fine. Again, just frustrating that it was so late.

My experience was pretty frustrating because the first leg of my flight on United (though booked through Air Canada) was delayed causing me to miss my connecting flight on Air Canada. This could have been an easy solve as there was a direct flight later that morning via Air Canada that they easily could have put me on which would have only gotten me to my destination 2 1/2 hours later but because United and Air Canada don’t seem to have good communication they gave me the run around both telling me to talk with the other which I did three times to no avail. I ended up taking the delayed flight and getting on a new connecting flight which ended up getting me to my destination 6 hours later and I missed the event I was planning to go to this evening.

Everything went smoothly and as expected. We were on time and one flight arrived early.

First time flying Air Canada and the trip was very pleasant! They did a great job getting us out of Toronto and into Rome (early!) For an international flight it was very enjoyable.

This is not a Business Class equipped airplane and even the crew apologize before take over BUT BUT Air Canada charged full business class fare

All was good, except our baggage was lost for most of a day. We are thankful that it was found quickly and delivered to our hotel. Rouge was fine outside of that problem.
