Again, Air New Zealand was great. They kept bathrooms clean, food was actually very good, New Zealand wines a big hit

The issue was with getting our boarding pases. There were issues with our arrangements that were made through Kayak. I am sorry to say that we will not use you again because of this. The flight itself was good and the flight attendants excellent.

Arriving at Coolangatta, rows 20 forward, took the airbridge across to the terminal. It was suggested to those from rows 21 back, that we take the rear stairs and to be careful crossing the tarmac. That was all well and good. However, when we got across to the terminal we then had to climb three large flights of stairs to meet up with those coming across the airbridge. No elevator! There were people carrying babies and elderly carrying hand luggage that needed assistance from others.. There was no option to turn back.

It was good for a short domestic flight. As no food ar entertainment provided, there should be a n/a rating available for those.

USB charging ports did not work on any of Air New Zealand flights

Economy was much nicer on the Air New Zealand planes.

At Coolangatta International it is difficult to hear voice boarding announcements when away from screen announcements.

Flew premium economy, well worth the extra. Much better seat size & space. Meals & snacks were lovely. Crew really pleasant. Internet is not great, not really useful for anything. Couldn't even send messages.

Everything was fine. Wish the wifi was free and included in the ticket price.

Nothing special short flight - all good - difference between 1 fudge and 2 fudge is obligation and thankfulness

Plane temperature was comfortable (not to hot) when boarding and waiting for takeoff.

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

We tried to upgrade to economy premium but were told this was not possible as we had booked through United Airlines (and Air Canada was operating the flight). This seemed silly given there was ample space in economy premium. Additionally, we had to wait almost 1.5 hours upon arrival to taxi to the gate. Otherwise, the crew were very pleasant and passengers were friendly.

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

headphone jack didnt work for the first flight and not much variety

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

Not as good as expected Air Can needs to improve totally rated on internet as worst

Smooth flight. As always dinner could have been more generous. Breakfast was great.

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

They lost my checked in luggage, why do I pay for my cargo not arriving at the same destination as me?

Overall good experience. The flight from Toronto to Denver does not have entertainment - movies to watch.

Not enough electronic outlets for charging in the Air Canada waiting to board area but the Most important thing….the plane was booked to only 40% capacity and my row of 2 other seats were empty. My row happened to be one of the few rows that did NOT have raising arm rests. The flight attendant made effort to seat me in a different row. I needed wheelchair assistance due to a cyst on my knee and struggled to move from seat to seat to get to the row. Those 2 empty seats tormented me the entire 15+ hour flight as I had to be upright the entire flight and was not able to elevate my knee. Lots of other passengers were laying down due to the arm rest being able to retract. It is a shame that he couldn’t be gracious and find a row that I could move to.

During the pre-departure safety briefing, the flight attendants rushed through the mandatory safety announcements in both official languages, making it difficult for passengers to clearly understand the instructions. Given the importance of these messages for passenger safety, this lack of clarity was concerning. Perhaps use a recoded message to alleviate this concern. Additionally, the flight attendants appeared to lack the professional attentiveness typically expected during a flight. Rather than focusing on timely and courteous service, they seemed more engaged in personal conversations than in addressing the needs of passengers. I hope this feedback is taken constructively and helps in maintaining the high standards of professionalism and care that travelers expect from a national carrier: AC.

They left on of my bags in Toronto and it took two days to get it.

The whole experience what excellent, from Anjou at the ticket counter to the attendants on the flight. Although it was an older plane, it was a very good flight. One of the best flights I have had on Air Canada!

Flight 3 hours late due to poor planning followed by a thunderstorm which happened after the scheduled departure time. Plane stuck on ground for 3 hours and flight connections missed without compensation resulting in new tickets needing to be bought.

Poor planning meant the plane was delayed an hour, then a thunder storm started and the ground staff couldn't work. Eventual arrival in Santiago was 3 hours late resulting in missed connections and the need to buy new tickets.

It was what it was. The crew were very supportive of my wife's inability to sit for long (without severe pain). I say the food was excellent because we bought sushi at Bento, pre flite. We did not complete the final leg (YVR to YYJ) as we were able to catch the last ferry to Swartz Bay. Thanks to Air Canada ( crew and network ) for the connections to/from SJO.

it was great only downfall was that the tvs weren't working but the rest was great specially the wifi
