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

The American/Hollywood movies in the entertainment system lack english subtitles, they tend to have only arabic subtitles. Coupled with the low quality airplane earphones and cabin noise, it sometimes is difficult to follow the movie dialogues.

The Qatar Airways staff pre-boarding and also on the flight from Dallas to Doha were incredibly mediocre and arrogant. Consider retraining these individuals Other flights were ok.

Seating is terrible, having seats so crammed is unacceptable for a 15-hour journey. I cannot stress enough how uncomfortable it is to sit in such an aircraft. Leg space is roomier in a domestic aircraft. I have not experienced this kind of crammy seating in domestic flights either in the US or other international airlines overseas.

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

There was not enough food for everybody. Some dishes were missing.

Boston to Doha was great but Doha to Dhaka was the worst experience.

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

Being a QR Platinum member traveling in business class, I expected the staff to be more courteous. Unfortunately, the lady staff was rude attending business class 1K side.

Overall experience was OK. Seats were truly uncomfortable for such a long flight. Food quality was mediocre at best. The staff was great though!

Food was good, attendants were friendly. Seats were not comfortable. Did not receive any amenities such as eyemask or earplugs that would have helped sleep. Additionally a large group of passengers boarded very late into boarding and were a disruption for almost the whole flight. Flight attendants did their best but the kids were making so much noise, kicking seats, and half the time no adult was sat with them so they weren’t being managed.

My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.

Much better than the major US Carriers especially in Biz Class.

I wish that the meal included a vegetable or even a salad instead of couscous! Why serve chicken with rice AND couscous? Service was good overall though a bit lacking in friendliness. Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!

My wife and I had a row to ourselves after moving seats. There were no TVs and you had to buy food. So we did nothing but had a quick nap. Flight was fine.

The male attended that served are section was a snob. He did not answer my call light when my wine spilled all over the floor. I did not push it again or drew his attention to it. He just ignored the call light when he came to give us our meal, serving the people behind us first. I did not push it again or drew his attention to it to see his reaction. It was so obvious that he was ignoring us. We were in premium economy!

Georgian Airways check in staff initially denied us, because they thought passengers required transit visas to transfer on connecting flights. This required 70 minutes for them to call multiple people to confirm how transfers worked. They did not apologize once accepting our check in. Onboard, the four hour flight gave stale bread with spam slices as lunch. The only included drinks were still or sparkling water.

Not a good one this time. The absence of internet without any information/notification ahead was really the unacceptable part. Also this new A350-900 has a serious legroom challenge for economy seats. It’s more like a medium-haul flight legroom configuration.

Not great , just ok . I expected better food but it did not deliver . Flight staff was ok . The guy at the drop off bag counter was the only saving grace in this whole trip . He was pleasant, friendly and very helpful . You couldn’t ask for a better assistance from him .

There was 2 hours delay before boarding and 2 hours delay after boarding while waiting in the plane

Very good crew. Food service above average. Seats very small for a 12 hours flight.

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.

Crew was pleasant and efficient. The speaker system for instructions was hard to understand

My experience was poor with customer Services. Please consider flexibility with cancellation due to emergency health condition. Thank you.

Terrible. Flight was delayed for hours and we ended up arriving at our home at 4am after 20+ hours flying.

Disappointed my flight was delayed to TO as i had a connection to make. Ran through the airport I made my flight but I initially had 1.5 hours to connect. Unnecessary stress!

From my experience, I see there is room for a greater mixture of cultures, for example, a mix of the nationality of cabin crews, food, music, food, etc.

Flight was cancelled around 45 -1hr minutes before scheduled take off time due to mechanical issues we hadn’t even boarded yet. Had to reroute to Orlando so someone had to drive 2 1/2 to come and get me… the alternative was go through Toronto and get a later flight which didn’t work for my schedule. The flight attendants barely gave anyone a smile…not the same as flying when a client/passenger was important. Very disappointed. By the way I have never ever made a complaint online about any company with feedback…even when I probably should have. The only good experience was the boarding desk associates who were very professional and got me on another flight with my checked bags…very nice team.

Actually as my experience with air Canada from Canada to Newark it was crazy for me because it was a lot of delays which for me it shouldn’t be like that, but I was able to coup with it so that was my experience I hope next time they will do good on that thanks.

Delayed delayed delayed cancelled and all we got was $60 food or beverage Embarrassing I'd say

It was fine. There were a couple of mechanical delays prior to takeoff but it was overall a quick and pleasant flight.

Mixed experienced. Nice staff. Spacious 787 better than cramped Airbus, though my seat was broken. The bad: Way overpriced ticket and charged for food despite 6 hr flight.
