Cabin crew on our flight showed lack of any customer service gruff and acting annoyed if you asked anything and I mean anything Example a man on the seat over dropped his beer on my husbands blanket We asked if we could switch out blankets cabin crew Said. No we don’t have any extras OK well can you take the wet one Cabin crew looked disgusted and annoyed Took it no OK or yes just a growl

Quick flight. But cabin crew were very noisy and talking too much, especially when we were seated at the back of the plane trying to sleep through the night .

My ticket was for Premium Economy and all the seats were taken, I was placed in Economy class and I’m looking for a refund.

The delay was an issue. Other than that. Every thing good

Staff didn’t check cabin well for landing seemed more interested in chatting to each other. Food was poor and differed from pre order.

We were in the last group to be called to the flight - which was 30 minutes late taking off. While we were lucky enough to have been given bulkhead seats (due to a medical condition I’d told them about beforehand) the seats weren’t particularly comfortable. A crying baby for the whole trip made things worse, so the crew managed very well with coping. The final thing I’d say was that there wasn’t enough food served during the flight.

Very good. Glad we had Premium for the flight out.

We flew Upper Class from London to The Turks and Caicos. Check in was amazing. Our ldriver too us directly to a special entrance to terminal 3. It took 10 minutes to check in and clear customs. Amazing! The VA lounge is large and comfortable. Boarding the flight was easy and without a wait. The crew was excellent. But the seats were awful, strange and uncomfortable. Having a comfortable flat bed seat is the reason we pays 1000s extra. The VA 787 uses a reverse herringbone configuration. Look it up. You have your back to the window and are facing the aisle with no privacy. Turning the seat into a bed requires assistance from the crew so not very spontaneous. . The food was ok. A bit tasteless and meager portions. Had to pay for WiFi. I believe VA has other configuration on their dream airbus flights. Lots of stuff about all this on YouTube where you can see what I have been describing. I can not recommend taking VA on a long flight with these seats.

From the start everything was perfectly fine. First meal was fantastic. Breakfast needs a lot of work and food was overcooked and not very nice for breakfast. Staff were fantastic friendly nice they came round and check we need anything else to eat or drink

From the start everything was perfectly fine. First meal was fantastic. Breakfast needs a lot of work and food was overcooked and not very nice for breakfast. Staff for a fantastic friendly nice we came round and check we need anything else to eat or drink

The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

Generally good. The crew is excellent. The food could be better.

Excellent apart from transport to actual plane 10 minutes from the actual gate , walking out in the tarmac in the rain and having to climb stairs to enter while holding luggage.

They wanted to close counter although they did not provide the wheelchair requested which ended by going alone to transit security and lost long time and they did not want to wait .

Business class in the second leg - CDG-EVN was a disaster.

Everything went smoothly with Air France. There was a delay in departure which seemed to relate to the immigration services being short staffed.

Food could have been better especially the breakfast. Overall it was a good flight

I have used Air France and KLM many times it will help if they change their menu's feel like it's been the same for years!!!, Especially the breakfast. Overall the flight was good and enjoyable.

No bording was given for next trip on same carrier, food was very moderate.

Crew was professional. Boarding has few seats . Since the plane was not full would have been nice to change seat on the internet

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

Two flights,both poor. No entertainment. Cramped and uncomfortable seats, little space, the rest was OK. Staff were acceptable good.

The crew was doing their best on an old plane needing updating. Chairs that creaked and wouldn’t stay in position. My tray table was unusable as was on-board entertainment due the audio needing usb earphones (that were not provided). Prior to boarding in Toronto and despite being scheduled for a wheelchair and assistance, we were dropped off by clubcar without a wheelchair which I found myself by a gate. Due to no boarding gate assigned at that time we waited and when it was, it subsequently was moved from 64 to 95. No help could be found so I pushed my husband’s chair to that furthest gate in the airport at the highest speed possible for a 73 year old. And by that I mean I ran. It was a very stressful experience.

Wifi wasn't working on one of the UA flights after boarding.

Leg room was lacking. Legs crammed into seat in front.

T hey did a great job. Flight was on time .

the plane was old. the wifi didn’t work. the entertainment was boring and dated. the charging ports were impossible to find. i was mostly ignored by flight attendants that had no problem speaking to the man beside me. i got two drinks the entire time i was on the plane.

The Polaris experience is top notch. From departure lounge to arrival lounge. Everything was top notch. One of the best first class experience

Crew was not very helpful. They forgot to serve me coffee and had to wait for a long time.It looked as if they were not very happy with what they were doing.

EWR terminal C United Club is great. Flight and everything else mediocre

It was awful. For a 37 minute flight time,we had 1:30 hours delay. If someone had a connection flight he or she couldn’t reach for sure. The only positive point was online check in.

Limited snack options cause the snack vendor was on strike

The 6 hour delay with minimal updates was not handled well. After many complaints from most of the un-boarded passengers, food vouchers were offered. The catering strike meant there was no food or snacks on the plane. Beverage service was heavily impacted, only water or juice was available. The staff at the gate was kind enough to inform that "if you want to eat on the plane, you will need to bring it on when boarding".

It was an excellent experience, traveling from Toronto to Denver with United.

Ontime boarding. Almost 1 hour take off delay. We could have boarded slightly later since the pilots were in traffic

I go am isle seat because it was half empty Food strike no food available

Flight was delayed, jeopardizing the following connections. Food was terrible. Crew was great.

This was the first AC flight in a long time that we experienced no delays or frustrations. The gate attendant was extremely polite and accommodating to my husband who has Parkinson’s disease which made boarding extremely stress free. Flight departed ON TIME and was a smooth ride. If only all my AC experiences could be like this.

Great experience on this Air Canada flight. Everyone was polite and respectful, even the passengers are very polite.

My wife and I especially liked the fact that the Toronto agent went beyond expectation to allow my wife and I to sit together. There was no option for us when we booked our seats. Very thankful!

Another 35 min delay landing No apology no communication or acknowledgment about this

Try to humanize onboarding and take AI out. It's embarrassing and useless

no kiosks to check in with- it’s 2024!!! the flight was so hot and uncomfortable - not sure if that’s what caused a lady to faint during the flight but i was absolutely miserable.

Air Canada from Edmonton to Toronto was disappointing but Lufthansa from Toronto to Frankfurt was excellent.

Overall good experience. Polite crew. Good foodandentertainment. Seats are small and bit congested though.

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

The process overall was pretty seamless, and the crew were very friendly (especially Michael). Considering we booked expecting Lufthansa and the flight was operated by United, it was still a very good service and journey overall. The in-flight entertainment was great, with lots of quality options. One slight negative was that I had selected a vegetarian meal prior to flying, but received a vegan one. I think there should be more dietary options as it meant I missed out on some food that I would have preferred (and it seemed like the standard meals and snacks had a vegetarian option anyway). There was also a group of people who were moving around a lot and being generally disruptive at the quietest part of the flight, when the lights were off and most people were sleeping. I would have appreciated staff stepping in to encourage them to be mindful of others). Towards the end of the flight (which was very early in the morning in both time zones), the lights suddenly came on and breakfast was served. In my opinion, this was too early, and everyone was rudely awoken from sleep. After breakfast was cleared away, the lights went off again for about 45 minutes, allowing people to sleep some more. Then the lights came on again for landing. It seems like if they had served breakfast later, the lights on-lights off-lights on shenanigans could have been avoided, and people could have slept longer (and staff could have rested longer too).

You only get a chocolate square and small bottle of water.!

to be bussed around the airport, then have to sit on the plane for an hour whilst the plane was deiced not once, but twice, then to have to wait for a tug driver is unacceptable. The Captain was very good at communicating.
