The food from Lagos to Amsterdam was was very poor compared to AMS-YYZ

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Seats are fair enough for medium tall people. Good food all the trip. Fight attendances are warm

The food was ok. The crew seemed like they were cranky. I had one guy get mad at me for passing in between the storage area to get to the other toilet. I can understand if it's not allowed but reprimanding me like I'm a student saying "This is the last time!" was not appropriate. During my meal time, there was a French family around me. No problems there but when we usually have meals, they are supposed to put their chair in the upright position. These people did not do it and the steward did not tell them to raise their seat in the upright position. However, I was told to do so! So, me and another person next to me had to eat with the monitor almost touching our faces. Furthermore, a lady in front of me was putting her feet up and preventing another elder passenger from putting her seat back. To make it worse, she was continuously hitting her back into her seat, shaking my monitor while I was watching a movie. A crew member did speak to her about it but then she accused me of pushing her seat forward! The crew member gave me a death stare and told me to stop pushing the seat forward. I did not even touch her seat at all, if I did, she would know it. Her boyfriend also stood up and tried to push her seat even further past the maximum decline to no avail. None of these people were reprimanded but the steward, some bald guy, was extremely friendly with them and did not even try to instruct them to do anything until it was time to land. I resisted the urge to really argue with them because I would have obviously been seen as the aggressor (I have no idea why). I hardly said anything on this flight except "more wine please" and "sorry" if I bumped into someone accidentally. Overall, it was an annoying flight and I had to resist the urge to yell at the steward and the people he was overly friendly with. The happiest moment of this flight was leaving it.

One of the vstewardeses wanted to bump me of the plane for absolutely nothing. There is CCTV in the plane ans everything can be verified. Very disappointing , you all will see, o other 5 years and the passangers who does not smile to flight attendent will be bumped off...

I travel frequently. The flight was late again... KLM should really try and be on time

The flight itself it was great nice food the crew were very nice and helpful, Checking in from Birmingham wasn't great long queues for bag dropped, And I had my hand luggage case taken away from me even though I requested to have it with me as I had breakables items. I was told I can not because of the length of the flight with no explanation at all no options was given for me to take my fragile items out of my case it was taken away with hold buggage I find the staff member who was checking me in very unpleasant !! Can we please be advise if the rules have changed about the the carry on hand luggage it will be easier to be advise on booking your tickect if we not allowed to take the hand luggage with me. Overall I had a good flight .

The food quality is poor. The staff are very friendly and accommodating. The entertainment program was limited. I experienced a delay of 30 minutes due to two issues. Passenger luggage had to be removed and there was a technical issue with the stairs not detaching from the aircraft. The pilot managed to compensate and we arrived only 15 minutes later. The luggage at Dubai airport was very slow. I waited over an hour.

I requested wheel chair assistance , it was confirmed via email that inwoood get it but I didn’t get it . The last leg of my trip to Nigeria was the worst.

The boarding was one of the worst I’ve ever experienced. The fault lays on Ohare Airport and not so much the airline. The waiting area by the gate was the size to accommodate a regional flight for 20-30 people and right next to a busy walkway. When you cramped nearly 300 passengers into that space is was unbearable.

Great flight- smooth, nice crew, nice clean aircraft, departed a little late but arrived 10 early.

It was listed on my ticket as Finnair but there was no indication that the flight was Finnair. In fact the number was even different. There were no employees there until exactly 2 hours before so we had to wait in line at Iberia and hope

Sorting on line would have been appreciated Onward information on flights missed No ability to get seating arranged before we got to gate Very unfriendly at gate

The flight was Finnair but there was no indications anywhere that the checkin was for Finnair also. There was no one to ask. I think at a minimum they should list the code shares so people don’t stand in the wrong line for an hour.

I booked the flight with Finnair, which made the arrangements for downloading a boarding pass unnecessarily complicated. I wouldn't do that again. Instead I'd book direct with AA.

Flight ok, but me and other two passengers didn’t have connection with the entertainment in our seats. So, no movies, no games, no music… for 9 hours. The crew just told us that there’s nothing they can do but I noticed during the flight that there were empty seats, so they could have offered to us to change seats. Customer service could be better.

Finnair cancelled my flight 12 hours prior to leaving for Helsinki. They stated there were mechanical problems. I had to scurry around to find a new flight that would meet my needs for arrival in Helsinki. Luckily I was able to find alternate transportation through Lufthansa/United.

I’m very disappointed, to fly into an airplane for 10 straight hours, and not having a TV even though when I put the ticket I was told that I will have entertainment for the TV. Very disappointed.

Helpful steward. Allowed me to move to some empty seats and I was able to get some sleep. He also had milk for my tea. Americans don’t realise that cream or half and half ruin tea.

Security was a mess at the Helsinki Airport. But I was delighted by the connecting flight waiting for us for JFK.

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.

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

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

Hi vergin Atlantic service was good but the flight ticket agent travel up charge me extra 57 pounds as a airport charges, actually I refuse to pay but they say if I not pay £57 then they say you will not be able to travel from Heathrow to goa ,so for me there was no option and it was just 3 day before my departure so i paid, so please look in to the matter. And I have a receipt of £ 57 as well .thanks

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 meeting was fantastic. Breakfast needs a lot of work and food was overcooked and not very nice for breakfast.

We originally had a window seat. Our seats were changed to the center isle between 2 bathrooms. This was a red eye flight and we were traveling with an infant. Due to the light from the bathroom doors opening and closing throughout the night our infant would not sleep and cried the whole night which kept us awake and everyone around us. It was a very unpleasant experience for everyone trying to sleep.

Tai-City to Atlanta :Lots of legroom on the flight. No interaction from the staff at all on the plane. They only attended to the First Class passengers. There was no entertainment. Security I was body scanned even though I hadn't set off an alarm, my father-in-law in his 80s, was stopped and subjected to a through body search, told that they would have to place their hands in intimate places. There were several border guards present, and as we walked off we could hear the TWA officer talk about the procedure as if he was training. My father-in-law was a little upset about the whole process. A kind explanation that training was taking place would have been more acceptable, and it felt dehumanizing to him. Atlanta to London: Check in was difficult we had been unable to do this online for 2 of the family members on the same booking both in their mid to late-80s. No seats had been allocated for them and we were all travelling Premium Economy. After several phone calls to the booking agent and conversations with Delta staff at TriCites airport, we were told that seats would be allocated at the gate in Atlanta. When we arrived at Atlanta, and spoke to a member of the boarding staff at the gate, he was curt and repeated back exactly what we had just told him, that only one of us was checked in. I explained that we had been unable to check-in online for the 2 family members (I had tried twice). He again repeated back that we needed to check-in. As we were in transit, I was at a loss at what he wanted us to do, but he kept repeating that we needed to do this. I asked where we should do this. No answer. In fact all he did throughout was look at his screen. He told us that there were no seats in Premium Economy, and that he could offer my parents-in-law 'two seats at the back'. I asked if he meant at the back of Premium Economy, and he replied, 'No, at the back of the plane'. At this point, myself and my father-in-law pointed out that they had paid for Premium Economy tickets and expected seats there. He never took his eyes off the screen once. Then he hit a button and it printed out two boarding passes for my parents-in-law. The seats were directly across from my seat. He had gone from saying there were no seats to somehow finding two together. No explanation, no eye contact, nothing. The flight: As we boarded, our first introduction to the flight was the stewardess at the entrance addressing a passenger with an annoyed and loud voice about a bag that belonged to them. That was not promising. The seats were good, and so were all the accessories. The food, etc.: we had flown with Virgin on our outward journey and I could not fault it. The service and food was excellent, the stewards very helpful, offering additional drinks and snacks. The toilets were more accessible than Delta, which were in the economy area and were told in no uncertain terms that we should not use the First Class toilets, even though they were much closer to our section of the plane. We had a menu for both flights, yet when I asked for the chicken dish on Delta, I was told that there was none left and that there was another chicken dish with mashed potatoes and that 'it was fine'. This was almost pushed on me before I could answer. I was sitting 3 rows from the front of the section, so I was surprised that they had already run out. I repeated that I would like the chicken dish on the menu, and asked whether she would be able to get one from her colleague who was serving in the other aisle. The stewardess replied 'No, that's not how it works!' It always has on previous flights, so I was a bit confused. I accepted that I would have to opt for the pasta option (no choice), but was a little perturbed by her response. Minutes later she returns and hands me the chicken dish I had originally asked for. I had already started eating the other one, but was told curtly that I could have both. This was the same stewardess who was shouting at a passenger as we boarded the plane. The food was very poor in the end, nowhere near as good as Virgin's. Unlike Virgin, there was no starter, no bread roll, just a main and a brownie served in a cardboard container. Virgin had provided real china and glass. Unlike Virgin, they did not return to ask if we wanted more drinks, and there was no tea or coffee served after the meal. The breakfast that was served later was equally poor and inedible, apart from the fruit. At the time, the stewardess, a different one, completely walked past my mother-in-law and did not offer her a hot drink. Both my parents-in-law are in their mid to late 80s, they have been world travellers in their time and had decided that this would be the last flight that they ever take. They have health problems, including memory issues. I feel that overall the journey back to London was pretty unpleasant for them especially, and that they were treated badly, especially by the ground staff. We have lived on two continents and are used to long haul flights, and I have to say that this is up there in the worst flight category. Bearing in mind that we had paid extra money expecting comfort and additional attention, it was extremely disappointing. I would fly Virgin again, but never Delta. The two flights were incomparable.

Lots of legroom on the flight. No interaction from the staff at all on the plane. They only attended to the First Class passengers. There was no entertainment. Security I was body scanned even though I hadn't set off an alarm, my father-in-law in his 80s, was stopped and subjected to a through body search, told that they would have to place their hands in intimate places. There were several border guards present, and as we walked off we could hear the TWA officer talk about the procedure as if he was training. My father-in-law was a little upset about the whole process. A kind explanation would have been more acceptable, and it felt dehumanizing to him.

So Iceland Air is one step above Spirit Airlines. They do not feed you unless you pay for it or are in Saga Class. So, bring your food. They have a drink service, but it's in a large Dixie cup. Ask for the can, that is the only way you'll get a real drink. Also, we missed our connecting flight so they put us up in a flea-bag motel. Don't get me wrong, the staff was nice and friendly, however, there was no shower gel or shampoo in the hotel. We have to go to the corner store to pick some up. The room was not in great shape. Holes in the bathroom, a badly repaired ceiling in the room. The window was warn out. So, you get the just of how bad it was.

Paying $75 for my bag is disgusting. Got off ground late so I missed my connections. Kept us waiting for passengers in the cold. Will not use them again.

Food and staff were excellent. Seats on Saga (business class) are comparable to domestic first class of US Airlines, regarding space and recline. Entertainment options had little international component.

Flight delayed Delay to the gate upon arrival Baggage took more than an hour so we missed our connecting!!! Terrible experience!

There is no food without paying $. Only soft drinks are included in your fare.

Some drinks and basic snack will be good. Water should be served at least once an hour. Blankets for folks who might be cold.

Pros: "Flight was relatively empty. Professional crew, comfortable seats"
Cons: "I think they skipped me with food service. Checking up on passengers who may have been sleeping would be nice. Headphones need to be purchased. Limited entertainment options."
Cons: "Communication about international COVID requirements before the day of departure."
Pros: "My seat cushion was out of alignment so not great. But I like the two side seat configuration."
Cons: "Boarding is a zoo. Board by row. It’s faster."
Pros: "Icelandair crew were very hospitable and accompodating"
Cons: "I have never sat in such a narrow seat. Literally could not put my hand down the side to pull out my seat belt. Two days later I still have sores from where the side of the seats hit my hips. Did not even provide complimentary peanuts."

The crew was very attentive and kept busy serving a variety of treats!

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.

Not enough trash pickups throughout the flight. Everything else was great.

Overall good, the gluten free food is very hit/miss though and you must tell them you have an allergy days in advance.

All was good. The headphones they supply are of poor quality. The food is good but too much dairy.

Seating space was crowded and I am a very small woman.

I sat in the last row of seats. On an 8 hour flight they allowed folks to stand and talk and drink in the back area near the toilets the whole time. They were at times loud and in the way. It was a little annoying. The crew on this trip were pretty mediocre and the plane was littered with trash when we disembarked.
