The flight was again delayed for more then 2 hours with some lousy explanation regarding the reason of the delay. Although the flight was delayed for more than 2 hours, no refreshments were offered (according to EU regulations). Last 4 flights on KLM - always at least 2 hrs late. So be prepared that you cannot plan anything with KLM.

The flight was again delayed for more then 2 hours with some lousy explanation regarding the reason of the delay. Although the flight was delayed for more than 2 hours, no refreshments were offered (according to EU regulations). Last 4 flights on KLM - always at least 2 hrs late. So be prepared that you cannot plan anything with KLM.

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.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

Overall a good experience. We were disappointed when we had to check our carry on due to the plane being full. KLM hadn’t notified us and we had valuable items in the carry on but they still made us check it. Some of the food was great and some was mediocre. Crew is really kind and funny.

Mostly fine. Minor delays departing and arriving. Quite a cramped plane, not so much as regards legroom but very narrow seats. Quiet nice food. Non-working USB charger. Flight attendants were helpful but not particularly proactive — one had to work to get their attention (but all was fine once they notice you), very Dutch style:)

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 .

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.

Well, in my case; the flight was delayed 1 hour, we have to wait in the plane to get green light. And the plane (probably because was a short trip) did not have entertainment or WiFi. No a good experience.

one of my bags was drenched with fish smelling water and all my new clothes bought at dublin and the 23kg checked in bag were all gone waste with very pungent fish smell and also having stains

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.

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

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

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 for a fantastic friendly nice we came round and check we need anything else to eat or drink

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.

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.

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

They should. Heck planes more often not when they are suppose to be leaving causing delays

Thankfully not a full flight so although my headphone jack wasn’t working 100% on my window seat, I was able to move to the aisle seat. Food was fine, nothing great but tasty enough. Crew were friendly and made enough rounds. Always have a decent experience with Aer Lingus

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Great hospitality and service! Seats are better cushioned then some

Great hospitality and service! Seats could always be cushioned better.

Customs is always a challenge. The customs officials were real humans, which was nice-not robots programmed on angry 😊. If you’re in a hurry to get through you’ll be stressed out. Allow yourselves plenty of time and it will be a stress free experience.

I got rerouted to another flight/city because the original flight was late and I would not have made my connection. I had to wait an additional five hours (no compensation) for the new flight which was also delayed because the computer was not working. Arrived at my final destination after nearly 20 hours of travel only to discover that my baggage had not arrived with me. Two days later and still waiting for my baggage. Customer service has been incredibly unhelpful and even hung up on me because I dared to ask for them to have someone call me when my bag arrived at the airport. No one apologized to me for what I experienced and they were dismissive of the fact that I have absolutely no clothes or toiletries. Absolutely awful, disorganized and stressful experience. Am dreading the return flight.
