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.

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

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.

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

Old cabine without flat bed in business for a 12 hour flight is not acceptable

Boarding was smooth and on time. The seat was comfortable and the entertainment worked. Staff were gracious.

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.

worst experience ever i choose my seat in advance and also have my seat selected in my boarding and the they told me that my seat has been changed without notify me

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

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

We transited through Chad and what was supposed to be a 1hr 20 minutes transit time lasted over 4hrs. We didn't get regular updates until we complained. After a 10hr flight from Paris no form of refreshment given and finally arrived Abuja over 6hrs later and none of my bags came

The line at boarding was not well organized and managed

A couple of minor delays in boarding but very professional and efficient staff.

I fly to the USA every 6wks on Ave and 99% of the time I fly Aer Lingus. If I fly BA I’m always disappointed. My only criticism is the food. I’m vegan and over the last year it’s got slightly better these last couple of flights but on the whole it’s not good! Salad and fruit salad for breakfast and that’s also the starter and desert for the lunch/dinner and the main is usually rice with fried veg 😳the pasta is pretty good though. That’s been the last 2 meals…. Everything else is fantastic.

The flight was half full and I presume that the next few days are even less busy not sure why they are still charging a premium to change a flight.

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

Short flight so not much to rate. Surprised I had to pay for a soda.

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Very good need to offer better choice of food for business

Great travel. Wonderful experience. Hope to do it again in the near future. God willing

Aer Lingus doesn't have plug ins for devices at each seat. They also did not give me a dairy free meal as requested and confirmed by staff. It was as if I had not requested anything. Otherwise, they were great!

Decent service - nice seats. Crew were not overly attentive but can’t complain overall for the money

Very nice flight, easy connections in Keflavík, and friendly crew.

I will never fly this airline again. Checking in was poor , we had to go back to the check in counter at Raleigh - Durham international airport three times because they didn’t issue my boarding pass but rather duplicated my husband’s twice which caused a big headache at the passport control at the airport which triggered security alert and wouldn’t let us pass through we we had to wait for long time to be able to explain and clear everything after talking to the supervisor.. No food on the plane , not even crackers. No food was offered to buy ether . No ear phone was provided . Very little time to make from one plane to another and nobody to assist with smooth transition. Flight itself , we felt safe so thank you to the pilots . But customer service was terrible . We spent $ 2500 on 2 tickets, so I cannot say that service was consistent with the price .

Seats are way too much now with these new airplanes especially long flights like we had. I was 7 month pregnant and in a lot of discomfort due to small seats.

Food was horrible. This wasn’t business class. No leg space, can’t sleep in row position, huge delay

I liked how easy my transfers between flights in Keflavik were. I would have appreciated more food options in Keflavik.

The plane was flaming hot! Could not breathe. Everyone coughing from heat. Awful.

My biggest problem was the flight from KEF to DUB was delayed, which caused me to miss my connecting flight in DUB and we were forced into an unplanned 10-hour layover in DUB. Crew and boarding staff were all very friendly but this was a real inconvenience and especially uncomfortable for my disabled wife.

Not much! This was my first flight with Iceland air and unfortunately it wasn’t what I have expected. My luggage is lost nothing as of yet where it was left. Not a good service at all!!

The seat size was more like a domestic than an international flight. In fact, i would compare the ammenities, quality and service to a short hall ryan air flight, which was unexpected for an international flight. The plane was extremely hot so sleeping was difficult. My biggest complaint was that they are very strict on carry on luggage only allowing it to weigh 10kg/22lb. I try to limit myself to a carryon so i don't have to mess with bagage claim, but the wieght restriction made it impossible. I have never had a carry on weight restriction (at least enforced) on an international flight. Will not be including them in future searches.

- OK plane. Basic accommodations. OK food. The digital window shade wasn't working.

- OK plane. Basic accommodations. OK food. The digital window shade wasn't working. - Expect to be woken up more than an hour before landing when they start dinging the bell and making announcements and turning on all cabin lights to serve a snack. I would prefer they remain quiet and only serve people who want to wake up.

Better food and more space in the seats. Also when doing the web check in both times I was going in to your site the minute you open it and there is not really many seats to choose only to buy!!!

It was ok, not as good as it used to be. The Heathrow connection was a disaster - complete anarchy, unknowledgable and skimpy assistance and signage. Gate crew at next flight was great, held the flight while my wife struggled through security.

It was great! The seats were comfortable, and they fed me during the transatlantic flight, something which I have been missing out on for the past 3 years as I travel to and from school.

This flight was cancelled at the last minute. We were rebooked on another flight but a day later. We lost a day of our vacation and paid for a night in a hotel we couldn’t use. The flights we were rebooked on (both American) messed up our seating on both flights-we didn’t get the seats we had paid for. All in all, a terrible experience.

Lost our bags in Heathrow, We didn’t receive bags in Mallorca for 3 days, out of a 7 day cycling vacation. Really inconvenient and disappointing!

We missed the flight to Barcelona because the flight from Baltimore was delayed. We flew on Vueling VW6653. Our luggage didn’t arrive. Please help us get our luggage. We are staying at Hotel Gran Via in Barcelona

The seats were tiny, being of a fairly petite build, I don’t usually expect to feel crammed and cramped in a seat, but I definitely was on this flight. I couldn’t even bend over to get anything out from under the seat in front and getting up to go to the bathroom at night with the seat backs reclined was nearly impossible. I had to do gymnastics to get over and out. For an airline that does long flights overnight, it’s kind of ridiculous.

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.
