Great staff great experience, made a 2 hour delay very bearable

Great staff, great experience, made a 2 hour delay very bearable

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Great crew - old style upper class seats on the older fleet now feels dated

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

Food was excellent. Service was very good. Staff was very helpful to all passengers.

I had zero issues with the flight. I did have issues with the staff at the airport. We missed out flight due to a delay with another airline. Talking to the staff and trying to get a new flight arranged was challenging. One guy was able to try to help us and got us on a new flight, but other staff was dismissive and clearly let us know it wasn’t their problem. All I kept thinking was… this is why air lingus has such a poor customer service reputation. I will be avoiding this airline in the future.

Experience was great overall. However, the connection time between my flights (1hr 15 mins) was too short. We had to get through security check and US immigration in that time, and I made it to the gate just as they were announcing it was about to close. Flights with such a short connection time should maybe not be offered for purchase, or an advance alert would be helpful. Other than that the in-flight experience was excellent, especially the food. Many thanks!

The seats needs to be comfortables, at least please add more padding to the seats.

Incredible service. Incredible entertainment. I felt like they just kept serving us something new avery hour. My wife and I both had a joyous flight.

I liked that I went thru customs in Dublin instead of having to do that in LA.

I was so grateful for the kindness of the crew. They made a long trip very pleasant. Food was delicious. Many movie options

My flight from Dublin was delayed two hours which ment that I missed my connecting flight to Phoenix. American Airlines provided a hotel room and rebooked my flight for 7:30 AM the next day. I didn't get to the room until 11 pm and I had to be at the airport the next day by 5 AM. The airlines did their best but the schedule was challenging for an 81 year old.

Dinner was fabulous. Would have enjoyed a wine with it. None offered... for sale??? Breakfast was disappointing but adequate amount of food.

Dublin airport is big and US Customs and Immigration screening officers are is part of the process there. This eliminates screening upon arrival to US, however should be taken into consideration when playing your transfer. After all, pleasant experience enhanced by draft Guinness and Irish coffee at the buffet area near the gate. We loved boarding by the row, back of the airplane first.

There was a mixup with our tickets. They said they did not receive payment for them but yet we had seat assignments. We had to purchase last-minute tickets which cost us three times as much. that’s why they got a rated of a one.

The boarding process seem to take longer than necessary, resulting in a 20+ minute delay

It was too cold in the plane my feet froze

Handling our luggage was the biggest issue - they lost it and we got it almost 3 days later. Really threw off the beginning of our trip and we really had to change our itinerary accordingly.

Seat was hard and uncomfortable and the temperature too warm and uncomfortable.

No meals included on this long international flight. Most airlines will offer you a meal when flying internationally. Not Icelandair. Your included choices are water and coffee. Poor customer service. The airport was also very confusing.

I flew Icelandair with my partner from Prague to the US. Overall flight time was around 12 hours, with a connecting flight in Iceland. I have flown internationally for years and with multiple airlines. Every airline serves you a meal when traveling internationally. Icelandair not only did not offer an inclusive meal, but they did not even offer a snack. The only things they served over our long flight was water and coffee. Ridiculous! Never again will I fly with Icelandair.

It was good. The air plane is clean and staff were friendly.

Worst airline I’ve ever flown. Delayed 5.5 hrs, missed connecting flight, and missed an entire day of vacation. Zero customer service

Everything sucked. No food, one small glass of water, a tiny coffee, 5.5 hour delay with no customer service. Would never recommend flying them.

There was no lounge at Boston for us to use. Typically flying first class overseas comes with lounge privileges. The seats did not recline even a little. My headset only worked on one side. I felt like I was flying on Ryan Air, not Icelandic Air.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

We left 1.5 hours late therefore missing my connection. The airline didn’t give vouchers.

Food could have something without dairy, I couldn't eat anything. Tv for both seats was malfunctioning. They have one bottle of ginger ale for entire plane.... and I paid extra for these seats...very disappointed

We took two long flights with Lufthansa, both were delayed making us miss our connecting flights. Lufthansa took care of the first one. The second was a switch to United and figuring out how to rebook was not a pleasant experience.

Welp - they boarded us appropriately...then had us sit on the plane for over two hours before cancelling the flight...which meant another night in Munich. I probably had it a little better than most as over 500 people had to be accommodated/re-booked etc. The next day I boarded the same flight (for which I had now been ticketed 3 straight days) and - with "only" an hour delay, managed to finally get home over 2 days later than scheduled. I haven't flown Lufthansa to Europe in years...and I won't be looking to do so again in the future. To be clear, though, the people I interacted with - flight crew, Service Center, check-in were all professional and courteous - management is clearly to blame for their lack of communication and unpreparedness for when things go wrong.

Seat very cramped, could not recline. No cheese with meal. Staff very helpful.

The flight from Dulles to Munich was just okay. The seats were comfortable and extra foot room was noticeable in comfort plus. Disappointed in the booking in so much I requested an aisle seat and then was assigned a middle seat. The food was inedible. Movie choices were moderate. I usually fly Delta, but this WA flight was cheaper. Next time, I'll happily pay the extra to fly Delta.

Food was terrible. They ran out of options and gave me a bland undercooked pasta and veggies. Only middle seat was available to select although I paid extra. Baggage delayed at destination. Flight attendants not really helpful.

One one boarding scanner was working to scan 400+ passengers to an Airbus 380. Food in premium economy was mediocre.

Liked the flight being almost on time (airport issues created a delay). Disliked the issue printing tag bags on the kiosk and having to wait for an hour on like to drop my bags.

There might be more food options for people who can't eat so much starch/sugar/bread/rice. Meat, cheese, walnuts/pecans for snack, maybe jerky or other kinds of meat-based snacks would be better than bread and rice and sweets. I had an extra chardonnay, which was fine. The entertainment was great.

Unfortunately, my flight was cancelled because of some sort of emergency over the Atlantic and had to return to London. While I think British Airways made every effort to mitigate the situation, I must say it was still pretty unpleasant. I do appreciate the fact, however, that British Airways put my safety first…and I think the effort to correct a bad situation was very sincere. But I think the process might be handled better in future.

Crew service was poor and very little difference between premium economy and economy. Disappointed.

My bags never made it on the flight and I now have to wait for them to arrive hopefully tomorrow. You can’t even track your bags in the app to see where they are since they didn’t arrive. You have to file a claim and then wait for them to inform you when you will receive your bag. We were already delayed for an hour due to baggage so I don’t understand how my bag didn’t make the flight.

One of the worst experience given the middle seat even asked for the change no one honored,boarded at the end and overall one of the worst experience

It was good although our flight to the UK was cancelled and rescheduled for two days later. This was after we were already seated on the plane. We missed the first leg of our trip. BA did put us up at a hotel and paid for our meals but we lost our hotel costs in Glasgow.

The crew was very nice and pleasant. We were very reluctant to book our flight with British Airlines because we had bad experience with their flight attendants on the previous trips, they were rude and not helpful.

I am a 25+ years American Airlines member. British Airways is simply above and beyond in every customer satisfaction category.

The seat pads are past there sell by date now and are uncomfotable. Also, with screens in the back of the seat, the seats shouldnt be able to recline as this puts rhe screen in your face.

1. The website didn’t allow me to checkin from London as I have Bangladesh passport with US permanent resident card. This pushed me to sit with my wife in the middle of two aisle seats, terrible experience! 2. BA should allow within 24 hours to checkin with other passport holders to choose better seats. A 2nd verification of travel documents can be done at the desk about immigration status. 3. Food options were poor for vegetarian passengers, try to introduce healthy options avoiding carb-dense food ingredients.
