The check in and boarding process was smooth, and the flight was fine.

The free WiFi was great so I could stream movies during the flight. I would like to have movies available instead of on my device. Thanks!

We had a wonderful experience with Aer Lingus. The seats were too close for the long trip. The crew was absolutely perfect. They were so caring and thoughtful! My husband did not have a good experience with Air Lingus on the phone when trying to take care of getting better seating because he is disabled and needed a wheelchair prior to the day of our flight! Mariam R. in Boston was so helpful with seating and getting help for my husband. Filip Pytka who works for OCS was extremely helpful! He made sure that we had the lift because my husband could not climb the stairs to get onto the airplane. He took us from the gate all the way down to where we needed to be.

Excellent flight and crew. Boarding at Dublin Airport was a very difficult trying to find the right gate.

Delightful flight, ahead of time with a super crew, thanks

I had a great experience. I wasn’t sure what to expect but the crew helped me check my bags and made sure I got in the correct line to board. It was a bit of a walk to my gate so arrive early. I would recommend securing a flight that includes checking in your bag if you remotely think your baggage is over 10kg/22lbs. Be safe and upgrade unless you are carrying a backpack or weekend type baggage.

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!

Pretty darn good. Food was typical airline food. Not anyone’s favorite.

The family sitting beside me had a one year old constantly crying and another kid kicking my chair. I understand it’s nothing the airlines could do or it’s fault

The seating area was small and uncomfortable. The person in front of me put her seat back and my area got even smaller!!

The flight was cancelled, so why are you asking me how the flight was?

It would have been nice if my luggage had made it onto my connecting flight as well. Now I have to wait for my luggage to be delivered and that might take a while, which certainly put a damper on the entire experience.

Biggest gripes were that the seats were extra narrow as the 4-in-the-middle taper down. As with most flight, too little leg room hurts my aging hips. Also changing the flight time to 3 hours earlier meant that we had a terribly long lay-over in one of the world's most boring airports

German crew were very kind. Food was okay but can be better, especially bread was not good, Garbage collection was very poor.

Great! Great staff, great food, great flight :) Keep up the good work!!!

It was good. Nice entertainment selection to keep me busy for the timeframe I wasn't sleeping. Professional, courteous and attentive crew.

They lost my bags and I didn't get them for 4 days after. This also happened to about 30 other people on my flight from fra to MAA (I know bc we were all filing claims in line together from the same flight.)

Flight took off arrive Frankfurt fine ... and then the Pilot parked the plane for 20 minutes while waiting for a steps vehicle to arrive so we all could deplane. This caused us to miss our Naples flight by 6 minutes while running to the next gate.. We are aware of 3 others who also miss their flight. Lufthansa Support said "why miss your flight, your flight arrived on time?" We explained, they provided another flight many hrs later, no meal voucher because our "flight was ontime".

They help we received from the check in crew and boarding cr

Both flights were on time. Great selection of movies on board. My luggage didn't get lost, which made my trip very easy.

Meh. Lived the seat. The entertainment unit did not work and had to be reset 3 times. Service was SLOW taking over 90 min to be served. Crew forgot about my meal. Chicken was dry and almost inedible.

Flying on the Boeing 787 from Seattle to London was everything that I expected. Every thing was great.

Moved me away from my family and refused to fix it.

Connection at Hethrow was horrible..We couldn't get out of the plane for an hour as they were buying people to the airport and there were not enough busses. We had 2 and half hf between flights so it was very tight. After departing plane we had to go thru security again. People with less time in between connections missed their flights

There was a slight delay. Otherwise, everything else was satisfactory.

Captain sick. Unable to get replacement so delayed me 30 hours, many others delayed 54 hours. TOTALLY DESTROYED ALL MY PLANS, including lost my rental car which would now cost over 5 times what I paid so stuck with buses n trains... lost hotel reservations.... HORRIBLE!!!

The BA business class cabin is excellent,very comfortable for sleeping but the service could be improved.

The flight from Seattle was delayed, which made me miss my connection to Florence. I was re-booked NINE HOURS LATER!!! That’s basically a vacation day lost. British Airways needs to partner with other airlines when possible to get a more realistic travel time, if delays occur. I realize there aren’t many flights to Florence from London, so I would book differently were I to return. The actual flight from Seattle was very comfortable and the crew was great, no faults there. I enjoy British Airways, this was an anomaly.

Could have done with a 2nd round of drinks even if it was only to distribute bottled water

The second leg of my flight unexpectedly got canceled. I was stuck at the airport for the whole day and instead of flying out that morning I flew out in the evening. For some of my fellow passengers it was the second cancellation and their original flight was supposed to go out the day before. There was no reason given though getting rebooked was quick even though I would have preferred if I would have been on one of the earlier flights that day. Compensation was a £10 voucher for some food at the airport. I eventually arrived without further incident but but due to the cancellation, it was one of my more frustrating travels of my life.
