I wish Aer Lingus offered free wifi and had power outlets at the seats. Overall, the flight was good. Seat back entertainment had some interesting options. Food and snack options were mediocre at best. I enjoyed the canned red wine.

I wish Aer Lingus offered free wifi and had power outlets at the seats. Overall, the flight was good. Seat back entertainment had some interesting options. Food and snack options were mediocre at best. I enjoyed the canned red wine.

I had an awful experience at the ticketing agent stand. I had purchased three tickets, one of which I had the maiden name of a passenger on the ticket. They refused to help, assist, and actually delayed our process and had us miss an opportunity to purchase a ticket on the same flight. I was sent through multiple phone calls, none of which helped, and the person at the counter was the person who told me to both call Aer Lingus for help and was the person who said they could not fulfill my request that they were privy to from the beginning. My partner is still stuck in Scotland, racking up thousands of dollars in additional fees and tickets. I am very upset and two of my tickets went unused. I will never be using Aer Lingus ever again and I will continue to complain about them.

When I booked the flight, I wasn't aware that this was a "no frills" flight. No wifi, no reclining seat, no complimentary soft drinks.

In business class overhead bins were minuscule. Had to use cabin staff to find a place for my carry-on bag. Boarding process was shambolic, as “passengers who needed assistance in boarding” absorbed an excessive amount of time and attention that Aer Lingus was apparently unprepared for.

Aer Lingus was fabulous.nhowever, Aiirfare Assist who Kayak routes me to to purchase tickets for m was awful. They messed up my reservation so bad that after about six hours on the phone with them over the week before departure, I had been choice but to show up at the airport. The Aer Lingus staff were amazing and got it sorted out but I would recommend not using Airfare Assist.

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.

It was excellent! The plane left Chicago early. Arrived in Dublin early. The crew was excellent! It was a great experience.

Dublin to Boston was decent. Food and entertainment was included and that was expected for the rate paid.

No entertained. food and beverages were not complimentary. they lost my checked luggage which made my 10 day vacation unpleasant.

The food was mediocre, the coffee was terrible. The entertaining selection was plentiful. They lost my checked luggage which put a damper on my 10-day vacation.

The flight was great, due to the impeccable service of the British Airlines staff. This was our first time in Business Class and it was amazing. The flight was delayed over 4 hours due to mechanical issues which is our only complaint of the trip.

Enjoyable flight, helpful crew everything was organized to accommodate passengers.

Worst travel experience ever. One flight missed due to a delay, got rebooked, that one got cancelled and 0 customer service whatsoever. No help for finding our luggage or getting a hotel.

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!!!

I never got the flight. Someone hacked your information and sold me a fake flight. Didn't know this till I tried to check in and was told the flight didn't exsist and it was a fraudulent ticket. I'm not sure how to get this fixed but I had to pay $1500 to book a last minute flight. I understand that this was not Kayak company that sold me a fake flight but I was sold a fake flight based on my booking with Kayak. I ended up having to pay for an extra night hotel stay. I guess I need to start by contacting someone at kayak to get this resolved. My bank has stopped all bank transactions because of it.

They’ve lost my bag and I have no way of really getting in touch with anyone and have received no updates.

the airline check in attendant made me check my carry on bag which was VERY small and contained medicine for both of my parents stating it was a full flight. Upon boarding there were several open seats and available compartments where my bag would have fit. DO NOT SELL tickets inclusive of a carry-on with the intention of REQUIRING people to check it.

Very bad because flight was cancelled and they never informed me i have to wait for three days in hotel to get another flight

Every flight was delayed. They lost our luggage for days.

On time. Clean. Efficient. Just what is required for the short hop.
