This flight was delayed and caused me to miss my connecting flight from New York to Boston. I had to rent a car and drive myself home to avoid waiting another 5 hours in the airport.

There was a very drunk and disruptive passenger who was on the plane, right behind me. He was already drunk before boarding but was still let on the plane. He kept kicking and hitting the back of my chair the entire flight. It was an early morning flight and had zero rest on that leg

Really lovely trip and flight. The flight staff were so accommodating and warm throughout!

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Very sad, couldn't stop crying. Was an hour delay in Ireland and when we got to Canada the flight was boarded and couldn't get on. Was the last flight of the day. Now in a hotel waiting on a stand by.I have to got o work, so I'll go first available while my son stays in the hotel til one's available

Was not aware that Aer Lingus was like the cut-rate services in the states, with no food or beverage (other then 3.50 Euro coffee) and no screens for entertainment. Was a great flight, but not much in the way of services.

during a very rough flight, I was forced to sit in a last row seat, fell asleep, and was forced to return to my assigned seat after the turbulence. The stewardess then used that seat to sleep.

I didn’t realize Aer Lingus was a “nickel and dime” kind of airline where you had to separately buy all the amenities you wanted. The push to purchase duty-free beauty products was off-putting. And our row had the least amount of leg room I’ve ever dealt with on a flight.

We couldn't talk to aer lingus we had issues with the flight change and aer lingus made us talk to kayak

Very pleasant staff, there was some turbulence but the captain was very apologetic and gave notice where possible.

Courteous and warm. Good experience while traveling back with an infant.

Missed food service or not enough food available to serve the passengers. Very poor leg room in economy. Uncomfortable and old seats with some of the seat covers coming off. Lights, entertainment system and call buttons not working for an entire section of the flight between Del-Lhr. Very poor experience overall.

Boarding in Dallas was hell with extremely rude gate agents , especially a lady named Rajathi who was the epitome of rudeness with no compassion at all . She was horrible and I wonder why airlines have people like her on their roster who exude arrogance and haughtiness . Will probably not fly British Airwsys because of people like her .

It was just ok. Half the bathrooms were broke on the flight.

Was very bad the cancel the flight after when we arrived to London

1. Missed to deliver bags at Destination 2. no coordination at Layover for flight connection for wheel chair , could have missed flights 3. Customer service agents are not honest , talk with attitude and do not provide correct information about baggage policy

Denied boarding passes for connecting flight. Missed connection as a result. Customer services T5 Heathrow airport vile, arrogant people who lied to us and threatened us.

Much better than from Singapore to London, which was awful. London to ORD was business class experience expected. Friendly and helpful flight attendants, decent main course, delicious dessert, comfortable lay flat private seats.

The flight was severely delayed. The check in desk was rude.

Everything worked well. But nothing really stood out. BA is a reliable work horse for international travel. Moderately priced, reliable but not outstanding in any aspect. I will definitely use them again. The morning flights out of India a definite blessing.
