Gate agents kind of serious. Had to wait til arriving at gate to choose seats. Thankfully they did give us seats together! And grateful the honored our age, giving us seats at the front.

Very polite and helpful staff. Jet blue…ok, but not as helpful!..

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.

Flight was great (only a short hop from London to Dublin). Wi-Fi available on board(around 2 euros), power sockets, complimentary water and biscuit. Landin/ takeoff all went without a flaw.

I was charged fees for check in bags at the airport by British Airways. It was supposed to be no charge but Kayak messed up my booking apparently and I had to pay for check in bags. I paid $175.

Good crew and on time but old plane and poor breakfast

The worst travel experience of my life. Boarding chaos, delays and disorganisation at every stage. The worst of many was sitting in freezing temperatures for 10 hours whilst asking all cabin crew to turn the heat up to no avail.

They took my carry on and checked it in. Staff in general at Heathrow are not friendly or helpful

There was no legroom whatsoever to the point where my wife dropped her phone and was unable to retrieve it as she couldn’t move. The sound system for the entertainment had a broken socket so was effectively out of action as it just crackled. Just dreadful, I will actively avoid BA in the future

Gate closed way too early - over 1 hour before departure. Put onto next flight. Ticket had been changed without notifying us.

British Airways provided prompt service and maintained excellent cleanliness throughout the flight. However, the business class seats felt tight, and the cabin temperature was uncomfortably warm, making it difficult to sleep. Since I couldn’t rest, I turned to the in-flight entertainment, but the selection was heavily focused on Paramount content, which isn’t my preference. I also found the Bollywood movie options quite limited compared to other airlines. On the positive side, the spirits selection was impressive, and the staff was exceptionally friendly and attentive.

I like Cityflyer as a semi-stand alone part of BA but I dislike mainstream BA thoroughly. A budget airline with budget service but with normal flag carrier prices.

I liked having access to all the Harry Potter movies and the food was good. The staff was also excellent. The pillows and blankets could’ve been better as mine had stains when I arrived

Gate is far at Leeds Bradford Airport. However, as the flight was less than half full, it was calm and not stressful. Great take off and landing. Friendly staff

Boarding was started early and we were lined up in. A glass tunnel on the tarmac we were left standing there for an hour with no information the flight left and arrived 30 mins late

It was great. We arrived a few minutes late but the crew were concert and kind about it. It was a nice smooth fly thanks be to Jesus. I prayed for smooth flight and Yahuwah answered my prayer.

Need more check in desks at Marrakech. Even if you are travelling with hand luggage only, you still need to 'check in' to get the old style boarding pass. Unfortunately they haven't thought to separate out the people checking in luggage to a separate desk. Flight was delayed leaving but arrived on time. Limited food options on board and very overpriced.

We bought tickets for £30 from kayak but we paid £55 for check in to rayan , they slaught us

Flight was delayed so long we missed our second flight. Entire trip had to be cancelled. Ryanair refused to help us.

Stanton airport is outdated, pure equiped, airport. Fire alarms, power outages is a common routine, wich result ir flights delay , additional money spending and huge gathering of people in airport wich is unsafe.

After you made us check-in I tried to add a suitcase in the internet and also to get help by chet. Nothing work and we pay 60 pounds at Airport. Comper to Easyjet to do the same, was easy and customer friendly.

Boarding was like being hoarded like cattle, all penned in in an area way to small

I missed the flight from Manchester to Dublin because of poor informations from Aer Lingus and the airport, no possibility to check in online, they don't respond to phone calls, I had to buy another tickets to enable me travel to Dublin from Manchester. I want my money to refund.
