Heathrow seems to have a lot of plane traffic so make sure you have a good cushion of time if you have connecting flights. I had a 2 hour layover but ended up having to run to make sure I got to the other gate in time.

Like getting a bus. No great luxury but will get you there

Got us to destination alive, albeit a bit late. Luggage was left behind. No live tracking app available (available on some other airlines). Supposedly going to be delivered in next couple of days.

The trip was mostly nice, till the last moment when they had some issue with opening the flight door. The flight arrived late by 10 minutes, which was ok-ish, but then we got stuck on the plane for 35 minutes at the bridge and that costed our connection flight to LAX which left with 12+ passengers still on our flight. It added 2 days to our trip home, and we had to make lots of rearrangements to deal with the ripple effects. Don't book a 1+ stop trip with a layover time less than 2 hours.

My seat was broken. No sound available and the armrest between my wife and I was broken so it could only fold halfway up. Seats were a big close together so they felt a bit claustrophobic. Boarding was a little frustrating in Dublin as there is not sufficient room to actually queue up. Boarding was also frustrating for people behind me who were unable to use the overhead due to people abusing the privilege and putting more than one item each up there. Staff was friendly and helpful to those people.

The staff was amazing, so friendly and responsive. Check in was tedious as the online service was not available and the desk understaffed. It took a full hour in line to check in. The seats, in economy, where quite spacious until the people in front of us reclined their seats which then meant the seat was touching our knees. The inconsiderate people who were seated in a bulkhead kept their seats reclined for 80% of the flight and then got annoyed when we bumped their seats while shifting positions. It was highly unpleasant..

The connection time between the regional flight (from Newcastle) to an international flight (to The States) was too short. To require as second security scan and customs clearance within an hour and 20 mins is not enough time to make the actual connection. We had a final boarding call the minute we walked out of US customs and had to sprint (with two small children) through 20 gates to make it in time before the door closed. The concept is great in theory to clear customs before leaving Europe, but the timing needs to be adjusted. We travel abroad frequently and won’t be using this route again. Thanks.

Canceled my flight couple hours before takeoff. They could not find a decent re-routing and refused to pay for when i subjected alternative with Lufthansa.

Seats a little to soft on the SFO DUB flight

I was not admitted to the flight!!! I need a refund for this

Well, I think we left close to on time. Crew was “eh”.

Great flight just took some time to board even when lining up early for the flight, even taking off took longer then expected.

Take off was great but landing is always with a bump.

Staff were very professional. Much better than the outgoing flight from Dublin. Seat cushions were practically non existent. Making for a very uncomfortable flight.

Flight was delayed by 1 hour 45 minutes. Aircraft was cramped, dirty and uncomfortable. Boarding staff more interested in charging you for oversize baggage than getting you on board. Overall not a pleasant experience.

They were extremely unprofessional and unhelpful at check in. They did not understand laws related to Spanish residents flying with family It was very discriminatory the way we were treated.

A delay of almost 3 hours. It was evident that the staff wanted us to board urgently, to the point of rudeness, to avoid paying compensation

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

On time arrival but the aircraft had seen better days and needed a deep clean.

It was appalling, full of young people who were drunk and disobeying instructions to sit down. Crew did nothing to enforce. There was a Ryanair pilot sitting in the aisle opposite me who talked through out the safety briefing so loudly I couldn’t hear. Whole thing felt unsafe

Delayed for 2 hours lack of communication no refreshments as promised and the drinks on board were not as ordered and refused to refund

I was unable to board this flight because of visa changes that I was not alerted about and I’ve been unable to contact Kayak to obtain a refund / credit anything.

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort

Check-in experience, for business call please provide a premium experience

Lost my luggage, ran out of food choices in business class, ground crew was completely unapologetic.

Excellent. The crew and flight were great. Checking in was easy and everyone was very helpful.

Late. And service was very slow - passengers sat for well over an hour with dirty trays etc surrounding them

Entertainment devices on A380 need to be fixed, the seats might do with updates.

I like everything about British Airways. Excellence. Perfect. Exquisite service.

The plane was dirty the food was awful and the boarding process took too long

Very late to leave, poor communication on expected departure time and when boarding actually started.

Everything was perfectly fine, it’s exactly what you would hope for from a budget airline. You get what it says on the tin, what more could you ask for?

Cheap flight but I didn't like the almost one hour delay because of paperwork!!!!

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.
