There was no useful information given regarding the flight back to the UK from Tenerife. This despite the week publicised problems around the EES system and the delays caused to boarding. This aspect of the customer experience could have been much better.

There was no useful information given regarding the flight back to the UK from Tenerife. This despite the week publicised problems around the EES system and the delays caused to boarding. This aspect of the customer experience could have been much better.

Fast boarding, smooth takeoff and landing. plenty of space in seats. Excellent air-conditioning on a hot day. Perfect experience

It was transportation nothing more. I will give a positive rating over Ryanair. We missed our Ryanair flight the night before and received rude and unconcerned treatment from the Ryanair customer service. It was late. We were very tired and stressed after doing our best to get to the airport. The so called customer service ladies were completely unconcerned from the start. Aside from that, the flight to London seemed to be their opportunity for advertising. No time to relax as attendants were constantly in the aisle selling. I will never fly Ryanair again!!

We accidentally purchased twice the bags we needed. Our fault, but the ticket was not clear to us, and it asked us to purchase bags at checkin. When we notified them to get credit back at the airport, they said to contact customer service. We flew the flight and then contracted customer service. They said no credits after the flight has flown. Not customer service oriented at all. They know we didn’t check that many bags and kept our money for a service they did not provide. Be aware and very careful of what you are purchasing from them because they will not make it right if there is an error.

Be sure to check bags for 23 kg,.(50 lbs) Coming from US I chose the wrong size luggage weight when I checked in on my phone, and had to pay more when I dropped it off

The on board air steward really made the journey. He was very entertaining

I was disappointed there was a 40 minute delay to flight

The trip itself was good. I have given only good as rating, because my first flight has been cancelled by a different airline and that caused disruption in my trip. I spent over ten hours in Luton airport and that caused me high tiredness, sickness, because of the very early initial trip. easyJet staff has been professional and friendly.

3 hours delayed Don’t understand why when you have paid for ‘speedy boarding’ they call you forward to then make you stand fir another 20 minutes in a confined space before boarding the plane.

Delayed and ketone runway. Was told some nonsense about thunderstorms slowing down flights. Why not just come out and tell customers NATO and BRITISH FORCES were doing defence exercises and were in control of AIR SPACE.

I purchased premier economy seats but I was seated one row off and was sitting in economy my bottle of water and cookie did not compare to the menus handed OP it in premier.

The plane was a long way from departure lounge. The plane looked tired but got us there.

No problems except for a completely full flight. But we were add one because of a previous delayed flight.

Cramped seating but standard in all smaller aircrafts today no matter what airlines. Crew very helpful, friendly & attentive so makes up for that.

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

Ohooo it's fantastic 👏 I love it 😀 😍 ❤️ it's on time ⏲️

First time on BA but will fly with them from now on! Everything about the flight was superb!!!

The flight was very delayed in taking off - which was out of control of the crew, but then the pilot worked hard so we only arrived about 30 minutes late. Everyone was very friendly and accommodating!

Only for BA because we had to get to Edinburgh at a certain time. Baggage lost, late boarding with only one person checking, again, our passports and boarding passes until the despatch controller had to step in to get us away. Will never fly BA again.

Flight was canceled with little notice or explanation. There were no other flights to Belfast from Heathrow, so I had to travel across town to London City (or wait until the next day).

Flight delayed but lack on information at the airport - only knew from looking at flight radar Other people queuing ages before a plane was there as staff not informing them of delays Usual issues with boarding people haphazard What is the point of priority when they don’t stick to it and all held like cattle just before getting on plane

The flight was on time, great value and very helpful crew. This direct flight was the most convenient I ever had coming to Sarajevo over the years. Will definitely use this flight again in the future without hesitation.

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

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.

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

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.

I were there 20min before departure and they didn’t let me on the board with 5 other people, after all they admitted it was their(Ryanair) fault.
