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

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

The baggage wasnt uploaded to the plane, lost baggage handling is very poor.

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

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.

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

There isn’t any entertainment. The food and drink was available for a price. I didn’t buy any.

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

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

The plane was late (as was my flight out from Birmingham the day before)

The flight was delayed by an hour. Made the connection uncomfortably tight.

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

I have flown with many airlines. My first time was several years ago. Now I remember why I avoided them for so long. Lufthanza is the only airline who has ever raised a size/weight issue with my modest standard size carry on. I had to repack three times to meet their carry-on weight criteria. (Apparently the rules of physics apply differently on Lufthansa flight than on other airlines.) In the meantime their staff was quite rude, repeating meaningless phrases like "Rules are Rules." And ignoring the additional fact that weight is also weight, whether it is in found in your carry on or in your suitcase. They eventually acknowledged that customer service and satisfaction is, for them, a low priority. Never choosing Lufthansa again.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

I barely made the flight. We had to take a bus to the plane and the plane smelled awfully of body odor. When the flight attendant walked by she smelled of body odor. It was incredibly uncomfortable. Also my luggage did not make it onto this flight and when it finally arrived home the handle of the luggage was all ripped. I will have to purchase a bag again.

No food just water No entertainment possibilities. No jacks to charge phone or anything

Typical wizzair flight, nothing special , but as there were flight in the evening we got sandwiches with 50% discount. Terminal wizzair is using is awful. Separate from normal airport, no duty free and only one cafe. Also was late for more than 2 hours but we didn’t got any food or water vouchers.

Timely departures and arrivals. The seat was slightly forward leaning which made it uncomfortable

Flight was delayed by two hours and we then sat on the runway for another 40 minutes and circled Gatwick twice making it 3 hours later landing this is very poor compared to all the other operators I’ve flown with the outbound flight was an hour late

There were not enough staff and signage to direct people to Wizz Priority lanes for check-in and boarding. It didn't feel like we were Wizz Priority holders.

Had to pay £45 to check in at the airport because I didn't check-in online at least 3 hours prior... and it wasn't mentioned on the booking / App (online check-in is only marked as "included service"). Upon landing, captain failed to land the first attempt and had to take off again for an re-attempt. Overall mid experience, would definitely pay a bit more at first to avoid this again.

Two of our boarding details were missing and they wanted to charge us 84 pounds for that, although it was totally their fault

They boarded us despite knowing we wouldn’t be taking off for another hour and boarded us into a plane who’s air conditioning was not working properly. So we were sat in a hot plane for an hour with no access to the bathroom getting hotter and hotter. A little bit of communication between the teams would have avoided this.

I planned to be working during the flight but next to and in front of me there was a family (basically all around me) who had screaming kids all the way long and they were rude and the kid was kicking me as well and constantly wanted to grab my phone etc. I was so pissed, I didn't think they will travel priority so I didn't think they'll sit next to me but they did. I asked the crew if there is a chance for me to go to another seat far away from there...And they were so kind, immediately after take off they showed a seat for me that is far away from these people. I'm so grateful for this!!! I hate that I cannot figure out these things in advance. I WOULD BE HAPPY TO PAY MORE IN ADVANCE TO MAKE SURE THERE ARE NO FAMILIES W KIDS AROUND ME!!!!

Brand new aircraft Airbus 321neo, good seats although no recline (so no arguments with other passengers). Orderly boarding using front and rear aircraft doors for efficiency. Departed on time and artived 25min early. During check in, ground staff are very strict about permitted baggage and carry-on weight and size - you're only allowed what you paid for. Onboard food and beverage prices are a bit high but similar to airport coffee shops.

Boarding was fine, crew professional but not very friendly. Seats are very tight & uncomfortable. 1h delay due to crew change and mechanical issues - no communication whats going on.

Even when you get the priority pass the experience is not what it meant to be priority

I wasn't able to check in before because I had no internet on a long ride over and I had to pay Euro 50 all together I paid an extra Euro 200 on top of the original flight because I had suitcase and carry on and I wasn't able to check in online before And the end it ends up being more expensive flight than a regular carrier You don't save money and the plane is less comfortable

Surprisingly, a very good flight. No wonder that Wizz flights are always full.

Boarding from Teminal C, which requires long walking to it from main terminal A.

delayed flight, bag was delivered earlier than I landed, no even water was offered during the flight...

The 50 € boarding fees per ticket are completely unjustified. I lost all my savings because I arrived at the counter barely 5 minutes late (2hrs and 55mine before departure). This feels like an unnecessary penalty. It's especially disappointing considering the initial flight was canceled by WizzAir. I expect a partial refund of the 196 € paid for the boarding.

Boarding kept us waiting for ~15 minutes in the sleeve. Other than that, excellent for a low cost carrier.

Low cost carrier, you get what you pay for. Cardboard-quality seat, no recline, minimum pitch, bus-to-board service (no jetbridge), and overworked/underpaid flight attendants. But, they got the job done on-time with no major catastrophes.

The behavior of the front desk and lack of explanation of hidden fees and prices in emails send pre-flight marred things up. 1 star

2 hours delay, very disappointing, at least they didn’t cancel at all as they do often

It’s the old style plane with the old Ying Yang seats doesn’t compare to other airlines with newer planes.

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.
