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.

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.

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

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

We were diverted to warsaw and there was zero information. We were just forced to disembark and off we go good luck the reat of the way. We all had to go our ways to find a way home!!!! Horrible horrible and it cost us alot of money to get a hotel and trains 4:30 pm next day.

Blood contaminated tissue was stuffed to the back of the seat in front of us.

My flight was delayed 1 hour. My Mood was not great

This time round it was very good, flight delayed by 30mins but capitan put his toe to the floor and made some time up!!

we were boarded AND only after the boarding process was finished we were announced there is going to be a delay of one hour.

The flight never took off because two naughty kids, Donnie and Bibi, did a silly thing. Started a war.

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.

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

I miss my flight due to boarding pass won’t load up

Big delay because of the weather but communication not so good. Boarding already late (due to tight schedule on Wizz side). When you get in you are hurried every second even if you still need a few seconds to arrange your bags. Food far away from how it looks in the catalogue and right on row 8 already out of chocolate although you are supposed to receive one for a menu. No replacement was offered.

Check in took very long. All three priority agents left for lunch or something and the line did not move.

Sempre in ritardo, bagni sporchi e sedili sporchi con le briciole

One hour delay, landed at midnight, my hotel did not accept late check in after midnight. I had to pay for another accomodation last minute after I landed. Wizzair customer support did not reply when I asked for alternative accomodation. Very poor experience overall.

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

BA has not been handling priority luggage with any special priority. This time our luggage was distinctly very slow to arrive, well after the first half of items to arrive. Business class flights cost a lot and it would be nice to have that reflected in the speed of baggage handling! (I note that this has worsened in our long experience of BA.) On a different note, we spent 2.5 hours on the plane after landing because of an airport mishap at Boston Logan. The pilot provided reasonably frequent update but more could have been done to ensure passenger comfort, such as more beverage and maybe snack services.

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.

I understand and don't want food on a short trip, but tea and coffe (at least 1 cup) should be free. Nevertheless there was water available and the crew was nice.

Food is horrible. Flight was good and the staff were mostly men.

Much much better than my previous times on British Airways the food was spot-on and the service was really genuine and attentive

There was an unfortunate 1 hour long wait where we had to sit still on the plane. While travelling with a 10 months old that is challenging and when I stood up to comfort my baby rocking her to sleep (in order to also not disturb other passengers) one of the crew told me to sit down as we were taking off immediately. Another 15 minutes went on before we took off so definitely very uncomfortable situation and I would also say a lack of empathy from that respective lady. I do understand rules on the plane, I have been travelling for the last 15 years, but rules can be adjusted when there is knowledge of delay departure.

charging money for check in. seating kids (5 years old) without the parents. poor service. never using it again

More spacious seats. I returned from flight with a blood clot in my right leg due to the flight haul.
