Awful as usual the air stewardess loved her own voice and would not stop talking on coms for 2hrs please please please shut up I can’t hear my headphones and don’t want to buy juty free

Big delay on run way not much explanation why, missed a important meeting in Dublin, maybe if they did nt persist measuring everyone bag over 2 cm we would have got off on time.

The lady at the boarding gate was so rude. She was challenging people being in priority and looking them up and down as if they weren’t dressed for first class. This was Ryan air priority. We all sit in the same seats. She loudly called out to embarrass a man who she believed had cheated and got in the priority line. He had a valid priority ticket and even worked for Ryanair. Also challenging visas insisting people download them until they proved on the government website it wasn’t required to print. The Ryanair employee who was challenged said she is always like this. She also pulled people from regular boarding as they were fashionably dressed and upgraded them to priority and changed their seats. That was comical. I think she felt she should be working for Emirates first class, although they would t have stood for her rude behaviour

On time boarding, on time departure and early arrival. As it should be. Yes, the comfort and benefits are very poor, but therefore the ticket is 6 times cheaper than with a flag carrier. So I am not complaining about it. You get what you pay for.

They lost a bag and now our vacation is ruined

Flight diverted to Warsaw and passengers offloaded onto coaches whilst the plane took off again and flew to Gdansk…

Good value for the money. Good leg room. Take off and landing very good.

Seats are very small, I’m not a big person, but the person beside me was using his seat and half of mine… and this person was a bit gross but not a lot…

Was very good the flight, 15 minutes late,but was very ok!!!😊👏

On time was excellent, not serving any water and deliberate seatings apart is deplorable.

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

Flight schedule was modified and the final departure time delayed.

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.

The border control opens at 4:30 so there is no point in going in early as the wizz email suggests. Our flight utilized a plane with plastic seating which was really uncomfortable.

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

Il n’y a pas eu de vol du tout puisque celui à été déplacé à la veille sans aucune information. Aucun remboursement ni service client non plus. Scandale !

A GOOD IDEA IS TO SEND TO ME BOARDING PASS IN ADVANCE SO I DONT HAVE TO FIGHT FOR IT

Boarding was delayed and we had to get on buses to plane so group # didn't matter. No food or drinks served gratis. Seats were small, knees smashed into the seat ahead, didn't recline. Crew was excellent though.

The flight from Seattle was delayed, which made me miss my connection to Florence. I was re-booked NINE HOURS LATER!!! That’s basically a vacation day lost. British Airways needs to partner with other airlines when possible to get a more realistic travel time, if delays occur. I realize there aren’t many flights to Florence from London, so I would book differently were I to return. The actual flight from Seattle was very comfortable and the crew was great, no faults there. I enjoy British Airways, this was an anomaly.

Our original booking with Kayak -our first experience -was exactly what we wanted and worked well. Updates were friendly and reassuring as were the contacts with UnderPricer so a big win-win. We learned a lot on your reliability and will definitely put you on our organisational list for the future.

The crew could not have been more helpful, my meal was excellent, I slept peacefully until right before landing, and the BA lounge was a godsend. The only negative I encountered was the coffee both on the plane and in the lounge. Not to my taste but that’s a personal preference.

Plane and seats ok. Dinners going and coming back were not fantastic. Breakfast from Seattle to London fine with bagel, cheese and fried egg. Second meal on London to Seattle not my favorite of kind of pizza sauce in a pastry. Came with water about three different times on each of my long flights. Staff on all very friendly and helpful.

I don’t understand why a reputable airline like BA would delegate their London flights to AA. Makes no sense to me, as most domestic carriers do such a poor job these days. Terminal 3 at LHR is a total dump

We ordered kids meals - which were not kid friendly at all! (the breakfast that is - scrambled eggs on a bed of spinach and asparagus?)

Uncomfortable seats. Crazy seat assignments separating families when they could easily have put them together. Good communication from pilot about arrival time after delay in departure. Toilet ran out of water in sink. Snack box poor for flight of this length.

The bed in Club class was not very comfortable, everything else was good.

Cancelled flight minutes before boarding. Rescheduled flight was two days later
