On time! The wait to board standing outside was miserable. The “priority” boarding is misleading as it does not help the boarding process at all. The bag charges were very high and my expected carry on did not quite fit in the measurement box. The lobby experience at the airport was terrible! Signage and directions were inadequate. The staff was all lovely.

On time! The wait to board standing outside was miserable. The “priority” boarding is misleading as it does not help the boarding process at all. The bag charges were very high and my expected carry on did not quite fit in the measurement box. The lobby experience at the airport was terrible! Signage and directions were inadequate. The staff was all lovely.

Sadly the experience with the airline is worse one ever. Starting from the state of the inside that was filthy that flies was flying around our legs. The food is expensive than a restaurant, imagine a family of 4 spending almost £50 for just sandwich of bread and ham no tomatoes and lettuce in it and a small container of crips that is not up to 20 pieces and a can of coke or Pepsi, and unfortunately that is a person ffour hours pay of work before tax. I know the blame will go to high cost of living but even at that the price is too much.

Food and entertainment were not available, so my rating on those items isn't actually correct. There should be a "Not relevant" or "Didn't use it" option.

The flight boarded nice and early and this meant there was no sudden rush at the gate. The only down side was the cabin was very cold 🥶

Flying from Hamburg to Stansted was a nightmare if I have to be honest, the flight was due to leave at 15:50 and we ended up not taking off properly till 16:56. They really don’t have enough people doing the sorting of baggage where you get the sticker for your case before the security check, going through security was 10x more faster then the whole baggage situation.

Unnecessarily delayed and remarkably inefficient boarding contributed to a significantly delayed departure. Seats/legroom astonishingly uncomfortable even by Ryanair standards (minimal legroom plus reinforced plastic seat backs ensure you get punched hard in the knees every time the person in front moves, and as a 6-foot passenger I had nowhere else to put my legs. Upon late arrival at the gate in Luton we were kept waiting another 20 minutes before being allowed off the plane. Both Easyjet and Wizzair are currently a better bet.

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

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

expedite passengers through passport control when the airport authorities are processing inefficiently.

2hrs delay on both ways Captain has to change his mind on landing in Birmingham airport and being forced to escalate and fly again, bit scary

Folks, I'll say it again. This is easily one of my favorite airlines. I'm used to traveling with all kinds of airlines throughout the world, but you need to fix your boarding process. It's not that difficult. You have preferred and regular passengers. Just make sure they line up behind the sign on time. Ground crew needs to be more proactive. Again, I am and I will continue to be a loyal customer, but please fix this one thing. It's small, but easy to fix.

Payd for long seats for our parents and because they don’t speak English fluent they have moved them. Absolutely scam!

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.

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

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

Wizzair is a mess, don’t trust them, all flights are delayed, nothing is secure with them, they are the poorest of all companies.

Communication was impossible: feedback was missing, no alternative communication options are offered. Check-in without feedback and the status was unclear at the airport until the last minute. A whole weekend under full stress. Never fly again but never use your platform again!!!

Boarding was seamless, crew were great. Less disruptions on the night flight would have improved the experience and turning off lights earlier.

Worst customer service I've ever experienced on a flight. They downgraded my seat without giving me any other options, then sat in a seat with an arched back for 10 hours. I was not able to get ahold of any customer service representatives to understand what alternatives I might have, or how they will be handling a refund for the difference in fares between business and premium economy that I was downgraded to.

British airways needs to improve their luggage handling process and communications. The luggage was lost/left in UK. But, this was not communicated to me as a traveler and because of the wait at the carousel in Seattle (we have to go through customs and immigration on arrival to US) I missed the connecting flight and had to be rebooked. No one informed me that the luggage wasn't there, and there was no one there at the carousel to check with or help me get through security faster. I wasn't the only one- there were a lot of people waiting for luggage that didn't arrive.

My bags were lost. I waited in a line for 5 hours after I landed and got no resolution to the issue.

Easily one of the best flights I’ve ever taken. Worth it to upgrade slightly. Crew was phenomenal. Just wish the man sat next to me kept his shoes on. There should be a rule about that. But I wish I could take every flight with BA.

Poor experience at Bengaluru Airport. Slow check-in process. Boarding calls were unclear and by number (no clarification given for priority groups) and were caught in wrong queue with infant based on what was written on ticket. Aircraft seat was not comfortable. Slow initial service for flight at 03:00 where most passengers wanted to sleep - did not seem right to be serving meal after takeoff. Poor quality breakfast in morning, not offered any tea/coffee alongside Only saving grace was that this was a night flight and the plane had free high-speed Starlink wifi.

We boarded late, sat on the plane for 45 minutes, I was sweating on the plane and there was a child that screamed and kicked my seat almost the entire flight. The parent nor the crew would do anything about it. Food was very good.

I always have issues to connect with BA WIFI. Nothing to blame BA for but there is always an issue getting a gate at any London Airport whether the flight is on time or delayed. But overall a great flight.

LUGGAGE ISSUE - Upon luggage drop off the 4 staff were sharing only one functional POS machine. The contactless transaction asked for PIN, which I provided. In my app it showed 2 transactions automatically: 1 contactless denied and 1 approved after the pin input. However, no receipt came out of the POS. The lady at the baggage drop had me standing by the counter for 10 minutes to wait for the transaction to show up in their system. Which it didn't. So then we proceeded to make another payment using the chip and this time it gave a receipt. Needless to say, now I have to wait for another 7 days before I can claim the first payment back, as I was charged twice. NO ENTERTAINMENT OR FOOD ON THE SHORTER FLIGHT, just the longer one. Meaning - the plane had no screens, and the "food" was a small packet of pretzels. OVERALL GOOD STAFF on both planes.

I realize it almost has to happen, but giving up one carry-on is difficult. With the standard one in the overhead and one under the seat, I believe it could have worked. We chose British Airways because of its baggage allowance, but giving up on carry-on is a major negative in choosing BA in the future. Again, it is understandable. Everything else is top notch. Thank you.

Shocking. Faults with the plane in both directions which caused delays with no compensation

Very efficient boarding. Plane lready for take ooff10 minutes before time.

Great crew. Seats do not recline :( but it is budget so i should have known. Otherwise comfy leather chair. Slight slim chair but again budget so expected. No entertainment do makes journey boring. Recommend packing plenty of snacks and games or download plenty of films and music in your device. Staff excellent. Clean flight. On time.

Both of my flights had issues with their time slot with air traffic control, so they left over an hour late and the flight back to London was delayed by over an hour. Please provide more clarity about baggage requirements on booking sites, your website and within the app. I had to pay for extra bags at the airport when departing London, because they didn’t specify that your carry on bag can only be a backpack and not a trolley, my trolley bag fit the size requirements of the backpack but still I was made to pay

The crew at Check-in was very helpful. It’s was appreciate.

It’s a budget airline. You get what you pay for. They insisted on getting us out of the gate and into our slot on time. They got us to the destination safely. Aircraft was clean and well maintained. What more could we want

Half an hour delay. Squeezed into a small Departure Lounge with very few seats. Noisy flight with screaming unruly kids. Loud IPads and Phones. Heaven!

The flight was delayed 5 hours and I'm and invalid,I wan a refund for this

The cabin crew on that flight were super fantastic and super helpful. They were so polite and considerate that i felt i travelled with a 5star airline.

Delayed delayed delayed - always with Wizzair. Staff were friendly and well mannered but clearly the company is unorganized and the aircrafts are outdated.
