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.

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.

Be on time and staff on airport could be a bit more nicest

Flight was good but delayed (45 minutes) which made other connections difficult.

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!

The chairs don't recline and the food for sale didn't looks as appetising as its prices would suggest. But that's a low coster for you. Orher than that, the flight was delightfully uneventful.

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.

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

Flight schedule was modified and the final departure time delayed.

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!!!

I am very disappointed with the way my seat reservation was handled. My husband and I purchased Business Class tickets and also paid extra to reserve our seats. However, our reserved seats were changed without our consent, and we were assigned different seats, separating us. Since we paid specifically for reserved seats, the airline did not provide the service we purchased. I would therefore like to request a full refund of the seat reservation fees. I would appreciate your prompt response and resolution to this matter. Thank you.

I can't believe you have to pay L 3.20 for a Cup of British tea on an airlines with the name British on the plane.

Long haul flight and was really good. Comfortable plane and seats. Really great service all round and always willing to help. Lovely food and drinks (Tanqueray is my favourite Gin). Media was great and helped for the long journey.

Flight was good but couldn’t sleep because bed was so uncomfortable.

This was the return leg of my trip. Tried to do online check in several times, both on BA App and online but it kept saying " it was not possible, check in at the airport". Got to Airport 3 hours before the flight to be told the flight was overbooked and I was on standby because I hadn't checked in online!!! Was told I could go and wait at the gate in case of a no show but would actually be booked on the next flight in 4 hours. At the gate I did actually get in to the original plane... And had 2 empty seats next to me.. So much for overbooked. To add insult to injury, my baggage did not arrive in LHR and was finally delivered over 24 hours later. I don't travel with BA very often.. This experience will make it even less likely, particularly as my wife had exactly the same issue 2 days later.

I couldn't check in over two days online, had to phone to secure a seat and at the airport they put me on standby, at the gate I had to push to get my seat allocated back to me! No catering, a small bottle of water and a biscuit. Yet business had a full meal and drinks service. Very poor.

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.
