Great staff, just very far from the main terminal, had to run to connect my flight. I had 90 minutes to spare. But my flight from Chicago was delayed also.

Great staff, just very far from the main terminal, had to run to connect my flight. I had 90 minutes to spare. But my flight from Chicago was delayed also.

My luggage is lost and nowhere to be found, no response from airline

Boarding was a shitshow. Had to bus to the gate. No separate bus and boarding process for Business Class.

The plane was very old, no power outlets. We also had to wait a long time to board. They kept moving us to different lines before we actually could step foot on the plane. We ended up being delayed an hour but we were never told or informed for any reason. After the meal I asked for a coffee which the flight attendant forgot and I had to ask again. Overall not the worst but not the best experience.

Need to pay for headsets, water, or any extra except air to breath.

Sitting space was very tight and I am not big or fat (I am 5'10" 178 Lb), so eating was very challenging. The rest was good.

Sitting space was very tight, so eating was difficult. But everything else was good.

12 hours flight. Only one meal, not enough food. At the galley only water during the flight. Lavatories not clean. Headsets at extra cost.

Need to pay for a cup of water. No food. Need to pay for headsets.

Everything should improve! Service like a low cost but prices like a premium airline. Crew in general with bad manners arguing for everything. You pay for priority access but then they use buses, so your loose your advantage to put your carry on first. That was the purpose for paying for priority. Bording is a nightmare, people accessing the plane for bothering doors, front and rear, no matter which line do you have.

why can't planes be boarded from back to front?? everything was great otherwise

Good plane, excellent food, crew and entertainment. Seats in business could use an upgrade

We were delayed 2 hours because the crew was late. They need better planning by the crew, we had to sit in uncomfortable seats waiting for them.

Difficulty to check in online, but well handled at the airport. Flight delay was unfortunate. Crew was adequate but not what we have usually experienced from BA. Seat was not comfortable.

Good Poor. service onboard No food. Low quality for economy plus

Crew was excellent, great customer service, checked luggage took 1 hour and a half to come out at the baggage claim, the only negative thing about the flight.

Boarding was odd. Gates switched and had to take a bus to the plane. Luggage got lost. Still waiting on one bag. Flight itself was very nice!

The flight was delayed over 4 hours. Business class is just slightly upgraded economy.

Boarding was 2 1/2 late no explanation Captain said he did not know why, but he rested at home for an extra couple of hours. Food was edible, Nothing more.

Boarding on the buses isn’t efficient. Overall, it was great.

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)

I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

Never happened. Flight was delayed. Had to be re rojyed

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

No leg room! Either too hot or cold with these guys!

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.

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.

Pretty normal flight was delayed due to traffic could have missed connecting flight to Venice but crew kept us well informed so we made it

Flight was on time and pretty standard. No Hiccups. I have no complaints, which is a lot to say about a 12 hour flight.

On both sides of my itinerary, the planes were old, the seats did not work, the seats were filthy, and the crew were unfriendly

-The seats could be roomier -The entertainment in English could be more current! The moves were very old!!! -They served too many carbs! What happened to fruit and yogurt!!!!

A lady with a smelly dog sat next to me

Staff were nice, we left on time and arrived early, food was good. Unfortunately, they lost one of our bags and have been unable to find it. So we are in Italy for a week for my husband‘s birthday and he does not have any of his clothing.

It was bad experience . I was about to lose my flight . The airline announced the gate very late , an hour before the flight , and you need to rush to find the gate in a big airport . The flight is a long flight and the food is poor . I difintelely not taking this airplane again

Top notch re cleanliness, comfort, operational. Attendants attentive, cheerful, courteous and professional. An unusually high-grade experience all around.

Everything. Boarding, service, food, seats, crew I'd increase the air pressure to avoid dry sinuses and after effects

The crew were great and constantly cleaning bathrooms and taking care of passengers. Flight was on time and arrived on time. Boarding was easy and hassle free. Food could have been better but decent selection. Overall recommend and will fly again.

We always use BA due to the direct flight options, we have always had a pleasant flight with BA.

There might be more food options for people who can't eat so much starch/sugar/bread/rice. Meat, cheese, walnuts/pecans for snack, maybe jerky or other kinds of meat-based snacks would be better than bread and rice and sweets. I had an extra chardonnay, which was fine. The entertainment was great.

Unfortunately, my flight was cancelled because of some sort of emergency over the Atlantic and had to return to London. While I think British Airways made every effort to mitigate the situation, I must say it was still pretty unpleasant. I do appreciate the fact, however, that British Airways put my safety first…and I think the effort to correct a bad situation was very sincere. But I think the process might be handled better in future.

Horrible leg room - coach seating with empty seat in middle on a 3 across seating. You buy business class for comfort which includes leg room. Absolutely no entertainment options either. Awful experience

Flight was 3h50 and was only provided with a packet of oat cookies and offered a cold drink. Thankfully i'd had breakfast but for a morning flight of that length some sort of breakfast should be included. There were 2 toilets for economy but due to turbulence we couldn't use them until the last 1hr which meant the queue was then huge. Would've been nice to open up the business one for those closest to the front to use.

Crew service was poor and very little difference between premium economy and economy. Disappointed.

My bags never made it on the flight and I now have to wait for them to arrive hopefully tomorrow. You can’t even track your bags in the app to see where they are since they didn’t arrive. You have to file a claim and then wait for them to inform you when you will receive your bag. We were already delayed for an hour due to baggage so I don’t understand how my bag didn’t make the flight.

One of the worst experience given the middle seat even asked for the change no one honored,boarded at the end and overall one of the worst experience

No WiFi in either flight. No leg room, the seat in front of me left dents on my knees and the tray was so low my knees propped it up if I tried to use it.

It was good although our flight to the UK was cancelled and rescheduled for two days later. This was after we were already seated on the plane. We missed the first leg of our trip. BA did put us up at a hotel and paid for our meals but we lost our hotel costs in Glasgow.
