Easy check in. Hot snack with wine if desired. Then chocolate, tea or coffee. Altogether excellent.

Seats are quite small, but due to the plane being empty we were aloud to switch seats to have more room

The water was handed out as we were entering the plane, instead of when we are set down and our hands are free of luggage. There was absolutely no food offered from Sofia to London, except a low quality chocolate, which was not delicious. The flight between London and Miami was ok, as far as service and food, but it was absolutely freezing, throughout the whole aircraft, especially in the back seats, I had to cover my head with a scarf, besides using the blanket and still I was feeling extremely uncomfortable. The passengers seating around me shared the same opinion. We did ask for something to be done about it. The gentleman did try to adjust it, but the effect last very short time, and towards the end of the flight it was extremely cold and blowing strong again ….

Cons: "Staff seemed confused and would not let us seat at our assigned seats which we picked in order to accommodate our baby. Instead they put us in an even worse spot and decided to ignore the people that took out seats and left them be."
Cons: "Them actually refunding my flight when I couldn't legally travel due to COVID lockdowns."
Pros: "Nothing"
Cons: "To add food and to patk the plane at the linkway"
Pros: "It was a direct flight to my destination"
Cons: "Check-in took 1 hour and 30 mins. Single Check in desk for economy and business, long line. Flight went late by 50 mins on departure"
Cons: "I wanted to note that while screaming at gate D1 the stuff was beyond horrible. Lazy to talk, a lady who was on the screaming machine kept making nasty comments, really inappropriate addressing foreigners and people who speak Bulgarian. I found it highly disturbing, border line harassing. You can’t work customer service and be such a nasty grumpy person. Everywhere in the world that attitude won’t be allowed, or sanctions must apply. The lady who was collecting money for the checked bag was extremely rude and lazy. Almost kicked me out for not paying for my checked bag online. Excuse me? Why is she there then? The flight was fine. However, the flight attendance slipped the last 2 rows with drinks. Please make sure that the people who work at Sofia airport get some kind of basic human training. Unfortunately, they do not wish to make you feel welcomed or cared for."
Pros: "fast trip, clean plane"
Cons: "Was a bit different to get on a bus to take you to the actual plane"
Pros: "Nothing. Bulgarian Airlines is a fifth world company!"
Cons: "Everything! The flight from Sofia (after flying in a plane that looked like a bus from the 80s), was late over two hours. Bulgarian airlines lied to us in Sofia that we would be rerouted on other airlines and find out our new tickets only at transfer desks in milan. There were NO transfer desks"

All good! But sandwiches for breakfast need to be warm!!!!! Not cold!!! You do not want anything cold in your stomach in the morning!… think about it!

The flight was very bad, the food and the staff was very rude. My last time with them

The staff was good. Very friendly and respectful. The airline not so much. They aren't very informative at all.

LOT airlines wasn't the best. They had trouble with boarding and they didn't have my information on file the right way. They change last minute details without us knowing and everything was a HOT MESS. Lot airlines also lost my baggae which was the carseat and haven't responded to any of my emails.

My bag was lost despite an almost 8 hour layover in Warsaw. Nearly 12 hours after my arrival, I have not heard anything about it.

Cons: "The TVs didn’t work even thought the steward ESS restarted them ."
Pros: "The crew was really great, seats like in any Airbus (I guess better then Boeing)"
Cons: "Very old movies as entertainment."
Pros: "Never made on plane"
Cons: "The company booking was reserved the worse company on the world , couldn't reach them to make a changes , I had to give up my ticket and lost all the money , zero response from their side."
Pros: "Sit was not comfortable, looks like that airplane was not for long trip."
Cons: "Comfortable seats, screen, usb charger."
Pros: "New plane, comfortable seats, very nice flight attendants."
Cons: "There is no way to pre-order meals on LOT flights other than calling a Warsaw phone number. Other airlines allow this both during online check-in and at any other time as part of managing your booking."

Overall good experience. Polite crew. Good foodandentertainment. Seats are small and bit congested though.

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

All flights cancelled with no way to reach the airline

The process overall was pretty seamless, and the crew were very friendly (especially Michael). Considering we booked expecting Lufthansa and the flight was operated by United, it was still a very good service and journey overall. The in-flight entertainment was great, with lots of quality options. One slight negative was that I had selected a vegetarian meal prior to flying, but received a vegan one. I think there should be more dietary options as it meant I missed out on some food that I would have preferred (and it seemed like the standard meals and snacks had a vegetarian option anyway). There was also a group of people who were moving around a lot and being generally disruptive at the quietest part of the flight, when the lights were off and most people were sleeping. I would have appreciated staff stepping in to encourage them to be mindful of others). Towards the end of the flight (which was very early in the morning in both time zones), the lights suddenly came on and breakfast was served. In my opinion, this was too early, and everyone was rudely awoken from sleep. After breakfast was cleared away, the lights went off again for about 45 minutes, allowing people to sleep some more. Then the lights came on again for landing. It seems like if they had served breakfast later, the lights on-lights off-lights on shenanigans could have been avoided, and people could have slept longer (and staff could have rested longer too).

You only get a chocolate square and small bottle of water.!

Worst comfort that I’ve ever experienced on a flight

to be bussed around the airport, then have to sit on the plane for an hour whilst the plane was deiced not once, but twice, then to have to wait for a tug driver is unacceptable. The Captain was very good at communicating.

Seats were very small in the economy class foe the high price. Vegetarian food was not good.

Lufthansa lost our luggage. After a lot of chasing on our part we got it back. The main problem is that there was no office in Bogota to help us outside of flighttimes. The customer service phone lines had no data on our luggage. I think Lufthansa need to invest in managing communications over lost luggage or this will end with everyone taking more luggage out of hold.

The first class flight itself was first class, however getting to the airport and getting through the airport was agony. The BA flight sat on the taxiway for ages and caused us to miss our connecting flight which meant half a day lost. Our return flight on BA was cancelled so a dawn flight was made and we lost another half day. Goodby BA

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

There was some delay at Heathrow where a machine needed to "start the engines" wasn't available and they couldn't even find the team tasked to do it. Unacceptable. Caused about an hour delay and seemed unnecessary. Also saw several passengers abusing the overhead luggage situation, having too many large bags and not leaving enough space for others. The crew was good and the refreshments were good in quality and quantity.

They cancelled our ticket, gave us no warning, they reissued it 4 days prior to trip and it was cancelled again when we got to the airport- very stressful, the flight was overbooked so they drove us across Milan to malpensa

I've done hundreds of flights in my life, and this flight was one of the best I've ever taken, From beginning to end, everything went smoothly, professionally, and with a smile and friendly attitude from all employees I interacted with. The food was delicious (and free), as were the drinks. There was just a genial and effective way in the way that British Airways organized the flight -that reminded of days in the 70's, 80's, and 90's, when flying was a fun, and exciting adventure. I enjoyed and had confidence in the abilities of the flight crew, I'll be flying British Airways several more times this summer. Thank you so much for the great experience! Cheryl Olso

Some how I got “offloaded” even though I had my boarding pass Food was horrible Staff were nice and cheerful No headphones were provided

Terrible! I missed my flight to my final destination and British airlines and American Airlines keep pointing fingers on each other’s. Nobody wants to take responsibility

Overall, terrific service, accommodations, and experience. Only reason comfort was rated lower was because it was difficult to keep a comfortable sleeping position for the overnight flight, but I also had an economy seat.

Very Stress free Lounges were superb. Crews were caring. I loved it.
