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"

Never flown with LH before so all in all wasba good experience. Also good to know that approx 24hrs prior the flight opens up for being able to organise the seating free.

It was a short flight, no real service (which is okay). Very bumpy because of weather.

I'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

Good experience. Food was great and passengers helped rearrange seats so our family could be seated together

Great flight. Left on time, not very crowded. Quiet and the right temperature.

I really like it and travel to Europe and back with Lufthansa, but it is getting expensive, a bit beyond my me

No eye patches , socks given out for overnight flight! The snack on the short haul was a cube of chocolate! The seat was uncomfortable for a long haul - not enough cushioning!

I paid a lot of money for seat selection and was miserable for flight duration

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.

Very good service. One of my journey was by bus. But they advised by plane. Wrong information

Crew was more interested on looking at their phones than welcoming passengers during boarding.

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Missed my flight to final destination because of delayed British Airways flight. Had to spend 12 hours in airport and $1500 for new plane tickets

The crew on board were all very pleasant and happy to help. The flight had the old business class seats. The departure board in the business lounge did not update and kept on saying ' gate open' but never said boarding. When I got nervous about the departure time and walked to the gate I was told off rudely for being late.

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

The boarding process was a disaster. No one respects the boarding groups—tired old aeroplane. There are no sockets to charge phones. The cushion seats are ancient and hurts back and gluts

Check in process was unfamiliar. While receiving assistance the employees supervisor berated him for not walking the area. Lucky for us, he ignored her and helped us check in. Did not know about the baggage fees with economy basic and spent 450 GBP (nearly$600) just on bags for a total of less than 2 hours flying time (50 minutes one way) on a round trip lasting less than 3 days. Customers check their own bags at kiosk and place on conveyor themselves. No reason for such an high cost of checking bags when customers do half the work. Some destinations it’s unavoidable, but will definitely seek other airlines before British Airways for future travel. Astronomically high price for bags. Our first experience flying British Airways and very, very disappointed. Completely overpriced for the services we received.

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.
