The flight and crew were good. Departure and arrival were timely. Check-in was professional and helpful in Malaga on return trip (same on outbound trip from Toronto). The ad before ach program was punishing - specifically for the internet/data service with the content creator that was showed twice in each ad pod. It was so annoying I made an effort to forget the name and would not use the service. Provide an opportunity to fast forward or skip the darn ads once they have been initially viewed.

Extra attention to kids, thank you, we appreciate! Perfect landing

Over the wing seat at emergency exit only downside people using lavatory have no respect and wait in the space

Flight delayed any hour and couple of big gate changes

The pilot came out and chatted with the passengers. He explained why there was a slight delay. The crew was excellent. Very helpful. I had to buy meals for my whole family and they were in different seats, so the crew had to deal with that. They were very pleasant and accommodating and did a great job!

We were unable to land in Liberia. It was not the airline’s fault, but we had to be diverted to SJO.

We had things stolen from our luggage, we also were refused an upgrade on a flight that was not full.

When we left, it wasn't Great . People were drinking heavily, very disrespectful Extremely loud, the entire trip. I think the crew members, should have get their attention. Coming back was great.

I sat in the club. The seeds were fantastic. The meal was great and Entertainment was good. The crew was fantastic. I recommend it to everybody.

The food was small portions and not fresh. I was seated at the back of the plane so by the time the cart approached me most of the food options were sold out. The cabin crew was fantastic however.

Service Director cut all cabin lights and window screens defaulted to dark, but it was an afternoon flight going west. I spent hours trying to see what was reading as reading lights weren't working either. What the hell.

The food could have been better. The flight attendant was the friendliest and most helpful I have ever had.

Almost no food given on a 5-hour flight (only a cookie, which is almost a joke). Boarding was a mess (as always, in Montreal boarding by zones is chaotic and the lines are a total mess). The entertainment system was old and with a limited selection.

Very nice comfortable spacy Airbus 321. I liked the offer of food on the Bistro menu. The idea is very good to pay and cost was low.

Received email saying that there won’t be a seat back entertainment screen and inflight WiFi would be available. But no WiFi both ways. Say it in the email.

Staff was very attentive! Food was good for premium economy airplane food. Clearly an older plane - seat back had to be pulled up manually after being reclined.

Good, only discomfort was consistent turbulence through the 3 hour flight. Not sure if in companies control though.

No frills very ordinary, charged me twice to book my seat assignment will.need to complain for reimbursement.

Everything ok, but it was a lot of turbulence during the flight.

Crew was pleasant and efficient. The speaker system for instructions was hard to understand

Everything well done and customer oriented There entertainment system is difficult to navigate

This is one of the best flights i had. Good boarding, good seats , good food, and nuce stuff and clean toilets I took the Tourist upgrade and indianischer food , the best.

They delayed my flight from Toronto Pearson for one hour and Frankfurt to Abuja for 2HRS, So sad

Overall excellent service and Frankfurt Airport was very efficient and clean

The aircraft was old, there was no charging sockets, and the seats were narrow and uncomfortable even though I had exit row premium seats.

The service was really good. The breakfast food could’ve been better as I don’t eat sweets for breakfast and the only choice was a muffin. Overall, good experience though. Thank you.

Pretty poor across the board - flight details wrong/delayed into Lufthansa app. Seat changes made without notification. Boarding delayed (ok, that happens) but all comms in German (for flight to UK, where 85% of passengers were English). Outright fraud attempted at gate, denying 1 piece carry-on of smaller than correct size and 1 piece personal item, again, smaller than correct size. Rude gate staff. Security checks perfunctory - unattended bag not acknowledged by staff..then put on aircraft unclaimed by staff.

The flight was delayed and I was stressing the whole time about whether I would make my next flight.

Staff was great. Space in bathrooms was very good. Boarding went smoothly due to aisles. I would like more room in coach. 2 more inches would be helpful. Lost luggage was a big issue; more on the administrative side than flight related, but diminished the flight experience.

The flight crew did a good job, the main problem I had was in the layout of the pod itself. I know it does not matter but the connection for the head phones was not A- easy to find, B- very difficult to do based on the placement ( behind the right shoulder, very hard to reach, the type of plug on the frame vs the actual plug of the headphones), C due to the location and the way it connected, it did not allow me to use my own headphones, D- very low quality and very uncomfortable headphones, E- Surprisingly, very old selections of movies, for me, at least. I will still fly with Lufthansa as you deliver a very good product overall and I enjoy the quality of service, the ease and the prices. Thank you.
