The staff is always great. Just the fact that our flight was the only one delayed from Halifax when all other carries were still flying. It happen a year ago out of Toronto as well. All others were flying but our flight got cancelled 1 hr before the time of departure.

The staff is always great. Just the fact that our flight was the only one delayed from Halifax when all other carries were still flying. It happen a year ago out of Toronto as well. All others were flying but our flight got cancelled 1 hr before the time of departure.

The only issue had when i mentioned about comfort was the man beside me was on the larger side and took about 1/3 of my seat where i was pressed against the wall/window of the plane for the trip.

The check-in staff, boarding staff, and flight crew were all very friendly. Really miss the Porter lounge in Ottawa.

Thanks for giving a beer to everyone in the seat infront of me and then telling me that I can’t have one because they are going to land. I guess I need to pay for a seat and then pick one in the very front of the plane

The flight was delayed by more than one hour. The terminal was consequently overcrowded and hot. We lost our car reservation and hit rush hour traffic in Boston, which added two hours stuck in traffic to our trip.

Awesome, the whole way through. Thank you, this is the new Canadian Airline benchmark.

We were given a complimentary seat upgrade which was so unexpected but so lovely!

Porter was excellent. Boarding was a breeze. The seats were a little uncomfortably but the overall trip was excellent.

Only packaged snacks were served. It was a flight at lunchtime and a hot meal would have been a great.

Reserve check-in was very slow compared to regular check-in. Internet was slow

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.

Great flight and crew. Food isn't free and neither are headphones...

We were in economy class but paid for option Plus which offer you an extra snack after take off, free earplugs & blanket. The crew were very attentive. The comfort however wasn’t great, hard to be comfortable in such restraint place. Wasn’t able to sleep through out the 7hrs flight and was exhausted upon arrival.

The plane was cramped and dirty. Not enough liquid was served to stave off dehydration.

The speaker flight attendant talked over was way too loud. Hurt my ears -had to take out hearing aids.

Super. Planes were clean. Flights were on time. boarding was smooth. Flight attendants were professional.

ground crew at Casablanca as well as at Montreal was not helpful at all. specially at Montreal airport, very rude .

The flight attendants were lovely - very warm and kind. Really appreciated it.

For boarding, after family with youngsters, you should have 65 and over. Whatever rules, enforce them. It’s frustrating for those who respect them to see aggressive people rush to the gate out of turn…

eveythink, because of you I lost 100 euros for my train connection

There was a terrible delay upon arrival in Barcelona. The plane had to park a great distance from the terminal, and only one bus was available to make the ~15 minutes each way trip, meaning it was ~ 45 minutes after we landed that I finally entered the terminal.

Cold frozen fruit for breakfast was unexpected and a waste in my opinion. How about a warm bun would have been better. Otherwise great on time flight.

I used to enjoy the travelling experience, but no more. We pay more and get much less. No air travel for me on the near future.

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.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

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

No Wi-Fi or food unless you pay an expensive fee.

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.

Sitting in a hotel in Chicago because I was rebooked due to a missed connection. Very frustrating.

Flight delayed at Newark by more than 1 hour. Weather was perfect. No explanation provided. This delay made me almost miss my connecting flight at Munich. Bags from all passengers from Newark were NOT loaded onto the connecting flight to Munich. Two days without fresh clothes.

my flight was cancelled. next one scheduled 2 days later. no hotel provided. worst airline experience ever

All of my flights through Lufthansa were delayed which made travel very stressful.

It wasn't clear that there will be additional charge for checked in baggage. Very, very disappointed making me pay extra $75. Food was not tasty and not healthy. Lufthansa used to be good, not any more. Unfortunately has gone down big time and continues to go down.

Flight was great (only a short hop from London to Dublin). Wi-Fi available on board(around 2 euros), power sockets, complimentary water and biscuit. Landin/ takeoff all went without a flaw.

I was charged fees for check in bags at the airport by British Airways. It was supposed to be no charge but Kayak messed up my booking apparently and I had to pay for check in bags. I paid $175.

Good crew and on time but old plane and poor breakfast

The worst travel experience of my life. Boarding chaos, delays and disorganisation at every stage. The worst of many was sitting in freezing temperatures for 10 hours whilst asking all cabin crew to turn the heat up to no avail.

They took my carry on and checked it in. Staff in general at Heathrow are not friendly or helpful

There was no legroom whatsoever to the point where my wife dropped her phone and was unable to retrieve it as she couldn’t move. The sound system for the entertainment had a broken socket so was effectively out of action as it just crackled. Just dreadful, I will actively avoid BA in the future

Gate closed way too early - over 1 hour before departure. Put onto next flight. Ticket had been changed without notifying us.

British Airways provided prompt service and maintained excellent cleanliness throughout the flight. However, the business class seats felt tight, and the cabin temperature was uncomfortably warm, making it difficult to sleep. Since I couldn’t rest, I turned to the in-flight entertainment, but the selection was heavily focused on Paramount content, which isn’t my preference. I also found the Bollywood movie options quite limited compared to other airlines. On the positive side, the spirits selection was impressive, and the staff was exceptionally friendly and attentive.

I like Cityflyer as a semi-stand alone part of BA but I dislike mainstream BA thoroughly. A budget airline with budget service but with normal flag carrier prices.

I liked having access to all the Harry Potter movies and the food was good. The staff was also excellent. The pillows and blankets could’ve been better as mine had stains when I arrived
