You should not have to pay for WiFi in business class

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

They only had vegetarian food left on the flight which I wasn’t happy about. I didn’t get any food to eat at all.

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

Great boarding, great short flight but no entertainment whatsoever. It was supposed to have wifi but that did not work.

Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

Transavia flight, was booked as KLM but i couldnt select seat or access boarding pass with KLM at all. Crammed seating and very no frills experience all around. First and last time.

Seats very small and unable to pre purchase internet or seat upgrades

The space was tight, hardly any leg room and the crew surprisingly were busy and did not take the time to attend to passengers, felt rushed. There was a delay for check in since the systems were down the airport staffs were accommodating

I recently travelled in Business Class with Qatar Airways, and overall, it was a pleasant experience. The cabin crew stood out for their kindness and professionalism, making the journey truly comfortable. The food exceeded expectations and was exceptional in both quality and presentation. The boarding staff was courteous, though I would like to mention that the staff member responsible for checking tickets during boarding could benefit from additional training to be more welcoming. A warm and hospitable approach would enhance the passenger experience significantly. However, one aspect of the journey was particularly frustrating. The in-flight entertainment system was disappointing, as the headphones provided did not work at all due to a loose connection. This significantly impacted the experience, especially since the flight also lacked Wi-Fi service. Addressing these issues would greatly enhance the overall travel experience. Lastly, I would suggest implementing a section-wise boarding process to streamline the boarding experience and minimise potential challenges. I appreciate the efforts Qatar Airways puts into delivering high-quality service and hope to see these improvements implemented in the future.

Seating is terrible, having seats so crammed is unacceptable for a 15-hour journey. I cannot stress enough how uncomfortable it is to sit in such an aircraft. Leg space is roomier in a domestic aircraft. I have not experienced this kind of crammy seating in domestic flights either in the US or other international airlines overseas.

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

Our male flight attendant was top notch - wish I could remember his name. Boarding is never fun when I have to ride the shuttle to the middle of the tarmac and pull my carry on bags up the stairs to my seat. My knees are banged up and my shoulders give me pain, so the flight started off poorly. The seat leg rests don’t recline completely so that makes is difficult if not dangerous to get in and out of the middle seats. The entertainment system touch screens prevented one from seeing the options. They are old and the software needs to be updated. I was on six planes in the last two weeks and able to see the flight progress without any stress. Couldn’t watch anything else. I do like Qatar Airways, just not a fan of a few things.

Very unimpressed that I was dumped from the seat I had booked and paid for after check in. Apparently a family wanted to sit together, however as they all were adults I think they should have pre booked their seats like I did. I will be approaching Qatar for a refund. That and the dreadful state of the flooding toilets made me wonder how they managed to be voted the best airline. Not worth the money.

Boston to Doha was great but Doha to Dhaka was the worst experience.

Moved seats, didn't accommodate requests to change seats even though other seats were available.

Do I need to repeat my complaints about my lost carry on bag?

Horrible. After paying for seats, I was cramped, my daughters legs kept hitting the seat in front, I had no overhead bin space and no help from stewards on board, the food was served cold, when asked for snacks was told to wait and never received any, the flight was cold with no temperature controls. Entertainment was outdated. I booked this through partnership with American Airlines but will avoid in the future.

Took a long time for boarding. The flight was comfortable.

Should have had business class line in immigration. Food quality suboptimal

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

we were delayed from Athens to Abu Dhabi by an hour and a half, so I had trouble connecting the flight from there to Bali. It could have been done had they waited even 15 mins. There was another lady who was in the same boat. By the time we were half way across the terminal, they have actually already issued different flights for us to go Jakarta then to Bali. Not to mention the inconvenience of waiting over 4 hrs at the airport and the subsequent inconvenience, we did not arrive to Bali till after 800pm the next day, which means I paid for the hotel for nothing when I could have been there before noon the next day! There was little explanation. It was just as well I needed some assistance getting around, otherwise the 2 of us would have been completely lost! Not going to fly with them again!

Likes: on time departure, new plane Didn’t like:very poor quality food, very limited entertainment.no amenity kit etc.

This flight was a dreamliner so I think the space was ok for the legs, but the option for food was again limited and the crew was same.

The seat was like there is no leg space....there were no proper option for food in the airline. It seemed like the airline was at brink of bankruptcy. The crew was helpful except for a few.

Needs better seat for business class. My seat was falling apart. Also no WiFi on that flight

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.

There was more leg room than on the overseas flight, which was nice. Boarding was very well organized and the flight very comfortable.

The plane was 3 hours late. What more can I say?!.. This, plus my horrendous experience of the second leg of my trip in where the plane had to be boarded (off and on) without escalators.. but not-covered outside regular steps…!! No… this is my last flight with Lufthansa!! Never again!

Waited on tarmac 30 min before take off everything else was fine

It was a very full flight, makes it harder for flight crew.

I remember flying with Lufthansa many years ago, and it used to be an amazing airline with more technologically savvy and roomy planes, but unfortunately that isn’t the case anymore. The space between the seats is much smaller, which is ok for short flights, but definitely not for across the Atlantic flights. Not sure if I’ll opt for Lufthansa the next time, maybe just if necessary.

SEA to Munich flight was turbulent and you could hear rattling in the plane. The food was TERRIBLE, return flight was better. We will not fly Lufthansa in the future.

Flight took off late. Flew business class. Lunch choice was chicken or vegetarian gruel. Chicken was gone by the time the flight attendant got to me. Got the salad, rolls, and desert. Skipped the vegetarian gruel. Almost broke a tooth on the roll. Suspect at it was least three days old...bird food. Wheelchair service (for spouse) at ATH was outstanding. Wheelchair service at FRA was mediocre as usual/expected.

Plane was delayed about an hour but nice crew and service

I am deeply disappointed with Lufthansa’s treatment of my elderly parents during their recent flight. They were supposed to receive assistance with wheelchair service, but the experience was nothing short of a nightmare. Upon arriving at the airport, my parents were left stranded and confused, with no staff available to guide them. Despite being promised help, they were ignored by the ground staff, who were not only indifferent but also incredibly rude. To make matters worse, some of the employees made racist comments, which is absolutely unacceptable especially for passengers with special needs. We will never fly Lufthansa again and urge others to reconsider if they need assistance. My parents were left to navigate a busy airport on their own, which is both dangerous and stressful for elderly passengers with limited mobility. This level of neglect is inexcusable, especially from an airline that claims to prioritize passenger safety and comfort.
