Brand new plane lots of room the snack was very flavourful and enjoyable

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

There were no charge points for phones on the economy seats. The seats were comfortable overall. Food was okay.. flight was on time

The flight was delayed. The aircraft was unclean. Promised seat was not given due to change in Aircraft. Not one crew on ground was in a position to give any response. Amsterdam Airport is AVIODABLE Over crowded. Over Expensive. Poor Services.

It was really nice experience by flying this klm flight.I personally recommend everyone to please try this klm flight

It was really nice journey i personally recommend klm flight

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

I’m grateful for the KLM Air France shuttle bus service to Ottawa. However due to construction and other issues related to the chaotic Uber pickup system at YUL, it’s a challenge to find the Kelios bus service to Ottawa. The signs are not clear or even available. No staff to guide passengers. It’s a stressful experience.

Flight was on time, staff are friendly and helpful onboard.

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

Food could of been a bit more premium, but everything was excellent. LOVED the innovative boarding drinks and terrific service!

Seats were very tight with poor legroom - and I am average height. During the 12 hour flight, tiny paper cups of drinks we're only offered during the super and breakfast services, with the crew nowhere to be seen in between. One of the bathrooms was out of order, leading to long lines waiting to use the remaining two available to the economy class passengers.

As a first time flyer with Turkish Airlines. My experience was very good due to the factor that there were to many passengers on the my first flight compared to my connecting flight. However, I know that nothing is perfect and all companies are trying to accommodate their passengers to the best way possible. I will always say, a FEW INCHES will go LONG WAY. That's something all airliners should consider, and not only the money aspect!!! A long time commitment is better than one time service! Thank you

Staff could have been friendlier and offered drinks more often

One of the worst days of my in Istanbul very disrespect people they changed my flight 2 times I miss one of my flight from Istanbul to DFW they forsed me to buy another ticket they do not care about customer they take advantage of you. You get scammed from every where if have other options please don't go through the Turkish airlines

Cabin was kept very hot and it was uncomfortable. Entertainment system did not work at my seat. Crew and service is fantastic

They have adopted a crazy "no paper boarding passes at all cost policy". We spent half an our at the checkin stall – my elderly mother and her grandchildren were flying. She had no phone reception for some reason (besides being an inexperienced smartphone user), the kids had dumbphones, And they still won't issue a paper boarding pass. We had to do a lengthy dance with getting the boarding pass SMS on my phone and transferring them to her phone via WiFi. This was horrible, honestly. I can't imagine how they could manage it without me being there. Trees (and airline profits) should be less important than people.

I am always amazed with the great service they offer on their regional and international flights

The entertainment selection itself was ok but the screen couldn't be turned off which was annoying because I wanted to read and not be distubed by flashing lights in front of me. I could see other people having the same problem with their screens. The crew seemed to be too busy to be bothered by our questions/requests. I found the seat quite uncomfortable, especially for a long flight. As a short person, I've accepted the inconvenience of always having seats higher than comfortable, but my neck hurt after a while because the headrest was too high and couldn't be adjusted further. The seat pockets in this plane seemed to be faulty. I could see people near me having the same problem of everything falling on the floor because it kept detaching from the back of the seat. It was pretty useless to keep anything in it, even the menu and sick bag wouldn't stay in. The food was meh. The omellete was just a hunk of egg - my next flight leg also offered omellete but was so much better than this one.

Customer service was poor everywhere. In particular in business class lounge. Stewardess were however excellent. No ability to order more than one dietary restriction in food that created awkward situations when I was offered bulgur due to being diabetic as I was also gluten free

Extremely uncomfortable seats with very little cushioning, unable to recline enough to sleep comfortably on this 13 hour overnight flight. My body was in pain by the end.

I paid extra for seating when first booking flight to be in a comfortable economy seat They still changed it to a middle seat regardless. When I asked for it to be changed back to aisle, they could only give me one at the back of the plane in the least comfortable seats.

Same as already mentioned. This was more comforting as I got my aisle seat for my knee.

excellent! movie selection just ok, but everything else was wonderful.

Charged extra amount for the baggage wait. Even it’s less than 23kgs. Those machines are showing wrong weight and they were charging money wantedly from everyone.

The boarding experience did not follow the Zones that were listed on the boarding passes. This was a two-level aircraft with many passengers. Because zones were not called out by the airline staff, there was simply a mob trying to board and it was not a pleasant experience.

Our experience on the Doha to Hyderabad segment was extremely stressful due to prolonged delays and a lack of clear communication from the airline. We were traveling as a family, including children, and the uncertainty around timing and next steps caused significant distress. There was very little proactive information provided during the delay, and we were not given clear written explanations about what was happening or how long it might take. This made it difficult to manage the situation, especially while caring for children in a transit environment. In addition, one member of our party was ultimately unable to continue travel, which added to the emotional strain and disruption of the trip. Overall, the experience highlighted gaps in communication, customer care, and handling of unexpected situations. We are sharing this feedback so that future passengers, especially families, are supported with clearer communication and better assistance during irregular operations.

I wish I knew in advance that the connecting flight was by indigo air

Plane was good Crew was good Food was just ok Could have had more entertainment options But overall good

The service was good but the food was a NO

The following is a review for a flight from Johannesburg to Washington, DC with a connection at Addis Ababa, Ethiopia and refueling landing at Rome, Italy. The flight was provided by Ethiopian Airlines. There were two of us: me and my wife on this flight. Everything was on time. Enough legroom between the seats, I was able to stretch my legs and sleep for at least some time during the 14 hour second flight (19 hours in total for both flights). Very decent meals that included two lunches and one breakfast on the flight from Addis Ababa to Washington and one lunch on the flight from Johannesburg to Addis Ababa. The lunch choices were beef, chicken and fish, I think the vegetarian option was available as well, accompanied with beans. The breakfast was a choice between egg and pancake, accompanied with a fruit salad. The egg breakfast was awesome, it came with a scrambled egg and a sausage. However, my wife mentioned unusual taste of the pancake breakfast meal, by all means those were not pancakes. What wasn't good: Externally initiated commercials on the infosystem screens, you couldn't turn the screen off. These commercials were accompanied by loud and annoying music, transmitted through the entire cabin. Obviously, there was no escape from this music as well. Additional moment: on the flight from Addis Ababa to Washington, DC, we landed at Rome for refueling. This was totally fine and it was in the flight itinerary. But, the flight attendant asked me to straighten the seat while we were at the steady position during the refueling. I can't rationalize this order except that some people just like to be a boss of some kind. Keeping the light lit in the economy cabin while keeping it dimmed in the first class also didn't improve my and my wife's feelings. Overall, the services were very good and the flight, despite its longevity, went on very smoothly.

Everything was great, the infotainment system was glitching but this was not a big deal.

To the Ethiopian Airlines Customer Relations Team, I am writing to formally express my disappointment regarding my recent travel experience with Ethiopian Airlines on flight [I629/352] . Unfortunately, the level of service provided fell significantly short of the standards I expected from your airline. I would like to highlight the following serious issues encountered during the journey: • Cabin Condition and Hygiene: The aircraft cabin was notably poorly maintained. The seating area was dirty, and there was a persistent, unpleasant odor throughout the flight, which made the environment very uncomfortable for passengers. • Inadequate Service: The overall level of service provided by the staff was unsatisfactory and did not reflect a professional passenger experience. • Baggage Loss: Upon arrival, I was informed that my luggage was lost. This is particularly distressing as it has caused significant personal inconvenience and disruption to my schedule. As a frequent traveler, I value reliability and a clean cabin environment. I request that you investigate these matters immediately, provide an update on the status of my missing baggage, and outline how you intend to compensate for these failures in service. I look forward to your prompt response and a resolution to my lost luggage claim. Sincerely, Puguh

The crew were amazing. They should improve the inflight entertainment

Delay not posted, only departure time listed- not boarding time. We left an hour late and arrived 45 min late. Restrooms had backed up sinks and toilets not flushed ) passenger error). Lots of screen for entertainment didn’t work. But we arrived with our luggage

Our first flight was delayed and when we got off that plane, nobody was really helping to direct us to the next gate. It was very frustrating. One staff simply said hurry, which wasn’t helpful. We had to go a long way to get to the next gate. Another issue on the plane itself was the bathrooms were disgusting and filthy and it didn’t seem like anybody was checking on them were cleaning them and it was a long flight. There was urine on the floor and they stunk. Also, the screen in front of my seat did not work, and I tried different headphones and still had no sound. You would think somehow those things are reviewed occasionally for working order.

They only gave us 30 minutes to make an international connecting flight. We didn’t make the connection but they did do a good job rebooking us despite the chaos. Our bags didn’t make it back and their process for customer support is pretty bad when it comes to luggage.

POSITIVES The hostesses were mostly pleasant, NEGATIVES The full flight wifi was horrible, hardly able to use it. My charger port was not working which made me use my neighbour's port which resulted in an accident which ruined her flight. During dinner, meat ran out when the cart got to us forcing us to eat vegetarian which was not great. We watched everyone around us eating meat. My wifi did not transfer to the second leg of my trip as they promised as they changed the plane. I was thrown off the window seat I booked for the 2nd leg of my journey as they changed planes, all done at my expense. This was not a cheap flight ($2600) which i hurriedly had to book to attend my mother's funeral who passed away suddenly. I was honestly disappointed with the whole saga as I heard Ethiopian Airlines was one of Africa's best.

Food hardly ever changes Videos not often updated for often travel.

Were not told that carryon laggage has to be only 12 kgs but my bag was heavier asked to pay an additional $550.00. I could have upgraded to a bussiness class for that price and no one at the gate to upgrade but able to take money for the extra weight. I felt like this was a setup scam.

Horrible airline that charged me $300 for my luggage saying my bag was excess luggage when that flight was super empty. Absolutely ridiculous never flying with them ever again!

Flight was on time. Crew was amazing, minimal announcement interruptions, clean facilities and spaces.

Very terrible airline. The flights were delayed for long hours and the customer service is terrible. Never flying with Kenya Airways again.

Overall good experience but for long distances there really needs to be more room.

there really needs to be more room with each seat for such a long flight.

They boarded backwards so our zone meant nothing!!! My TV was broken, the remote was broke, the head set jack was broke! So i was stuck for 15 hours with no form of entertainment!!! The service was ok but they didn't check on us or serve many snacks. They acted like you were a burden when you hit the call button.

The plane was delayed almost three hours because boarding was unorganized then we were delayed even longer because the plane had an issue. The plane didn't look well maintained, there was also alot of tape on the exterior. I won't fly kenya air ways again after this trip.

Sadly, flights were delayed both ways with no reasons given other than " operational".

The crew was good but the entertainment was poor . All old movies and TV shows and very few of them. Needs current entertainment. Seats too firm. Food just ok. Nice though to have option with upgrade of no one sitting in middle seat

I purchased the upgrade to have 3 seats open, so I was able to sleep 9 hours. Without that I would have been miserable
