Seats! The eternal problem in economy. They are like stones!!

I love Air France. This was another great experience despite a slight delay in the departure. The time was made up on flight. I would take AirFrance again when traveling to the far East. Merci beaucoup.

Everything is good except the seats are tightened no rooms for the legs,

The plane's pilots, including the captain himself, thanked me for the flight. I know it's just marketing, but it was really nice to see these people. It's a great idea. Airplane food is never "good," but the entire crew and flight organization were top-notch. I really liked Delta, and I think I've traveled all over the world, and that was something new for me. Maybe even the old planes, the B767, but next time I have a choice, Delta will be my first choice. Thank you, a satisfied passenger :)

Middle seats SUCK!!!! I paid more money than I should have because of your terrible site Kayak.com. I'll try to use your competitors going forward. I am so disappointed you would play off business class.com as business class seats

The boarding was efficient. The entertainment system was a bit unstable but Air France has a good selection of movies.

They lost my bag and I still haven’t received it yet

They lost my bag and I still have not received it

Communication on the delay, rebooking and how to get a hotel was poor. Mails, airport check-in and transfer desk said different things.

Safe and stable made me sleepy and I slept and dreamt 😂😂😂😂

Entertainment system is okay, flight attendants were ok. Leg space very narrow, I couldn’t get what I wanted to eat, dinner nor breakfast.

Excellent experience with business class area. Staff was attentive and food was amazing. Only one bathroom for business class which was logistically difficult for the staff while preparing meals. Need to offer fluids with meals. I did not get enough water to drink. But overall I rate it 5 star.

On time, great food, good drink selection! Only down was alcohol-free lounge. Lufthansa had a much better offering!

Be honest of what you sell: This was sold as Business Class on all three legs, while the JetBlue plane didn't even have business class seats, and wanted $164 for extra legroom seats.

Seat assignments for family traveling with 2 children. Loud crowd during sleep time

It was crowded… the bathrooms dirty and smelly. The seats have been made even smaller.

delayed to take off from detroit by 3 hours lost baggage in istanbul and now in venice without baggage

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.

short flight but we still got a very nice lunch and the crew did an excellent job in taking care of us

For that price on Business class, I expected to have the pod seats. These were configured as 2/3/2 and my seat mate talked half the flight with a friend across the isle, loudly. Very uncouth.

The flight was very smooth, however, the quality of food was mediocre.

The TV wasn't working No music for the whole flight from JFK to LOS It was too burring.

Flight was delayed by two hours. This really messed things up because I missed my connecting flight in Addis. I had a meeting in Entebbe which was scrapped because my flight from Addis landed later in the day.

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 629/352. 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

I paid for internet that did not work and had to pay more to have it

Boarding was disorganized. Cabin crew was rude. Food was okay. Baggage was lost in Jeddah. Called airline for the past 5 days, either no response or saying the same thing as always which was "No bag has arrived. It should be here by tonight."

A bit chaotic boarding flight but over all good experience.

The crew was unfriendly and very rude to name a few (Helina). I felt unsafe due to most of the cabinets were open while on flight. All in all the flight was ok, but the crew needed more training on customer service most of all for international flights.

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

The plane was old and the luggage racks above us were visibly shaking during turbulence. Water was dripping on our heads during landing. Our flight was over 2 hours late departing but we were not updated or told what to expect as the screen at the gate continued to read “on time”
