The flight was delayed and the service was not good. All the new serve was beef and we don’t eat beef so we ended up buying our own meals at the airport twice.

The flight was delayed and the service was not good. All the new serve was beef and we don’t eat beef so we ended up buying our own meals at the airport twice.

What a great trip . From check in to the upgrade we received a big shout out to Cleverson who was able to help us navigate the whole process super patient and was just one of the best customer service experiences we received in a very long time . The amazing staff on the flight who went above and beyond to make sure we were comfortable amazing food and service if you have te opportunity to upgrade it's a must and well worth it.

Everything was great except the boarding experience. After the check in, they "packed us" in a small area, very hot there. It would be nice to be aware of this, I'd wait on the outside area

Seat did not recline at all, wi-FI did not work at all. Those are both very unfortunate for a 14 hour flight. Crew and food was of course very nice as always.

This777-300 is configured 2/3/2 for Biz class straight out of the 80s!!! Not to mention seats are narrow, bed does NOT FULLY RECLINE FLAT as advertised, and purser didn’t know that!! ARM REST HAS A REMOTE TABLET ON IT FURTHER CONFINING THE ALREADY NARROW SPACE!!! WHO thought this was a good design?? After flying the new A350-900 biz class Montreal to Dubai , this was a total let down!!

Child’s meal was great along with other nice touches for kids.

I had a good experience flying with Emirates. All of the flights were on time staff was very professional and kind. So I had a positive experience..

The flight from Beijing to Dubai was good. The flight from Dubai to Barcelona was excellent because of the staff on board.

The queue for checking for economy passengers was enormous! Only one desk open for economy faith s queue a mile long, whilst business and first class desks empty and unemployed. Will seriously consider changing to another next trip. Disappointed customer.

Premium Economy is not worth the extra money you pay. You are neither economy nor business. The seat doesn’t recline enough to relax your legs. Maneuvering while seated is cumbersome. Don’t recommend Premium Economy at all.

Flight on time, landed well ahead of schedule. Attendants were excellent and responsive

The crew was friendly, and the flight landed on time

Rude Iberia security crew at the Madrid terminal. No Iberia officials to be found to redress complaints at the gate. No supervisors. Nothing for processing upgrades at the gate Iberia app did not work to let me upgrade my options to higher classes. No water was offered on a hot day in Madrid. Madrid airport air conditioning was so weak that people were sweating. Never book on any airlines that codeshare with Iberia.

Comfort. Not good very little space after the person in front of you lay back.

On a more than 8 hours flight was only one meal included, which I have never experienced before. Always two meals on the overseas flight. It was very weird.

Great if not for the boarding by bus at Heathrow terminal 3. Medieval disappointing time-consuming and very hard on handicapped flyers. It was awful

Positive: It was refreshingly easy and polite check-in and boarding staff. Flight was on time and Helsinki is a very well-signposted airport. Shopping was nice as well. Flight was not full and I had lots of space in economy. Flight was perfectly on time. Negative: Food and drink not very good, but that it is normal on any airline. Didn't expect anything else.

Very good seat, very comfortable, good food, and good service.

It was a good flight, very comfortable seats for sleeping in business class. Probably the most comfortable business class seat I've ever had (20+ times in business class on various airlines). Service was good, but the only downside is my screen didn't work and it had to be reset multiple times to get it to shut off. I had to block my eyes because the screen was white almost the entire flight and I wore an eye mask when I slept. But when eating and reading in my seat, my eyes hurt because the only way to turn the screen off was reset it and the screen would only be off for a few minutes at a time.

Everything was wonderful! AirBus seats are more comfortable to sleep in as compared to the Boeing planes.

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 flight crew was exceptionally friendly and helpful. Also the seats were comfortable and roomier than many other airlines.

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

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.

Food was really mediocre for premium economy in comparison to other airlines… the crew was nowhere to be found… 14 hour flight…

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

Our flight attendant was stellar with great anticipation and attention to details. Food was very good, and overall flight, though very long, was really good.

Flight got cancelled for good (apparently due to jet fuel concerns), and we had to re-book to Hannover, Germany instead.

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.

We were experiencing delayed for 4 hours and of course they took us to Turkish airlines lounge but we could not rested up since there is no bedroom. It was tiring and long day for us🙏 Especially we didn’t fly until 5:45am morning for Miami🙏😢

On Turkish it is all about the food and the service. I am overwhelmed with the quality and variety of the dining service offered on business class. I prefer the updated A350 to the older B777 cabin layout, but both are comfortable. Flights left and arrived on time with updates from the captain. I will definitely fly with them again.

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

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.

Excellent service. Friendly and attentive flight attendants, can lay back in business class and be pretty comfortable, and delicious food. Flight on time departing and arriving.

The ground crew members at check in counter were courteous. The boarding was seamless. Flight departed as scheduled. Service on board was great

two of our bags didn't arrive - this is nonsense given we weren't connecting from anywhere and the flight wasn't full so there shouldn't have been a weight problem. Also, business class and star alliance gold, my bags should have been prioritized.

Boarding was very good, crew attentive and friendly, seat size comfy, screen size nice. However, the seatbelt segment with the buckle is extremely short, which made fastening the seatbelt very complicated. Moreover, the bluetooth pairing of the audio system didn't work. It was not possible to have proper audio. The flight info software didn't work, too.

The crew were excellent, smiling and kind. The seats were good for economy though my seat back got a bit sticky from getting out of the reclining position. The food was good for a Kosher meal, better than usual. Entertainment was okay, but there was no Wi-fi available the entire flight. Overall the flight was fine for an overnight flight. The flight attendant in my section was absolutely delightful.

boarding and flight very smooth. Crew very friendly and efficiant. Everything worked well

Even after a delay, getting off the ground, thanks for keeping me safe, the airline made certain that my connecting flight was rebooked to get me to my final destination. It was actually rebooked twice, and my luggage still managed to meet me. The airline gave me a credit for food and beverage to be used at the airport vendors, regretfully, the credit did not transfer to my final boarding pass. Oh, well…

good entertainment package but rather small seats for business class

Booked Economy but it translated to economy light for Lufthansa so now we are stuck paying an extra $75 per person both ways for our checked bags. If I had known that, I would have never booked these tickets because it came out to be more than other options. The booking in the kayak side clearly says Economy and has a link to the inormation for Lufthansa which states Economy included a checked bag. Super annoyed about that.

The flight was ok, but the chargers did not work, and the speakers in the back of the cabin did not either. The seats are too small, and the food was terrible. However, I am writing because the crew was extremely rude, not only that, but they also kept the curtains closed, forgot to clear our trays, the bathrooms were filthy, and trash was piling up. Additionally, one of the attendants had her earbuds on while in the cabin. From the movement, it seemed like she was listening to music, so not even the safety aspect was there. My neighbor s English is not good and they were very dismissive of her. When we deplaned, the crew in the back was just chatting with one another, and the first class attendant was nice and said thank you. It is nice that the crew gets along so well, but they did not take care of the passengers at all. They rushed through all the services and otherwise did not go through the cabin to offer water or anything else. i had the feeling of being unwelcome at a party. I am not a grumpy traveller, but I thought you really needed to know. Thank you, Carin

Hate their old flights, boatding, food and services. Very poor quality

The plane was late (as was my flight out from Birmingham the day before)

The plane delay due to a poor judgement of the pilot. It was the only flight that got delay due to fog.
