They should resume the fast track for business / first class passengers

They should resume the fast track for business / first class passengers

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.

Excellent comfort and entertainment. Service poor..Food average with little choice.

Seat 💺 was all the way on last row. Food was okay .

Boarding, seats, entertainment and service were all great. The food was great except for the fact that there were too many sweet items.

Loved that I had an exit row seat, and there was no one else in the row! And again, I don' use on-line entertainment at all (I read or sleep) but I very much appreciate that I didn't hear anyone else's entertainment!

Flight attendants were great. Comfort of seat and lie down bed pretty good. Food was very mediocre. Wine was good (red French wine) although I should have taken advantage of having more! :-) it was too late on the flight From znz—I was tired…then too early from Dubai. Woman sitting behind me dropped a full bag of garbage on my head while I was sleeping…orange peels, wet partially eaten food and very smelly food garbage which I literally had to pick out of my hair, off my face and away from my pillow. Not the airlines fault but still a very unpleasant experience.

We was missed the flight They doesn’t lest us fly next flight without payment They charge me 606 hundred dollars What is very unacceptable,our first fight ticket was almost 2000 dollars, again paid 700 it’s hurt … airlines need to do something please

Airline did not have enough vegetarian meals for all guests, and crew were not adequately trained to handle this.

Boarding was a mess, no one managing the queues. I got my meal as the pilot announced starting commencing descent and basic drink not available. No air bridge so takes forever to deplane the A380 onto buses.

The Achilles heel of the experience with Qatar Airways is the Doha Airport, especially for travellers arriving into Doha and not transiting. This airport suffers from being ambitiously big and the immigration into Qatar being overly time taking. At the end of my particular flight in which my travel was ending in Doha, the plane parked at a very remote terminal, from where it took me 30 minutes to arrive just at the immigration counter, with fast paced walking and the time on a train inside the airport. Then, at the immigration counter it takes up to a minute or more to process each tourist visitor,due to time taking face and finger scanning processes and langugage barriers if there are questions or information to be exchanged verbally with the officers. If several planes have landed at the same time, it is not unusual that one has to wait 45 to 60 minutes in the immigration queue. In short, the frustration of arriving at Doha takes away all positive vibe of the airline, as the airline and the airport are heavily intertwined and are marketed together.

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

They didn't board by zones and it was a free for all. The 16 hour flight was the most excruciating experience of my life and the seats were TINY... with no leg space and my feet were swollen immediately. The food was so bad it was inedible.

Worst air experience in whole life . Boarding and checking was hassle as they did 3 times. Crew team was clueless about passengers need. Despite of passengers raising hand , they were resetting the program

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.

Was downgraded from business to economy due to a faulty seat in business class. However when I boarded the plane there were no less than 5 free business class seats. Will never fly Qatar Airways again

Check in desk people constrained by fear. Obvious typo on Uganda visa, even though approved, caused loss of flight. Something is definitely wrong with this system.

My carry on bag was taken by Alaska Air as we boarded in LAX! She said there was not room. There was plenty of room. I told her that my meds and personal items were in it. She did not care. She said it would be sent to my final destination, Nairobi. Well it got to Nairobi the day I was to fly home. The handle of my bag was crushed so could not retract. So I had to remove it. I had to buy converters, malaria medication. personal items. I filled out the missing form at the Nairobi airport. I asked that it be shipped to the Kisumu airport. When it was obviously not going to make it for my time in Kenya. I asked that it be sent to John Wayne Airport. NONE of that happened. I only knew it was at Nairobi because my air tag indicated it was finally in Nairobi the day I was leaving Kenya! Now I need to purchase a new carry on bag!!!

Flight was fine overall. What you would expect from economy seats. I did appreciate the amenities (eyemask, earplugs, small toothbrush and toothpaste, thin socks).

Food was good, attendants were friendly. Seats were not comfortable. Did not receive any amenities such as eyemask or earplugs that would have helped sleep. Additionally a large group of passengers boarded very late into boarding and were a disruption for almost the whole flight. Flight attendants did their best but the kids were making so much noise, kicking seats, and half the time no adult was sat with them so they weren’t being managed.

second leg was more comfortable. Customer service in Abu Dhabi is okay.

Etihad seems to have a very strict luggage enforcement. I am a very light passenger compared to other passengers which are mainly heavier. I do not understood why airlines enforce the weight restriction so strictly. I was overweight luggage of 1.5kg, but am probably 10+kg lighter than the average passenger. Other airlines are far more accommodating. Poor customer service as far as I am concerned. If weight is such an important issue to an airline they should charge passengers by total amount of body weight plus luggage. To me just ridiculous.

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.

Extremely bad food, they never gave our bags in time, the online check-in did not let us check in because we had Indian OCI not sure why we were given the option to check in then, because we couldn’t check in online we had to go in person and we were not able to change our seats and sit with our family

The staff were wonderful but the seats weren't very comfortable for a bigger guy like me.

The flight take time was changed 23 times. The system kept sending messages it will be earlier at 4am and eventually the flight was at 9am I didn’t sleep all night because of that

Bad. Flight was very uncomfortable with narrow and shallow seats, very little food and water. I will not fly etihad again.

The flight was delayed which cause me to miss my connecting flight in AbuDhsbi airport.

Etihad flight sector is a local . .give the same quality upto destination

Lovely crew - comfortable journey despite it being an older plane.

Great food, great entertainment and very helpful, caring & attentive staff.

The segment bkk ist was ok. The segment ist to yul the boarding was chaotic with 5 control before get in the plain, in addition to normal control by scanner and metal detector during transfert

The seat 7A had no padding. I needed to sit on the provided pillow.

Not worth pay business class and get service economy class

It was my first time flying with Turkish Airlines, but I found the staff—from the airport to the cabin crew—to be somewhat dismissive and overly direct. This experience left me feeling discouraged about even considering a visit to Turkey in the future.

A fairly standard 2/2 configuration. Boeing 787-9 is modern but the amenities chosen by Turkish for their seats are slightly limited - no in-seat charging, for example. Otherwise, a good flight.

Absolutely horrible experience. It's an overnight flight for over 5 hours and business class does not have beds!!!!! I had a slightly bigger than economy class seat that was broken and not even reclining correctly. I should get a refund for this flight as they changed the aircraft to a small one and that is not what I paid the business class price for!

Very good except the boarding process too forever and wasn’t organized by group. I had a heavy pack or I wouldn’t have minded. I was in business. There were no audible announcements in the waiting area about boarding and everyone packed into the boarding area. Then boarding stopped for a long time but the staff made no announcements to update waiting passengers about the holdup. The flight was good after we got on.

Professional & courteous cabin crew. Food was very good even in economy class

The flight was delayed both legs of the journey. The seats were cramped.

Super surprised with the entire experience. Business class is incredible. Flight attendants around the world could learn customer service from these people. Simply fabulous experience all the way around.

Pillow and blanket are dirty. My son got multiple bites during the flight

Flight was on time. My group paid for seat’s so that us four can be seated next to each other. We all got separated. We all got middle seats, which made it more difficult to be able to get up and stretch or use the restroom. We tried talking to the employees at China Eastern and they were of no help. We will not be taking this flight or recommend this route to others in the future. Also I will be contacting customer service on how I can get our money back for paying for assigned seats.

China eastern was fantastic. I had read so many bad reviews that had made me nervous. However, I found that the flight attendant’s, and customer service check in etc. etc. was excellent. I had no problems. I would fly with them again!

Excellent! I had read some negative reviews but I found out that it was not all was not true! The staff was courteous and helpful. The flight take off and landing was nice & easy. The food was good! I asked for a second and I got it easily and without an attitude! All was wonderful!

Excellent experience however older aeroplanes used by China Eastern Airlines.

The crew were excellent, service amazing, blankets and pillow good, cabin temperature perfect, the flight on time, food was unusual selection however plentiful, price for tickets unbeatable through Kayak. Older aeroplanes used by China Eastern was the only down side.

Delay in off-boarding due to customs at SFO... pilot announcement should have come earlier so passengers don't clog aisles.

Better good than most, if not all European airlines. If you’re stuck in an economy seat anyways, China Eastern is a good choice because of shorter flight time, being able to overfly Russia

The temperature of the plane cabin is too hot. Sweat and uncomfortable. Also my food tray was broken down drinks fall off
