Not consistent with the food quality (I mean taste not freshness)

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

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

Worst airlines either. First leg was delayed because of crew not available. My connection was missed so they booked me automatically the next day! But, impossible to get anyone on site, web site does not let me access my reservation anymore, confirmed by useless agents over the phone. My 2-leg trip with part in business class arriving at 4:10pm ends up in an awful 3-leg arriving at 9pm the next day with no way to even choose the seats and of course at the very end of the plane. I can understand problems arrive but the way Air France handle it is just unacceptable. You are on your own. Apparently getting you to your destination is the only thing they consider their duty. The customer experience and fatigue is none of their concern. And I have a status with them. I will reconsider my priorities when flying with Air France and encourage everyone to do the same.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

Excellent, Lima to Paris. But Paris to Amsterdam, delayed, missed my flight and KLM treated its missed flights passengers very badly, terribly bad. No hotel accommodation given. Passengers were told to find their own hotel accommodation and claim at reasonable rate and left the booth and literally with armed Police Officers listening to passengers complains. For three hours, after moving by Uber from hotel to hotel and calling and booking online, no hotel was available. I had to return to the airport and seat/sleep on the benches, suffering the cold, and rats running around until my new allocated flight the next day. It was the most terrible KLM treatment even seen and being a Business Class passenger. Still mentally suffering to date as a result.

3 hour delay but out of their control. App said I get vouchers but when I applied for them, they were nowhere to be found in my account

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.

The food was great and the service and attitude was amazing!!

it was like a banya -so hot... They did provide a great experience with special food. one toilet broke midflight In general it was a peaceful and relaxing flight - for business class it was good.

Chicago to Istanbul was a much better experience than I expected since I’m more accustomed to Qatar Airways business class. The business lounge in the Istanbul airport was amazing - loved the lockers and phone charging stations, and the bathroom was a spa experience in itself. The onward leg from Istanbul to Karachi was utterly disappointing. Terrible plane, and I felt like I was in economy - the seats don’t come near to lying flat and the food was mediocre. What a sad downgrade - it isn’t as though the ticket on that leg was cheaper. So, on that front, there’s no contest with Qatar airways.

Second leg of Turkish Airline with Indigo is disaster for following reason. 1) You have to carry your cabin bags through ladder to boeing 777 because it was parked somewhere in parking lot and was not given a gate to board passengers and this seems to be people traveling to and fro from those flights and is not issue with flight itself. 2) I choose non vegetarian food on Turkish portal way ahead of checkin to entire trip, However the Indigo flight gave me random veg food saying they code veg food code from Turkish. 3) Indigo did not served any alcoholic beverages stating some weird reason which is non nonsensical. 4)Indigo have TV screens in front of you but it displays nothing except "Welcome Onboard" with annoying white black ground in dark flight. This is the most stupidest and annoying part because you are held hostage for 7 hours and only thing you could do is stare back at white screen which does not have entertainment package or even flight tracker. Such a shame.

nice and clean plane but the seats and the comfort was not what i expected. i expected more based on all the ads and reviews that i've read. I guess you get what you pay for in economy.

Overall it was good. Food was bad. I ordered gluten free vegetarian meal. But I got gluten free chicken for my long flight from Seattle to Istanbul. I don’t eat any kind of meat. Second meal I got eggplant with meat which I couldn’t eat. I don’t understand why we can’t get gluten free vegetarian meal for a 12 hour flight. I eat the bread and that was it.

Worse worse worse, i would not recommend this airline to anyone. Istanbul airport maybe State of the Art facility but staff is rude, only works if they get tips, and they push you to give tips even though my family had spent $50 in tips. Airline staff doesn't speak english so you really can't understand them. It was a nightmare travelling with Turkish. Never again.

As a big guy the seats are way too small for me. Would prefer more comfortable seats on these long haul flights.

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

Boeing 777 is a bad choice for a such a long flight.

The staff at IST airport could have been more helpful. Too much wasted time and the plane from IST to KHI was just horrible. The plane was not clean and smelled bad!

Check in took over an hour because printer was not working. Attendant did not know how to give free layover Addis Ababa hotel vouchers or update frequent flyer number. After repeated attempts, got voucher emailed. However hotel wanted printed voucher hence more delay. Bus time from hotel back to airport was printed 4:50 hours, but hotel reception called at 3 pm saying bus will leave at 4 pm. Then hotel reception called again saying 4:15 pm. We rushed at 4:15 pm and bus was not ready until 4:40 pm. Many audio outlets were not working in planes.

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.

My recent experience with ASKY Airlines was disappointing. The check-in process was disorganized, and I was provided with inaccurate information regarding baggage requirements, resulting in unforeseen expenses. Additionally, the ground staff demonstrated a lack of professionalism and appeared insufficiently trained to handle passenger needs effectively. Regrettably, this initial encounter has left me reluctant to consider future travel with the airline.

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.

The food was terrible and the seating was uncomfortable, but the airline did a great thing letting us board in Abbis Ababa on our connecting flight after our original flight was very delayed.

The flight is packed and it feels like the space per individual has gotten smaller. Excruciating for a 14hr flight.

Forgotten Suite inside of the top compartment but went back to ask and they didn’t leave at the lost and found place. Also the checking in was so horrible. I had multi city and one of the passenger saint have visa go go go Dubai. The Ethiopian airlines never had information about requirement for US permanent resident so couldn’t go to Dubai. And when coming back to US we were told we can not use our Addis to Washington ticket and they forced us to get new ticket. Very horrible experience.

I had a comfortable seat that makes my trip wonderful. I appreciate the Ethiopia crew, they were very helpful

The flight itself was fine. The exception is that my luggage was destroyed, and I filed a claim that I haven't heard from anyone.

United was best airlines I have seen since I got there choose united airlines
