The stewardess took a picture as a gift , if you asked for it. Every thing was very good, Especially the food, big and tasty. The service was good, they served water several times, very frequent.

The stewardess took a picture as a gift , if you asked for it. Every thing was very good, Especially the food, big and tasty. The service was good, they served water several times, very frequent.

I liked the newer aircraft CRJ-550 since it had WIFI and the seats are more spacious.

Sadly I couldn't get the food I requested as it was out. Also, if you don't want to be woken up make sure the crew knows it. My wife was woken on every service.

Three meals on a single flight is disgusting. Even if I reject them all, sleeping is impossible and all that food (especially wasted food) is just antithetical to a pleasant flight experience. People were chucking multiple abandoned trays on the floor in front of my seat.

Similar to Hyd->Dubai this too was worst airlines. Bad seats, bad seating arrangement which created lot of confusion since family member were not given seat together. However most of them changed the seat and got with the family. Cheap tactics by Emirates.

The best ever, friendly and attentive cabin crew, amazing captains who utilised their expertise for less turbulence, just overall amazing

Overall I was quite pleased with the experience; the cleanliness; the polite and attentiveness of the cabin crew; and the delicious food options.

I would never have been able to make the transfer in time without asking for a wheelchair

Good food, real silverware, polite staff, smooth landing, charging plugs, good entertainment options.

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!

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

It was great! Kept the time. Provided what was promised

The crew could have been more friendly and could have offered to make the beds. Also, Ethiad should have more vegetarian food options.

It was mediocre. Honestly, the flight was late but that didn’t bother me as I had plenty of time. The only thing that bothered me is that the crew never asked to make the beds for us in business class. Maybe the crew was exhausted and that just didn’t occur to them.

From the start of my vacation at Logan Airport, Boston it was chaotic. I'm praying my flight home is better .I'm grateful that we landed safe

On this flight...fine. The one from India to Abu Dahbi, awful.

I booked and paid for a Business Class seat for myself and my wife. 4 hours before the flight i get a call saying the plane they sent doesn't have the correct layout to accommodate all the business class seats they sold me 3 months earlier at a premium of $1500 a ticket. So they have to bump me from Business to Economy and will give me a $400 credit (total of $800 for both seats) that I could turn in at Abu Dahbi for $400 in US cash. They then promised a row that we could have to ourselves and the arm rests would go up so we could spread out for each of us. My wife was taken care of but I was put in the exit row with the flight attendents set as part of the three...and the arm rest did not go up. When we got to Abu Dahbi, they would not exchange our credit for cash as promised. Very disappointed they took my money 3 months ago and refused to reimburse for the change in seats or follow the promises made.

Kayak and Aran grant issuing business class tickets without lounge access and sometimes 1 or 2 connections in economy class. It’s very disappointing to find out that after buying the ticket. Never buy tickets on kayak and Aran grant again

There was not any issues with the Etihad Airways. Staff was excellent and I love the variety of movies and games that they provided.

Very disappointing #1 - You have to pay extra to use the business lounge, or else you sit in the cold airport for 7 hours and fall sick #2 - Did an awful job with boarding, they turned on the "last call" notice on the monitor made the passengers come running to the gate, once the passengers came close the crew would tell them - hey we are not boarding yet, this included passengers with children also, this was happening all the time, it was pitiful to see #3 - Did not have the courtesy for the passengers in the business class, there is a reasons why people choose business class, because they need to get to work, that means sleep is very important for them, in the business class, the crew members would themselves cause so much noise by closing the door in a loud way, once the crew member does it then the other passengers are also doing it, #4 - the food did not smell good, #5 - The Abu Dhabi airport is small, so not a whole lot to do, especially when the layover is 7+ hours. #6 - Did not provide the slippers with pajamas, #7 - also the pajamas also I had to ask, only after asking it was provided. #8- Asked for an extra pillow because the pillow they provided was not tall enough, the crew member said there was no additional pillow and gave me something like a blanket, I tried my best to use that as a pillow, but my head kept on sliding and that messed up my sleep and did not get deep thorough sleep Overall the airlines did not have an understanding of how to care for the passengers, especially the business class ones. Overall it was a bad experience, I would much rather spend the money with Qatar airways, the experience with Qatar is so much better.

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.

I don’t understand how they charge as much as they do for such a poor experience

I wish the plane had pod seating for business class. I had a window seat (8K) and I had to climb over the person sitting on the aisle when I needed to get up. Also there is no partition between the seats for privacy when sleeping. The Asian airlines have much nicer business class seating. Their seats are wider for better comfort when sleeping.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

Food was poor quality and the screens for entertainment didn’t work properly

It was a short flight, everything was good with it.

I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

I meant this flight was not good, the one from Tirana to Frankfurt was better!

I was very grateful for Lufthansa's role in organizing mobility support. The touchscreen on my seat was faulty: slow, stained (I couldn't get it clean), and glitchy. This made selecting movies extremely time consuming, and twice I had to start all over from the beginning.

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort

The flight crew was kind, flexible, and accommodating. The seats on the plane were extremely uncomfortable.

Check-in experience, for business call please provide a premium experience

Lost my luggage, ran out of food choices in business class, ground crew was completely unapologetic.

Excellent. The crew and flight were great. Checking in was easy and everyone was very helpful.

Entertainment devices on A380 need to be fixed, the seats might do with updates.

Everything. Employees offered to help me because I had to use a cane.

Check-in and boarding were great. On flight staff were rude and disrespectful. Paid for extra room and found it incredibly cramped. Bathrooms kept in poor condition. Overall negative experience.

Great seat in premium economy, great food and drinks throughout lots of in flight entertainment. 1 hour 40 min delayed flying out , 2 1/2 hour wait at passport control in tampa

Food is good, staff is good... Wi-fi quality is poor, disembarkment after landing is atrocious.

Flight crew was lovely. Bathrooms should have been cleaner. The handsets in business class for watching the entertainment are horrible. Very difficult to figure out which buttons are for what. I managed to get the flight maps on my screen but it wasn't easy. Never got anything else up.

Uneventful trip. Good flight crew. Food could have been better and a bit more of it. Cabin cleanliness was ok.

Inflight Services are poor compared to other airlines. They do not offer even water during 15 hr flight. Food is little in portion and I had food poisoning after last meal ( rajma chawal)

Boarding at Mumbai airport was terrible, the staff had no idea how to handle it. It was chaos - and led to a delay

My seats that I paid for were changed last minute and I had to sit in uncomfortable chairs

This was a bery good experience as it was a newer plane . AI older plane bussiness class is bad .

What a pathetic plane it was. Entertainment system didn’t work. USB port was broken. There was a hole on top of folding serving table. Broken restrooms in the middle of flight.

Our seat monitor did not Not work either way going to Vietnam. I had a bulkhead seat with plenty of room, but with No monitor, it was a long flight with no movies. Fun was good, staff was Excellent.

I will never ever book air india in the future. I was with my family and at delhi airport I had to go through too with horrible experience. My 12 years daughter saud that she will never come bqck to india the way people treated us. There was no line for bags drop off since we checked online and print tag at their Kiosk as per email instruction. People working at the counter were so careless and rude. They were keep talking to each other than taking care the customers. I will not recommend anyone to fly via air india. I had horrible experience. Especially, the staff at checking counters was very very rude and careless. I have feeling if air india won't change the way they doing their operations they will out of business in a few years. Air hostes were not happy . I did not see a smile on anyone in the plane. I called twice for the assistance and no one showed up. I hope you will sene this to the Hire authority. I left a video with an another employee of air india who asked me about my experiences. I hope they will make some changes ASAP. Regars, Mohinder Kumar
