Paid $10 for wifi for full flight duration and the wifi wasn’t available after initial 2 hours

My baggage is lost. Flight cancelled, Rebooked ticket through long routes. Mental stress, emotional hurt

The flight overall was good. The attendants did a good job except that 1 female had too much fragrance on. The other things that made the flight unpleasant were out of the airlines control.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I would love the entertainment center to be updated with more content. The flight to Doha had more options than the one to Miami

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

Not sure how we end up with American Airlines instead of Qatar Airways. From Philadelphia to Qatar they boarded us then they asked us to unload. After 30 minutes later they board us again. The inside the plane it was burning hot and we were sweating like crazy. Crew members are absolute rude. The way they served the passengers were horrible. One of the crew members hit my knee with food cart and kept going. I was holding an ice pack for almost 2 hours. I am still with the pain.

I felt that when I was rerouted it should have been to business class.

The flight was smooth Thank God but the delays and changing gates for 3-4 times made me so tired of walking back and forth with heavy bags I thought I was going to pass out with heavy headaches but Thank God finally found the final gate and home safe. These delays happen anytime for important reasons so just be patient when you come across these situations.

It was a disaster. The crew was so rude and had no professionalism. She dropped something onto the floor, then took it from the floor and put it into the food tray. Also, when she got some spilling, she went straight to the toilet, got some tissue and started cleaning the food trolley

I cant wait for planes to have shorter rows with more space! otherwise, all fine thankyou

They lost the stroller and car seat which they found after 4 days, and on the way back they damaged the stroller.

Damage lagguage, They lost the stroller and car seat which they found after 4 days, and on the way back they damaged the stroller.

Same situation saudi lost my pram and car seat and damaged lagguage

My gag was left at liayad airport when I landed at jeddah airport 9 am I waited for my bags at jeddah airport till 2.45 pm almost 6 hrs bad very bad

Apart from chaotic boarding - which I totally understand was outside the control of gate staff. It was comfortable mid haul flight. Well done to cabin crew for their patience and hospitality with largely elderly passengers returning from pilgrimage.

The intettainme is old stuff and difficult to get by WiFi and the chair is not comfortable at all although the staff were excellent but beyond their limited

Overall a great experience, no movies were available. Bags were delivered a bit late. Seat controls were not working well. I couldn't make my bed fully flat.

It is almost 7 hours journey ,you should have provided with TV entertainment and mobile charging

In Colombo when I-drop my baggage Sri Lanka air line crew not polite way talk very rude

Same problem place in the middle so small Im 1,85 m so not good 👍

Did not provided with option for class upgrade. Staff at gate was not able and willing to accommodate with class upgrade, eather with plenty empty spots in business and first class.

Old plane, old entertainment system. It wasn't working throughout the entire flight. I was offered to connect to their system via Wifi to watch on my phone. Crew wasn't very helpful except one lady who turned the experience around.

Stewardess was attentive and was actively roamin to check the passengers on the biz class

A380 First Class Apartments were phenomenal. Comfortable bed and matress cover, superior vegetarian five course meal, shower, small business lounge and plenty of exercise walking around the aircraft.

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.

Flight was delayed due to slow boarding process by etihad. Update food options and movies as well.

Should have had business class line in immigration. Food quality suboptimal

The best airline for international travel in terms of value you get in business class (service/cost)

I liked the overall flight experience. However, Turkish officials could do a better job at guiding non-Turkish speakers to their connecting flight gates in such a huge & vast airport.

Very small and cramped aisles and seats. Food was poor but the fresh hot roll and hummus was good. No cans of soda given but they had small bottles of water. Crew was nice and pleasant and kept bathroom clean.

We couldn’t fly to Chicago on our booked flight. The flight was overbooked.

Small seat space for 13 hours flight, they charged for baggage , very bad quality of food,

I was sitting almost in the back, the seats are very tight and there’s no legroom, it’s uncomfortable for a long distance

Absolute worst airline. Charged us $720 to check 4 bags (2 of which were carry-on). Entertainment systems didnt work. And on a 12 hour flight they served 2 meals and never once came around outside of those 2 meals with a beverage or cup of water. Will never fly them again.

Took forever to board. They made announcements without the loudspeaker and since the waiting room was full of screaming kids, no one could hear what they were saying. The business class sleeper seats were designed for tall skinny people. When partially reclined there was nowhere to rest my feet because they did not reach the footrest. and when fully reclined there wasn't room at my sides for my arms. Definitely one of the worst sleeper seats I have ever had.

About an hour delay but we made it to Chicago. I feel that the smaller connecting flights are the ones that cause the delays on the bigger planes that fly international.

Amazing trip! No delays, no broken or lost luggage, and amazing food.
