Airline reviews

Cons: "Just because I have bought my ticket on points I was not given a chauffeur driver."

Pros: "Crew helped me with a chamomile to help me sleep."
Cons: "It was quite good"

Pros: "Unprofessional crew member how to treat as GOLD member in business class cabin"
Cons: "No comment"

Pros: "I was happy with all aspects of the flight"

Pros: "I had my seat changed due to my injured leg, staff acted swiftly, flight was relaxing."
Cons: "They ran out of options on the food and considering it wasn't a full flight that surprised me."

Pros: ":("
Cons: "Don’t expect any assistance with the change of a passenger name - you will be asked to buy a new ticket without reimbursement for the mistake that is by any stretch of imagination only a duplicate bookings. What will happen is that either the travel company or the airline simply will blame you."

Pros: "Comfort. Service. Cleanliness. Efficiency. Hassle-free."
Cons: "Very small plastic cups of water. On-board on call crew service was slow."

Pros: "Movies entertainment"
Cons: "Food selection available was not good in my opinion - pretty much tailored to Indian appetite and stomachs. Very pour options for juices and alternate foods."

Pros: "Breakfast portions were too small, and choices were not great. Boarding procedures were a little chaotic due to small space, and ground staff was not very polite when ordering passengers to board."

Cons: "Child kicking seat from behind for entire flight"

Pros: "Ditto......great"

Cons: "Very poorly organized boarding"

Cons: "Airplane to late"

Pros: "Good flight on A380. Food and entertainment were great."
Cons: "We had to disembark into buses because all gates were being used."

Cons: "Boarding from connecting flight was manic, gate closing as we arrived only to then sit on the plane for about 40 mins before it moved. Extra leg room seats at extra cost are near toilets and watching the comings and goings from there is not pleasant. Staff ok but nothing special, left waiting with forms for lost luggage, little explanation. Plane decor looks tired, seats narrow. Luggage lost. Know why I like to fly Thai airways"

Cons: "Crew staff"

Pros: "Lots of selection in movies"
Cons: "There was a glitch on the entertainment system and the staff tried to reset with no luck. Our row and the back row was affected and we could not watch anything on the screen for a good 2 hrs of the flight. Boarding was rather disoriented. The ground crew did not give clear instructions to control the crowd."

Pros: "Long but ok"
Cons: "There is no reason to not like it."

Pros: "Great and friendly cabin crew. Lots of movies to chose. Food was great."
Cons: "All was great"

Pros: "I was able to uograde"
Cons: "They used a lot more miles to upgrade than I thought they would Emirates keeps saying the ticket I bought through Kayal was a super saver- well I did not find the time combo I needed to travel and the prices I found on the Emirates website and Kayak were similar to within 50$"

Pros: "Emirates leg was good. Easy checkin and I think slightly large than usual seats."
Cons: "I bought a return from Emirates with the returning flight from Australia to London as a code share with Qantas. Qantas does not honour the e-ticekts from Emirates and will NOT allow you to preselect seats online. You have to hope for a good seat at airport checkin. Too bad, as I would have been prepared to pay extra for a seat upgrade."

Pros: "More space"
Cons: "Na"

Pros: "The crew and my fruit platter."
Cons: "So many screaming babies. So many passsengers wanting a few upgrade. And a sick passenger that had to deplane resulting in delayed take off. The crew were saints- composed, polite, and embodied team spirit. So many screaming babies."

Pros: "Everything."
Cons: "Nothing."

Pros: "To be honest I liked everything with this flight"
Cons: "I didn't get upgraded to business or first class ;) Maybe next time though"

Pros: "Good service, great crew, comfortable seat and pitch."
Cons: "The food was mediocre compared to usual standards."

Pros: "We had good seats & crew were friendly, but not as good as the Sydney to Dubai crew"
Cons: "The lateness of our departure with no reason given from Dubai."

Pros: "The cabin crew were excellent. All of them. They gave me great service. It was once of the best long haul flights I've had in economy. Fantastic. I was seated in seat 80H. Please see to it that the cabin crew who serviced this area are well rewarded. If every flight had crew like these guys and gals then flying would be a lot more enjoyable."
Cons: "I really can't find anything to complain about."

Pros: "Good space for economy class"
Cons: "Announce duty free on flight is closing soon so if interested to purchase last min pls check with crew...by the time you get hold of crew I find out it’s closed - all in 5 mins, from the time I saw message and spoke with crew member it was shut. Should give a little more time on announcements, enough to get a crew member and see products to purchase."

Pros: "The planes are always beautiful, clean and atmospheric. The staff is always polite and friendly, and well put together. Never have I ever had a bad experience with Emirates."

Cons: "After exhausting flight I don't know what else to say"

Pros: "Vego food was provided Lots of meals"
Cons: "Some of the food wasn't as tasty but it's airplane food"

Cons: "Significant delay in Dubai. Food vouchers handed out while change of plane which made it like feeding time at the zoo. Late boarding on new time. Food service was 6+ hours after the vouchers were handed out. Crew spent more time socializing with each other than servicing the passengers."

Pros: "Start scurty things with people who has short time to the next flight"

Pros: "food was ok service was excellent fiji airways good Emirates nice girls and good service"
Cons: "we did not like the long wait at Dubai 9 hours in airport is very painful i think that 9 hours wait took most of our energies ."

Cons: "Ok"

Pros: "The predictable skyward gold benefits when travelling with emirates"
Cons: "The low quality Oryx lounge offerings on my Doha-Dubai return leg"

Pros: "Quick online check-in and bag drop-off at the airport. Friendly cabin crew. Juices etc. offered in between meal/snacks"
Cons: "Delayed take-off from Singapore once we had boarded-an hour just waiting to taxi. Delayed landing at Dubai due to volume of air traffic. This meant a very quick transfer to the London flight and no helpful assistance from cabin crew even though I asked for assistance, I had to hail a buggy down at the airport otherwise we would not have made it to our flight as I would not have been able to walk that far in the time available. If the flight had landed on time then there would not have been a problem."

Pros: "crew"
Cons: "crappy entertainment screens food was a bit blah (stale bread products, slimy fruit)"

Pros: "Food better than average"
Cons: "Poorly designed economy seat. Unusable wifi."

Pros: "Staff Seats Food Cleanliness Good destinations"
Cons: "Boarding process is retarded. They do way too much, too many steps, too many checkpoints, stairs, hallways, people checking tix. Too much tea and not bringing the customer what they've asked for."

Pros: "Probably the loveliest airline in the sky today"

Pros: "Did not get drinks at all until dinner was erred which was over 2 hours into the journey. May have been ok if I hadn't just run from a late arriving connection to make this leg of my flight and I was so thirsty!! Naturally they were out of what would have liked for my meal. However the worst part is that Mt luggage didn't make it to Heathrow with my flight and the service in trying to get my bags back has been shocking. Considering I was told my bags would be arriving in London 2 hours later I still do not have my bage in my possession- a day and a half later. And trying to get to talk to someone to help. This has been so frustrating and disappointing."

Cons: "Baggage took almost 2 hours to get out at return destination"

Cons: "My bag was lost and I was one of the many. Logistics at Heathrow were poorly executed to help people. It seems like they knew of the problem beforehand and didn't inform people effectively. I waited longer than necessary until I overheard that a lot of luggage didn't make it. I felt if they knew of the problem they should have gotten more people to help passengers and update them."

Cons: "Very quiet pleasant atmosphere on board, lovely staff, great food, all in all a pleasant experience"

Cons: "There was a delay"

Pros: "Everything"

Cons: "Door could not be opened st LHR for about 20 minutes longer than usual"

Pros: "Crew was professional and food was very good. Entertainment was really good."

Pros: "The most impressive service found was the baggage arrival on time despite the short transient time in Abu Dhabi. In most airline this would be missed and will arrive the next flight."

Pros: "Quiet"
Cons: "Bathroom s were dirty"

Pros: "Nothing"
Cons: "Everything."

Pros: "Nothing, they loose my luggage, so I want my luggage back in 1 day or refund my money"
Cons: "They loose my luggage."

Cons: "All the food is halal."

Pros: "The flight was on time. Food was reasonable."
Cons: "A bit more leg-room and there is some scope for improvement in the food. Also, the entertainement could have more south Indian content and also allow to access entertainement for more time."

Pros: "Flight was on time"
Cons: "foos service was terrible"

Pros: "Good crew"
Cons: "Service could have been better"

Pros: "Good value for money."
Cons: "Slow processing at boarding with unnecessary additional bag search."

Pros: "Seats near me were empty"
Cons: "There was no vegetarian food. This is a big thing. The stewardess walked past me although I was waiting to buy from duty-free."

Cons: "They upgraded me to business since I am gold member"

Pros: "I had a really good asigned seat"
Cons: "Still no Harry Potter films"

Pros: "Breakfast was slightly better than dinner choice"
Cons: "Window seat is quite cramped and I am not sure why I had to pay to choose a seat before this flight but not for my previous flight to Singapore which resulted in me getting one of the last seats available which was a pretty cramped window seat. Also too many repetitive announcements"

Pros: "The crew were pleasant and visible."
Cons: "Food quality was pretty poor. It used to be so good. I had sea bass which was so dry. There were a group of 30 people travelling together. They monopolised the lobby bar and were rowdy and noisy despite requests from the crew. The flat bed is so hard, it needs a mattress."

Pros: "No hassle at airport check in. All good"
Cons: "None"

Cons: "Unusually the crew were quite stand off. Normally cheerful and accommodating this crew gave you the feeling you were in the way and tiresome"

Pros: "I liked my seat and the food"
Cons: "I did not like the cleanliness of the bathroom I did not like their entertainment I did not like that the flight attendants were bickering at each other not professional at all"

Pros: "For a 15 hour flight out was fine. The food is good."
Cons: "Bathroom lines were usually long. Appears a few were not working."

Cons: "The seats in row 43 should only have 3 in the middle as I kept getting bumped by the trolley as the aisle narrows considerably at that point in the plane."

Pros: "Despite being nearly full it was comfortable. A fair choice on entertainment. Pleasent professional crew."
Cons: "There was a disagreement about my hand luggage. At check in it was agreed I coukd take it on board even though it was 8.9 kilos. Just before security they said no. After going back and forwards it was agreed. No fault of the airline there were several infant children close to my seat. At times it was annoying"

Pros: "The crew took care of their passengers' needs throughout the flight with plenty of food and drinks."
Cons: "My headphones or speaker did not work on my TV so I was unable to watch any movies. It was difficult to sleep as I was woken up to see if I wanted food or drink"

Pros: "The flight attendant attending to seat Numbers 19 J, 19 H and 19K is especially nice. Not the coldly professional practiced niceness but warmly professional."

Pros: "Travelled in Airbus 380 for the firstvtime and I was impressed by size of the plane and comfort in economy class. Enough of leg space to bend my leg and avoid bad blood circulation. Overall comfortable flight."
Cons: "Again I found behaviour of few Crew Members a bit rute for instance i asked hor headphone from one of the attendant and she immediately told me that it cannot be missing as she put the headphone there by herself making me feel like as if i stole the headphones. I was bit speechless though i really wanted to reply to her but it would have been rude. Second thing I did not like about flight was foir serving. In our over 7 hour flight, we were just served breakfast in the morning just 2 hours before landing. Its not healthy to keep customers hungry what if the customer is diabetic. Airline need to understand that up in the sky we are dependent on them for our basic needs and it should be respected."

Cons: "Delayed by 2.5hrs in Abu Dhabi due maintenance....better to find it on the ground than in the air, I guess!"

Pros: "Had the front seats with legroom on a 380, significantly quieter there than in Business on a 777 Was out of Heathrow within 40 mins of landing, usually a lot longer!"
Cons: "Food was minimalistic, bkfst and then a chicken sandwich on a 7 hour flight..."

Pros: "Space"
Cons: "Nothing"

Pros: "Food abd care"

Pros: "Nothing"
Cons: "Maybe if me and my son was Muslim we would have been treated with dignity and respect but will not and wasn't"

Pros: "The flight crew were both considerate and kind."
Cons: "I disliked nothing."

Pros: "Great all round experience - good flight, nice plane, comfortable and well equiped with lovely staff."
Cons: "Nothing!"

Pros: "The staff was outstanding... The plane was adequate... The food was just barely okay. I was somewhat disappointed having read trip advisory and kayak recommendations on airlines prior to leaving."
Cons: "Flew over on Royal Jordanian Airlines. The plane was like new the food was fantastic and the staff was as well. On at the home the staff was outstanding but the rest was just okay. The return trip was not as good as the Royal Jordanian experience.."

Pros: "The flight wasn't delayed..The check-in/ ticketing crew were helpful."
Cons: "My seat in 13 hour long flight was Broken! The chair wouldn't recline! The crew couldn't help saying the flight was full and couple other chairs were having the same problem (?!!!). The food was mediocre. The cabin bag size limit was very small."

Pros: "I liked the wider seats and slightly more leg-room on the Abu Dhabi/London leg of the flight, the food was good and the staff pleasant."
Cons: "I was randomly picked for an "extra security check" at the Heathrow check-in in Abu Dhabi, which seemed ridiculous after going through the Johannesburg security and x-ray check as well as the Abu Dhabi one, and then having to switch on all of my electronic equipment and be swabbed for what I assume was drugs felt a bit over-the-top."

Pros: "I had a whole row to myself! Fantastic service, very friendly crew, and great movie selection."

Cons: "The carry-on size allowance is way too small and the staff was adamant and said pay $300 (Reason: the suitcase wheels wouldn't go inside the measuring crate) Ended up buying a backpack. I have used the same bag for traveling from india on etihad. Decided never to use etihad for travel."

Pros: "Having two seated aisle was fantastic for me and my partner because it meant we didn't feel like we were disturbing anyone if we wanted to get up and go to the bathroom and have a stretch. The chairs and leg room was okay, much better than our previous flight. You are fed lots of food so you never go hungry and the entertainment was good. Having USB ports to charge your phone or other devices is fantastic."

Pros: "Service was great, check in was easy. Planes are roomy enough for economy seating. Food was decent for airplane food."
Cons: "There was a delay due to poor weather. Although I was still able to make it to my connecting flight in time, they automatically switch my flight due to my bags not having enough time to be transported to the plane. As a result, I was stranded in Abu Dhabi for 12 hours. In fairness it's not the airlines fault and they did provide a hotel and shuttle bus for my short stay. What added to the frustration was the fact that they waited for the shuttle bus to be completely full (with people sitting in aisles) before taking us to the hotel. We got there too late for dinner, since all that waiting around resulted in a two hour trip for what should have taken 20 minutes. Since we had to leave so early in the AM, we didn't get breakfast either."

Pros: "I liked the service and ease of the whole process."
Cons: "Nothing."

Cons: "The seats on the 777-333 model in economy class are the WORST I have ever experienced. Extensive neck and back paid from cramped and poorly designed seats. You are going to start losing passengers, including this one who will switch airlines. A glass of wine was so cheap and acidic I found myself running to the bathroom within 15 minutes. The food was horrible. Goodbye Etihad--I can do better."

Cons: "A380 was an excellent plane. Quiet, great entertainment... decent leg room. highly recommended."

Pros: "excellent quiet A380 plane. Enjoyed the flight even in economy"

Pros: "Blanket was provided."
Cons: "The crew attendant who checked me at Delhi airport informed that the flight to Abu Dbabi to Istanbul was a full flight and therefore the only option was to have a seat in the middle. However, near the end of my flight I went to the bathroom and noticed there were MANY open seats with more than a handful of people that had a whole row to themselves. I wonder where she got her information because what she shared with me was totally false and I am totally appaled. Also, very, very long lines to check in taking more than one hour to get boarding tickets. It is freezing on both planes."

Pros: "Everything was lovely."

Pros: "Seats where just roomy enough,let's face it,you can always use more room right. Staff was very friendly and attentive . I absolutely loved flying Etihad !"
Cons: "I would still like a roomier seat,again though, I think anybody would . I probably should have perchased first class,hmmm, should the whole plane be that comfortable?And not too much more cost . I say that would be wonderful !"

Cons: "Etihad would not put me on an early flight despite having free seats on the plane. As a result of which I had a 7.5hour layover in Abu Dhabi. If they had moved me to the earlier flight, it would have left a lasting impression on me. I am looking to join a new loyalty program (from Lufthansa) and this gesture could have gone a long way."

Cons: "Too cold in the airplane"

Pros: "nice plane"

Pros: "Staff in business very attentive and friendly. Food and beverage choices very good. Presentation excellent. Staff in economy nice enough."
Cons: "In business on the 380- where has the massage option gone on the beds?? Those awful hot sandwiches served after breakfast in economy. Greasy, fatty and more like pastries. They have been serving them for years. I've spoken to tens of people and not found one who likes them! Toilets not checked very regularly for clean ups/ tidy ups and replenishments. Online duty free showing 'not available' but when they came around it was."

Pros: "Ample room and privacy provided by the tastefully done seating pod arrangement"
Cons: "Nothing"
