Airline should consider adding a small meal at the last leg of the flight, right now there is 7 hours of no meal break.

Lounge a access was excellent as was the attentiveness and service from the crew as always. The food and drink supplied were of good quality. The entertainment system had a good selection and I liked the mapping system supplied. However the screen wild have been bigger and the operation a little smoother to navigate. The seats were barely comfortable, but adequate.

Crew and service excellent. 2 hour delay for takeoff. SQ app showed flight on time.

Headwind delayed our flight which wasn’t the airlines fault

The food wasn’t good at all. I skipped meals .

We were not given option for meals since they ran out of the other option but good thing the remaining options tasted great.

Both the staff at check-in counter and on board were pleasant and helpful. My chicken and mashed potato was good, sauce was tasty, but the zucchini, carrot n other accompanying vegetables were over-cooked a little. (I understand the meal has to be prepared earlier). Yet I would fly on Singapore Airlines again and recommend it to family and friends.

Horrendous. We upgraded and they took the money but cancelled one of our tickets. The recline action didn’t work on the seats for the flight from Singapore to London, pre booked meals but they seemed to have disappeared as well.. Phone customer service was horrendous. Took 5 phone calls and no fix. Craig at the airport was the only one who seemed to be able to get the ticket back.

The seat in economy class and legroom in Singapore airline are narrower than Korean airlines! I don’t have that comforting feeling flying with Singapore air as in the past!

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

The check-in has been the very best so far I didn't get to use my priority access which made me feel like a paid a higher price with no benefit for that I loved the food Very tasty and hot The staff friendliness, empathy could be better as it was not linear amongst the whole crew Otherwise, no complaints. I'd still fly again via Etihad Great prices despite the long 6h of waiting time

It was OK as the seat which we paid for doesn’t have any window. We paid $120 for 3 seats but it’s for nothing. Crew could not help. None of the ports worked so all our phones went dry

I had a terrible experience checking in at the airport for my flight. I booked my ticket initially through Kayak while it was promoted as a ticket that offers a carry on and 2 suit cases. (I have a screen shot as a proof of it) I selected it to buy three tickets and paid online. Couple of minutes later airfare assist which is the OTA offering the ticket called me saying My card declined. So I used a different card that went through. I was surprised that they increased the price ticket by a $167. They said the ticket no longer exists and because my card declined I had to buy a new one. So I did. The day my family and I were traveling I could not check in and when I went to the airport I was shocked to be told my ticket had no bags allowed and must pay $200 per bag for three people 6 bags mean I have to pay $1200. I called the travel agency as I feel I was scammed the confirmation didn’t say anything about the bags and they never told me the new ticket doesn’t not include any bag so they changed it after I selected it on your app without informing me. Very sneaky. The travel agency said they will reimburse me only for one bag person. Which means I still paid $600 I still feel very disappointed to pay such an expense. I have always used Kayak to buy my flight tickets and telling everyone how good your rates and app are however after this I feel I was mislead and paid more for something I should not have to. You allowing such an agency on your platform will surely hurt your reputation and level of integrity. I have all the proofs from the screen shot to the confirmation email from them, the or email offering to reimburse o e bag per person and the $1200 bag fees receipts that I paid on the desk. I must be refund the full amount and I look forward to your response.

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.

The food could be better. Toilets were smelly all along

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 my seats, I was cramped, had no overhead bin space, freezing as the flight had no temperature controls, the food was awful and served cold, when asked for snacks was told to wait and then never received any. I booked this flight as a partner through 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.

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

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

They flight was without ait conetion weather was very hot

Did not have to leave plane. However found the wait tiring with nearly a full plane boarding at Male and being unable to get out of seat due to cleaners security and a full plane boarding with hand luggage. Staff were excellent despite a long and tiring flight due to stopover.

Everything about our return trip from Colombo to Manchester was excellent. Staff were brilliant all flights. Return flights on time and all staff were brilliant. The outbound journey however was marred by cancellation of Man to Bahrain flight. No information or staff assistance. Customer Service none existent. Told to make own arrangements by none interested or understanding telephone staff who said to make own hotel arrangements and be reimbursed. CS refused to reimburse hotel or lost lounge booking or taxi fees.

The boarding was late. The check-in board said boarding closed but the boarding hadn't even started. I have spine issue but not eligible for wheelchair since I can walk. But we were taken to a plane with stairs to climb. I requested support with the handcarry and was told that I shouldn't have booked this flight without wheelchair. Instead this information should be public if this plane has sky bridge or stairs. The infotainment system did not work either. And the plane was very loud with very less legroom in economy.

Very poor experience, passengers and were not social and started a troubled with other passengers and a fight erupted

Worst flight ever.service was extremely poor and food taste was horrible.Served me mashed potatoes and chicken calling it Briyani.

From the start of the check-in process, the associate was unprofessional and claimed that my ticket was incorrect, attributing the issue to Gulf Air. However, they failed to provide any clear explanation of what was wrong. After an extended wait of 45 minutes, the issue was resolved, and we were finally issued our boarding passes. Upon arrival in Paris, we faced further delays as the stairs to deplane were not functioning, resulting in an additional 45-minute wait onboard. This delay posed a significant risk of missing my connecting flight.

Had to discuss more than 15 min regarding wheelchair they gave only at the start location. No food serv in 1 st flight. Considering flight started at 10:00 pm so had to starve for dinner. Checkin screw was polite. Food in 2 nd and 3 rd flights was not good. It was too cold in the flights. Had to ask for blankets. Missed quality all thru, though the fare was on higher side

Food could have been better Entertainment was absent even in Business Class

I like it very much. Gulf Air is always the topper rank of the world. I love it very much.

what would have been better would have been that my booking not been canceled by the system and had I been informed that the booking had been cancelled by the system I could have immediately rebooked and not found out that there was an issue when I was told by the system that I needed to book in. It would have also been good if either the booking agent or BA or anyone been in anyway useful. In the end I had to rebook a flight at an additional cost of $350. So no I'm not impressed by BA any of the other parties involved.

Boarding was poor. Why are first class passengers not boarded first?! Bus to the plane and then held on a packed bus because we were waiting for people on the bus before to finish boarding. Seat belt on the fist clas seat is very uncomfortable, cutting into your neck. Other than that crew, seating and food were all excellent. Entertainment, as usual - rubbish.

The flight was fine but no food available apart from snacks like Pringles and olives which was a problem for me as I hadn’t eaten anything that day. But the worst problem was BA left 24 suitcases in Heathrow as the flight was too full but didn’t tell anyone. So we waited for ages at Toulouse airport with no information and finally found out from the one member of staff in the baggage collection area who explained what had happened and apologised for no announcement being made but said that was their policy. Then BA contacted me today to say they have found my luggage and can deliver it to me on Tuesday - half way through my holiday!!!! So a friend has had to make a four hour round trip in his car to go and collect the luggage from the airport so we can get it today. A TOTAL SHAMBLES AND DISREGARD BY BA FOR THEIR PASSENGERS’ BEST INTERESTS.

Much much better than my previous times on British Airways the food was spot-on and the service was really genuine and attentive

Flight was delayed but my previous flight was as well so It worked to my advantage. This was my first time in first class. I don't think they ever stopped feeding us. The seating area was very spacious and comfortable. The attendants were wonderful, warm, friendly and very personable.

First time on BA but will fly with them from now on! Everything about the flight was superb!!!

Horrible experience. They broke the handle of my checked in suitcase and then refused pay for damages

We had a pretty good experience. Enjoyed both the flights. Crew was very good and helpful.

The flight was very delayed in taking off - which was out of control of the crew, but then the pilot worked hard so we only arrived about 30 minutes late. Everyone was very friendly and accommodating!

They issued seat assignments and sat my 2 year-old in the row behind me, separate from me and my daughter. Communication/ customer service was terrible. They told me to change it in London, then in London, they told me to talk to the cabin crew, then a supervisor came and stuck us in the back of the plane when we were supposed to be in row 25. Overall, they need to really work on their customer service. Additionally the food was terrible and they ran out of meals and didn’t have any kid options. To top it off there was no in-flight entertainment for the first hour of the trip.

Bad seats. Broken entertainment system. Charging port not working. Seats were broken worn out. Crew was amazing. They helped as much as they could.

Boarding was through bus even though aerobridges were empty. Major mess

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

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

The plane interior was incredibly outdated. Nothing worked. My tray table was taped together (yes, TAPED!). None of the TV monitors worked. There were no buttons to turn on the overhead lights or call for a flight attendant. There was no indication of where we were or how long it would be till we got to our destination. This was a 15 hour flight btw. I was seated near the bathrooms and after a few hours on the flight, it smelled strongly of urine. It was sickening. There was only a USB charging outlet and you had to use your phone to watch movies through their WiFi. Somehow the outdated charger made it take so long to charge my devices. I paid for my seats and they definitely did a bait and switch on me. The seats I paid for were NOT the seats that I got. I will NEVER use this airline again and I highly recommend that others don't.

The trip with Air India was better than expected starting with the check-in and the Lounge. The flight was comfortable for a 1 hour flight.

The aircraft interiors are falling apart. Felt like a waste paying for business class as it was indistinguishable from economy in any way.

Ok, where do I start, hmm! Good things first - the meals/food was tasty, the seats are comfortable and legroom in Economy was ample and foot rest with message roller is simply amazing, Wi-Fi Entertainment works well. Bad things - in-flight entertainment screens and remotes either had physical damage and or simply not working. This was the case for more than 1/2 the flight. Flight that was long haul - 12+hrs non-stop. If you want a cracker or a biscuit with your tea - forget it, they carry none. Feel like having a chilled beer - forget it as they will serve you room temperature always and every time. The crew seem young and inexperienced. Will I fly again, yes I would only because it gets me from Sydney to Delhi in 12.5 odd hours (fastest), otherwise I will never. It has been what a year or so since TATA took over but I have not seen any change, I really hope this changes.

The planes are dated and need upgrades. Seats are not comfortable and entertainment equipment doesn’t work

Lay out shows 1st row and second row given after taking payment. It's a fraud
