Very bad service and food variety will never come back again

Very bad service and food variety will never come back again

My baby was with me it was really good experience with emirates

Fantastic as ever. Great staff super catering and excellent service.

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

Hospitality is good. Should improve on buggage handling because l lost a suitcase. Layover in Dubai was too long , 6 hours

Everything was superb, only bad point was that the fast track on London Heathrow arrivals was not handed out to me and I had to go back to the gate to collect it.

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

I liked theAVML food. Taste was alright and quantity was enough. Sometimes during the flight I felt that the smell from toilet was coming to the cabin

You can improve in many ways First the crew in general is good, but needs to work with passion to their works not like robots Second, collecting the ear headphones long time before landing is strange The crew should deal with the passengers with respect and descent way not like giving orders

checkin and boarding were good. Lounge was pathetic. All empty seats were having reserved tag, was very warm inside the lounge so basically we didnt utilise. The flight was A320, we blocked row 1 in economy assuming leg space will be sufficient. But it was OK, nothing great compared tot he first row of Air Arabia which we took for our trip. The food was horrible, i had the beed fwith mash potatoes. No salt, no spices nothing.

The flight was operated by IndiGo and not Qatar, which is a budget airline from India. Nevertheless, the flight was uneventful.

They didn't board by zones and it was a free for all. The 16 hour flight was the most excruciating experience of my life and the seats were TINY... with no leg space and my feet were swollen immediately. The food was so bad it was inedible.

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

Good staff, good intent, decent entertainment. More seat space would always be of benefit

The crew was courteous and efficient. There was no entertainment or liquor service on this short international flight.

It was pretty good overall. I just wish the crew didn't have to interrupt you every five seconds to ask you if you wanted anything, I mean that's what the help button is for. When someone is tired and sleepy and still getting their bearings, turning on DND button is maybe not the first thing on their mind.

From home to the airport, you must mention the terminal ready.

Food not good as good as last time flew with them

Nothing I knew what I was getting into ; no complaints when on string budget

The staff was excellent. They checked on my needs at the appropriate amount, letting me sleep when I needed, checking up when I was awake.

Maybe some more information as to why the flight got delayed I understand may be tell your customers that missiles were fired at a specific airport wouldn't be reassuring to the customers and would cause mayhem but something like recent events have cause a delay on your flight or smth

I liked the crew, the food and the foot space. I did not like the comfort of the seats.

excellent, the staff was kind and the boarding process was with no issues or hassle

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

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

Liked leg room Disliked unable to book to sit with my family on same flight without paying extra

Very unfriendly team. It was very difficult to get a cup of coffee. Legroom was extremely small. Old, dilapidated plane.

Dear Etihad Airways Customer Service, I hope this message finds you well. I am writing to express my deep disappointment with my recent flight experience on Etihad Airways, which took me from India to NYC via Abu Dhabi. My flight details are as follows: [Flight Number] on [Date]. My overall experience was marred by a series of significant issues that I believe warrant attention and improvement. These issues include: Bad Conditions of Washroom: The state of the washrooms on the flight was far from satisfactory. They were inadequately maintained and lacked the level of cleanliness one would expect during a long-haul journey. Seating Space and Comfort: The seating arrangement left much to be desired. The seats were cramped, uncomfortable, and the legroom was insufficient for such a long flight. The seats did not recline as expected, making the journey quite uncomfortable. Cabin Cleanliness: The cleanliness of the cabin, including seats and tray tables, was not up to par. The lack of cleanliness impacted the overall comfort and satisfaction of passengers. Excessive Noise: The flight was notably noisy, with disturbances and loud noises making it difficult to rest or concentrate. The noise levels were considerably disruptive. Food and Catering: The quality and variety of meals served on the flight left much to be desired. Furthermore, there were issues with accommodating dietary restrictions, which is crucial for passenger satisfaction. Hygiene and Sanitary Facilities: The condition of the restrooms was subpar, and essential hygiene supplies were not adequately provided. This falls short of expectations for a long-haul journey. Overall Experience: Regrettably, the combination of these issues significantly affected my overall experience during this long flight, making it far from the comfortable and enjoyable journey I had anticipated. I understand that maintaining high standards on long-haul flights can be challenging, but I believe it's vital to bring these concerns to your attention in the hope that they can be addressed and improved upon in the future. As a loyal Etihad Airways customer, I had higher expectations for my journey. I kindly request that you take these issues into consideration and work towards enhancing the overall passenger experience on similar routes. Your attention to these matters is greatly appreciated. Thank you for your time and understanding.

I travelled from Adu Dhabi to Melb; service was minimal at best, when I asked for a bottle of water but no meal I was told it was not available- it seemed a cup would do. The staff were un helpful & dismissive. We had a family near us who I never saw obtain any assistance from crew- they were simply avoided! Meal was simple and adequate no hot drinks were on offer until close to arriving, with a pseudo breakfast. Seats were tight despite obtaining extra leg room. I will not be flying with Etihad again and will not recommend them to family & friends.

Sri Lankan airline had less entertainment choices and Sri Lankan national carrier did not have language choices

Very poor. The flight was delayed for over an hour. Also, our baggage, including that of many passengers, approimately 180 bags did not arrive, and we are yet to receive it.

Poor, They have damaged my luggage and I have filed a claim at Colombo airport. They promised I will be in touch by the team within next 2 days but there is no One contacted me at all after 1 week. I then follow up again and received an email acknowledging my claim and claimed that they will reply in 12 days on investigation. Again, no response at all after that… Very disappointing…

All good, on time, depart.only bad side was, airxraft is too old to be in business.hope ailine will manage somethinv somewhat.all good

Was good, comparatively. A330, with good crew set.on time depature. And crew try there best, to make thing efficient.

Spesific ,Crew and cabin manager, look after all pax on board despite being in a old A320 equipment.Got free seat upgrade as well,but old style seats, no much comfert on it.But food and the spesific crew, was amazing.maintain airlanka standerd.the cabin manager, who was so much keen,keen operate as per SOP.

The staff was absolutely phenomenal but the other elements of Sri Lankan Airlines need some serious adjustments. The day started off with terrible news that the flight was cancelled from Male and that the plane went to Malta. As an American, when such delays occur, the airlines find suitable ways to accommodate their customers such as putting them in an Airport hotel or lounge while waiting for the next flight. A 1.5 hour trip turned into 12 hours with no accommodations from the Airlines except a ticket to eat breakfast. For such a Billion dollar industry, a cheap breakfast is an insult toward the customer and something greater should have been done.

Many changes need to be addressed from airport check in to flight departure. If they observe other major airlines, then they can expect what Sri Lankan airlines need to update their procedures.

Smooth takeoff and landing. Best service experience in all our travels over the years. Caring and attentive crew. Loved our flight to and fro.

not looking like a national flag carrier.. both the ground team and flight team are far from being kind and helpful. Not sure what's wrong.

Boarding from the SFO lounge is a big improvement. Although the first class dining room inside the lounge is becoming very crowded.

Decent flight, helpful middle seat blocking in business. Boarding staff was polite and helpful. Unfortunately the airport directions to this gate were a mess and the check in staff did not alert us to the confusing signage or any proactive information about the lounge. On board the flight, food and drinks were decent but average. Comparatively, SASs new business catering on this route shines above both in quality and service

we originally had premium economy seats when we booked, but because we were forced to re-book because the first leg of our journey was delayed for several hours, we had to fly economy. Less room, less comfortable.

Flight was fine. We were in business class, so lie-flat seats were appreciated. Kids were in premium and said it was nice. Flight was delayed by 3 hours, so we missed everything we had planned in London the first day.

Gates were changed at Heathrow with nothing show on the board about 200 plus people needed to take a tram to another section of the terminal. At JFK airport, we had to wait 1 hour(!) on the tarmac after a 7 hour flight to get a gate to deboard!!

I am very disappointed with the way my seat reservation was handled. My husband and I purchased Business Class tickets and also paid extra to reserve our seats. However, our reserved seats were changed without our consent, and we were assigned different seats, separating us. Since we paid specifically for reserved seats, the airline did not provide the service we purchased. I would therefore like to request a full refund of the seat reservation fees. I would appreciate your prompt response and resolution to this matter. Thank you.

I can't believe you have to pay L 3.20 for a Cup of British tea on an airlines with the name British on the plane.

Long haul flight and was really good. Comfortable plane and seats. Really great service all round and always willing to help. Lovely food and drinks (Tanqueray is my favourite Gin). Media was great and helped for the long journey.

Flight was good but couldn’t sleep because bed was so uncomfortable.

This was the return leg of my trip. Tried to do online check in several times, both on BA App and online but it kept saying " it was not possible, check in at the airport". Got to Airport 3 hours before the flight to be told the flight was overbooked and I was on standby because I hadn't checked in online!!! Was told I could go and wait at the gate in case of a no show but would actually be booked on the next flight in 4 hours. At the gate I did actually get in to the original plane... And had 2 empty seats next to me.. So much for overbooked. To add insult to injury, my baggage did not arrive in LHR and was finally delivered over 24 hours later. I don't travel with BA very often.. This experience will make it even less likely, particularly as my wife had exactly the same issue 2 days later.
