In the business class it was everything wonderful. However in the economy is a hell. BTW. When I asked to search for tickets, I ordered business and I was offered options with economy, that was not clear in the order, so I could've acted faster to rectify it.

In the business class it was everything wonderful. However in the economy is a hell. BTW. When I asked to search for tickets, I ordered business and I was offered options with economy, that was not clear in the order, so I could've acted faster to rectify it.

I am a big person and have back pain and swelling in my legs, so this was a challenging flight due to confined space. I didn't find the crew very friendly either. I will think twice before flying long distances with Qatar again, due to the lack of legroom.

It was little disheartening and disappointing. Although flight staff did a good job. But customer service didn’t do anything to resolve my issue.

Qatar maybe considered one of the best ailines in the world but nowadays it is much of a muchness with the rest

Plane was good Crew was good Food was just ok Could have had more entertainment options But overall good

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.

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

The check-in and crew staff were wonderful. The food was reasonable. The online side Qatar was very poor. Seats were very tight and not very comfortable for a 14 hour flight!

Terrible experience resolving missed connection after flight was delayed. 3 hour queue at transit desk, not enough staff, no organisation, worst ever flying experience.

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 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.

We have paid premium price for a business class Cabinet and we have received the old 777 with the following apart business class that is not to standard. It was very disappointing and it’s a very bad reputation for a premium airline company. This aeroplane should be the commission from being as a business class. We will pass this knowledge to our colleagues because the quality of business class in Etihad is not consistent and it is a lucky dip that sometimes you’re getting a good aeroplane and sometimes you’re getting their 30 years old aeroplane. The crew of the aeroplane have apologise and said that they hate this aeroplane and they have complained about it multiple times as well. Obviously Etihad is putting the economy in front of the Customer Experience. For the future we will not take this risk anymore and will fly with established company like emirates.

It was fantastic. The flight from Chicago to Abu Dahbi was fantastic. The crew, food and service were amazing. Everything was handled by the crew member assigned to us , Nicholas, was usually done before we asked for it. Highly recommend Etihad!

Etihad Check In counter/Station manager in Heathrow was bothering and not helpful at all. They are rude and not customer oriented

I didn’t have a flight because it was a fraud and you allow it. Illl never use Kayak again!!!

It’s a business class ticket but they didn’t give a lounge access

Crew was amazing as usual. Very comfortable for a 13hour flight. Check in at ATL was terrible. Ticket counter charged me $200 for a small bag. Apparently Kayak sold me a zero luggage ticket. No carry on no checked. So the check in desk charged me a bullshit $200 dollar fee for a small gym bag weighing less than 20lbs. In true 3rd party ticket buying. This will turn into a finger pointing process between Kayak and Etihad. Now I'm going to have to ship my bag back in the mail a day ahead of my return flight.

My baggage was not boarded and is still missing. I was only carring one piece of luggage and that is misplaced now I am stuck at mumbai without luggage. I had an onward journey from here

We booked a business class ticket via Underpricer. Somehow they screwed up our ticket from Abu Dhabi to Ahmedabad. We will be hesitant to book again with them.

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…

From the checking, ground handlimg was very poor.seems new personal on duty,people qho suppose to be teaching them didnt see around.new people may mislead passenger, as of flt info boards, not give proper info.even informatiin counter people dont get uptodate info.makin big ques, totally disaster.guests were not happy about it.even boarding to aircraft some BC class pax sent to aft staircase, some aft pasx sent to front door.poor ground handling.may need to improove.

Nice crew.flight delay fromBKK for some ground prep issue I guess, crew serve well to guest, and respect to guest as well. As usual AC is old,and nt much comert in compare to other rehional airliners.other than that.all good

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

Flight was on time.food is as usual good.Aircraft is old.old A320, seats aithout any display.crew serve well

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.

Was got free upgrade, on old A320.aircraft is out dated kind of.bt service ,cabin manager, tried there best.and food was excelent.

When flying from Indian Sector, should be more prepared with Indian food

I was unable to board this flight because of visa changes that I was not alerted about and I’ve been unable to contact Kayak to obtain a refund / credit anything.

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

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.

Late. And service was very slow - passengers sat for well over an hour with dirty trays etc surrounding them

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

I like everything about British Airways. Excellence. Perfect. Exquisite service.

The plane was dirty the food was awful and the boarding process took too long

Bad weather in Amritsar cancelled the flight while we were at the gate in Delhi but the ground crew took good care of us and exceeded our expectations. Once on the plane, we enjoyed the best experience we’ve had on any flight in years. Their customer support was also impressively quick to answer and immediately helpful.

Old and filthy aircraft Boarding was free for all with no zones

Food was below par Quality and None of the Entertainment systems were Working ..and we were unable to turn it off.. Due to the glare we couldn't even sleep for the entire duration of the flight ..

Very old and ill maintained flights. Seats didn’t have proper cushioning. The entertainment system was a joke. That’s the least one can expect from a 19 hour long flight.

The boarding experience was very organized and easy to follow. The flight was pleasant and the food provided was also very good. Both Delhi and Mumbai airport have metro connections which make getting around much easier.

Horrible flight. No entertainment or WiFi for a 14-hour flight. No explanations either. I’ll never fly Air India again.

Aircraft condition poor, no inflight entertainment, broken seats, seats worn, split armrests, flat seat cushions and seat would recline. Aircraft needs refitting completely!

Undisputed leader in sky for Indians. Very good crew right from ground to mid sky. Very sumptuous meals twice

We had extra baggage which is an ordinary event. The check-in counter experience for them to calculate the additional amount owed and collect payment was terrible - very manual, multiple counters to resolve, took more than 30 minutes

my experience with kayak was terrible. Team kayak just left me with a booking and limbo and preffered not to contact me.. Instead when I contacted the team they said the booking is cancelled. Seriously 5 days after booking u were waiting of my call to inform me of the incompetence of the team. This will be taken up with higher authorities
