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 rows of seats in economy class are seriously close to one another making eating and resting just about impossible - there is hardly any legroom. Anyone larger than average size would have an incredibly uncomfortable flight. I had to basically share my seat with the lady passenger next to me as she was too big to fit into her allotted seat.

Food was good, attendants were friendly. Seats were not comfortable. Did not receive any amenities such as eyemask or earplugs that would have helped sleep. Additionally a large group of passengers boarded very late into boarding and were a disruption for almost the whole flight. Flight attendants did their best but the kids were making so much noise, kicking seats, and half the time no adult was sat with them so they weren’t being managed.

I staff or crew they were very friendly and humbly, they done theirs service very well, I appreciate them and thank you to the company or Qatar 🇶🇦 Government for providing as good service in their flight ,once again, thank you 😊 🙏 😀 😉 👍

Crews are very rude and unhelpful. Cramped seats in economy. Foods are useless

The business class experience was awesome - I will be using QATAR airways again and it'll be business class again - appreciate the privileges afforded to the business class clients - thank you.

Lovely aircraft and I flight entertainment. Good leg room. Full flight crew struggled a bit

Food not good as good as last time flew with them

Seats very uncomfortable, impossible to sleep. Food average, bakery items not fresh. Pockets in seats not large enough to hold a book and a few other items. Cabin temperature too cold, even with blanket. Good selection of movies. Other than that 12 hours of torture!

Flight changed to Oman air under one alliance . Seating , entertainment was not up to the quality of QR . Hope my trip back from cmb Doh will operate a QR flight instead of any other under one alliance .

I booked tickets for a family of five and specifically paid extra to select our seats together. We spent nearly $1,000 extra (around $100 per seat) for extra legroom so we could sit near each other. However, despite paying for this, we ended up being separated on the flight. This caused a major issue for our family because my parents do not speak English and rely on me to translate and assist them during the journey. I do not understand why Etihad changed our reserved seats without explanation. I am extremely dissatisfied with this experience. I expect the airline to do better, and I am requesting a full refund for the seat selection fees we paid.

1 hour delay meant missed my connecting flight and 1st day of holiday

Business class ticket should include lounge access and seat selection. The food quality and varieties should be more. It was surpirise that no dessert was offered.

Kayak and Aran grant issuing business class tickets without lounge access and sometimes 1 or 2 connections in economy class. It’s very disappointing to find out that after buying the ticket. Never buy tickets on kayak and Aran grant again

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

I am a larger than average person and in my opinion i don't think it's fair to allocate a window seat to anyone who is my size or larger, i was seated between 2 large passengers on a full aircraft. The guy in the window seat also occupied a portion of the middle seat (my seat) which made my experience of flying with etihad very cramped and uncomfortable, i was flying from Abu Dhabi to Bangkok. Had this been a airbus 380 it would have been better as the seats are larger but unfortunately it wasn't so i had to endure the 6+hrs unable to get any rest

The business class experience is fantastic. The crew were polite but often unavailable even when I tried to call them! I even found myself bringing my used dishes and cutlery up to the crew because no one had come to collect it after over an hour.

Very very bad service very tight seats never ever flying with Etihad again

It feels like the seat did not have any cushion and just ply wood. The seats are so compact that no one would sit comfortably. I am a slim person and it was super hard for me to move in the seat just imagine what someone else would feel. This airline would be my last option. Singapore Air and Emirates are far far far better than this. Do not travel even for free.

The seat was not functional. Very uncomfortable to sit upright for that many hours😢. There was no legroom. Can’t move the legs or the body. We should have the option to pick our seats. There was no need to call customer support team and have them pick and we pay for the premium seats. When I called the CST regarding the seats, their response is gaslighting. Total disappointment. We have paid to be tortured by Etihad Airlines.

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

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

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

KAYAK Real time status update is not accurate.the flight inbound rejected and go around.and came back and land. Delay abt 30 min.still shows ontime.track ur self if u wana real time.and cabin crew s are nicer. Aircraft is jst ok.old airplane.and in midflight ,seems have some compressor issue.airconditioning was nt work properly either.I could litarary see guests were cheking if AC is working.bt on landing it start to gv cool.which probably some one intentionaly kept .which was so bad.even breathing was bit difficult.otjer than that.for me all ok.

This leg of the trip was smoother than compared to the initial trip. Sri Lankan Airlines still have much work to do to improve the overall travel experience.

Very good crew, very efficient. Unfortunately not all items listed in duty free catalog were available.

Very professional and well managed. On time, great staff and comfortable.

Kayak company fake total I m not travel my payment reverse plzzz my credit card

Terrible experience. Unexpected wait due to staff delay was not taken proper care. Food inflight could be better where as flight attendees on flight hospitality was 100%

Because of the bubble agreement b/w India and Srilanka, I was not allowed to board the flight to Columbo. My experience about airport representatives was good. They were through in their job and saved my family from getting stuck in Columbo (as I would not be able to fly to Doha because of bubble agreement). So by their prompt attention, such a catastrophe was avoided. For this reason, even without flying with them, I would rate them 7/10.

Generally very good. I think their service is better than some other big names I used to travel with. Their food variety is second to none - and you can place order beforehand. Their seating design is a bit awkward for service, I'd say. Flight attendants must be tall enough - long legs and arms - to reach the window seat passenger while crossing over the isle passenger. Also appreciated the variety on entertainment.

Could have used more leg room for “business class” which is basically coach with a middle seat blocked. Crew was friendly, attentive. Zero entertainment.

Generally okay. Disappointing compared to some of their competitors. My seat hadn’t been cleaned properly which was upsetting

Seats not as comfortable as I had hoped. Food was very nice, service was fine. Entertainment options very nice. Had thought the premium economy was a more plus 2-3-2 layout but it was a 2-4-2 with seats not as wide as I had expected.

I flew four flights on British Airways within two weeks. I was unable to download the boarding pass to my phone for any of the four flights. I could check-in for my flight but the system would not give me boarding pass. I tried multiple ways and multiple times. I discovered many other passengers also had the same issue with their boarding passes. No explanation or acknowledgement by BA.

The plane was a long way from departure lounge. The plane looked tired but got us there.

Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays

Because our ABZ-LHR flight was cancelled by BA for reasons they refuse to tell us--not weather--we did not make this flight and were booked on the following day. BA offered no assistance to us on the phone or in the airport, and we had to find a hotel at Heathrow on our own.

Horrible - flight was delayed by 6 hours - we boarded, were made to de-board due some technical fault; aircraft changed; special meals request on new flight - all went awry. Landed in Dulles airport; breezed thru immigration; as Business Class passengers or baggage was delivered almost 90 minutes after landing; air tags indicated the bags were just near the carousel but the unhelpful BA staff - Maria and Ghina refused to give any update - palming it off on some imaginary invisible “manager” despite air tags evidence showing it right there. So about 50-60 passengers waiting and getting infuriatingly impatient for their bags coz one container was not delivered. Finally after much argument by some other passengers Maria condescended to go to the “ramp” and within 5 minutes the baggage was delivered miraculously. Question is why couldn’t she have done it one hour earlier ? Poor poor experience once again on Business Class BA.

Poor service, antiquated plane with 2-3-2. B-class config upstairs. Tight and not comfortable—not what I expected for paying B-class! AND my bag didn’t make the transfer, bag will be delivered the day after it lands!

The flight was on time, the entire experience was very smooth. The Flight crew were incredibly professional and nice. Made us feel very comfortable

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

I will never ever book air india in the future. I was with my family and at delhi airport I had to go through too with horrible experience. My 12 years daughter saud that she will never come bqck to india the way people treated us. There was no line for bags drop off since we checked online and print tag at their Kiosk as per email instruction. People working at the counter were so careless and rude. They were keep talking to each other than taking care the customers. I will not recommend anyone to fly via air india. I had horrible experience. Especially, the staff at checking counters was very very rude and careless. I have feeling if air india won't change the way they doing their operations they will out of business in a few years. Air hostes were not happy . I did not see a smile on anyone in the plane. I called twice for the assistance and no one showed up. I hope you will sene this to the Hire authority. I left a video with an another employee of air india who asked me about my experiences. I hope they will make some changes ASAP. Regars, Mohinder Kumar

Screen are not working. Windows not clean. Staff is very good. Food is okay. Experience is good. I hope the up coming is more then betters for others airlines thank you.

The crew on the flight was great and the food was good. The flight was on time and in fact arrived earlier than scheduled. The boarding process however was not great. I had a business class ticket but I had to stand in line for about 20 minutes at the gate before I could board. The bottleneck is that at the gate they check the boarding pass and passport all over again and there is no separate lane for business class and there were only 1 agent. The aircraft is very old . The entertainment system is antiquated and the programming is sub par.

I did not expect from Tata group like this worst experience food is too worst

Airline and airport management is tooo much poor airlines staff and managers not well trained they have too much attitude flight is delayed they did not announce all is poor

Things have improved still cleanliness of aircraft and maintenance of flights, still needs attention. Crew members have become more welcoming, which is indeed a welcomed change.

Chaotic/Crowded check in. Delayed departure from LHR, resulting in a very delayed Dinner service. Since takeover by the TATAs, Air-India has become Uber commercial and not in a good way, but more like Ryanair. Most seats are now sold and at too high prices (£24 add on for a single windows seat). The promised transformation into a better (clean), efficient and professional airline is nowhere in sight ☹️ Thanks

Horrible flight conditions. Entertainment system not working. Charging points not working.
