Fly Dubai takes low cost and thrift to new depths in terms of service levels, terminal 2 is grossly inadequate for capacity and resembles a crowded buss or railway station,, the fly dubai( Emirates) flight is never on time(was 2.5 hrs delayed), and this is not an isolated experience, the flght air conditioning was turned low while we waited on the tarmac for take clearance to save fuel, should say more!!!! The depths! I only fly this airline from a compulsion, emirates code shares for connections to Muscat

I liked everything: the service, the food, the cleanness. I flew last year with Qatar Airways, so I can compare. Emirates did much better! Especially their meals and service.

Premium economy was worth it-comfort was definitely better than economy class. The seats were more comfortable, blankets and pillows thicker

Bathrooms were amazing and first class seat was very comfortable. Food was edible but not up to the standards of other first class meals on other airlines. But Caviar was amazing! So much caviar. Dom Perignon 2015 was room temperature. It would have been amazing if it was chilled down a bit more. Slippers were amazing and amenity kit requested was beautiful. Requested Pajamas never came so can’t tell you how nice they were. Loved the design of the seat and personal storage. Suite was much smaller than other airline’s first class and tv screen was tiny and remote difficult to use. I probably wouldn’t pay for this flight again.

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.

Crew were very good. Food service was a little slow and disappointing not having on demand dining and only 3 options. Amenity kits and pyjamas were excellent.

This was my first time flying with Emirates. Overall, the experience was very good. I thought the seats in economy would have been a bit more comfortable, but, they seem to be on par with other airlines. The food was excellent and very satisfying. If you can afford it, I would definitely suggest upgrading to at lest premium economy seats for long haul flights.

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

The flight from Beijing to Dubai was good. The flight from Dubai to Barcelona was excellent because of the staff on board.

Charged extra amount for the baggage wait. Even it’s less than 23kgs. Those machines are showing wrong weight and they were charging money wantedly from everyone.

Flight departed punctually on time. Unfortunately it seems because the destination airport is a secondary airport the airline sees it fit to operate a plane with lower comfort and offerings. There was no inflight entertainment, wifi or let alone a screen to at least track flight status for remaining flight time.

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

As good as you can expect an economy flight from Europe to Australia to be. Nothing agains Qatar, just feels like every new generation of plane gets tighter.

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Good. It would be great if comfort seats were available

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

Awful plane to Tashkent. Not even possible to sleep. In business class does not even recline fully

Worse fight I ever take since I start flying , still have even made home , and crew abandon us half way home . No water no food and no even anyone to answer our questions

Seats very small and unable to pre purchase internet or seat upgrades

The crew could have been more friendly and could have offered to make the beds. Also, Ethiad should have more vegetarian food options.

It was mediocre. Honestly, the flight was late but that didn’t bother me as I had plenty of time. The only thing that bothered me is that the crew never asked to make the beds for us in business class. Maybe the crew was exhausted and that just didn’t occur to them.

On this flight...fine. The one from India to Abu Dahbi, awful.

I booked and paid for a Business Class seat for myself and my wife. 4 hours before the flight i get a call saying the plane they sent doesn't have the correct layout to accommodate all the business class seats they sold me 3 months earlier at a premium of $1500 a ticket. So they have to bump me from Business to Economy and will give me a $400 credit (total of $800 for both seats) that I could turn in at Abu Dahbi for $400 in US cash. They then promised a row that we could have to ourselves and the arm rests would go up so we could spread out for each of us. My wife was taken care of but I was put in the exit row with the flight attendents set as part of the three...and the arm rest did not go up. When we got to Abu Dahbi, they would not exchange our credit for cash as promised. Very disappointed they took my money 3 months ago and refused to reimburse for the change in seats or follow the promises made.

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

Was so disappointing. Business class with no TV, uncomfortable seats. Had much higher expectations.

I missed my flight ,staff unhelpful, they sat and watched me wait ,gangway door closed, English was a problem no announcement I was on time now I missed my month vacation ,lost 1400 bucks no refund I'm sick to my stomach

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

Poor boarding with incorrect gate numbers. Poor service they told me to throw away brand new water bottles. Poor immigration officers most likely American who hates Muslims. Poor service in the plane with no Urdu language sign posted anywhere. Horrible seats with no comfort at all they think people traveling in economy are animals. Slow food and water services. Slow baggage arrival.

Very delayed and uncomfortable seats. Nothing written in Urdu for Pakistanis. Tons of Pakistanis use the airline they should ensure the airline is accommodating them properly.

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 think if i find different options I’ll travel with it but not with air India they never loaded the luggage’s and they announce the luggage’s will be arriving on belt number 5 when all passengers reach to the belt we find they haven’t loaded the luggage’s

Flight was cancelled by air India. There was no explanation provided why the flight was cancelled. Found out that the flight was cancelled because the Iran air space was closed. Meanwhile, all other flights passing through that region were operating without issues. When asked to refund money for the tickets, being told that “ As checked, we wish to share that Flight AI 116 on 15 January 2026 from New York to Mumbai was cancelled due to Iran airspace closure, which were beyond the airline’s control. While such events can disrupt travel plans, we appreciate your understanding and patience. Our team remains committed to ensuring the safety and comfort of all passengers and takes all necessary measures to minimize any issues. However, we must inform you that compensation is not applicable under these extraordinary circumstances, in accordance with the relevant regulations.” Completed unacceptable and unprofessional behavior!

Unnecessary delays & Gate changes, so much inconvenience after 15-16 hours flight

Very bad experience luggage never made to destination no help form airlines staff aircraft was old crappy forts staff service bad airlines staff

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

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

only passenger seats are too much narrow. It’s not comfortable otherwise it’s good. Seats are very important because it’s main in Travel

Mumbai to New York was not comfortable as I was given different sits in hat what I paid for

This was a bery good experience as it was a newer plane . AI older plane bussiness class is bad .

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.
