More facilities to transport to the gates......felt too much walking distance

More facilities to transport to the gates......felt too much walking distance

From Montreal to Doha , we habe two complaints : 1) They want to charge for Seat Selection, claiming that the Class of ticket bought on Kayak did not cover seat selection. It such a penny pinching rule, I told them, since we paid almost $20,000 our 3 tickets , that rule should never exist. Also I reserved my tickets so many months ahead, I expected they will naturally put the family together or move somebody else to keep our family seating together. I filed a complaint, and NOBODY ANSWERED. 2) In Montreal, Qatar has an arrangement with the National Bank Lounge. It was so overcrowded and the Lounge is so bad in terms of service and food, amenities etc... The WORST lounge . Why Qatar not have another arrangement their Business Class clients in Montreal. The Air France KLM Lounger is better, the Air Canada Lounge is better. Qatar should send somebody to take a look ! Joseph Chung

They shld improve and provide a lunch or dinner in an international leg

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

Wore experience due to delay and took me 3 days to reach my destination.

No separate queue for business class/platinum passengers. I had to stay in the long queue to board. I requested breakfast before landing, but the crew didn't offer, except a coffee with milk. No tea with milk was available. Had asked for cookies, but didn't receive them. The crew in the business class was not good in terms of service..

Polite and helpful crew. My son developed fever. Crew members came and gave him medication and also came and enquired about his health several times.

Very very bad.. more than 48 hr I didn’t received my baggage yet

There was not enough staff during boarding which had created big problems . Another thing once you enter gate area there’s no way to use bathroom and you have to be in that area 2 hours before boarding which is too much.

The staffs were very good and helpful especially since we were traveling with a toddler

Don’t use them on the IST-isb route, horrible service

It was a nightmare. I booked business class ticket from Ediburgh to Beirut via Istanbul to attend a funeral. I had a wonderful experience flying to Istanbul from Edinburgh. Then I could not get a boarding pass issued to Beirut. It seems that although they booked me and I had a reservation number, I had no seat allocated and the flight was full. I was asked to go from one desk to another and made to wait for 2 hours. I missed my flight as I did not have a seat assigned and it was full. The only option was to put me on the next flight, 6 hours later, for a fee of over $400. They said that was the best they can do to 'help me' and to 'take it or leave it'. Well, I was not about to be bullied; I stood my ground. I booked and paid premium for the journey, which was confirmed. The eventually accepted to not charge me extra and i waited a total of over 8 hours in the airport with no compensation. On top of my grief with the risk of missing the funeral service, I had to put up with their indifference and condescending attitude. They spoke about me in Turkish thinking I would not understand (I hold a British passport) in front of me. When they eventually handed my passport and boarding pass back to me, I showed them I was born in Istanbul and that I understood everything and said a condescending 'thank you' back to them in Turkish. You should have seen their faces. I said that consumers have rights and it is a shame that Turkish Airlines does not have good customer service to at least acknowledge and apologize for errors committed by the airline. Blaming the me, the client, for such an error and placing unreasonable ultimatums, rudeness and dismissiveness to be rid of me, particularly when I was vulnerable and visibly grieving was really shocking... The airline taints the city of Istanbul and the people of Türkiye. Such a shame.

Was not able to check in online, so had to stand in line for 90 minutes to get a boarding pass, and I had no luggage to check. Why not let people check in in advance on line? Or at a kiosk at the airport?

There was a Turkish Airlines employee sat in 16A in the row in front of us. We understood that she was a Turkish Airlines employee from her interaction with the cabin crew and the fact that she boarded business but was sitting in economy with us. What annoyed us was the extremely loud conversation she had for the majority of the 12 hour flight with two men, one of which was leaning over the chair in front of her. This was annoying as they were so loud that my wife and I could still hear them despite wearing our noise cancelling earphones. No intervention was taken by the cabin crew. Secondly, she ordered some extra meals from the crew, which we believe to have come from business class, for her male friends. Seeing this in economy is very disheartening. Lastly, one of her male friends pulled out an e-cigarette and was only mildly reprimanded by the cabin crew. Overall, we consider this behaviour completely inappropriate of a Turkish Airlines employee. Next time we will book with Emirites, I don’t think that their employees would be allowed to behave in this manner.

There was a Turkish Airlines employee sitting in front of us, we noticed from her conversations we witnessed with the cabin crew and the fact that she boarded business class. She was sat in 16A. Firstly she was talking loudly the majority of the flight with two other men, one of which was leaning over the seat in front of her. This was disturbing as they were talking loudly and we were not able to sleep. The 12 hour long flight turned into a nightmare, even the noise cancellation didn’t work for their chatter. Secondly she requested extra meals from the crew for her male friends. We believe the meals came from business class. They also took their e-cigarettes out and were caught the cabin crew, but no further action was taken. Sitting in economy and seeing this is extremely disheartening. Next time I will book Emirites, I don’t think their staff would be allowed to behave like this.

COmpared to my experience in the business class of other airlines the food variety and offerings were meager. They did not have any cookies or crackers for snacking! They were unable to offer some other items. This has never been my experience in other airlines.

Paying for reserved seats and never received the seats I paid for !! Just fake and a surprise out of their " box "

The flight departed on time and the staff was professional.

The crew was excellent, but the flight was a little delayed and the temperature on the plane was too warm.

Sadly, the plane was extremely old and uncomfortable. The entertainment system broke down completely. We couldn't even charge our phones. The seats were also very uncomfortable, with a very slim seat cushion. It must be the result of having 9 seats where there used to be 8.

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

Very good need to offer better choice of food for business

They should. Heck planes more often not when they are suppose to be leaving causing delays

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Great hospitality and service! Seats could always be cushioned better.

Excellent long haul experience really enjoyed using Dublin pre-immigration

Nice easy flight. Crew was very nice and of all the times I have bought a seat for my guitar - this was the easiest. They were prepared and no problems at all.

We were helped whenever needed and had a pleasant flight.

Air Canada from Edmonton to Toronto was disappointing but Lufthansa from Toronto to Frankfurt was excellent.

I'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

bad seats, meager food quantity. bread not fresh. Hollywood films lack entertainment.

Great flight. Left on time, not very crowded. Quiet and the right temperature.

Boarding is as always an issue. Slow and long boarding time.

Flight crew was ok but in terms of child-friendliness, no one beats KLM and even most US carriers are better. Economy class got smaller and smaller over the years but still better than AA or Delta. Food was pretty good and pre-boarding with our infant was available.

I paid a lot of money for seat selection and was miserable for flight duration

Le personnel attentionné et trilingue, la tranquillité du vol. Aucun aspect négatif

Delayed, took forever to get luggage out of the flight. Worst short flight within Europe we've had.

Ryanair is the worst airline in Europe and easily one of the worst in the planet

O voo atrasou um bom bocado A tripulação não era comunicativa,não fez vendas... Não abordava os passageiros... A 1°vez que me acontece tal coisa 🤷‍♀️

While this flight from Dublin to Venice boarded on time, its departure was delayed by about an hour because, apparently, there were no demonstration kits on board, and we couldn't depart until the safety demonstration was completed. We were informed that we were in danger of losing our delayed slot if Ryanair engineering didn't provide the kits 'soon', which would have resulted in an additional two-hour delay. Thankfully, we didn't incur that additional delay. It's not clear where the source of this problem lies but it needs to be addressed to ensure it does not recur for other flights in the future.

We each paid for 10kg checked in luggage. Flying out there were no issues sharing one case (20kg). Not so coming back. Additional £48 charge and unable to provide an explanation of why it was ok on one journey but not the other, or indeed what material difference it makes between 2x10kg cases vs 1x20kg case. Scam, and appalling from Ryanair.

Usual RyanAir flight but disembarking was poor, no rear steps. The Faro Airport required lots of up step and down steps, no elevator Getting through passport control took 50 minutes in the EU line

Flight was delayed due to weather so not much Ryanair could do about that - otherwise it was very efficient and smooth

I wouldn't like to fly with them anymore, I don't like their service, you can hardly take carry-on luggage because they charge you for everything, you can't ask for a glass of water, and the flight attendant tells you that they don't have any, that you have to Paying 3 euros for a bottle of water horrible, I don't recommend it, and they don't have anything low cost, because the plane ticket may not be expensive but what they charge you later for the rest, the flight becomes more expensive, it's the only airline that I don't like it so far, and I traveled a lot.

Boarding was chaotic, the gate changed 4 times and we took off 1 hour late

The flight was delayed by more then 5 hours and we lost our connecting flight. We had to purchase new connecting flights to our expense.

Kudos to the staff for their patience and professionalism. Next time, please stop serving alcohol to Romanian male passengers who are clearly not able to drink with measure. Appalling behavior.
