I can’t even the whole trip was a catastrophe

2.0 MediocreAnonymous, Jul 2025BOS - DBV

I can’t even the whole trip was a catastrophe

Poor. Seats uncomfortable. No leg room. Hot and humid the whole trip. Food and staffs were ok.

I purchased a one way business class ticket from Geneva to Miami but the check in agent said I had an economy ticket and later upgraded to business class. This was not the case, I had a single business class transaction. I was forced to pay for my second checked bag. I am unsure of why this happened. But I won’t use Kayak again for business class tickets.

The seats were so close together, when the man in front of me put his seat back, the screen in front of me was 9 inches from my face. There is no way to lean forward if I needed to pick something up. It was pretty uncomfortable for a ten hour flight. I was very surprised.

The food was good. Most the staff was pleasant. The flight would be drastically improved with WiFi on a long international flight.

All the flight to USA were arranged to E terminal whereas from Dubrovnik arriving on Zurich is on A80, have to walk all the way from A to E, even need transfer bus , for short transfer time like in an hour, we have to work fast, as soon as arrived at E, it is about time to boarding, pretty tight schedule, I hope Zurich airport can make some rearrangement so that transfer people do not have to walk long way. For short transfer time people, such as 50 min, this is even impossible if still like this.

...as stated previously, red tape should be shorted by Swiss in terms of generating refunds...

When I needed to get my bag off of the plane so that I could take a train because the connection was 4 hours later, they took 2 hours to take my bag off making me take the train and miss my flight simultaneously. The seat size on the plane is too small for an average aged woman let alone a middle-aged man. It's unacceptable and I will not fly Boeing again.

The cushion of the seats are old and very thin. The food can be more tasty or come with salt packages

The staff were nice people, the food was very cheap, one of the meal was a sandwich or nothing, I couldn't buy any food, mind expensive duty free WAS available right away. 🤒

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

The seat and leg room was not good. The food and beverage service was good.

For economy, it was very good. Staff was great, they even let some of us change seats for more leg room... Put an empty seat between us which was fantastic for a 12hr flight. Onboard entertainment was excellent, I think over 200 choices of movies/tv/etc The bad was the barely/nonfunctional wifi that cost either $16.99 or 1700 miles (full flight). It was atrocious... Definitely the worst of the last 3 long haul major airlines I was on the last few months.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

Overall, it was a good experience. Boarding was good and there was plenty of overhead bin space for everyone’s carryons (even when we boarded toward the end). Only improvement would be to offer trash service more regularly.

David went above and beyond to make our flight the best that it could be

No food service almost missed because of first flight delays

The economy seat was so uncomfortable, had not enough leg room for 13 hours flight, front seat basket was broken and couldn’t hold anything, food quality was horrible( we got food poisoned ) we charged for logged which used to be free. We paid too much for this flight and very disappointed. Turkish air line better to make satisfy and respect people instead of find different way to scam people.

This is really the rating of two flights. JFK to IST then IST to NQZ. New York to Istanbul was good. Good crew and all positives. The flight to Astana was so bad that brought it all down. Crew was nonexistent above the minimum, seats were cramped, and it was hot on the plane. Turkish Airlines seems to be slipping down to US based carriers level.

The 2 agents on the check in counter were super nice , helpful and very polite. Boarding was like a 1 2 3, I would recommend Turkish airlines for your next trip.

Everything was very good, except that the plane was an hour and a half late

flight with heavy turbulence old boeing 777 rest wasnt clean dashboard doesn’t work

Light and recline did not work on my seat. Very uncomfortable and could not read in the dark

Bad experience; they are not good anymore. They charge too much for luggage seat are so uncomfortable, Flight delays which may miss your next flight, they don’t care if you miss the flight or not. Zero customer services for front desk representatives Istanbul's airport I’m not using this airline any more.

I’ve been traveling for 20 years. I tried Turkish airline for the first time horrible horrible service and it would be my last time even if I get offer for a free ticket, I will not accept it. They have races and the worst Flight attendant

It wasn't good. I didn’t understand. They changed 320 dollars for 2 luggage. My ticket was regular and I paid almost 1200.00 dollars. Why they did charge? I want my money back.. thanks Yılmaz polat

Very punctual, the onboard staff was friendly and correct, the flight was fortunately very calm, the toilets were clean, in short, an excellent experience Thanks

Both flights are delayed so I rate the whole experience as mediocre.

I booked my flight months ago, and checked-in online about 12 hours before the flight. I received an email confirmation of check-in. I had no subsequent communication from Air Canada after my original booking. After arriving at the airport three hours before the flight, as instructed, I waited 90 minutes for an agent to appear to check my bag. I was informed that my flight had been canceled many weeks before, and that flight was no longer being run!! I showed a copy of my check-in confirmation, but no explanation could be found. I was placed on standby for the next flight and the connection. Luckily, those flights were not full and I arrived at my destination. I double checked my email, but I received no update about the flight from Air Canada until the day of the flight.

I had a good experience. I liked being informed about the status of my luggage

Very bad service the way back we was on the way for r two days very bad condition and waiting for luggage till now

I was forcefully re-routed to another destination and was delayed a total of 8hours. I have still not received my bags, no one is taking responsibility. The agents at the airport lied to me that I will get to my destination same time as my previous flight where I was forcefully re-routed from.

Flight was delayed by 1.5hrs. Once inside, people had their small handbags on the storage. The crew (male guy) was not helpful in making some space in the storage. Instead, he asked few bags to be checked-in and it was not a great experience. No attempt to help but just followed the things with a straight face. People had their literally small bags and he wouldnt not move from one storage to another even if there was space and would not let us do i as well. Once flight was on, they ran out of Orange juice, really running out of orange juice when the temp were 32.degrees outside. didnt made the sense. Onasking for a extra snack, he made a face as if he was giving me out of his pocket. if the flight was delayed, there could have an attempt to provide something extra incase people did asked.

Our flight was canceled at the last minute. Someone on the flight said the exact same thing happened to her the day before. I will say they helped us book a flight on another airline so that we could still make our vacation with little delay.

United had no (zero) record of our flight. It took over an hour of us standing in line with surly employee while others waited to get resolved. I have never experienced such poor service and poor empathy.

We had a very long delay. First the inbound flight took a while, then maintenance, they “fixed it” to then do boarding and leave the gate, and waste a lot of time to have to go back to the gate and eventually deplane. Had to wait for a new aircraft, wait for a gate, and do the whole thing again. Instead of leaving at 9:50am we left until past 1. I could’ve not woken up at 5am, or spend some more time with my family if they gave more grace period of time between flights to give some time in case of any issues. But they have to make all and every dollar possible

Aircraft had technical issues. After 3 hours of trying to resolve, flight was cancelled. Was booked on a flight leaving 12 hours after intended departure. Now on 4 flights instead of 2 and a day late to my destination.

Our flight was delayed for over an hour due to weather, and it had already been a long travel day. However, the crew was calm and compassionate, listening to every complaint with genuine concern. They got us home safely without incident, in spite of all of the obstacles. I’m grateful.

Hate their old flights, boatding, food and services. Very poor quality

Insulting. Lufthansa flight from Munich to EWR had us getting our luggage when we were told in Florence that it would follow us to Indianapolis. It did not. Then very slow security in EWR caused me and three other passengers from Lufthansa flight from Munich to miss the boarding closure. Behind me were two elderly grandparents and their ten year old grandson. We were all refused entry on a plane to Indy that was still at the gate. The doors had not even closed inside the terminal yet. No apologies or compensation offered. Not even a meal voucher let alone a free hotel stay for our inconvenience. I m not sure what the other three passengers behind me did ( they were elderly with a grandson, recall), but I stated 12 hours overnight in a chilly EWR airport until next flight to Indy at 850 next morning.

The food could be better, more snacks. And have some plugs to chargue the phone.

The pasta in the evening meal was tasteless. Otherwise, the flight was okay.

Everything was really great just The aircraft was too old and sounded it will break during takeoff

Seating was average for a first class seat. It very modern. I expected better.

Flight was a little late. The crew was courteous, food ok

Bad! Disaster!! The LH419 was cancelled after 4 hrs on board with no AC and no toilets

Poor food on flight between Toronto and Stockholm Airport Toronto too crowded
