Klm start boarding while somw air issue in the plan

The service was great. However the lounge only gets passing grade

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

You should not have to pay for WiFi in business class

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Each flight we took was late with little or no updates or information.

Swiss airline do not allow online check-in before 24 hrs, this is very inconvenient to us. I tried many ways such as booking code(6 numbers) or 13 booking numbers , neither of them work, Lufthansa is better which allow us to check in even before 30 hrs, so we can assign our seats( not many people want spend extra money to assign seats on top of airfare which is already spent.)

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

It was great. My seat was comfortable. The bathrooms were clean . The service was superb . I travel a lot and I have been in 64 counties. I wish I could fly first class, even though I could , but I prefer to budget my yearly travelling expense on actual visiting , not on flight. Anyway, my point is that your economy was far much better than other airlines as good as Air France. The flight attendants and all crew were polite and very helpful and respectful. Thank you for making my long trip tolerable.

My luggage did not make the connection and 4 days later I still have not received it.

We're talking about a short-haul in-country flight.. there is no confort, no food, just the bottle of water. The seats are squeezed like hell and I was in the back-end of the plane, with one spare row left for the crew and to store excess bags that could not fit in the overhead bin.. Speaking of carry-on, some passengers should be better screened as their bags were simply too big to fit in the overhead bins.. ! How can this happen, and it was an A310, with 2 columns of 3-seater rows.. There is a pseudo-Business class, which is simply a section in the front of the plane where the same seats are occupied only 2 out of 3, on each side, leaving more rooms for the passengers and their bags. That's it.

We are glinting with united , but over all very disappointed

It is a good airlines, very professional very good food. I wish they offered free luggage is the only thing.

Terrible plane small airbus good for a 1 hr trip I booked business as it is. A night flight and 4hrs trip it was an ordinary economy seat with no one next to me what a joke what a stupid decision to buy business

For the price of the ticket it's probably the best service in the world

I’ve flown with Qatar multiple times and the service has always been great. Very professional, organized, the food is delicious and plentiful, tons of entertainment.

All the crew members were too slow and rude. Most of the times the registers were empty, while hundreds of customers were waiting in line, and it was impossible to get a supervisor. Despite being in line on time, I missed my freight, plus a some customers who were ahead and behind me.

I recently travelled with Qatar Airways from Doha to Dulles in the QSuite, and the experience was nothing short of exceptional. The QSuite truly feels like a First-Class experience, with its luxurious design, privacy, and comfort. The cabin crew, especially the lady in charge of the cabin, was remarkable—professional, attentive, and genuinely kind. The food was excellent, and the comfort of the seat was absolutely first-class, making the journey smooth and enjoyable. While the in-flight experience was outstanding, I have a few points of feedback. Firstly, the content available in the in-flight entertainment system could be expanded and upgraded to include a more diverse and updated collection. This would elevate the entertainment experience to match the premium standards of the QSuite. Secondly, regarding the Wi-Fi service: while QSuite passengers receive one hour of complimentary Wi-Fi, any additional usage requires a fee of USD 10. Considering the premium pricing of QSuite, it would be more fitting to include unlimited Wi-Fi as part of the experience, further enhancing the luxury offered to passengers. Lastly, I must highlight an issue with luggage handling. Unfortunately, my luggage did not make it through the transit, which was disappointing. While the ground crew assured me that it would be delivered to my home on the same day as it was arriving on the next flight, this promise was not fulfilled, and the delay added unnecessary inconvenience to an otherwise excellent experience. Overall, the QSuite experience was exceptional, but addressing these areas would further solidify Qatar Airways’ position as a leader in luxury air travel.

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

Our male flight attendant was top notch - wish I could remember his name. Boarding is never fun when I have to ride the shuttle to the middle of the tarmac and pull my carry on bags up the stairs to my seat. My knees are banged up and my shoulders give me pain, so the flight started off poorly. The seat leg rests don’t recline completely so that makes is difficult if not dangerous to get in and out of the middle seats. The entertainment system touch screens prevented one from seeing the options. They are old and the software needs to be updated. I was on six planes in the last two weeks and able to see the flight progress without any stress. Couldn’t watch anything else. I do like Qatar Airways, just not a fan of a few things.

The overall flight experience between Doha and Kolkata was satisfactory. The staff onboard were notably engaged, responsive, and enthusiastic, providing a level of service that stood out, especially when compared to the less attentive crew on the earlier leg from Heathrow to Doha. Their eagerness to assist made the journey more pleasant. Additionally, the time spent at the Silver Lounge in Doha contributed positively to the experience. The lounge offered a comfortable and relaxing environment, with adequate amenities and attentive staff. Overall, both the flight and the lounge experience in Doha met expectations, making for a smooth and satisfactory travel experience.

Doha airport is huge , takes long time to reach gate .

Moved seats, didn't accommodate requests to change seats even though other seats were available.

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.

Flight was fine overall. What you would expect from economy seats. I did appreciate the amenities (eyemask, earplugs, small toothbrush and toothpaste, thin socks).

This flight was in the air when the national power outage happened on 28 April 2025 in Spain and Portugal. As a result Lisbon airport was closed and the flight was diverted to Porto. There were no phones, internet or ATMs working and the Turkish Airlines ground crew in Porto were trying to find alternative transport to Lisbon (by bus). This did not materialise until late in the evening. The Turkish Airlines ground crew suggested that passengers may find their own way of getting to Lisbon. That in itself is a failure of Turkish Airlines, but understandable as there were no means of communication. The Turkish Airlines ground crew also said that any expenses insured for travel to Lisbon will be refunded by the Airline through their website. Unfortunately, I could find no way to travel back to Lisbon other than to hitch hike with an Uber driver. Because no systems were available and no credit card payment possible I paid the driver 140 Euros in cash with no receipt as systems were down. I arrived at my Lisbon hotel at 23:30 (flight was scheduled to land at 12:30). Upon contacting Turkish Airlines for compensation they are not willing to do anything as I do not have an invoice for my expenses. They do not even consider the 10 hours of delay and inactivity on their part as a reason to provide any sort of curtesy towards me. I find their behaviour appalling.

Very nice and friendly crew. Boarding system can be improved.

Food is getting worse. They use to be different than other airlines. Their economy classes food sucks. Stuff was very helpful.

Not worth pay business classs and get service economy class

A fairly standard 2/2 configuration. Boeing 787-9 is modern but the amenities chosen by Turkish for their seats are slightly limited - no in-seat charging, for example. Otherwise, a good flight.

A great airline, no complaints at all. My experience with Cheap Tickets was very disappointing however. Two hours after purchasing the flight they called to tell me that the ticket price had gone up. I’ve never heard of such a thing. That is called false advertising; I will never use this ticketing service again and will warn all friends to never use it.

Professional & courteous cabin crew. Food was very good even in economy class

Terrible boarding experience, with an incomprehensible assignment of priorities. “Fast track” was the slowest. Poor system planning.

Internet connection was very weak, did not connect at all. Seat comfort was poor, buttons didn't work properly. Overall not impressed in business class.

Food excellent Bathrooms improve cleanliness needed Staff fairly well attentive Entertainment fair Seats lie flat worked well

Flight was 1.5 hours late to depart so changed flights to Swiss Air.

I wasn’t allowed to board with my children. I was charged outrageous costs for basic carry on size luggage. The entertainment screens were outdated and not user friendly.

I enjoyed my flight back with Lufthansa because the food was good, and the flight attendants were nice and helped you when you asked a question. The flight attendants always came around and asked if you needed anything which I liked a lot.

No entertainment since it was a 3 hr flight. Good leg room for economy.

Very good. I thought the choice of Mediterranean food such as falafel for lunch was very thoughtful considering we were flying to Cairo.

Seats were extremely hard and uncomfortable. as well as very narrow even though I paid an extra $230 for upgraded preferred seats. Very disappointed in the downtrend of Lufthansa and United Airlines.

Food service was good. Aircraft was old and needed upgrade such as seats. Flight was delayed about 1 hour.

The flight was cold, no enough blanket and the crew said that they can’t change it. I got very sick in the flight . Most of the kids were coughing.

Both my flight to Germany and my flight from Germany to the USA were delayed which caused me to miss my connection and additional stress. I had to stay overnight in Chicago, compensated by the airline. All very frustrating. We sat in the runway in Germany for over an hour? Which was never explained and caused the additional day of travel.

Before the flight I received an email from LH that our seat were changed to other comparable seats. At boarding however we found our reassigned “comparable” seats were directly by the toilet. They sure were no “comparable “ seats and we were quite disappointed!
