It was really nice experience by flying this klm flight.I personally recommend everyone to please try this klm flight

It was really nice journey i personally recommend klm flight

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

I’m grateful for the KLM Air France shuttle bus service to Ottawa. However due to construction and other issues related to the chaotic Uber pickup system at YUL, it’s a challenge to find the Kelios bus service to Ottawa. The signs are not clear or even available. No staff to guide passengers. It’s a stressful experience.

Terrible last row seats many seats available but no offer to move to better seat

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

My seat 3G did not go down fully and the buttons were not working properly

Food has been disappointing in both legs of flight to india

Great staff great experience, made a 2 hour delay very bearable

Great staff, great experience, made a 2 hour delay very bearable

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Great crew - old style upper class seats on the older fleet now feels dated

Nothing I like, I missed this connection b/c of an earlier flight delay. I had to stay one more night and I paid out my own pocket. LATAM failed to send me to a safe and decent hotel.

Apart of Sky miles delta. And they go everywhere in Brazil

We were not allowed to carry a bottle of water onto the 8 hour flight.

There was a mechanical issue with the plane that they had to work on before we could take off. That's fine, by all means, PLEASE make sure the mechanics are functioning properly. What was a problem was the fact that we sat on the tarmac for 4.5 hours without moving, without letting us off the plane, and without climate control and air running through the plane. There was no explanation as to what was going on; they just kept promising that it would be "15 minutes, then we are on our way." At one point, they even switched the entire crew out and told everyone we just needed to wait for new employees to show up. Then, as the 4 hours were not moving, an hour before the full refund, they made a big show about "the flight starting and the doors are locked, so you have to sit down." We didn't move for another 40 minutes; they were just trying to skirt around legalities that entitled us to restitution. When the flight finally was underway, the plane was gigantic but cramped in design, my entertainment screen kept freezing and glitching, and subtitles didn't work, and the crew was passive-aggressive. Terrible flight.

We traveled with two young children, and it was not possible for our family to be seated together. No one offered help or assistance to organize seating so we could sit with our kids. In the end, we managed to find two seats in Economy so I could at least sit with one of them, even though I had originally paid for Comfort+. In summary, I had to downgrade my seat just to be able to sit with one of my children, which was very disappointing

Latam may be the worst airline in the world, far worse than even the lowest of low cost airlines in the USA. I wasted hours trying to PAY THEM TO CHECK A BAG! Then they misled me at the terminal, sent me through the wrong security line, the list goes on and on... Just absolutely terrible in every way. Avoid at all costs.

Poor, the airline was not able to help me move flights.

The way the Pilot made all announcements, specially the way he congratulated the entire crew as the best team ever, making a comment that due to them they were able to shorter the delay to the destination. Amazing flight .

The plane broke down at the Lima stopover and they offered to put me on a flight the be t day but I had to be back in LA that morning and so I had to buy another ticket from Avianca and United for $2k I asked LATAM for compensation and received none. Very bad experience

Just to drop my already labeled bag it took 50 minutes inline. Completely disappointed with Latam operation at GRU

No difference between business class and normal same seat everything same, waste of money

Kayak let me choose these flights on TAP but then after 2 months, cancelled my flights because they didn't think 90 minutes was enough time for the connection. I notice that neither flight was actually cancelled. Just my reservation. Why let me go through all of that effort to find the right flights for us, only to cancel it from underneath us 2 months later leaving us scrambling to find an alternative?

They allowed me to book the flight, which took quite an effort to find the best option for us, and then 2 months later, cancelled it because they didn't think 90 minutes was enough time to get between connections. Why let me book the flight in the first place? I am somewhat disappointed in Kayak and will be choosing other options in the future

Should really consider a better, smother boarding. Stood in tunnel for 20 plus minutes. Should start from back passengers of plane. Not front.

It was a good experience overall. We were however delayed by over 3 hours due to a security issue with one of the passengers inadvertently leaving a power bank in a luggage she was using as carrying on but then had to be moved int check in due to spacing issues. The airline staff had requested that she checked her bags in, but should have reminded her about removing all hazardous material like her power bank. When she eventually remembered as we were on the plane, we had to turn back and go through security all over again. Hence delaying our takeoff. The incident could have been prevented if staff reminded these passengers to remove their power banks.

We upgraded to business class. Nice seat with lots of room but otherwise not impressive.

this flight was awful from pre-boarding to on the plane. There needs to be more coordination between TAP and My Way. We were in first class and I am handicapped. BY the time we got on the plane there was no place for our baggage and the crew did not handle the situation well. They gave us an argument and said that we'd have to have it checked. Then, after I complained they moved some people's bags to put our small carry ons several seats back of our seats which were in Row 4.

Late. Lack of updates. Rude hostesses. Terrible food. Lack of headphones.

Negative. Food was awful, seat broken, flight was late, baggage lost and damaged

The value is there, but the layovers in Lisbon were not great. The passport control was so bad that a 2 hour layover became very tight and on the return the Terminal was barebones which made it a long 3 hours.

Not to bad but it was hard changing my seat

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

The flight was ok but chargers did not work and the speakers in the back of the cabin did not either. But I am writing because the crew was really, really rude and not only rude but had the curtains always closed, forgot to clear our trays, the bathrooms were filthy and trash was building out, and one of the attendants even had her EARBUDS on while in the cabin. From movement it seemed like she was listening to music, so not even the safety aspect was there. My neighbor s English is not good and they were very dismissive of her. when we deplaned the crew in the back was just chatting with one another and the first class attendant was briefly and said goodnight. It is nice that a crew gets along so well, but they did not take care of passengers at all. They rushed through all the services and otherwise did not go through the cabin to offer water or anything else. i had the feeling of being unwelcome at a party. I am not a grumpy traveller but I thought you really needed to know. Thank you, Carin

The plane was late (as was my flight out from Birmingham the day before)

This is one of the best flights i had. Good boarding, good seats , good food, and nuce stuff and clean toilets I took the Tourist upgrade and indianischer food , the best.

The flight was delayed by an hour. Made the connection uncomfortably tight.

Very old plan, bad cabin layout and seats, entertainment system would get 95% through a film and then crash and reboot. I wont be using Lufthansa after I return back home, would rather pau more for a better flight arramgement.

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.
