Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Empty seats next to me - wish it had been for a longer flight!!

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 on my previous leg, had to run to catch my flight. But that happens. Overall ok.

They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.

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.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

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.

Lounges are packed and very poor, food is really bad, for business class in an airline is well below expectations

Overall flight was ok. Flight attendant was receptive to assisting passengers with tight connections.

I liked that it was on time, however, the food was not good.

Flights were on time. Free Wifi on plane. Everything was well organized.

I will never fly ANA again. They lost one of my large pieces of checked luggage, the heaviest one with the most valuable items in it, and they said they will not send me an email unless they can't find it, even though the paper they gave me to track the status of my lost luggage requires a code from an email they are supposed to send me so I can do baggage tracing. They claim to be an international airline, but they also insist on calling a Japanese telephone number to confirm where to send the lost baggage if they find it. It is impossible to find an actual contact email address for customer support on their website, and their AI chatbot is unhelpful, directing you to a webpage that says it is for contact information but does not have any actual email addresses or phone numbers listed on it. My seat in economy did not recline at all, even though I was not sitting in an exit row nor the very back row. I had to sit in the fully upright position for over ten hours of international travel. Awful experience overall.

This trip did not start off well. The inbound flight was delayed about 20 minutes. Then, after initial onboarding, the passengers had to deplane due to a mechanical problem. That took about 30 minutes to fix and be cleared. Then, reboarding was chaotic. It took a long time to sort passengers and two passengers on standby were ticketed but there was no seat. So, they had to deplane. One of the flight crew was trying to help passengers figure out a place to put their carry-on bags and that took more time. In the end, our scheduled 10:30 am departure did not actually take off until about 12:05 pm CST. The flight itself was long but we got to Houston. Some passengers missed their connecting flights and had to rebook. Not the best of flights I've had.

Nothing also dont give to people that disgusting blanket and pilow.

Flight delayed. WiFi connectivity very poor if not existant. Last minute arrival forced me to run to catch my connection.

Delayed, toilets did not flush, pilot parked to far away from Gate

I just think it’s unfortunate that Airlines have completely abandoned the idea of serving any kind of decent or even real food on flights, not even on a four hour flight!? Those days are gone, I guess.

Entertainment and wifi were very sub-par - audio issues and no wifi

Disaster This is why I stick to delta You get what you pay for

Delayed our flight to accommodate another flight but didn’t make the decision to do so until we were supposed to board despite having all the same information hours prior. Arrived so delayed that we didn’t get a gate and had to deplane on the tarmac and get bussed to terminal in the rain after 1am. Arrived to the terminal and due to construction could not get a ride share - had to either take the air train to Howard beach or stand in line with 200 other people waiting for a taxi.

Well, its a hit or miss when boarding most of the time your employees just let everyone enter immediately In one bum rush. Then out of know where tell the passengers only let A can enter then b then c etc. So make a decision and stick to it. Do it by alphabet and have famn strick compliance. Let the public know. That makes easier on passengers.

The seats have so much room. They give great free snacks. Staff was so nice.

It was a pretty smooth flight, I tend to get mini anxiety attacks during flights, however, this time was pretty smooth and I was able to relax. The only thing, I was having issues to connect to the Flyfi internet. I was not able to connect at all, I turned off my phone a couple times and didnt work.

No included food for a 5 hour flight and the entertainment was only accessible if you had wired headphones (not provided). Otherwise though, great and smooth flying and customer service.

They initially informed us that the flight was delayed, but only after waiting an hour for updates. In any event, the flight was canceled, but the way it was handled was really poor and egregious. I feel they handled the situation of informing travelers very irresponsibly. I sat in a wheelchair at the airport for over four hours before finally being told that the flight was canceled.

Good. No issues except a slight delay. Crew came in late.

we were delayed because of some safety check that wasn't done or available

Same plane as RDU to LGA — internet not working. Pilot issue of some sort at end of prior flight - I was on same plane for my connection. Late/delayed —

Award tickets are some of the best... seats lack entertainment options.

On the return flight, arriving in Denver we sat on the tarmac in Denver for over 20 minutes.

Terrible planning. And even worse gate agents. Absolutely rude behavior.

We hoarded. Then we deplaned. Then we waited for 10 hours in the MSP airport due to a wheel misfunction. We understand safety but communication between crew and airport staff was horrible. When we did finally board, we were rushed on and because we were waiting for a “fresh” pilot and crew, we sat in a roasting plane with no A/C for an hour. My question is why was this flight not cancelled right away when they knew this would be a huge issue OR, why did AA not get a substitute plane, considering this was already a full flight? To me, this appears to be a complete breakdown in leadership and utter systems failure. The compensation for completely disrupting travel plans for hundreds, which we paid dearly for, was measly. While we appreciated the lodging for the night, $12 in meal vouchers isn’t going to sustain anyone for over 12 hours. “We apologize; our hands are tied” is no longer an acceptable explanation. We are so completely turned off by this experience and will definitely seek alternative avenues when we need to fly.

There was no inflight service. Once we landed we were delayed to find a gate for an hour and a half which was 1/2 the total time in the air.

Boarding delayed 20 minutes for no reason, no wifi, in flight entertainment, or snacks / waters?

The accessible bathroom should be visible to people in Economy class.

Generally good. Flight left on time and the seats are comfortable. Plenty of space in front if you in you choose a comfort plus seat, completely worth spending the extra money given the amount of hours the flight lasts. The food tastes good but I would say it’s a the amount is too little. The crew was friendly and efficient. There was a some turbulence at different points into the flight. American Airlines has good deals to NZ if you book with plenty of time before you plan on going.

Flight from CHI to PVD was delayed by over 20 hours.
