Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

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

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Transfer at CDG to connecting KLM flight to Amsterdam was a NIGHTMARE. LONG WALKWAYS, NO MOVING WALKWAYS, POOR signage, Have to take a train & No staff visible to help navigate the maze. AVOID TRANSFER AT CDG AT ALL COST.

Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

I tried to upgrade to premium economy anis seat online during the checkin process. The payment didn’t work due to a technical glitch on KLM’s website. I wasn’t able to change my seat unless I called Amsterdam. Since I was in Canada and there’s a time difference this wasn’t practical. So when I arrived early to Ottawa airport my seat wasn’t available and I could only get a middle seat in premium economy which isn’t great. These middle seats are priced at the same rate as an aisle seat which makes no sense.

The food & entertainment really stood out in terms of quality. The nasi goreng & chicken satay were absolutely delicious. It’s great that KLM feature international cuisine.

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

I took this flight to be able to fly with Swiss instead of Air Canada from Geneva.. The AC planes have a better outfit in Business class than Swiss, but the service aboard Swiss is really best, first-class, as is the food and beverages. Though using the same plane model (A330-300), the interior setup of the cabin starts to show its age, but IMO the planes are better serviced by Swiss than AC. I had in my recent trips with AC way too many technical problems that led to delays or even complete cancellation of my flight.. Their fleet is aging (average 20+ years) and the maintenance has taken a toll compared to years ago. Cutting costs in every corner has to be paid sometime by someone, and it's the travelers at the end that pays for it. Unfortunately for me, flying directly to Zurich puts a much longer after-fly trip on me than Geneva.. so I might go back to direct flight YUL-GVA, even if I don't like flying with AC.

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.

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

I like how professional, fast and good the whole experience was.

Crammed like sardines into the middle of the middle 4 seat row for an 11 hour flight was a terrible experience. No attempt made to help passengers sleep by dimming lights or shutting window shades. Small mediocre meals. Not enough good movies/TV options. Hopefully we will never have to do this again.

The plane was good - on time! But can the stewardesses smile or actually be nice - not to bark the commands

This time, I traveled in the economy, and it was surprisingly better than the eco-premium (food, comfort, and crew were noticeably worse in premium!)

I have no complaints. The crew was attentive, pleasant and heloful

Ghe issue was with the delay caused by the late boarding. We had to run to catch our next flight, barely made it and then our luggage didn t arrive with us. Really bad organizing.

Crew was wonderful, snacks were so good and quite a variety for free, food was mediocre, big selection of movies and they kept lavatories pretty clean throughout the flight

Flight was packed. This was a very uncomfortable experience. Boarding process could be explained better. Despite recommending a window seat when travelling with a pet in the cabin, the seat in front of me had less space than the center and aisle seats. For Premium Economy, the seats were crammed with minimal legroom. I hate to think what Regular Economy was like. The cabin crew missed me at first when handing out meals. When my meal eventually came, there were no utensils. I'd originally booked to fly Business Class; those seats didn't look that great either.

First time and I enjoyed the trip…. Will fly again soon 🔜

Delayed flight because other plane was occupying the gate for longer than expected. Once we boarded the plane had to wait 1 hour before taking off. We. Almost lost our connection flight and the baggage didn’t make it. We had to wait two days to receive our luggage. Hope they improve the timing or work with the airport to get better service.

I’m still missing my bags. I’m soo frustrated

TAP boarding gate agents singled out Group A line to gate check all carry on bags …. Supposedly because of lack on bin space. BUT ALL OTHERS WERE PERMITTED WITH CARRY ON BAGS. Additionally so many passengers entering the plane after us were permitted carry on bags. And when the plane was fully loaded, there was a number of open spaces in the overhead bins. I WILL SEARCH OTHER OPTIONS BEFORE FLYING TAP AGAIN

Boarding went fast. Lisbon's gates are too small for the flights they serve.

Baggage check in was very slow. No sign that the check in was TAP until the station opened. Understaffed and overworked team.

Great pilot, textbook landing in madeira. Everything else, from booking to checkin, plane quality, seat amenities, crew engagement, and overall experience were significantly below standard. I WOULD NOT FLY TAP IF THERE IS ANY OTHER OPTION.

Our flight was canceled for a reason that suggests gross mismanagement. We were re-booked for a flight to a different airport.
