I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

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.

You should not have to pay for WiFi in business class

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

They only had vegetarian food left on the flight which I wasn’t happy about. I didn’t get any food to eat at all.

My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.

The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

Much better than the major US Carriers especially in Biz Class.

I wish that the meal included a vegetable or even a salad instead of couscous! Why serve chicken with rice AND couscous? Service was good overall though a bit lacking in friendliness. Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!

It was not Air France but Air Europa. But confusion over our checked luggage. Whether it was checked all the way to Tenerife or not. It was not. Had to line up again in Departures. At least our Sky Priority was honoured. Flight was fine.

My wife and I had a row to ourselves after moving seats. There were no TVs and you had to buy food. So we did nothing but had a quick nap. Flight was fine.

Georgian Airways check in staff initially denied us, because they thought passengers required transit visas to transfer on connecting flights. This required 70 minutes for them to call multiple people to confirm how transfers worked. They did not apologize once accepting our check in. Onboard, the four hour flight gave stale bread with spam slices as lunch. The only included drinks were still or sparkling water.

I did not get my baggage at my final destination..poor coordination with connecting flights with partner airlines (Saudi airways). Also the food was very mediocre.

Not a good one this time. The absence of internet without any information/notification ahead was really the unacceptable part. Also this new A350-900 has a serious legroom challenge for economy seats. It’s more like a medium-haul flight legroom configuration.

Not great , just ok . I expected better food but it did not deliver . Flight staff was ok . The guy at the drop off bag counter was the only saving grace in this whole trip . He was pleasant, friendly and very helpful . You couldn’t ask for a better assistance from him .

This was my first time flying Air Canada. My first flight was delayed and then cancelled due to maintenance issues. They kept us informed and put me up in a nice hotel along with 2 food vouchers for my flight the next day. I understand things happen and they took care of the problem very well.I also like the fact that they don't charge for your first checked bag. The food was also hot, fresh and good.

From my experience, I see there is room for a greater mixture of cultures, for example, a mix of the nationality of cabin crews, food, music, food, etc.

Boarding was challenging as we had to use the stairs from the tarmac. Stairs are okay but a roller bag makes it challenging.

on time quick service but food so so and seats very small. no leg room. I think passengers should not be bringing so large carry on suitcases and should have free check in. Then boarding and unloading would be faster

After nearly nine years without traveling, my son and I decided to take our first flight, and we chose Air Canada and I’m so glad we did! From start to finish, our experience was nothing short of amazing. The flight itself was smooth, comfortable, and truly enjoyable. The staff were warm, professional, and went above and beyond to make us feel at ease. But what really stood out for me was the luggage tracking feature. Knowing that my bag was scanned onto the same flight I was on gave me such peace of mind. It’s little details like this that make all the difference, especially after not traveling for so long. This trip was incredibly special for us, and Air Canada made it even more memorable. Thank you for such a fantastic experience I wouldn’t hesitate to fly with you again!

Smooth on time flight with standard AC service. As usual food options awful. Wish airlines could offer better quality food services

Boarding was a disaster one person checking in 200 people took 25 min to check in zone 1&2.

Excellent bit seats are still a little too small and there's that $75 baggage charge.

Put first the requirement visible of the eta visa for no have problem in the airport at last time hour. Thak you.

No entertainment what’s so ever so you may want to prepare yourself. Our flight was delayed.

Awful. The flight wasn't actually operated by Iberia, but by American Airlines. I was unable to get my boarding pass and as a result missed my connecting flight.

The seats were way too crowded. Just because I do not have the luxury of a suite, does not mean that I want to fly from Austin to London scrunched between two people and the seat in front of me in my face. Ridiculous. I should have flown with Turkish Airlines...

Flight from Costa Rica to Madrid was excellent. Good food and service. The flight from Madrid to Brussels was very poor . No food , no entertainment, no usb … Total package was quite expensive so you should give same service on the second flight

Paid for “extra room” selected seat. Wasn’t a benefit. Also was in aisle and was bumped almost every time attendants walked down aisle. Should have saved the assigned seat money and let them select.

Couldn’t keep my luggage and had no choice. Ground staff didn’t even bother to explain why.

very good all round. staff, food, entertainment, punctuality all very good

The cabin crew were great very helpful and accommodating. We had a fellow passenger throw up next to us. The flight crew did an amazing job cleaning up and reseating us. We did question as to if he should have been let on the flight as his condition was likely self imposed.

A 13 hour flight with no food apart from what they offered from a menu you had to pay for. On top of that, there were no blankets, so during the flight when the cabin temperature dropped, everyone was very cold. Neither of these things were highlighted at the time of booking. This is the worst long-haul flight I’ve ever encountered.

online check-in was horrible and didn't work either way

The airline refused to board me because I showed up only 50 minutes prior to departure time, despite the fact that shortly before that, when I arrived at the airport still in time, they changed the terminal and I had to take a bus that took 20 minutes. Keep in mind that for some maintenance error I could not check in online like I usually do. Personnel at the airport was unable to let me in, customer care was beyond useless, the original airline operator (Iberia) was as useless as a toilet paper roll core in time of a wipe and all this uselessness made me waste my ticket, my reservations, my long time parking, food and most of all the joy of being with my family for the new year after working my bottom off even at Christmas. Am I happy? Come and ask me in person!

Boarding was delayed and we had to get on buses to plane so group # didn't matter. No food or drinks served gratis. Seats were small, knees smashed into the seat ahead, didn't recline. Crew was excellent though.

The flight from Seattle was delayed, which made me miss my connection to Florence. I was re-booked NINE HOURS LATER!!! That’s basically a vacation day lost. British Airways needs to partner with other airlines when possible to get a more realistic travel time, if delays occur. I realize there aren’t many flights to Florence from London, so I would book differently were I to return. The actual flight from Seattle was very comfortable and the crew was great, no faults there. I enjoy British Airways, this was an anomaly.

Our original booking with Kayak -our first experience -was exactly what we wanted and worked well. Updates were friendly and reassuring as were the contacts with UnderPricer so a big win-win. We learned a lot on your reliability and will definitely put you on our organisational list for the future.

The crew could not have been more helpful, my meal was excellent, I slept peacefully until right before landing, and the BA lounge was a godsend. The only negative I encountered was the coffee both on the plane and in the lounge. Not to my taste but that’s a personal preference.

Plane and seats ok. Dinners going and coming back were not fantastic. Breakfast from Seattle to London fine with bagel, cheese and fried egg. Second meal on London to Seattle not my favorite of kind of pizza sauce in a pastry. Came with water about three different times on each of my long flights. Staff on all very friendly and helpful.

I don’t understand why a reputable airline like BA would delegate their London flights to AA. Makes no sense to me, as most domestic carriers do such a poor job these days. Terminal 3 at LHR is a total dump

We ordered kids meals - which were not kid friendly at all! (the breakfast that is - scrambled eggs on a bed of spinach and asparagus?)

Uncomfortable seats. Crazy seat assignments separating families when they could easily have put them together. Good communication from pilot about arrival time after delay in departure. Toilet ran out of water in sink. Snack box poor for flight of this length.

The bed in Club class was not very comfortable, everything else was good.

Cancelled flight minutes before boarding. Rescheduled flight was two days later
