The flight was 45 mins late leaving, we sat without a/c for some of this, 2nd Meal was a slice of pizza. Movies were good.

As always, it’s a pleasure to travel with KLM. It is one of my favorite airlines.

Outstanding even though the 330 was one of the oldest in the fleet. The difference was the attentiveness and responsiveness of a really experienced flight attendant. For airline food great variety of interesting choices and good tastes supported by a good wine selection.

Brand new plane lots of room the snack was very flavourful and enjoyable

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

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.

Seats! The eternal problem in economy. They are like stones!!

Everything is good except the seats are tightened no rooms for the legs,

The flight crew was exceptionally friendly and helpful. Also the seats were comfortable and roomier than many other airlines.

The plane's pilots, including the captain himself, thanked me for the flight. I know it's just marketing, but it was really nice to see these people. It's a great idea. Airplane food is never "good," but the entire crew and flight organization were top-notch. I really liked Delta, and I think I've traveled all over the world, and that was something new for me. Maybe even the old planes, the B767, but next time I have a choice, Delta will be my first choice. Thank you, a satisfied passenger :)

Middle seats SUCK!!!! I paid more money than I should have because of your terrible site Kayak.com. I'll try to use your competitors going forward. I am so disappointed you would play off business class.com as business class seats

They lost my bag and I still haven’t received it yet

They lost my bag and I still have not received it

Communication on the delay, rebooking and how to get a hotel was poor. Mails, airport check-in and transfer desk said different things.

Safe and stable made me sleepy and I slept and dreamt 😂😂😂😂

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

Very good in business class but not so good in economy.

I need an upgrade to business class but they ask for bidding. Never mind...

Business class website is horrible I couldn’t even check in online never happened me before any other website

Long wait transit service wasn’t good also I couldn’t check in online never happened me before other websites

Very poor service, will never travel through saudia airline also worst experience at jeddah airport, all the people act like very racist even we belong from a same religion but they don't have any humanity. Very big language barrier no one speak proper English so they don't understand us very poor service. I was traveling with family and with infant they give us very hard time. No one like to answer a question and there attitude is extremely no welcoming. Not recommended specifically jeddah airport and their services and staff. Will never take layover or any flight through jeddah. Thank you

Horrible, by all accounts. Delays, lack of communication, just horrible.

They destroyed my baby’s stroller and the seats was broken

I had the worst experience I’ve ever had with any type of airline,they destroyed my baby’s baby stroller,that cost more than 2000$,the seats in a 13 hour flight was broken,so I definitely not recommend that airline for other people

The flight was delayed which cost me to missed my connection flight.

The planes are very cold. The AC is too much.

On both flights, TAP Air Portugal messed up the seating choices that I paid for. They acknowledged that I had purchased seating, that they were errant in ensuring my choices, but told me nothing could be done about it. When I asked to be refunded, I was directed to "talk to someone from Air Portugal" Mon-Friday, and then I was dismissed. No help, no phone number provided to me. I was very annoyed both times and feel cheated.

Business class seats aren't comfortable. Food was not good.

Great service overall. One of the best international flight experiences Ive had.

Didn't make announcements during boarding, flight attendant seemed annoyed when I asked for water. Too many hours between flights. Confusing check in at the Lisbon airport.

The chicken was so dry it was impossible to eat. No substitute was offered. The port to charge my phone was broken and all I got was a shrug from the crew. The entertainment system was glitchy and subtitles didn’t load. Crew seemed fully uninterested and unfriendly.

Delayed at the beginning and the end and almost missed our connection

The food left a lot to be desired. The crew was great

The crew was great. There was a big guy sitting next to me who was hanging over my side of the armrest the entire time. Maybe some information about "Be considerate of your neighbors, this is tight space, be kind". The breakfast sandwich was not appealing at all.

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?

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.

They canceled my flight and they haven’t reimbursed me yet

On time, kind staff but the aircraft was not clean

I will never flight again with them. No charges plug in the air plane. Just that can tell you how bad the service was.

The flight attendants were very nice, friendly and went above and beyond in making our journey pleasant.

Easy flight, on time, easy check in but long lines.

i cannot remember in the last 10 years, when was the last time i couldn't stretch my legs while sitting. while seated, my knees are almost touching the seat in front of me. the order of Languages of onboard announcements is not the best in all other companies they use their national language FIRST , in air senegal they lut rheir national language last. What a shame

Dirty seats, entertainment unit not working. The crew member assisting in giving boarding passes was rude. She didn’t give us the seats we bought and then tried to give us 4 seats saying they were in the same row which they were not. We had paid for our seats to be assigned!. Food was bad, service was poor. My son had asked the hostess for a sprite which she told she would get but did not

The Airline canceled my flight and don’t want to refund me.

I couldn’t find my boarding pass with the information provided by Underpricer. It took me several hours to find what the issue was. Finally I got the right code to get my boarding pass from American Airlines. Underpricer WhatsApp call center finally got it right. When I got to Casablanca my luggage was left in Miami. Not sure which airline fault it was if Air Maroc or AA. I filled out a report with Air Maroc

Flight was late, economy seats are uncomfortable, and there is no entertainment. Food looked good, although I did not eat as it was Ramadan. Flight crew competent and professional. Ticket was not good value for money. Too expensive.
