The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

After a 5 hour delay waiting at the gate (3 delays adding up) with no clear reason provided, we finally boarded flew 3/4 of the way to Toronto then were turned back to New York. As we neared New York, the pilot declared that it was his fault, something to do with timing and him not being allowed into the country???? How could the airline let his happen? They had hours to prepare and make sure they had a crew available for the flight! We ended up in Toronto a day late with no sleep.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

Terrible and im avoiding them in the future. My initial flight was delayed causing me to rebook my flight and when speaking with the representative to rebook I explained this is the second time my flights were delayed and they did nothing to help me. I wasn't booked to comfort plus or given a voucher or anything. I was almost late for my meeting that I needed to attend on Monday because of the games delta played delaying my flights even more and putting me in the very back of the plane next to an extremely intoxicated passenger

Friendly flight attendants, smooth 8-9 hours flight. Economy seats are small and uncomfortable as usual.

Flights on time. .Ride was as comfortable as can be expected in steerage. Luggage arrived at destination. Attendants were fairly friendly.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

The WiFi didn't seem as fast as it normally is

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

You should not have to pay for WiFi in business class

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

Great boarding, great short flight but no entertainment whatsoever. It was supposed to have wifi but that did not work.

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 flight with KLM, friendly staff. Food was good, had much worse on other airlines. Selection of drinks also good enough for us. Entertainment was also good. The economy seats are ok and that’s it. For a 12 hour flight I think a little more comfort in the economy seats in pitch and softness would be highly appreciated by the customers and can makte the difference.

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

1. Nowhere to sit at the gate D4 2. No control of lining up in different zones 3. People pushing in during the line up of zones. 4. Certainly not in a dignified manner.

Everything went smoothly. I appreciate the selection of free movies.

I like the friendliness of the crew members. I think the snack could’ve been better instead of a small package of pretzel. I like that they offer me something to drink.

The TSA agents in Phoenix were incredibly rude and confiscated belongings that we wanted to check. The flight got changed without our knowledge to a worse situation. The whole thing was terrible

Air Canada was great! From the airport at Montreal to boarding to the food on board the plane. The crew was great too! There was a slight issue with some other peoples’ tickets that I overheard about but the crew handled with care immediately to ensure everyone was comfortable and we could takeoff! Great experience with Air Canada

My experience with Air Canada was good. Great customer service… only a few delays and issues with the tunnel to exit the plain. I did not appreciate that we arrived at terminal D and had to go to terminal E to get the bags/ luggage.

PDX staff was great and we arrived on time in YVR.

They announced before boarding that the flight was full and there would be limited space in the overhead bins and you could check in for free. We did and after we boarded the plane found it was not full and there was plenty of space in the overhead bins. I’m not sure why they made this announcement.

Front desk attendant wouldn’t check me in even though there was not a single person in line. Made me use the kiosk. Kiosk had an error (of course) no baggage can be checked at this kiosk please see attendant. Then I had to wait in line for the same front desk attendant waiting for 5 people who ended up coming in front of me while I tried to use a broken and useless kiosk. Finally after checked in, wait 30 min to board all the way to zone 6 and they would deny me even after all the zone 1-5 people already went. Just literally making us wait to board so they stand there doing nothing for 5 minutes. Just ridiculous and awful customer service. Fly with literally anyone else

They are a great airline, and i enjoying flying with them. However my experience with booking through Kayak was a horrible experience. With all the restrictions and glitches of website. My entire bookings by kayak was wrong. And there was no possible way of fixing anything with them, because they hand over responsibility to the airline after purchase is made. Will not be booking through Kayak again and will inform my family and friends not to as well.

Was late but that airport/storm fault. Flight was full but comfortable. Food quite nice. Unfortunate that I had a rather miserable attendant, others were much friendlier

Experience was good. Could have been better if we didn’t have to board an hour before the flight to ghana and miss relaxing time in the lounge. That process was very stressful

Boarding crew is unfriendly as i was asked to handover carryon luggage too upto final destination Bangalore I was not prepared for that and i had to travel without my diabetic and hypertension medicines

I was charged fees for check in bags at the airport by British Airways. It was supposed to be no charge but Kayak messed up my booking apparently and I had to pay for check in bags. I paid $175.

They took my carry on and checked it in. Staff in general at Heathrow are not friendly or helpful

The crew were professional and friendly. It was the most uncomfortable international flight I've ever flown. Crammed in passengers. No overhead space to put my bag. No leg room and unable to recline seat due to seats too close together so it upset passenger behind me! Upgrade price to get 2 inches of more space unreasonable.

Boarding in Dallas was hell with extremely rude gate agents , especially a lady named Rajathi who was the epitome of rudeness with no compassion at all . She was horrible and I wonder why airlines have people like her on their roster who exude arrogance and haughtiness . Will probably not fly British Airwsys because of people like her .

Less than average, low level of shared required information needed during the transfer from airport to another, also the used team during boarding In Indianapolis station is Not Professional

Food was average. Better headphones seats were average at best.

Nice flight. Legroom was good. Food was good. Staff was friendly and helpful. Plane was modern and clean. Seats and headrests were comfortable. Entertainment system was good and modern, with a bright LCD screen and many appealing choices.
