I have diamond medallion status and usually we are in comfort plus . We were in main this time ( which was fine ) and my husband wanted wine . I have at least 10 vouchers for drinks that are good for this year and next! The attendant would not take the picture of the voucher as proof and never came back to check as She asked me to pull it up on delta Wi-Fi. Instead my husband just used his Amex to buy the wine . Disappointing!!!

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Delta One upgrade it would have been great if my tray extended (it was jammed and wouldn’t pull out), seatbelt had too much slack & my little cabin door didn’t close properly

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

Service in business class was not impressive. I ordered coffee with dinner and then watched other people get 2 refills before I got my 1 cup of coffee, and only after I pressed the attendant button overhead. Furthermore, the seats in the forward cabin need maintenance on this 737-800: the upholstery is detaching from the seat frame, at least on the backs of seats 1C, 1D.

Crew blocked exits to front of ship with galley carts. Also split five person family apart on international flight without fixing.

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

The flight attendants in SLC were rude. I arrived 40 minutes early to gate. Ticket said I needed check in for seat assignments and tried check in and attendants said they weren’t doing it. And proceeded to never call me to give me a ticket so when time to board I received the very last seat. Please relay to employees to do their job better..,

I believe that a four-hour trip should have a meal. Delta had none.

I'm a tall guy and even the seats with more leg room were not as comfortable as I had hoped.

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.

Flight was on time, staff are friendly and helpful onboard.

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.

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

Flight was ok but lack of communication cost me to literally beg to be put on another flight as connecting flight had departed

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.

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.

Great flight. On time boarding. Smooth flight and on time arrival at EWR. The flight crew was marvelous and there was a great selection of movies on the entertainment system. Our bags were at the carousel before we got there. Another excellent flight from United.

Movie selection is good. Crew did not understand mileage program and were no help. Sick later. Food?

It was probably one of the worst flights I’ve been on. The restrooms were never cleaned or stocked. The food was very subpar, and i usually enjoy airline food, so I was disappointed. It was just all around a bad experience. The only saving grace was the flight attendants.

After a delay at the gate, C3, at Ohare on Sunday, I left my Blk ski coat on the bench at the gate, lost! Please review my lob claim, thx.

from SFO-> FRA flight, AVML meal was significantly less compared to regular meal, especially no Desert, no Bread, no sides.

Always wish for more healthy, gluten free options. We have to bring our own.

Flight was good but there are way to many announcements for credit cards etc.

During booking, I kept trying submitting my payment from the Mexican website and it didn't work. After I had the idea to change it to the Canadian website, it worked but I had to be charged the equivalent of 50 CAD more. I received the clear instruction that I would only be able to check-in at the airport and that it was impossible to select a seat 24 hours before departure, that I had to pay 144 CAD to do so, although not only was I able to check-in 24 hours before departure, but I could have selected my seats for free then. All in all, I almost threw $200 out the window due to misleading information. Besides, the app kept crashing, the information to get to the gate on the app was inaccurate, my gate was switched and I was only informed once in the air (luckily I had noticed the departure pannel), I was not addressed in my language beforehand and even if I tried I was immediately answered in English (which meant the crew understood but didn't want to answer accordingly), there was only one snack & beverage service on my medium haul flight and no beverage service on my short haul flight. To be fair, the planes were comfortable, the crew apart from the language issue was helpful, dynamic and engaging, the plane was clean and the directions were clear and direct. United has a lot of potential to be one of my favourite airlines, but the devil is in the details and a lot of them missed the target.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

Staff was rude. Didn’t give water for 2 hours. Worst service

delayed due to weather. Could not communicate with family since the wifi was broken

Flight was delayed 17 hours due to aircraft issues. American did provide hotel, transportation and meals, 3 hours past boarding time, but it took us another hour to get the vouchers.

Did not get any refreshments. Crew was very nice but limited. Small seats

in chicago, you have to go out to drop off your luggage for a connecting flight and come back into a security check. which was horrible with a government shut down. some airports you down off luggage and go to your gate. things were not cleanly marked.

Flight attendants on this flight were very attentive and friendly

I couldn't use their app to select seats or check in because they made a business partnership with UnderPricer to control and sell those options when you purchase your tickets through that agency. And yiu can't get any assistance from UnderPricer. Vueling has made a terrible business decision to partner with them.

American airlines suck they delay the flights all the time made me sleep in an airport because my flight was delayed and I miss my connecting flight

Boarding: Boarding was a bit of a mess. Our tickets indicated "BC" for Business Class, but we and many others were confused as that was not indicated anywhere in the airport, so we didn't know when we're supposed to board. The airplane: The airplane was nice. However, we sat near the back of the business class cabin and the flight attendants and passengers from other cabins would constantly move the curtain (which was very loud), preventing me from fallling asleep on my 8 hour flight. The flight crew: Amazing, generally. However, they nearly forgot to serve breakfast to me. The flight food: I was able to select my meal for dinner, which was really good. Breakfast was a bit of a mess, however. The crew forgot to serve me breakfast until the last minute. Very little was available by the time they remembered. The entertainment: Paltry, underwhelming, and dated. Not one new movie was available. Bottom line: For the money, you might want to consider other options for your international business class flights.

We arrived 4 hours early and still almost missed the flight because they weren’t able to access one of the boarding tickets. They then sent hour bags late and we were all of our without clothing and eventually had to take an expensive cab back and forth to the airport as they wouldn’t deliver the bag which arrived late at night that day and we would have to wait until noon the began day (messing up a second day of plans). Also, all the food has dairy or pork. No vegan or even vegetarian option in the flight—even for purchase.

The flight delay in Dallas created a domino effect that impacted all of the connecting flights. It also increased the number of connections. I missed my flight from Casablanca to Marrakech because of the tight turnaround when landing in Casablanca. . CMN airport was understaffed. Only one person could help while other employees were just watching him. It was an extremely frustrating situation. People were crying and slamming their palms on the counter when speaking to the customer service provider, Allabough (man’s name?). Allabough couldn’t change my flight in the system. simultaneously, I was on the call with America. Airlines customer service rep named Solomon that said he couldn’t change it either. So, I took a ONYA voyages train to from Casablanca to Marrakech to get there on Friday June 26. This was unpredictable trip.

Bad weather Excelent pilot Spoke British 😆on time seats small ad expected in a discount airline

It wasn’t great because the third-party from Kayak there was just no information about how to check in with Vueling. And the purchase of the ticket from under pricer just made everything really difficult. I’m unlikely to use Kayak again for these reasons.

It was fine, older plane with limited entertainment, otherwise fine.

the seats were bad and uncomfortable and the food was not tasty.

the seats were so cramped you could barely move. it was difficult to eat when passengers would recline their seats. the seats were so flimsy and unstable that whenever someone got in and out of their seat, it bounced like a spring back in your face. the movies were nice. the food was terrible. even though the conditions were terrible, they tried to pressure passengers to relocate their seats to accommodate adults who were related and wanted to sit next to each other, even after the passengers expressed that they did not want to move for that purpose. on the connecting flight, the “service” consisted of items for purchase. even though the flight was only 45 minutes, once again passengers (including me) were pressured to relocate for people to sit next to each other. they couldn’t be apart for 45 minutes? this was much less compelling than being apart for an 8 hour flight.

Everything went smoothly, and we even arrived 40min earlier than scheduled, on an Orland-Madrid route.

It was budget airline Veuling, even though we booked Iberia.

The staff was very nice and helpful. Some of the best crew I have met.

Bad experience. The seat room are very tight. The food is not good and the breakfast has no hot drink.
