The required privilege for business class while boarding is not given. Food is average. The seats in business class are bad, worn out and dirty

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.

The service was great. However the lounge only gets passing grade

Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

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.

Quick and efficient as always. Air France managed to loose and damage my luggage that never made it onto my KLM flight.

The flight was again delayed for more then 2 hours with some lousy explanation regarding the reason of the delay. Although the flight was delayed for more than 2 hours, no refreshments were offered (according to EU regulations). Last 4 flights on KLM - always at least 2 hrs late. So be prepared that you cannot plan anything with KLM.

I travel frequently. The flight was late again... KLM should really try and be on time

The seats were really comfortable. Flight crew were friendly with passengers. Overall was a great flight.

Great crew, flight on time, luggage pick up a breeze

Unfortunately I was stuck next to someone who should have purchased 2 seats instead of taking up their space and mine. I couldn’t move the entire 3+ hour flight. Very uncomfortable flight.

Older plane and it came with Fleas and flea bites!

More extra space was awesome. Even though I was on the first groups to board, bin compartments were already occupied by passengers seated on other seat numbers. That is unacceptable.

Crew went over and above to be helpful. Plane had mechanical problems that caused us to depart late.

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

The flight was excellent, I recommend people to fly with Delta

They charge me for the luggage which is was included on the ticket

When we enter the airplane there were many water drops falling from the ceiling all the way long to the seat , and when it departs were even more over us getting the hair wet , and later on was too hot , the A/C not work well.

I bought this ticket for my daughter. She had to pay for her carry on bag to be checked. My understanding is that transatlantic flights included carry on and personal item The nickeling and diming fo legacy carriers has stooped to an all time low. So sad.

It’s always a great time flying with united airlines.

Awful. There was a minor problem with a fridge and they had us 2 hours in the runway before take off. The paper work alone took them half hour. There was no attemp to make up time up while in teansit and when we arrived, they had us another half hour in the plane because of traffic. I, and a bunch of people, lost their onnection flights for 5 to 10 minutes. Not even the attemp to wait given thar all delays, but the taxing, were United's fault. Then another 45 mins to get an agent and no flight alternatives for 2 days. Im am very disapointed with this "premium carrier".

No food service almost missed because of first flight delays

Checked my bag despite paid the seat upgrade and there was plenty of space available in the overhead bin.

Good plane, crew, and flight. Boarding was a bit chaotic. Bathrooms were unacceptable. United DESPERATELY needs a new terminal at IAD.

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

IT WAS A LONG TIME SINCE THE LAST TIME I TRAVELED. I THOUGHT I WAS TO BE LOST BUT EVERYONE WAS PRETTY NICE WITH ME AND MADE MY EXPERIENCE NICE. THANKS

Your app is impossible to use. I couldn't load it. Then i couldn't open it. When i finally got both those things done -with much help -then i couldn't open the app to install a credit card. The upshot was 4 flights without access to food or drink. When i first tried to download united app some company called starlier opened instead and i would up signing up for some 49 dollar a month music service which i still have not been able to cancel.

There was a delay that was unexpected. The seats were uncomfortable for the length of the flight.

AA was a very good experience. The employees are wonderful

There was no inflight service. Once we landed we were delayed to find a gate for an hour and a half which was 1/2 the total time in the air.

The economy seats are very cramped and the food was bizarre. However, I did like the greek yogurt option for breakfast.

We had a very pleasant flight with very comfortable seats and nice staff.

horrible our connectig flight was late and we had to rush thru DFW to the next gate with 15 minutes time. Get to gate and its changed. no one knows whats going on . finally get a new gate and the plane has been sent back to the hanger . Boarded 4 hours after our original flight time and then sat at the gate for over an hour as the captian said the cargo doors were open and no one was in the airprot or on the ground to find out what was happening. this caused us to miss the first day of the tour as we missed our transfer and hotel meetup no apologies or accomodations offered to assist

Seats in coach aren't padded enough for a 6 hour flight

My trip was delayed for more than 3 hours without any explanation. Also I have a business meeting that I lost.

the handling of my luggage. It was Lost or stolen At my destination.

If we travel with carry on expected to being able to carry the luggage. Could be good if take in consideration the date of reservation to do that

Uncomfortable seats at row 40 A and 40 C, they didn’t recline. Also, my prior seat selection was not honored.

I will NEVER fly with this clown show airline again. Idiots. All of them. Unprepared. Unfriendly. Miserable employees. NEVER. EVER. AGAIN

Easy experience even with the outbound flight being delayed. The seating and space was comfortable and the crew seemed very nice and helpful.

Flight was smooth, amenities (entertainment options and power outlets) were good, sears decent)

Disaster This is why I stick to delta You get what you pay for

Well, its a hit or miss when boarding most of the time your employees just let everyone enter immediately In one bum rush. Then out of know where tell the passengers only let A can enter then b then c etc. So make a decision and stick to it. Do it by alphabet and have famn strick compliance. Let the public know. That makes easier on passengers.

It was a pretty smooth flight, I tend to get mini anxiety attacks during flights, however, this time was pretty smooth and I was able to relax. The only thing, I was having issues to connect to the Flyfi internet. I was not able to connect at all, I turned off my phone a couple times and didnt work.

we were delayed because of some safety check that wasn't done or available

The flights are back on time and everything else runs perfectly.

They announced at the last minute that international travelers had to checkin at counter. This created a long line and unnecessary stress.

I cannot say this enough, I NEVER BOARDED OR HAVE HAD ANY TRAVEL IN THE PAST YEAR. However your app says ive been traveling a lot lately. GET REAL HUMANS TO GIVE CUSTOMER SUPPORT.
