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!

It was a good experience except when boarding a female flight attendant did not go out of her way to assist my teenage daughters in finding space for their carry-ons after their compartments were full.

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Big plane, long flight, absolutely no leg room and basically non existent air! I am 5”4’ and always travel Main Cabin, I was miserable on this plane and could barely move when we arrived in Cabo due to the cramped leg area!

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

The pilots were good. Disappointing when planes don't have electrical ports

I liked the piloting of the aircraft. Very disappointed about lack of electrical ports. Also, although a short flight. there was enough time to hand out snacks to comfort + seats as was done for first class.

Seats are fair enough for medium tall people. Good food all the trip. Fight attendances are warm

I thought KLM was the best airline but the Lima - Amsterdam was 1 hours late, the Brussels - Amsterdam was 2.30 hours late and the Amsterdam - Lima was 30 minutes late

Overall a good experience. We were disappointed when we had to check our carry on due to the plane being full. KLM hadn’t notified us and we had valuable items in the carry on but they still made us check it. Some of the food was great and some was mediocre. Crew is really kind and funny.

It was nice to be on a legacy airline, people try at least.

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

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

The food quality is poor. The staff are very friendly and accommodating. The entertainment program was limited. I experienced a delay of 30 minutes due to two issues. Passenger luggage had to be removed and there was a technical issue with the stairs not detaching from the aircraft. The pilot managed to compensate and we arrived only 15 minutes later. The luggage at Dubai airport was very slow. I waited over an hour.

The boarding was one of the worst I’ve ever experienced. The fault lays on Ohare Airport and not so much the airline. The waiting area by the gate was the size to accommodate a regional flight for 20-30 people and right next to a busy walkway. When you cramped nearly 300 passengers into that space is was unbearable.

The seats are too cramped in that plane. If you’re above 1,80m consider alternatives or first class I guess… There were no emergency exits to seat somewhere with more legroom

At the transit could be less time not like 12 hour 6 hours the mix should be 4 hour, thanks

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

Short flight so not much to rate. Surprised I had to pay for a soda.

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Very good need to offer better choice of food for business

Great travel. Wonderful experience. Hope to do it again in the near future. God willing

Aer Lingus doesn't have plug ins for devices at each seat. They also did not give me a dairy free meal as requested and confirmed by staff. It was as if I had not requested anything. Otherwise, they were great!

The transatlantic flight was wonderful. The regional reminded me of jet blue. Crazy and packed. Not enough overhead space and tough on elderly.

All OK. Food, best bring your own. Even a BigMac will be better.
