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

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

The food from Lagos to Amsterdam was was very poor compared to AMS-YYZ

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.

The flight was delayed for 2 hrs. Because they didn’t have a crew to fly. And it is not a first time for klm to do that. Last time they cancelled my filght and rebooked me 3 days later. Not reliable airline

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

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.

The worst airline. Cancelled flight 30 min before boarding and rebooked on flight after 3 days.

The entertainment wasn’t playing in the app or online.

Connecting flights were poor,especially in Naples.our Lufthansa air bus was a joke.way too small for that long of a flight.no room at all.couldn’t even get out of the seats to move around or go to the bathrooms.we thought we were getting an actual air bus,double decker.i will never fly that long in a plane like that again.kind of misleading to call it an air bus.we actually had more room on our buses that we used.

It is a modern tragedy that any airline expects you to travel for 14 hours in such discomfort and that the only way to add comfort is exorbitant prices. I was in pain by the time we landed. Shameful.

Original plane sidelined. Had to wait an hour for replacement.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

They have trouble to keep their flights in schedule. Seems not having enough staff to provide appropriate customer service. Lacking real agents on site to help customers. Have to use QR code/web site/call to be able to talk to real person can help you - and you may have to punch though series of options first, then hold until someone assist you. Similar for baggage claim, no real agent onsite helping if you missing luggage, not like other airline next to UA desk having staff there even after midnight to assist customers.

United is my favorite and I always try to fly United. I feel like this crew didn’t mesh well together.

Our flight was delayed three times. It took us 17 hours to get home.

Plane could have been cleaner. There were many crumbs and crud around the seat mounts.

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

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

Very good need to offer better choice of food for business

They should. Heck planes more often not when they are suppose to be leaving causing delays

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Great hospitality and service! Seats are better cushioned then some

Boarding and crew was great. Flight was cold, need layers. Deplaning was hard. We had to take stairs off the plane and I was separated from my travel companion because we were not seated together and they would not let him wait for me to get off so we were forced onto different shuttles.

Check in and boarding was easy, crew was cheerful. Not much to read or do on the plane and our neighboring passengers were talking loudly so we could not sleep. But overall good. Great coffee.

Flyplay is the only way I travel to Europe. Had a 15 hr layover in Iceland. Normally this would suck, but I regret a car and saw the black sand beaches, several waterfalls and sky lagoon. And finished with lamb at cafe Loki.

did not get the seats we had specially paid for

This is a no frills airline. You cant expect much for the price. Low cost flight, clean, nice staff. That's all I need for the price. If you want more, book with another airline and pay more. For Europe trips, PLAY is the ONLY airline I use

Misleading instructions for check in. Although I did virtual check in and was instructed to head to security, once I was at security, they told me to go back to Play ticket counter and get paper tickets. Also, beware that Play doesn’t participate in TSA PreCheck. I didn’t know that, despite entering PreCheck info when I purchased the tickets. I wasted time in the TSA PreCheck line as well. So we had two setbacks at check in.

It's a budget airline, so forewarned is forearmed. Yes, you pay for everything like carry-on, checked baggage, seat selection, but that's becoming the case with major airlines. Bringing your own snacks and entertainment on board is highly recommended. It's no frills, but the crew, the plane and the flight itself was great. If you want pampering go for a larger airline. If you just want to get from A to B in comfort and safety, Play is a great choice.

It is a low cost airline. Staff are courteous. There is no entertainment. Food is purchased.

Upon boarding, the people at the gate were extremely rude, there were no outlets on a 6 hour international flight, there was no entertainment, all food and drink was purchase only (even snacks), and my seat reclining function was fully broken. The only redeeming quality was the flight attendants were extremely nice. This was by far the worst flight I have ever been on in my entire life

I don’t know how international flights can’t have media screens to keep people entertained for the long flight. Ugh.

Every host and pilot were very professional. My next flight would be upgraded from economy to the next group.

I asked for a window seat and when I got on the plane 24A did not have a window so was very not happy, but good and entertainment was good and the staff was very good, so the only complaint was the seating.

Flights were actually with Aer Lingus outward and American Airlines & Aer Lingus on the return journey. Outward flight with Aer Lingus was good but the return flight with them was not so good as our seats were in a poor condition (15A & 15C) and looked like they needed replacing! The American Airlines flight from Miami to JFK New York was good and the seats were very comfortable and spacious (32D & 32E)

Awful. Flight delayed and we missed our long flight to Rome. It has been a nightmare and we have still not arrived. It was NOT a weather delay, just poor planning by AA

My seat was in a good row. In our section it was the first row. But it was difficult tooperate seat entertainment features > table, screen, even though I often fly.

Boarding was as fast and efficient as possible. The flight crew were amazing and extremely friendly. We enjoyed our flight.

There was nothing to like besides the crew. The comfort of the airplane was poor (seat did not work properly and it was not comfortable). The “entertainment” system did not work! On a flight that last nearly eight hours, (which is advertised as having excellent entertainment options), that is unacceptable! Passengers should have been given free WiFi for the flight. The food served on the flight was below school lunch grade food. (With one exception, the ice cream snack). The chicken entree was tough and nearly impossible to cut and eat. The “pizza” served later in the flight was worse. The chicken pizza had a dry crust and the “toppings” were equally not enjoyable. The amount of chicken and cheese were almost non existent. Overall not a flight we would want to repeat!!

There was a problem in the luggage because there were not porters

2-1/2 hours on tarmac after arrival to DFW, lost connection to London, 3 hours wait for customer assistance, stayed on our own account in DFW, no replacement flight for 5 days, had to cancel the entire travel and return to Monterrey today.

My worst flying experience so far. This flight was delayed a total of 42 hours and diverted to New York before it was finally cancelled. It was delayed 4 and a half hours in London. As we were scanning our boarding passes at the gate they advised that the flight was being diverted to JFK since the delays caused us to missed the open hours for Charlotte international customs and immigration. We were assured multiple times by airport personnel, flight attendants, and the Pilot that we would land at JFK go through customs and immigration and then reboard the plane to fly to Charlotte in the same night. When we landed in New York the pilot advised us as we were retrieving our carry on luggage that we were delayed till 10am the next morning and to see guest services to get a room for the night. During this time I had to purchase a room for a family member in Charlotte which drove over 4 and a half hours to pick us up from Charlotte. This could have been avoided if American Airlines had been up front about the delay. Then after standing in line for over 2 and a half hours at guest services we were taken by taxi to a hotel 30 minutes out of the way. Luckily I looked for other flights that night and found one at 8 am to get on. The initial flight which we were scheduled to fly to charlotte in was delayed 12 more times and was finally cancelled 42 hours after it was supposed to land. I am unaware of what happened to the guest that were supposed to fly on the flight after we were placed on another flight but 42 hours in delays for a direct flight is absolutely ridiculous.
