The boarding was great. With all the delays I was grateful to get on the plane and headed for home. There was no in flight entertainment. Seats were very uncomfortable! Unfortunately we were seated next to an exit row so there was no recline in our seat. Other than that it was a smooth ride.

The boarding was great. With all the delays I was grateful to get on the plane and headed for home. There was no in flight entertainment. Seats were very uncomfortable! Unfortunately we were seated next to an exit row so there was no recline in our seat. Other than that it was a smooth ride.

My flight was cancelled twice and the third time I tried to rebook it online I cancelled the flight because it looked like I would get a refund to my credit card. Instead I now have a credit. I was also on hold for three hours waiting for a representative and then disconnected. I will never fly delta again.

Flight for canceled. Horrible experience.. had to rent a car to drive myself up here.

We requested wheelchair assistance at ATL. This request was booked in advance of travel, we have requested this service before. We have had issues with accommodations for accessibility in the past, but this was beyond not having a chair on the ramp. We arrived in ATL international gates and had to search for a wheelchair for 40 mins. There were no delta or airport employees available to help. No service phones, nothing. With the help of another passenger I was able to get my elderly mother from the plane to the gate seating bench. She was able to wait there while I searched for a wheel chair.

Flights were terribly delayed. I was at At,anta Airport for over 4 hours waiting for my connection.

My flight consistently said it was on time and the plane didn’t arrive until after 30 minutes after take off and nothing was announced to passengers

Excellent. No issue and it was on time and arrived early, the best!

You cancelled my flight and made me Sleep at the airport.

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

First, the flight was schedule to leave at 12:08. Delayed to 12:38. It is 12:58 and I am sitting at the gate. The staff are not communicating with us (just tell me it’s gonna be five hours if that’s the case, quit hufflepuffing around like you’re trying to board us when the plane isn’t even here and you don’t know where your crew are. I’m still waiting for any communication about the further delay. This is a rebooked flight from a cancelled flight yesterday, when the airline failed to fulfill its fiduciary responsibility to hotel and cover transport for overnight cancelations. Asking about the food on the flight? What food?!? Delta doesn’t serve meals unless you pay for them and you really want me to give delta a high rating for passing out processed snacks (fun size!)? Can we be for real. Delta is cementing itself in history as one of the cheap, stingy, outdated, glory days are over airlines, and it shows. I took this flight knowing delta was going to provide below level service but this is beyond burgers!! I can’t believe a multi billion or dollar company looked straight in my eyes yesterday and I told me this wasn’t their fault and there for the extra cost in hotel and hundreds of dollars in Ubers are MY RESPONSIBILITY. The only thing I am at fault for is believing delta is reputable company worthy of my dollars. I’m not even sure I want to be compensated unless it is cash because I would rather die never traveling again than to put money in their pockets.

Delay, luggage didn’t arrive. Had to go the next day to collect it

The plane. Airbus A330-200. Comfortable for a 7-hour flight. Seats seemed to have more legroom. I was in row 17. Flight was operated by Delta but was better than expected.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

Pretty bad. Food was awful. drinks were scarce, as if drinking an extra drink would ruin the airline. attendants were not very helpful. likely Dutch "directedness" (I cannot be bothered). Crammed flight. Entertainment in very minimal dosage. Almost all old movies and series with 1-3 episodes only. Very limited number of options available. Jesus!! it seems you need to bring your own entertainment these days even of flights that are 13 hrs long!! I would and I will avoid in the future!

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.

Golf Bags never made it on the flight. Very expensive golf bag and. Clubs,shoes, clothing. Will file a claim against Aer Lingus

Horrible. Garbage airline. Due to the strike we got a replacement plane/crew. I didn't get my exit row seat I paid for. Food was horrible. Plane was hot and didn't have AC vents.

Great customer service. Frequent updates from the pilot. Smooth flight. Good entertainment. Meal service.

Long unexplained delay, uncomfortable back row, long waits for trash collection.

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

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.

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

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.

Overall flight experience was good. Unfortunately our process getting to our flight was a hit or miss. Our flight was delayed perhaps for the best as getting from terminal to terminal is very long and security had problems with the machines that delayed us getting to our flight. Heathrow security could care-less that you have a flight you are about to miss!

Access to movies was nice, food not bad, and landing was smooth. Cramming us in like sardines is not fun. A little more space to bend down to get a bag or not touch my neighbors arm because we’re so close would be better for a 9 hour flight. Whomever designed the seating and you, who bought these planes, clearly are NOT interested in customers’ comfort. So stop pretending you do. Also, if you want traveler’s to check their bags so there is space to store carry one, don’t charge so much to check baggage. Seriously?!

Horrible. Crew is not helpful. Lounge is sub standard and overcrowded. Getting to your plane is underwhelming “via a bus”. Worst experience I have had.

I had to wait for 10 hours at the airport and no hotel accommodation was provided. That sucks big time.

They can't seem to deliver a delayed bag in less than a week. Is this the 19th century?

We're waiting an BA flight being operated from London to Raleigh

Could be better in all aspects. Poor communication. Rude staff

The seats are comfortable enough, but the layout in business is wacky. The boarding process is disorganized. The flight attendants are friendly enough, but the food and snacks are sub par.

Crew was great. Food definitely top 10% for airline food. Seat was comfortable and legroom was good, BUT the seats were too close together and I was touching arms with the guy next to me the entire flight. Also, I had an aisle seat, and although my arm was pulled right up to my side, I was bumped by passengers and crew at least 6x. I'm looking into business class next time. One last note: the whole British-AA airlines partnership thing was confusing. In 2024 this should be seamless, and passengers shouldn't need this # for BA and that # for AA. There should be a single unified way of messaging from the airlines and checking things for the passengers.

The flight booked from jfk to Raleigh was pointless. There is no way to make that connection flight although the employees tried their best for us to make it on time. I had to wait 6 hours for another flight
