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.

I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

Delta is one of the best airlines I have flown

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 was pleasantly surprised - it has been awhile since I traveled with them - other than being delayed leaving Malaga everything ran very smoothly- yes I would travel with aer Lingus again and yes I would recommended

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.

Flight staff very friendly and helpful where possible. Late flight and travelling with young child, cabin lights remained on for the duration of the flight which was a little disappointing considering the time of the flight. Overall very happy to travel with Aer Lingus.

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.

Delayed due to weather... fine. But then the board us. Rows 15 and back had to go down the stairs and back up the back stair entrance to the plane. No assistance offered. Then they inform us that we are delayed for paperwork for an hour. So why did we board? Then, about 45min later they inform us that it'll be another 60-90mins. Really? No wifi, no seat entertainment, no drink or snacks offered. And we were not allowed to deboard.

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!

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

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.

Typical experience for budget airline. Boarding from KEF required bus transit from the gate to plane, so if you had "priority boarding" it was useless as it was simply a free-for-all when getting off the bus. But still no issues with getting our luggage into overhead bin so not really a problem.

Was very apprehensive about flying Play, but the flight was fine. Nothing special, nothing horrible. Fair price to get from New York to Iceland.

I wasn’t able to check in online the day before or the day of because their web configuration or business model idk. I arrived an hour early and check was closed and there was no one around to speak to and eventually was told there was no possible way to get a digital ticket despite I had no luggage to check and would have easily made it through security to boarding and had to pay for a new ticket for $330 ontop of the $169 I spend for the ticket and then I missed my rental car for $305 because I only arrived at midnight instead of noon that I was originally intended. All booked through kayak. I hope there is some kind of insurance from kayak because this was totally preventable had I not been blocked by play air from getting my check in and plane ticket.
