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

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.

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.

This flight was ridiculous. I had to have a connecting flight from New York to orlando Florida??? The flight left late and because it was a short flight there was no first class amenities. I had one alcohol drink. The flight crew was fine, but it sure did not feel like first class. Delta to me dropped the ball by giving me a connecting flight. By the time we got to Raleigh we would have missed the next flight. Lucky for me the flight never came so now I was stuck waiting for a later flight that came in late also.

Had to run to make it only to have the flight delayed to wait for all the late connectors Second drink service skipped up

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Had assistance at airport getting from arrivals gate to departure gate; I couldn't have managed without that extra help. Thank you Delta.

Boarding super slow with people allowed to linger in aisles

We checked one bag. That was fast and the agent was fast and super nice. At the gate, boarding was fast and efficient. Flight was uneventful which was great because it was early in the morning and most folks were sleeping. Landing was great. Delta does a really good job of making the flying experience better all around considering you are sitting in such a small space on a plane for several hours. Flight from ALT to Panama City was short and uneventful as well. No entertainment but no need since it was such a short flight.

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.

they made me check my carryon. There was space in the overhead bins.

No in flight entertainment, gate employees were very quick and impatient, plane was uncomfortable

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

Got automatically assigned middle seats unless you fork out extra money for a seat assignment, not impressed.

Poor seating comfort, seat cushion too thin, very uncomfortable. My luggage didi not make the flight due to equipment change. At least. United had it delivered the next day. I was without my toilet items for one day.

First, the bathroom was horrible. 2 bathroom stalls at a gate and no soap to wash our hands. We were sitting at the gate for an hour before they decided to check our particulars. The line was long. Boarding was chaotic. Once we boarded, we were put on the bus in the rainy and forced to stand like sandwiches in the bus. All this occurred on Christmas Day.

There was no in seat entertainment, you had to spend $10 on their wifi which worked poorly at best. You were allowed ONE one oz snack for a 3.5 hour flight. Seats were made for midgets. I am a regular size adult male and I had to wedge myself in. Not a fan.

Seat didn't recline all the way back. Very uncomfortable flight for 8 hours. The turbulence eliminated snack and food stops

Crew and snacks were great. It’s nice to have free wifi for entertainment, but there wasn’t anywhere to place my phone (ie Alaska Airlines). Also the gate was right next to another that was boarding at the same time, so it was difficult to tell where the line for our flight was. Also, they didn’t have a speaker system and had to yell for different groups. Had I not gotten a text that the flight was boarding, we might have missed the flight.

My fi t er t esed to Denver was cancelled and need to schechedule

Not being able to purchase my check in baggage online was a negative.

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

Overall okay. Ipgrades ate worthless anymore. Wish I’d not been so loyal To them for so many years. Platinum many years. Gold for life. Usually 20th-30th on upgrade list.

After my luggage was grabbed by another passenger, by accident, I chose to speak with the American Airlines staff within the airport. Not only was the customer support staff uninformed but also very argumentative, making this situation harder to deal with. I was only able to finally retrieve my luggage thanks to the passenger who took it contacting me due to the tags on the luggage. All of this was happening during another 2 hour delay and 3 gate changes. Horrible airline with disgusting, on the ground, customer support staff.

We could have left on time. We were an hour late.

Boarding was efficient. On board drink was slow. Temperature was a bit warm in the beginning.

Il y a eu 2 heures de retard, ce qui n' a pas permis de prendre la correspondance prévue. L'absence d'information claire et précise a entraîné des tergiversations avec les autres compagnies et a failli entraîner un retard encore plus conséquent. Seul un renseignement de l'aéroport de Francfort a permis de trouver une solution. Au final, c'est avec plus de 4 heures de retard ( 9h50 heure arrivée initiale, 13h50 arrivée finale) que notre fils et son ami sont arrivés. Cette différence s'expliquant uniquement par la responsabilité de la compagnie aérienne. Une indemnisation est-elle envisagée. Cordialement Mme Giraudo

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

Food was very bad, eg noodle dish that could have hardly cost more than $1 plus a dry piece of bread a sad salad and a fig bar. Entertainment was also disappointing, mediocre movies and Tv shows and barely any classical music.

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

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.

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.

Both flights were delayed due to maintenance issues. Because they where late boarding all four of our bags where left behind on our last connecting flight.
