Attendants zipped through cabin so fast hardly anyone got the water they told us we could have in the short flight. Nothing else was offered.

Attendants zipped through cabin so fast hardly anyone got the water they told us we could have in the short flight. Nothing else was offered.

Sucks ! All three flights I was on this trip were delayed.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

The flight attendants were unhelpful. It was a packed flight, and usually a flight attendant would help find a spot in the bin for your carry on or shift things around. Neither made any effort to do so. Also, I had to then check my bag. I was told it would be on the carousel in YYZ, but it came up on the jetway. So lucky I saw others standing around for their bags. I would have walked straight past this and on to the carousel. They could have at least told me that they had given me wrong information. Very unsatisfactory.

The crew was outstanding. And the food was surprisingly good. The chicken and the pasta dish were both delicious and I was supposed with a pizza twist near Landing. We hit a lot of turbulence and the crew was calm and kind. Loved the TV in screen. Tons of new releases.

ANA was great. United was horrible. They bumped us from economy plus to economy and were supposed to contact us for a refund but no luck. We booked the seats 9 months in advance.

Smoothly flight, pleasant flight attendants. I wish there were better food choices.

Comfortable as it can be for a basic economy seat. The TV screen on my 15 hour international flight went out after 1 hour or so and it never worked again. The food is very high in processed carbs and sugary items.

A three (3) hour flight should have meal service in First Class, not just potato chips!

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

Again, lines for boarding are a problem in iceland. The flight itself was fine and very smooth. No complaints. We would definitely fly icelandair again.

take snacks and food. purchase options in flight are not great

Had a screaming child next to us. Not the airline’s fault but still annoying.

Never took flight. See previous comment on trip from Boston to Reykjavik. Used a different airline that i had to find and book.

The flight was on time and the crew was nice. I did not like the fact that my husband and I were seated in different rows. I feel pressured by airlines to pay more to choose our seats. We will sit anywhere, but we shouldn't have to pay to sit together. I also think they should serve at least a snack that's free.

One of the worst airlines I ever flew. Boarding is a disaster, they are always late, the planes are overly crowded. Everyone on my flight lost their connection because they were 2h late. Reykjavik is also not the best airport out there.

My only area of issue was the flight was rather warm and the knobs for cool air didn't allow much cool air to come through. Everything else was great.

Been travelling for 2mo. And when you meet flight Attendants that love their jobs you can just tell. And makes flying with them worth another flight in the future!!

Everything was great! My only critique is 25 euro for wifi is wild, but I get it

Good, but I feel there should be a separate boarding line for seniors

Really lovely trip and flight. The flight staff were so accommodating and warm throughout!

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Was not aware that Aer Lingus was like the cut-rate services in the states, with no food or beverage (other then 3.50 Euro coffee) and no screens for entertainment. Was a great flight, but not much in the way of services.

during a very rough flight, I was forced to sit in a last row seat, fell asleep, and was forced to return to my assigned seat after the turbulence. The stewardess then used that seat to sleep.

I didn’t realize Aer Lingus was a “nickel and dime” kind of airline where you had to separately buy all the amenities you wanted. The push to purchase duty-free beauty products was off-putting. And our row had the least amount of leg room I’ve ever dealt with on a flight.

We couldn't talk to aer lingus we had issues with the flight change and aer lingus made us talk to kayak

Very pleasant staff, there was some turbulence but the captain was very apologetic and gave notice where possible.

Flight was great. Had to wait almost 100 minutes for luggage (some problem in the delivery). This may not be an Aer Lingus problem, but an SFO problem.

Loved it! Best airline to fly with. Nice crew, good planes, good food!

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

It would have been better to have USB charging ports available on the longer haul Flight that one of 2 hours

Was very good Staff was great. No tv monitors tho. So long flights make it longer

The worst. No free beverages. No entertainment on an overseas flight. Not enough space. Never again.

Play is affordable! Only way we fly from the states to Europe. Left late but arrived on time

have screens on backs of chairs...offer free snacks and water

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

The only thing that the airport can improve which will help Lufthansa from delay flights is to warn the passengers that are flying to the USA to be earlier to the gate due to the documents check that in our case delayed the flight

This was the best carrier, comfort, service, good food, on time experience on a long haul flight. New, clean, quiet, smooth aircraft!!!

Liked - efficiency of boarding with 2 jetways. Checkin was with kiosks with helpful and plentiful workers to help with the process. Munich airport security was very automated, efficient and effective. Free wine and beer! Cons - food was only okay in economy class. Plane bathrooms could have been cleaner.

Disappointing. Too many let-downs, in delays and communication, by both Lufthansa and Discover to put in an email. I am resigned to the fact that this is what I should expect from all airlines. Unfortunately.

Crew were professionals. However, the plane seats are too small -essentially there is no space to move around which for so many hours is almost inhuman but certainly unacceptable. Same with the bad quality of food and the fact that you need to purchase Wi-Fi

Sorry, I’m not a fan of United. The seats are just too cramped and uncomfortable if you are traveling very far.

I think it was a United A380 plane. The trip from Munich to Denver was about 12 hours and the preferred economy seat I paid $75 for was very cramped. The crew was nice but I was so uncomfortable and getting up to walk around didn’t really help. My legs were swollen for 4 days afterward. I would think on such a long trip the seats would have more room. I would have gone 1st class but it was 3-4 times more expensive. I won’t fly anywhere far away again. My last experience with Lufthansa was great to Italy and back, but this time I could swear everything was United and not good.

Boarding was total chaos. They didn’t know what they were doing and taking bus to the airplane is like going back in time. The food is bad, portions are very small and we don’t get simple paper napkins! Is it really that bad?

Great crew dealing with the most unprepared family with a million kids and zero sense.

We were disappointed not to be able to buy out preferred seat from date of my original booking, which was about 40 days before the trip. When we arrived in Hannover on the Oct 10 I tried every day and the weed site said I have to wait until ck in, did that and still was not able to. Get to the airport and out seats were separate from each other. The crew was able to get seats together, was not the most comfortable. Don’t understand why this happened.
