The food is terrible. The same pasta or chicken with bad taste and presentation

It was probably one of the worst flights I’ve been on. The restrooms were never cleaned or stocked. The food was very subpar, and i usually enjoy airline food, so I was disappointed. It was just all around a bad experience. The only saving grace was the flight attendants.

The only downside was my cell phone charger wouldn’t work in the charging port but everyone else’s would work in them all. My cell phone cable works fine in my hotel room in Frankfurt.

Very thoughtful flight attendant offered me water immediately since I had run to make my connection.

Great crew, excellent landing, good food. Over all great experience. Thank you!

One bag is incorrect and not acceptable for an international flight. The food was not just good. I won't fly with them again.

Not pleasant trip cross country when the entertainment and WiFi system not working. No entertainment for entirety of route. Staff was rather nonchalant in that they dismissed the problem due to age of plane. It would have been nice to know this up front so I could have come prepared to read or download movies before boarding Coincidentally or not, there was a similar issue with the entertainment system on my previous flight I took on my fist leg of the trip. There are no seat TVs, so you must rely on the app when it works. United can do better. Also, what use it it to pay for boarding group 2 when half of the passengers are in the same line as you?

Crew was dismissive. Snacks and refills not offered. Poor business class experience. Bed not comfortable compared to Emirates or BA.

Flight was delayed for 5 hours because crew didn’t have enough time to rest - this seems like it could have been avoided with better scheduling. Food was not good.

IAD with the archaic people movers is just a place to be avoided.

Seats are small, but comfortable and more space around you, so for a normal person the seats are perfect. If you are a big and fat individual, I would not think the seats are comfortable. All else was good and normal. Lots of movies to watch.

Customer service was excellent! The app was terrible, tried several times to check in without success! But the young lady that checked us in was absolutely terrific and helpful.

The same as I stated prior. We incurred extra costs that should be reimbursed, given we were not communicated with about schedule changes.

Experience was great overall. However, the connection time between my flights (1hr 15 mins) was too short. We had to get through security check and US immigration in that time, and I made it to the gate just as they were announcing it was about to close. Flights with such a short connection time should maybe not be offered for purchase, or an advance alert would be helpful. Other than that the in-flight experience was excellent, especially the food. Many thanks!

The seats needs to be comfortables, at least please add more padding to the seats.

Incredible service. Incredible entertainment. I felt like they just kept serving us something new avery hour. My wife and I both had a joyous flight.

They out me in the baby row so I was surrounded by toddlers, they also did not send my luggage and was not able to book my connecting flight

I was so grateful for the kindness of the crew. They made a long trip very pleasant. Food was delicious. Many movie options

My flight from Dublin was delayed two hours which ment that I missed my connecting flight to Phoenix. American Airlines provided a hotel room and rebooked my flight for 7:30 AM the next day. I didn't get to the room until 11 pm and I had to be at the airport the next day by 5 AM. The airlines did their best but the schedule was challenging for an 81 year old.

Dinner was fabulous. Would have enjoyed a wine with it. None offered... for sale??? Breakfast was disappointing but adequate amount of food.

Again, we paid $ 328.00 for specific seats are were assigned those seats.

Never again. Terrible hospitality and human decency for an international flight. No food, no snacks, no beverages, blankets, pillows, limited entertainment. Tiny seats without any cushion and some do not even recline. I was shocked that they did not charge for seat belts. Never in my life have I witness asking for "spare change" for charity before landing on both legs of the flight. Icelandair can contribute on their own to said, so called, children's charity with the money saved from providing 3 centimeters of tea and water to hungry and dehydrated passengers.

Having been prepared for paying for everything on board other than water, coffee and tea the service was OK. Food and drink is expensive but the food was OK if limited in scope. Plane was clean and obviously well serviced. After complaining about having to walk in wind and rain to a get a bus to the airport the same thing happened at Portland. I’m sure you could get a terminal gate flight, complimentary food and drink for not much more money without traipsing through rain and slush in Reykjavik. Not bad but not great.

If there was a disclaimer regarding food service or lack thereof, l missed it. If l had known l would have prepared better. Same with transferring at Reykjavik. No information about disembarking via stairs into rain, slush and puddles deep enough to swallow a foot. After being treated to haute cuisine restaurants and warm inviting environment during the flight, the airport is, let’s be kind, disappointing. Plane was comfortable, Airbus, staff were welcoming enough. I would likely try the route again. Maybe have a night and day in Iceland. Maybe not.

They had a 4 hour delay and left my luggage in Iceland and it didn’t arrive in Portland until 11/1

The boarding process seem to take longer than necessary, resulting in a 20+ minute delay

Handling our luggage was the biggest issue - they lost it and we got it almost 3 days later. Really threw off the beginning of our trip and we really had to change our itinerary accordingly.

No meals included on this long international flight. Most airlines will offer you a meal when flying internationally. Not Icelandair. Your included choices are water and coffee. Poor customer service. The airport was also very confusing.

I flew Icelandair with my partner from Prague to the US. Overall flight time was around 12 hours, with a connecting flight in Iceland. I have flown internationally for years and with multiple airlines. Every airline serves you a meal when traveling internationally. Icelandair not only did not offer an inclusive meal, but they did not even offer a snack. The only things they served over our long flight was water and coffee. Ridiculous! Never again will I fly with Icelandair.

Best smelling onboard bathrooms ever. Even after use the whole flight. Biggest overhead bins. Most legroom in economy class. Great Icelandiic music. Really nice staff. Icelandair is awesome! (Don’t fly Air Canada! During the strike they lied about no flights available (I booked this flight myself) and hid the process to get money back on their website by obscuring menu titles, then made it difficult and time consuming to fill out. I’m Canadian. Don’t trust Air Canada!

Excellent experience in every way, from ground crew helpfulness, boarding experience, inflight service all the way to modern equipment. My new favorite airline. I wish I could fly with them more often.

For a no frills flight this was surprising comfortable. The crew were helpful and nice. The flight was smooth and there were no delays or issues which I haven't had on a flight in a long time. I would definitely fly with them again.

The flight was canceled by play less than 24 hours prior to the trip, and I was unable to re-book. Have not received a refund for the trip despite filling out the appropriate form.

Was was cancelled less than 24 hours prior to my scheduled departure by PLAY. Despite my attempts to rebook my travel, I encountered significant cost increases that rendered this option unfeasible. In accordance with EC Regulation 261/2004, airlines are required to issue a full refund for cancelled flights within seven days of the scheduled departure if a refund is requested instead of rebooking on another flight. It has been three weeks without a refund or an answer

Have not recieved full refund for my flight, which was cancelled less than 24 hours prior to my scheduled departure by PLAY. Despite my attempts to rebook my travel, I encountered significant cost increases that rendered this option unfeasible. In accordance with EC Regulation 261/2004, airlines are required to issue a full refund for cancelled flights within seven days of the scheduled departure if a refund is requested instead of rebooking on another flight. This request was completed three weeks ago an answer or refund.

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
