Flights from Dulles Intl to Reykjavik: the best tips from KAYAK users' own experiences

Insights shared by verified travelers who flew the route from Dulles Intl to Reykjavik 
Lei-SeaFlew with IcelandairAug 2024
KEF is not like American airport, not a lot of seating and gate is announced when boarding starts so be prepared to move quickly. Food is good in airport and lots of seating around the food areas.
MilyFlew with PLAYMar 2024
Come at least two hours earlier than your boarding time. These “discount” Icelandic airlines are barebones with instructions. Eat outside the airport beforehand. The food sold on Play is very overpriced.
Verified travelerFlew with IcelandairMar 2024
I wish I would have known that you don’t even get a snack for an overseas flight.

Excellent from start to finish. All staff members were amazing!

Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.

Cancelled flight with no specific instructions to get a boarding pass for another flight. The whole flight of people were in line for an hour because there was only 1 person to help at the desk. This was unusual for JetBlue.

It was too hot in the cabin. The AC did not help.

Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking

No music app working: no economy meal on five hour flight; hour on tarmac at the end waiting for a gate. Flight itself was smooth and easy.

It took 1-1/2 hours to get our luggage after we landed. That to me is unacceptable

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

Overall was excellent. Will definitely us JetBlue in the future.

For an economy lite experience, it's by far the best I've had. New planes, clean, great destinations. Very happy to have discovered Iceland Air.

Smooth efficient airline. Think they should have their own bag drop as the queue took 30mins to bmscan and drop

No food was served for 7.5 hrs flight. When our flight changed to other airlines due to wether issue, our seats booked with no checked in luggage when I already payed for. We end up to pay 90 euro per suitcase.

The flights were in time and the bags arrived. well done

Only serving 2 small coffee in 7.5 hrs flight with very limited choice to order food.

Booked with Kayak… Economy Class it said. I had filtered for 1 checked bag. Get to boarding and it says I have Economy Light w/ no checked bags. $136 each way for baggage now. Do not use smartfares.com. Very misleading and a terrible start to this trip.

Overall good. I was surprised how easy it was to get from plain to plain in such a short time. Food choices were not so great and quite expensive. Entertainment was ok. Flights were smooth.

Our three ski bags did not arrive and are still not delivered, one full day later. With one ski bag not traceable at all. I would not fly Iceland Air again.

Bad. Flights were late, by hours. No clear information was provided even until the delayed boarding time.

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

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

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.

I didn’t get a chance to experience anything because the 3rd party company that receives payment did a really bad job. After I received confirmation number I went to bed then I tried to check in my confirmation number did not work then I received a massage that my payment did not go through I called the company to rectify the problem and I was told that confirmation the whole thing was cancelled and that they couldn’t do anything about it and hang up the phone. So I decided to purchase a new ticket from another airline. I will never use kayak again and I’ll make sure all the people in my circle doesn’t deal with you guys.
