We had a great experience with Icelandair. Boarding was efficient and easy. The flight crew was friendly and helpful. We’ll travel with Icelandair again anytime.

Paid for seat upgrade that didn’t happen. Large luggage charge. No food or snacks without paying extra. Tight seats - even on row 11.

Damage May baggage and I report the airport agant and they see it

The food service is confusing. It was not immediately apparent which beverages were complimentary, if any.

I’m considering never flying with Iceland Air again. The seats in economy are torture. Now you only get water, coffee and tea for free- really? No food, not a single peanut. The passport line was insane, everyone was worried about catching their connecting flight. This was the third time I’ve barely made my connection, had to run. It can’t be that my choice is to use the bathroom (during the 50 minutes between flights) or make my flight. SO stressful! Ugh.

Service was excellent. Food and drinks were very good except for a greasy lump of a donut at the end of the flight that left us both feeling internally disgusted.

For a four hour flight, I was disappointed that everything was for purchase except for coffee, tea, or water. The disembarking in Iceland was so inefficient and time-consuming. We landed and stopped in the middle of the tarmac, had to disembark in the rain, and then squeeze into a bus which took us to the airport. Crazy! How does that work in winter?

Travelling with a 2 year old and being seated at the last row right by the toilet was the worst experience I had in a long time. Please do better for other parents

So Iceland Air is one step above Spirit Airlines. They do not feed you unless you pay for it or are in Saga Class. So, bring your food. They have a drink service, but it's in a large Dixie cup. Ask for the can, that is the only way you'll get a real drink. Also, we missed our connecting flight so they put us up in a flea-bag motel. Don't get me wrong, the staff was nice and friendly, however, there was no shower gel or shampoo in the hotel. We have to go to the corner store to pick some up. The room was not in great shape. Holes in the bathroom, a badly repaired ceiling in the room. The window was warn out. So, you get the just of how bad it was.

on plane service was excellent - we flew business class. And everything ran on schedule - always a good thing. However, the transfer is Reykyavik - both going and coming - was really crowded and confusing. It's tough enough when you're tired from a long flight - but then to push through heavy crowds to get on to a shuttle bus seems like they don't have the facilities to support the numbers.

There was no entertainment or food service (short flight). The flight was delayed more than an hour.

Horrible airport ever. We stood in the security check line for more than an hour. It was past boarding time and we were still waiting in line for the security check. With 2 children and a medically ill person we had a very stressful transit.

Cancelled - booked on train; and then flights started running! I spent 5 hours with 2 changes on train while flights started and is 50 min

Lufthansa has a bag policy unique to Lufthansa. We all had a small carry on and a backpack (personal item) that we carried with us through multiple other connecting flights, no problem. With Lufthansa we were charged 80 euros each for the carry on at the gate, for this one flight. When asked they said they made an announcement… problem being that we had just arrived to the gate from a connecting flight and didn’t hear an announcement. While we were standing at the counter paying the ridiculous fee several other people were stopped, while countless others boarded with the same type of luggage and were not stopped. Crazy. Good news though, when we got on the plane half of the overhead bins were empty! After an already horrible experience the lady at the counter was also terrible, so that helped round things out.

We missed our connecting flight in Frankfurt do to security and all hell ensued then.we got rebooked to Washington got there round 10 am ish didn't find out till 630 we were rerouted to United!! Then we started getting updates

Boarding arrangement at Frankfurt was terribly managed with no proper guidance and the flight was parked far away from the gate. In flight entertainment device (touch screen) was not working at all throughout the flight. And on top of all this two of the checked in bags were found to be missing when we landed at Chennai. All this mismanagement at a very high fare of about $2300 per ticket is unacceptable.

Water in bottle and a piece of chocolate were given. We did have movies to watch.

Too tight connection. Lufthansa staff pulled 12 of us out of passport control that had tight connections and took us about 1/3 mile AWAY from our gates and put us in another slow, long line. Needless to say all of us missed our flights and the Customer “Service” staff was rude and not helpful at all. Was rebooked from a direct flight to one w a 6hr layover. Asked about an other option that was on my app and was told to book it myself online (which would be $300 extra pp!!). Got rebooked again w a tight connection which was also missed. Rebooked into middle seats that didn’t recline for 9 hr flight!! No compensation (and we paid for seats!) Ended up taking 26hrs to get home from Europe to North Carolina! No longer a fan of Lufthansa—2nd time having these kind of issues w them!

Good but I don’t received my bags yet is been 5days still no update

The food on this flight was better than what we had getting to Rome. The flight was comfortable and the staff was great. One of the staff members was a stickler about the blankets in the aisle, which I get, but still. Overall, great flight and will fly with them again!
