More complimentary drinks, like soft drinks.
J
10.0 Wonderful
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.
C
10.0 Wonderful
Smooth efficient airline. Think they should have their own bag drop as the queue took 30mins to bmscan and drop
A
8.0 Very Good
Good. Lacking overhead bin space. No food offered but you can order online or in flight and pay for snacks.
A
2.0 Poor
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.
M
10.0 Wonderful
The flights were in time and the bags arrived. well done
A
2.0 Poor
Only serving 2 small coffee in 7.5 hrs flight with very limited choice to order food.
D
2.0 Poor
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.
A
6.0 Okay
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.
M
6.0 Okay
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.
