Pros: The in-flight entertainment system is very good (once you get past the spam video ads for Icelandic attractions). The flight crew on both flights was very attentive and friendly. I really appreciate that IcelandAir gives out toy boxes to the children on the plane; that's very nice.

Cons: My first flight was over 50 minutes late. Since I only had 1 hour and 5 minutes to begin with to catch my connecting flight, this forced me and several other passengers to do a mad sprint through Kevlavik Airport. We made it to the gate drenched in sweat and gasping for air - not a pleasant experience. There was also no time to use the airport restrooms or refill my water bottle. The cabin crew on the first flight completely ignored the fact that we were this late - there were no announcements about flight connections, or even an update as to that we were running behind at all. This should have been handled very differently. (Also, general pet peeve: They give you no food whatsoever, even for transatlantic flights, and they do not make you aware of this prior to being on the airplane. If you want to eat, you have to purchase their overpriced airplane food from the menu.)

Pros: The crew was friendly and attentive.

Cons: On our outgoing flight we believe they changed the type of plane because we ended up with extra legroom seats which was nice but they made us pay for them. Since I was flying home alone, I did order an extra legroom seat and they tried to make me pay again at check in, even though I had my receipt.

Pros: We were a little delayed, so I read my book. Not for long though as I was really tired after my flight from Los Angeles. I fell asleep right after take-off and didn't wake until we landed. Best way to fly :-)

Cons: Very little legroom for a 6'1" guy. Would have liked a bit more space, but I guess I was too tired to let it bug me.

Okay 4.6

Cons: I arrived 13 hours late, had two extra flights. I was delayed 3 hours first flight, 1.5 hours second flight after watching two flights that I “wasn’t allowed” to be on depart right in front of me at 9 and 10 instead of the 11 that they rebooked me on. Once I landed in Lisbon after the second flight that o wasn’t supposed to take. We missed the connection by 5 minutes and there were many people flying to my same destination. I had to wait 5 hours in Lisbon when I shouldn’t have ever went to Lisbon. I bought a ticket from Newark to Zürich through Porto 10 hours in total. I think TAP overbooked everyone and seated us on purpose. The secondflight was delayed due to “bad weather” and it was perfectly nice outside. Shame on TAP. I’m sure other people are complaining.

Mediocre 3.3

Pros: It was a rather empty flight so I was able to have space to myself to stretch out.

Cons: Everything. We were late boarding, late taking off, micromanaged by the crew like we’re stupid, the food was truly god awful atrocious... and there were like 20 movies to choose from for a 7 hour flight. Furthermore, there were NO snacks available for purchase so you were forced to eat gross food.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
