The flight itself was fine, even with a one-hour delay leaving on the Reykjavik tarmac (the lost time was made up during flight). Our experience at the Reykjavik airport on arrival was terrible due mostly to the one hour it took for passport control. Only two stations were open for our category, and the room was full with a huge crowd.

Our experience at the Reykjavik airport on arrival was terrible due mostly to the one hour it took for passport control. Only two stations were open for our category, and the room was full with a huge crowd.

Awful. The Iceland airport was a complete mess. Boarding was a chaotic, the seats were awful, there was a group of rowdy 20 something men in our row hooting and hollering, ordering alcoholic drink after drink. Yelling and laughing at the top of their lungs and the crew just went along with it. Passengers complained to the men, asking if they could keep it down (it was a night time flight so people wanted to sleep). They never listened crew continued to laugh with them, flirt with them and serve them more drinks. No free food or snacks, seats were horribly uncomfortable. Worst flight I've had in a long time

At least one soda free, felt like I was nickeled to death.

Friendly flight crew. Airplane (757) configured as a domestic flight (no lie-flat seats) & no advanced meal selection.

Was a bit surprised that Icelandair flies a domestically configured 757s on long-haul flights to Iceland (no lie-flat seats in business class).

The Icelandair crew was so kind!!! Thank you for making my first trip to Paris a great one!

I am not going to fillo this out for each leg of my trip. My first review holds for the experience

The movie choices were poor. The worst problem is the treatment of passengers durinng pre-boarding. In one case the primes were checked in and sent down the boarding tunnek only to stand waiting there while the plane is cleaned. In the second case the bus was loaded, the doors closed and just stood there unmoving like sardeines in a tin for over TEN minutes. In both cases it was rough on us old guys who find standing for long periods trying.. In other words, Donnt just stack us up and forget us.

Screen didn't work, and neither did the button to tilt the seat even though the seat was comfortable

The most uncomfortable seat i’ve ever had on a flight
