Vegetarian food option was very poor. Effectively, overcooked rice ("risotto"). Zero protein which is always disappointing with no vegetables and poorly seasoned. Basically had lots of carbs on 6-hour flight. Not acceptable for business class in 2026. Flight was otherwise very good.

Vegetarian food option was very poor. Effectively, overcooked rice ("risotto"). Zero protein which is always disappointing with no vegetables and poorly seasoned. Basically had lots of carbs on 6-hour flight. Not acceptable for business class in 2026. Flight was otherwise very good.

Small plane. Tight seating . What can one say except that it was fast!

Caring & friendly crew. Most important: got us SAFELY to our destination!

I sat in the first row behind first class. There was plenty of legroom. The entertainment was great. I saw two excellent movies and one episode of a sitcom. Also enjoyed the flight tracker.

OK overall. Flight was delayed Crew on flight was good

On time, only a little turbulence, very competent and caring attendants. Clear information.

Late late late. Delayed and arrived an hour late for a 1 hour 45 minute connection. Every time. Poor record for this company. I try to fly any other carrier first.

The flights are literally always delayed arriving, boarding and taking off so they are always late for the connection. I planned ahead so I was okay but many others aren't. The food was terrible. The staff was very pleasant. I appreciate boarding back to front.

The crew was friendly. The plane was comfortable. In-flight wifi didn't work well at all. The ride was quite turbulent but understandable given the weather.

My issue is with the SkyWest terminal. The flight was not listed on the main airport flight screen list, and I had to do a Google search to locate the terminal and gate. We had to ask several airport employees where to locate the phantom gate. The airport did not provide adequate signage and was confusing. When we arrived, there was one vendor providing services that quickly closed, leaving zero options for food and drink while we waited hours for our delayed flight. The crew that assisted with check-in and boarding was VERY friendly.

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.

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).

When you consider the price I ended up paying for everything. This was not a good deal! I had no idea that this airline had changed to a bargain basement no frills airline. So, it was disappointing to have to pay for every little thing. The only thing included was water and coffee. You have to pay for everything else! So I just felt nickel and dime.

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.

I had no idea that my ticket only paid for my right to get on the plane. They charged me $130 for my carry-on bag because it was 1 inch too big she claimed but it wasn’t! Then they wanted another fee for everything. I had no idea that Icelandair had changed to such a bargain basement airline. I was very disappointed.

I flew four flights on British Airways within two weeks. I was unable to download the boarding pass to my phone for any of the four flights. I could check-in for my flight but the system would not give me boarding pass. I tried multiple ways and multiple times. I discovered many other passengers also had the same issue with their boarding passes. No explanation or acknowledgement by BA.

Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays

Because our ABZ-LHR flight was cancelled by BA for reasons they refuse to tell us--not weather--we did not make this flight and were booked on the following day. BA offered no assistance to us on the phone or in the airport, and we had to find a hotel at Heathrow on our own.

BA Canceled this flight and put us on a flight leaving Aberdeen at 8:00 PM, delaying our return to the states by a full day. The cancellation caused us expenses in both Aberdeen and London and BA was completely unhelpful on the phone and at the airport.

Horrible - flight was delayed by 6 hours - we boarded, were made to de-board due some technical fault; aircraft changed; special meals request on new flight - all went awry. Landed in Dulles airport; breezed thru immigration; as Business Class passengers or baggage was delivered almost 90 minutes after landing; air tags indicated the bags were just near the carousel but the unhelpful BA staff - Maria and Ghina refused to give any update - palming it off on some imaginary invisible “manager” despite air tags evidence showing it right there. So about 50-60 passengers waiting and getting infuriatingly impatient for their bags coz one container was not delivered. Finally after much argument by some other passengers Maria condescended to go to the “ramp” and within 5 minutes the baggage was delivered miraculously. Question is why couldn’t she have done it one hour earlier ? Poor poor experience once again on Business Class BA.

Cheap Flight Fares would not provide booking info. I canceled the reservation and we arbitrated with American Express. They provided erroneous info to Amex and it was determined that C.F.F. deserved the price of the ticket. Worse experience I've ever had.

Seating space is appalling. Seats and all surrounding area in "Economy" is built for individuals shorter than 4' 10" and below 120 lbs. Ridiculous. While I'm not expecting fine dining, the food was the worst airplane food that I can recall.

Business class lounge for my gate was closed and no email was sent, causing me to walk back and forth to different gates, etc for over 20 minutes one way. Flight entertainment was mediocre with very poor choices especially for business class cabin. Original flight was cancelled and rebooking was difficult and no reason given for cancellation.

Very comfortable flight and simple and directed one way and back. Amazing price.

We loved our flight attendant, Emma from Scotland, the meal and entertainment offerings were wonderful, the flight was smooth, and enough leg room to stretch. We would fly with you again!
