Good. Lacking overhead bin space. No food offered but you can order online or in flight and pay for snacks.

The flights were in time and the bags arrived. well done

Only serving 2 small coffee in 7.5 hrs flight with very limited choice to order food.

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.

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.

Horrible. The flight was delayed by over 3 hours but updates were barely provided. Boarding started 3 hours late then stopped because their system crashed. So now, passengers were standing for 15 minutes in the open waiting to get boarding passes scanned and get on a bus. Duty-free closed around 4-4:30. Only 1 food outlet was open and it was super slow and busy since it was serving passengers from multiple flights. So a number of passengers couldn't buy meals at the terminal. Since the flight was delayed by over 3 hours, we could have been offered snacks on-board. Nothing. The seats barely reclined. In-flight entertainment options were pitiful. Overall, a miserable experience. Never flying on Icelandair ever again. :(

Bad. Flights were late, by hours. No clear information was provided even until the delayed boarding time.

Again, lines for boarding are a problem in iceland. The flight itself was fine and very smooth. No complaints. We would definitely fly icelandair again.

Had a screaming child next to us. Not the airline’s fault but still annoying.

Highly disorganized company, poor customer service. Packed seats on a 737 for a trans-atlantic 9 hour flight. Greedy company policies, no meal or snack provided for 9 hour flight.

Experience was good. Could have been better if we didn’t have to board an hour before the flight to ghana and miss relaxing time in the lounge. That process was very stressful

Boarding crew is unfriendly as i was asked to handover carryon luggage too upto final destination Bangalore I was not prepared for that and i had to travel without my diabetic and hypertension medicines

I was charged fees for check in bags at the airport by British Airways. It was supposed to be no charge but Kayak messed up my booking apparently and I had to pay for check in bags. I paid $175.

They took my carry on and checked it in. Staff in general at Heathrow are not friendly or helpful

The crew were professional and friendly. It was the most uncomfortable international flight I've ever flown. Crammed in passengers. No overhead space to put my bag. No leg room and unable to recline seat due to seats too close together so it upset passenger behind me! Upgrade price to get 2 inches of more space unreasonable.

Boarding in Dallas was hell with extremely rude gate agents , especially a lady named Rajathi who was the epitome of rudeness with no compassion at all . She was horrible and I wonder why airlines have people like her on their roster who exude arrogance and haughtiness . Will probably not fly British Airwsys because of people like her .

Less than average, low level of shared required information needed during the transfer from airport to another, also the used team during boarding In Indianapolis station is Not Professional

Food was average. Better headphones seats were average at best.

Nice flight. Legroom was good. Food was good. Staff was friendly and helpful. Plane was modern and clean. Seats and headrests were comfortable. Entertainment system was good and modern, with a bright LCD screen and many appealing choices.

I have something to say about the flight I took from London to Gothenburg, after my flight from Austin to London. I fly a lot and have done so for decades. I first flew to Scandinavia in 1973. My former wife is Norwegian. The main thing was the experience at the Gothenburg airport. Three flights from Britain arrived around the same time. So there were huge lines at immigration since Brits are no longer a part of the EU. After over an hour in line, I finally gave my passport to the immigrations man. You’d have thought I was an Afghan. I just barely got into Sweden. I had to answer all kinds of blunt questions. I had to show all kinds of onward tickets, addresses of places I’d be staying and it was pretty daunting. Perhaps it has to do with the situation with Russia. British Air might have done something to prepare people that things have changed a lot and they’d better be ready to run the gauntlet when trying to get into the country here. Thanks for listening and taking this into consideration. Sincerely, a senior citizen of the USA
