Crew were professional and responsive. Food was mediocre and breakfast could do with revampinmg

Food was very ordinary for premium economy, very small portions.

i dont know WHY they call it business class. the seats are NOT significantly wider than economy seats, they just do not let the middle seats be beepked to give the illusion of more space between passengers. the seats do NOT recline any more than economy seats either. the only real difference is the full meal served to business (vs none for economy). I would rather have a wider, lie flat ACTUAL business class seat with no food for a 3 hr flight. this was pretty disappointing to say the least.

There wore nice leather like sits, in my opinion seats lay out bit tight . Crew was great they did averything possible to make averywone comfortable as possible, food was, think worst I ever head on flight, head chicken and yellow rice. Ice cream was a nic treat.

Our previous flight was delayed but they waited for us to board.

Flight was delayed, short time connection to next flight but we make it, service was good, worth to fly just to try thair on board blueberry juce. Eccelent communication with airline.

My American Airlines flight was deleted and you guys never let me know

The entertainment system did not work. And we waited 45 minutes in our seats after we landed before we got to the gate

It was a pleasure definitely going with Iberia on my future travels

Our connecting flight was cancelled and it took us 15 hours to reach our destination.

David went above and beyond to make our flight the best that it could be

No food service almost missed because of first flight delays

Had a hard time finding my assigned seat. No attendants to assist.

The negative was the wait at the airport coming back. I checked my bags in, an hour before boarding and I get the notification that my flight was delayed. Rather had gotten the notification while I was at the hotel. Then it was delayed 3 x’s. Ugh!

Plane still had screens for watching movies. Good selection too.

Ground staff were excellent They helped to re book when our flight was canceled

Overall good flight. The pilots were excellent. It was a nice flight, but the seats were a little uncomfortable.

There was no air on the plane and it was very hot.

The free snack options are pretty pitiful for a 2.40h flight.

Good even though flight was delayed, the crew was prompt and efficient.

Flight attendant walked away once they landed and we were forced to wait another hour after an already 3hr delay.

No overhead space so all carryons were checked. No internet.

The flight was on time and everything went very smoothly.

A thousand choices for movies and nothing to watch. I avoid 'R' rated shows and others with violence and sexual content, which results in a handful of flicks to view and I have them already.

I think I paid for an extra legroom seat and to be honest, there was not a lot of space available for my not very long legs. The flight was totally full and the staff did everything possible to meet the needs of all passengers. My only concern was for the size and spacing of my seat.

Typically, I am always impressed with American personnel. These you run into the rude old hags that are still around. I can tell over my 40 years of flying with them, they have made strides in improving their attitudes.

Two issues. The plane was old and dirty. The armrest looked like an old car that had the vinyl rubbed off. The Seats in these aircraft are about as hard and uncomfortable. I want to tour Italy for a month and I want to buy a one-way ticket to Thailand but I will not sit in the seats these planes have. It is seriously stupid how hard they are.

The seat could not recline. This was not indicated as such when I paid for the seat. So itvwad not the most comfortable ride. At boarding, the staff could have more pleasant even though it may be an intense time.

The seat could not recline. This was not indicated as such when I paid for the seat. So itvwad not the most comfortable ride.

The meals were mediocre and the alcohol selection was poor.

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.

take snacks and food. purchase options in flight are not great

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.

Icelandair flight was excellent. The checkin and security arrangements for Saga Premium passengers at Newark was very poor - our checkin opened much later than the normal and our security queue simply led us to the back of the normal queue. Someone was having a laugh surely!

Never took flight. See previous comment on trip from Boston to Reykjavik. Used a different airline that i had to find and book.

The flight was on time and the crew was nice. I did not like the fact that my husband and I were seated in different rows. I feel pressured by airlines to pay more to choose our seats. We will sit anywhere, but we shouldn't have to pay to sit together. I also think they should serve at least a snack that's free.

One of the worst airlines I ever flew. Boarding is a disaster, they are always late, the planes are overly crowded. Everyone on my flight lost their connection because they were 2h late. Reykjavik is also not the best airport out there.

Been travelling for 2mo. And when you meet flight Attendants that love their jobs you can just tell. And makes flying with them worth another flight in the future!!

Everything was great! My only critique is 25 euro for wifi is wild, but I get it

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

My flight was delayed d the gate was never updated inside the terminal. If I hadn’t checked my email I would have missed my flight. Also, I paid a total of $5100 for my flight to be. Business or first class. My final leg of my flight from Heathrow to Frankfurt was not to standard of what I expected or experienced in the previous legs of my trip.

I requested a wheelchair for they haven’t got it, they are old and don’t speech english

The flight was ok, the flight attendants were lovely, the movies were good, the food was ok, and I am just sad because my luggage didn't arrive with me in Iasi because the flight from Vancouver to Frankfurt was delayed and then I barely made the rest of my flights. Also, there was no real support once I got off each of the flights. There was nobody to ask about gate or where to be and for example when I got off in Vienna to catch the flight to Iasi there was no screen where I could read the gate and time of departure of the plane. I was going crazy trying to find the plane to Iasi and I barely made it. When my luggage finally arrived home it was broken. The handle was completely broken and that was not so good. I am in a visit here, in Romania, and I will have to buy a new luggage.

They are professional. Nice crew. Still flying Boeing 747. Thank you for that. I love this airplane. Traditional.

Entertainment was good. Food was mediocre. Service was mediocre. New plane was smooth

I have ordered Hindu or Indian vegetarian food, to my surprise they did not find any such request. All I ate during the flight was 2 pieces of bread. The airline hostess was completely rude and racist. She promised one apple and I asked he four hours of promise and she denied saying am not nice to her. Europeans seems to be having racism issues with Indians. I will officially launch complaint with Indian and USA governments They made to starve, I recently got open heart surgery and I am diabetic patient

Service was okay. Food was okay. I selected a window seat in the 36th row and someone took it upon themself to change it to an aisle seat in the very last row!!!

Sorry, I’m not a fan of United. The seats are just too cramped and uncomfortable if you are traveling very far.

I am not sure I like the new Discover line of Lufthansa. I have been flying from us to Italy for the past 30 years and always favored Lufthansa ove other Companies because of cleanliness, service, food, beverage. When compared white other airlines Lufthansa was always considered one of the best. I can't say that anymore. I fly Lufthansa only because I consider the line MCO to FRA timely convenient for my schedule but always look for alternatives when before I was considering other routes only if the price was in question.
