I upgraded to economy plus and it’s so worth the price. The crew is exceptional and the food is pretty decent. I would definitely fly with them again.

I upgraded to economy plus and it’s so worth the price. The crew is exceptional and the food is pretty decent. I would definitely fly with them again.

They lost my luggage. Tromso in winter without warm clothes is not fun.

Flight was delayed 3 hours. Pilot cancelled flight under 4 people volunteered to change their seats to economy from business class.

I paid for wifi and it worked about a total of 5 min. Feel ripped off

Overall, this flight team did a fantastic job. They came often with the water, coffee and tea. There was no meal choice in coach, but the lasagna lunch was decent. The sandwich snack just before landing was tasty. The baggage bins were large, so no trouble holding carry on luggage.

My seat was not the one I paid for, the crew was very curt, and the cabin was extremely warm.

Old plane with terrible business class seats - good food and service. Boarding was a joke with business class boarding last.

Best airline to travel on a budget- really like their reasonably priced access to the SAS lounges where available.

The flight was cancelled early on and messed up the whole vacation and hard to get a refund from Kayak as they owned the ticket and of course they did not believe that SAS cancelled the ticket. Definite bad side to third party. SAS had rescheduled but overlapped the connecting flights. That did not work. Flight was cancelled long ago but Kayak still has it. Like it was taken? Bad IT ? Or all assumptions and no follow up which is the whole IT world. It needs to wake up and be more efficient. Especially as the world is going, there will be no freedom to do anything. And we will be living like the Middle Ages. Yeah, go read up on that while you still can.

Boarding the plane outside in the rain was a pain. Very safe flight

We were delayed bc ground crew gave the flight crew the wrong paperwork. We taxiied to the runway then back to the gate to get the correct paperwork that no one bothered reviewing the first time we pushed back. Boarding was rude and stressful like it always is. Gate agents and flight attendants are all over 55 years of age, embittered by years of underpayment From AA leading to their passive agressive bitchiness for no reason.

Was flying in premium eco and there were around 5-6 movies I wanted to watch and none of those could I play for some reasons. Not just me we checked w the person sitting next to me. Few of the movies were only playable :( Also that was not great that we couldn't upgrade to business however tried to, many times before the flight :(

Boarding time was easy & quick. Crew was excellent. In-flight entertainment was great/easy. Seats are too small and not enough room between rows: felt like a sardine/very cramped.

You cancelled my flight by email then made it very difficult to get in contact with you. Then put me in a flight with a long layover in Mexico returning to the wrong airport in uk. Mind blowing my stressful. I missed see my grand dad because of you.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

This was not the BA business class it used to be. Mediocre food, attendants seemed stretched thin. All the little luxuries that used to make BA business fun were missing. Flight delayed and the explanation given was they forgot to pick up crew - I hope I misheard! Transfer in LHR “sticky” - we thought we had way too much time at 3hours but it was needed. Next time will try different route.

Excellent- plan was barely populated. I cannot remember a flight where I was able/encouraged to stretch out!

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

Always getting updates by email very easy to check in on line. There was plenty of checking in staff to get you all through. It was nice that the flight attendants took time to talk to you and were interested in your holiday.

Flight from Phoenix to London was very quiet. Excellent space available for comfort, couldn't fault

The transatlantic flight was wonderful. The regional reminded me of jet blue. Crazy and packed. Not enough overhead space and tough on elderly.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Great hospitality and service! Seats are better cushioned then some

The vegan meal was pretty horrible tasting and the staff did not bring me breakfast and no coffee and asked. the connecting flight from dublin to bristol was much delayed.

Pretty darn good. Food was typical airline food. Not anyone’s favorite.

As four hour wait with no explanation as to why the delay Very unacceptable

My luggage was missing for 3 days. It’s not acceptable

Air Lingus flights were delayed on each of the three flights we took. Not a very good , and organized airline.

The family sitting beside me had a one year old constantly crying and another kid kicking my chair. I understand it’s nothing the airlines could do or it’s fault

The seating area was small and uncomfortable. The person in front of me put her seat back and my area got even smaller!!

Seats are way too much now with these new airplanes especially long flights like we had. I was 7 month pregnant and in a lot of discomfort due to small seats.

Food was horrible. This wasn’t business class. No leg space, can’t sleep in row position, huge delay

I liked how easy my transfers between flights in Keflavik were. I would have appreciated more food options in Keflavik.

The plane was flaming hot! Could not breathe. Everyone coughing from heat. Awful.

My biggest problem was the flight from KEF to DUB was delayed, which caused me to miss my connecting flight in DUB and we were forced into an unplanned 10-hour layover in DUB. Crew and boarding staff were all very friendly but this was a real inconvenience and especially uncomfortable for my disabled wife.

Not much! This was my first flight with Iceland air and unfortunately it wasn’t what I have expected. My luggage is lost nothing as of yet where it was left. Not a good service at all!!

The seat size was more like a domestic than an international flight. In fact, i would compare the ammenities, quality and service to a short hall ryan air flight, which was unexpected for an international flight. The plane was extremely hot so sleeping was difficult. My biggest complaint was that they are very strict on carry on luggage only allowing it to weigh 10kg/22lb. I try to limit myself to a carryon so i don't have to mess with bagage claim, but the wieght restriction made it impossible. I have never had a carry on weight restriction (at least enforced) on an international flight. Will not be including them in future searches.

Pros: "I liked the northern lights look after boarding upon introduction of the captain and crew members. Everyone was super personal and uninformed looked great. The best part was when they started boarding from the last row, which is the most logical and efficient way to do it"
Pros: "Got assisted to the plane by airport staff as I was in a wheelchair"
Cons: "Food on board was awful. Ordered hamburger but not availabe having already pre paid. Pizza was poor quality and had no taste. Range of food disappointing"
Pros: "The crew was friendly, the planes clean, flights on time. The blankets were a very nice touch."
Cons: "On my first flight, I paid for use of wifi, but it kept kicking me off the connection. Repeatedly, the entire time. On the second flight, there was no option for wifi at all. It would have been nice to pay for wifi once for use all the way to my destination."

The flight was delayed numerous times with inconsistent updates and very ambiguous information. When it was finally cancelled the logistics of handing out vouchers and rebooking was extremely chaotic. Meal vouchers were completely inadequate for the airport restaurants, and not even accepted at some. All-in-all, it was a very disappointing experience.

Terrible. The flight from Islamabad to London took 3 hours more then previously planned, I missed my connection to Chicago, and instead had to go New York, spend an extra day before arriving at my final destination. The return leg of the journey was similar. The connection time in Qatar was shrinked to less then an hour unannounced, I had to scramble to barely make it to my flight to Islamabad. Terrible experience, never using British airways again.

The crew on this flight were attentive, efficient and friendly. It really made for an enjoyable flight.

They canceled my flight , they put me on a different flight that was delayed and the connection was lost . They lost my luggage. And now I’m stuck with any of my belongings.

British Airways canceled our plane and gave us a new flight scheduled to leave in only three hours, so we had to drop everything and rush to the airport. The new itinerary only left us a one hour layover in Madrid, which was too short because the plane landed late and so we missed our connecting flight. We were then booked onto a flight scheduled to take off 8 hours later, and were not given any compensation or remedial measures.

Seat layout, flight/club attendant service, food variety and quality could have been better. Business class Standard is visibly low compared with 6 other airlines that we have traveled for the past two years.

Despite many attempts to work out a change, neither British Airways nor Kayak nor Chatdeal would allow us to cancel or change this flight so we lost all of the payments when we were not able to fly. Absolutely terrible customer service. We will never use either of the services again.

It said that there was wifi. During the flight there was no wifi and while waiting at the gate the phone services already got cut off so I wasn’t able to say I am taxiing from the gate to my husband. This left me with an uncomfortable feeling. So I was waiting on the WiFi connection during flight and that never happened.

Asked for a wheelchair multiple times. Got denied the wheelchair in London layover.

They sell 1h /1h30min connection ticket that are impossible to make
