I DO NOT recommend Iceland air...missed connecting flight.....paid for isle seat upgrade for health reasons...had to do that over....baggage left in the rain so clothes got soaked other items ruined....called customer * dont care* service

The ticket was reserved in my name but not paid for by underpricer. Alaska airlines was unable to issue my ticket (could not connect the ticket with the PNR) due to an error with underpricer and I spent the better part of 2 hours at the ticket counter trying to rectify.

Damage May baggage and I report the airport agant and they see it

Crew was very friendly. Need lay flat beds! More snacks

Good. Rxception is the Entertainment - movies and TV shows all out of date…

I liked the crew but not the uncomfortable seats and lack of movie and tv selection.

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

Seats in premier saga class were narrow and hard. Very uncomfortable for a 5-hour flight.

My experience with Icelandair was just ok, nothing special. Requested wheelchair service for my wife and none was offered at checking in Baltimore or available for her upon arrival at Gatwick airport in London.

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

As I remember my last BA flight - mediocre at best. Uncomfortable with poor and minimal food and drinks. Screen broke shortly into flight so didn’t have access to entertainment either.

They gave away my business class seat. No explanation and no apology. Told me I had to take the downgrade if I wanted to get to India. Then no WiFi for 10 hours. Just ridiculous. We should not work with this company at Deloitte. They don’t know how to run a business.

Work being done at DIA made it difficult to find BA desk.

The airplane was refreshingly silent in flight than Airbuses, landing was very soft and secure. Food was also warm and light , not a big fan of curry though. Staff was polite, discrete, professional and helpful.

I was booked in Premium Economy and never given a chance to choose to purchase my own seat. Ended up with a middle seat, which was very difficult for me. The airline then left my bag in London so when I arrived in Instanbul it was not there. They delivered it to me the next day but many valuable items had been stolen. I've been flying with BA for years and this was the first time I had such a bizarre and bad experience with them.

Meh. Lived the seat. The entertainment unit did not work and had to be reset 3 times. Service was SLOW taking over 90 min to be served. Crew forgot about my meal. Chicken was dry and almost inedible.

Boarding process was chaotic. Confusion over Boarding gates: gate 55 or gate 56 ???. Unnecessary standing in long lines to board. Better to call out Boarding groups one at a time and everyone else to sit. Airline only has 2 Boarding groups 1-3 and 4-9. That causes over crowding and chaos

Economy seats felt more cramped than other flights we have taken.7 hr, painful sitting hours 6 and 7. Web site difficult to deal with. Originally put in for 1 special meal due to type 2. Meal was awful. Tried to change selection to standard for return flight, on app and website, unable to complete that action.

flight was delayed from BWI to London - missed my connecting flight & then connecting flight (also British Air) was delayed - food is awful, TV & movie selection is great

We missed the flight to Barcelona because the flight from Baltimore was delayed. We flew on Vueling VW6653. Our luggage didn’t arrive. Please help us get our luggage. We are staying at Hotel Gran Via in Barcelona
