Although the flight was delayed the crew and the flight itself were very good. Couldn't fault anything and after the disappointment of being abandoned in the US by BA it was a welcome relief to travel with United

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

The seat and leg room was not good. The food and beverage service was good.

Liked fold flat bed. Didn’t like having no window. Didn’t like poor choice of food and being served dinner very late, hours after take off of a 7:40pm flight. Servers not friendly. Food horrible in business class.

For economy, it was very good. Staff was great, they even let some of us change seats for more leg room... Put an empty seat between us which was fantastic for a 12hr flight. Onboard entertainment was excellent, I think over 200 choices of movies/tv/etc The bad was the barely/nonfunctional wifi that cost either $16.99 or 1700 miles (full flight). It was atrocious... Definitely the worst of the last 3 long haul major airlines I was on the last few months.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

Flight was full, and would have preferred an aisle seat, but due to getting a late ticket ,the seat I had was adequate. The flight crew were very help full and hard working. Food and drink were excellent for the 11hr flight. Overall I was pleased with flight, and would recommend British Airways again.

More choices on menu. Seemed only thing offered was Scottish, and while that’s good for the Scot’s it doesn’t help the Americans who don’t like that food. And I really hate it when, during sleep time the attendants have a very loud conversation right over you. Lastly, I paid 5000 dollars for business class, and having to pay more to choose my seat early is really an insult. Seems greedy

The chicken adobo was a little too spicy but good otherwise. My personal opinion. Movie selection could be improved, too many horror movies. Could add a few more chick flicks! The flight was bumpy at times. We arrived a little early too! Flight attendants friendly.

Again flight was awesome except British Airways lost both gate checked luggage’s. Still missing

really bad they refused to check in luggages that I had purchased, even showing them the transaction receipt from british airways app the staff in miami was MEDIOCRE

Crew was great and responsive. Entertainment quit working with about 4 hours remaining on the flight. My seat cushion was broken.

Not very good , the stewardess were unfriendly and they don't like to be bothered. Cos was a night flight and they need to sleep.

British Airways staff are very polite and willing to help.

This particular flight wasn't very full at the back, so there were three seats available for spreading out and getting relatively comfortable

Everything was good. Only issue comes from being vegan and flying. The food options are super limited.

Overall good for an economy fare. IMO the movie selection could be improved. Great that you can now connect bluetooth headphones to the entertainment system.

Paid for a Premium seat...minimal recline, no footrest. Maybe slightly wider than a cheap economy seat. Zero chance of getting any rest on this plane

Comfort of seats is not good. Like sitting on a rock for 6 hours. Also no in flight food and limited beverages unless you pay is not nice. Need flight to be dark during the “night” but attendants don’t ask for shades to be lowered..

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

Iceland airlines doesn't provide any meal on flight to and from New York, except water and soda. Airline over charge for checking in luggage. I'm really upset. If there is option to use another company, I suggest to other people use them.

The seats on this airline are sooo small, even for a petite person. I felt like the seat tilted forward and I was fighting to stay in it. The lavatory is horribly small, with a wet floor because the sink is so small you can't help but splash the water all over when washing up.

Smooth efficient airline. Think they should have their own bag drop as the queue took 30mins to bmscan and drop

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

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.

Moved the flight an hour later, were not reliable about confirmation, website didn't work, no gate information, boarding was a mad house. Flight itself was fine and short. Organization needs work.

The app on phone and the online check in is not good, it would not give me the option of Spain or Madrid City in the drop down menu and I couldn't move forward with online check in.

Flight was delayed 3 hours and 15 minutes. The delay caused me to miss my tour group due to arriving late.

As always a terrible experience. AA stole a day from my vacation days planned to be spent with my Family. Response: delays related to weather issues.

It was a wonderful experience with great food, great staff, and no difficulties boarding!

Paid for my seat 4 months ago. Did not pay the extra for specific seat assignment ( never have and never was a problem). Could not electronically check in (found out it was due to overbooking and that unassigned seats get bumped first - never happened to me before). Luckily, did make the flight. Very stressful - would have been extremely disruptive for my travel plans. UK Visa - never notified by Kayak or BA that a visa was required. Had to spend 15 minutes to download and complete app at the flight counter and pay $25, and was told they would let me know in 3 days if I would get it (flight landing in 10 hours from when I completed app). Luckily, visa was approved before landing. Unnecessary stress created here. Food - main meal, curry chicken barely palatable with unrecognizable vegetable. Desert cup, cheesecake, also barely palatable. Salad cup was good. Small water offered only 3 times (before main meal, at main meal, at morning snack) - not nearly enough for long flight.

From boarding, to attention in flight, I couldn’t fault it.

Not having to check carry on bags when plane wasn’t full. (The told us it was)

I was in business class for the 8 hour flight where: 1. The WiFi did not work 2. The entertainment system did not work 3. We were told there were no hot drinks for the entire flight

I had an issue with the name on my ticket vs my passport name. I was very upset that the Iberia ticket clerk had no authorization to help me and I was left to fix it. It took 19 calls of persons promising to accomplish and not doing anything before I reached someone who helped me in 10 minutes. Two of them even hung up on me. I missed my original flight because of this. Terrible customer service.

Flight was good but seat in 12D was not comfortable, better on the Airbus 321 from Tampa to Charlotte. No breakfast was served before landing in zLonfon only a coffee and orange juice.

I was transferred to an American Airlines flight. The boarding was late and unorganized. The seating was extremely tight and uncomfortable. Will not use AA again.

The entertainment selection was ok, but overall not bad! The crew was great.

Good crew and boarding process. Horrible food and one of the most uncomfortable aircraft seats I have ever sat in. The cabin temperature was warm which made it hard for my family to sleep.

The check-in of my luggage was terrible. When purchased my tickets, one luggage and one carry-on was part of the fight. My flight was switched from British to American Airline. During check-in of luggage at the airport, I was denied and had to pay extra $75. How do I get reimbursed for this extra luggage payment?

More Indian vegetarian food options would have been better Availability of seat selection free of charge 72 hours before departure would be great

This was the second time on BA, food terrible, bathrooms gross,( granted, that was mostly due to the disgusting children urinating all over it)boarding was late and disorganized. No gate issued until last minute st Heathrow, bad system, caused undue stress. Seats were painful, that's what you get for traveling like a poor in economy, right BA? Should have been able to afford business or first class if you want to actually be able to walk upright without back pain after a trip.

This was the second time on BA, food terrible, bathrooms gross, boarding late and disorganized. No gate issued until last minute st Heathrow, bad system, caused undue stress.

The flight was delayed twice and because of that, we missed our connecting flight. British Airways then attempted to put us on the last flight to Milan from London which would have kept us in the airport for 12 hours. We had to speak to several levels of bureaucracy until BA management let us fly on a flight that only kept us in the airport for two hours. If there was an earlier flight, why weren’t we put on that flight from the start? Unacceptable behavior from what was once my favorite carrier.

The payment system was not working so was unable to connect wifi the entire flight
