My husband and I pre-ordered our food, but they did not have my husband’s order, and my cheese plate was very average. I asked for a blanket and was told they don’t carry blankets on domestic routs. The flight was on time and smooth!

My husband and I pre-ordered our food, but they did not have my husband’s order, and my cheese plate was very average. I asked for a blanket and was told they don’t carry blankets on domestic routs. The flight was on time and smooth!

There were delays on both ends. It made it less than excellent. This plane was great though

Everything was great except for the wifi was junk. Crew was super friendly and helpful

I wish that we wouldn't have to go through TSA again on connecting flights.

Attendants were rude. Scowling. Seats were miserable and we paid extra.

Somehow I got “offloaded” even though I had my boarding pass and was in transit Food is horrible Staff were nice and cheerful No headphones were provided on 11 hours flight

Fight crew was not very attentive and the bastions were gross!

Our flight was great we left Kona earlier and got into LAX almost an 1hour earlier as well. LAX AA is in repair so to get out and found our bus to get pick up was a bit confusing.

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

The staff were very helpful with lots of refreshments on offer. The toilets were clean. The seats were comfortable and entertainment was good. No complaints, it was excellent.

Food was low quality as well as quantity; I ordered vegetarian. We waited 35 MINUTES for the first bag to arrive after landing.

It was not Iberia. It was with United. It was great!!!

They offered several meals and snacks, the crew was very friendly and kind. There was a broad selection of movies, shows, and games. I was impressed!

My son and I are 193 cm tall. We had reserved and paid for seats with extra leg room towards the front of the cabin. The day of the flight, we learned that Iberia had changed aircraft. We were assigned regular seats way back in the cabin. When we landed from our first leg we spoke with agents at the gate and we were told that they couldn’t improve our seats because the flight was full.

I could change to business before flight and everything was perfect except for entertainment which was none.

Boarding process was chaotic and disorganized. The plane needs updating in the interior. Things are broken, worn out, and dated

My luggage never arrived in Miami; still waiting a day later.

Iberia personnel on the ground is so rude. I would think twice in the future before booking another Iberia flight

Seats, comfort level ugh. Crew was not attentive, only to coach

All corners have been cut and it’s a cheap experience that no longer is distinguished from most other cheap airlines

There was nothing to like besides the crew. The comfort of the airplane was poor (seat did not work properly and it was not comfortable). The “entertainment” system did not work! On a flight that last nearly eight hours, (which is advertised as having excellent entertainment options), that is unacceptable! Passengers should have been given free WiFi for the flight. The food served on the flight was below school lunch grade food. (With one exception, the ice cream snack). The chicken entree was tough and nearly impossible to cut and eat. The “pizza” served later in the flight was worse. The chicken pizza had a dry crust and the “toppings” were equally not enjoyable. The amount of chicken and cheese were almost non existent. Overall not a flight we would want to repeat!!

There was a problem in the luggage because there were not porters

2-1/2 hours on tarmac after arrival to DFW, lost connection to London, 3 hours wait for customer assistance, stayed on our own account in DFW, no replacement flight for 5 days, had to cancel the entire travel and return to Monterrey today.

My worst flying experience so far. This flight was delayed a total of 42 hours and diverted to New York before it was finally cancelled. It was delayed 4 and a half hours in London. As we were scanning our boarding passes at the gate they advised that the flight was being diverted to JFK since the delays caused us to missed the open hours for Charlotte international customs and immigration. We were assured multiple times by airport personnel, flight attendants, and the Pilot that we would land at JFK go through customs and immigration and then reboard the plane to fly to Charlotte in the same night. When we landed in New York the pilot advised us as we were retrieving our carry on luggage that we were delayed till 10am the next morning and to see guest services to get a room for the night. During this time I had to purchase a room for a family member in Charlotte which drove over 4 and a half hours to pick us up from Charlotte. This could have been avoided if American Airlines had been up front about the delay. Then after standing in line for over 2 and a half hours at guest services we were taken by taxi to a hotel 30 minutes out of the way. Luckily I looked for other flights that night and found one at 8 am to get on. The initial flight which we were scheduled to fly to charlotte in was delayed 12 more times and was finally cancelled 42 hours after it was supposed to land. I am unaware of what happened to the guest that were supposed to fly on the flight after we were placed on another flight but 42 hours in delays for a direct flight is absolutely ridiculous.

The boarding to Gatwick was a breeze but the boarding from Gatwick was a nightmare. The onboard service to Gatwick had a lot to be desired but the onboard sevice from Gatwick was amazing ! Very nice,friendly and funny ! Would I recommend BA to anyone.? ! Yes I would!

Is it American Airlines or British Airways? This is so confusing. I got it from Portugal.

Appreciate free wine and entertainment plus good meals. Also leg room

Really quick check in and security at Heathrow Terminal 5. Staff on board were lovely and very friendly. Could have provided a few more drinks on the flight but they were available at the back of the plane.

they are improving. The crew from Charlotte to Tampa was outstanding. SMILING and trying to be helpful with the customers.

It was a flight operated by Aer Linus for BA and the plane and crew were very good but the food selection was average.
