Business class should have free wi-fi. Food was horrible

Business class should have free wi-fi. Food was horrible

Will never fly American Airlines business class again. Medicore service and very old aircraft.

Rude Iberia security crew at the Madrid terminal. No Iberia officials to be found to redress complaints at the gate. No supervisors. Nothing for processing upgrades at the gate Iberia app did not work to let me upgrade my options to higher classes. No water was offered on a hot day in Madrid. Madrid airport air conditioning was so weak that people were sweating. Never book on any airlines that codeshare with Iberia.

Do not use KAYAK or Finair for future travel. Unless you purchase the tickets directly from the airline, you were going to have a difficult time checking in. Kayak canceled my flights twice and ended up causing great difficulty in me getting back from Europe because they double sold my tickets between American Airlines and Finair. The event caused significant delays and led to me having to rebook my flights.

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

It was listed on my ticket as Finnair but there was no indication that the flight was Finnair. In fact the number was even different. There were no employees there until exactly 2 hours before so we had to wait in line at Iberia and hope

Flight ok, but me and other two passengers didn’t have connection with the entertainment in our seats. So, no movies, no games, no music… for 9 hours. The crew just told us that there’s nothing they can do but I noticed during the flight that there were empty seats, so they could have offered to us to change seats. Customer service could be better.

In-flight entertainment was. It working for the entire 12 hour flight! Unbelievable! At least provide free wi-fi so people could use their phones.

Check in was awful. Missed our flight because we waited to check our bags for over an hour. Only one or two agents available. Plan on 3+ hours if you fly out of Madrid. Won't use this airline again.

Takeoff delayed 2 hrs. Boarded on time to find we were missing part of the flight crew. Then informed that they had loaded too much fuel. Spent 1 1/2 hrs sitting there burning off the excess, which included a couple of laps around the runway until we were light enough to fly! Ridiculous!

Flight from Munich to O’Hare was great but it was on Lufthansa, a UA partner. It had more legroom than United, seat slid forward to make reclining more comfortable, they offered free drinks. United offered none of this. Oh and the food was superior to United’s which honestly, sucked.

Requested for warm or hot water because of throat pain, it was denied. The entertainment system was hung, requested the crew to turn it off, instead of turning it off they rebooted the device. It was stuck again, no one bothered to check.

Horrible on the chicago end. They change hates then there is a plane at the new gate so we can’t pull in. Then that plane has mechanical issue and needs to be pulled back to the gate but we can’t get to another new gate due the other plane being in the way. Horrible gate management which will cause many customers to miss connections.

Fantastic experience once again flying with United! There was great communication from the cockpit and one of the flight attendants went out of her way to get my two little kids some special treats which elevated our travel experience coming home.

The employees seemed impatient with their guests. It seemed like they were giving us orders, instead of easily assisting. Our flight was delayed waiting on a flight attendant. It was alright.

My easiest trip ever. Flights left on time, and came in a few minutes early. The flights weren’t full so it was very comfortable. Thank you United

Quinoa chocolate cookies are my favorite! Would be nice to have internet service like American

Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!

I flew from Barcelona to Chicago on UA yesterday. The flight was on time, the pilots did a great job and the flight attendants were super nice. All of them. Also food was good, and the drinks, including wine were served a few times during our flight. I highly recommend this airline.

I feel like the boarding process could be a little better. But the staff and everyone does a really great job.

Flight was good. Would be great if we had free WiFi

Flight was late, and not sure why. The business class lounge in Porto is not proprietary to TAP, and is really substandard, almost as bad as "The Lounge" in Boston. It was a D, which is better than the F experience in Bostonm where we left "The Lounge" for a better experience in the terminal. It had better food (an extremely low bar), ok beverages, and wasn't as crowded as the Boston one, but no restrooms. To use one, you had to leave and go downstairs. There's no down escalator, and the elevator might be able to crowd 4 people. Otherwise, you're carying your bags down the stairs. I hope the Lisbon club is better, but for TAP to provide this in the 2nd largest city in the home country is disappointing. They put out an announcement to proceed immediately to the gate, but there was no plane and few seats. from the lounge, 8 people with bags waited in line for the single tiny elevator. After almost an hour of standing, we finally boarded. TAP, at least on this plane, doesn't offer a welcome drink to business class passengers. Having said that, the crew was very friendly and accomodating. We landed about an hour late and then were told we were going to be on the runway for at least a half hour because no gate was available. So, bottom line, D- for pre boarding, A for flight attendents, B + for business class food, and Incomplete for post landing.

Special meal AVML was terrible Move selections were mediocre No Wi-Fi offered

We were delayed and they didn’t tell us why. There was no AC while we were on board waiting and it was very hot. We were in the last row and there was no window. We had a connecting international flight at JFK in a different terminal and the flight crew did not request passengers to let connecting flights off first and we almost missed our flight.

Flight was delayed more than 1.5 hours. Essentially no communication with passengers regarding how long the delay would last or any updates as to the delay.

Clearer signage at Lisbon Airport and more communication about delays

Flight smooth and on-time. Food a joke, crew humorless but efficient. Really a budget airline masquerading as a flagship, but it gets you there.

Overall ok experience as couple feedback: for improvement: 1. The vegetarian food was less and ran out, so many of us didn’t get it. Not all the crew member were polite and could be more hospitable.

Better leg room than expected in economy. Nice crew. Adequate bathrooms. Seat cushions a little thin, but recline well and have adjustable headrests. Best value. Liked having nonstop from ORD to Lisbon.

Excellent crew, food and service. Boarding via bus is always a pain but overall really good

The plane needs upgrading, the seats are uncomfortable, we are a family of three and they split us and did nothing to group us together, and the food is horrible compared to other airlines bu

Boarding was odd. Gates switched and had to take a bus to the plane. Luggage got lost. Still waiting on one bag. Flight itself was very nice!

I had a great experience , crew was great and enjoyed the entertainment options I will be booking my next International trip with them .

The flight was decent. I purchased my flight through Iberia, traveling with my elderly mother with mobility issues. I try to pay for luggage and seats online prior but Iberia website directs me to AA website. AA airlines website does not recognize the record locator. My mother and I are separated and each get a middle seat. She is seated the furthest away from a bathroom. I had to sit behind her to see her wave at me to use the bathroom. Lights out on the flight and I could not see her wave and she is not tech savvy to push an attendant button even though I showed her how. The attention to this detail puts AA at the bottom of my list when traveling with my elderly mother. Bad execution and handling when servicing those with extra needs due to mobility. I could not get her to the bathroom because she’s slow and she had to wait for me to get up from my middle seat then move her out of her middle seat. She had an accident which required that I hel her clean up before taking her back to her seat.

Horrible see last review they lost my bag had to sprint to gate no inflight wifi

They cancelled our NON_STOP flight from London to Chicago 22 hours before our flight. After a 2 hour phone call, they rescheduled us from London to Barcelona (Wrong way to USA) 2 hour lay over, and then to Chicago for a 9 1/2 hour flight at 6 am. Ruined 2 days of our vacation. We will not fly British Airways again.

Mediocre. I didntneat for more than 9h. Pregnant and diabetic. 0 care from The crew.

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

As compared to our beginning flight to Madrid this flight was light years better in every category! Highlights were the top notch crew, service and food. Our first experience with Iberia was at two opposite sides of the spectrum. Thank you for an excellent return flight to Chicago - O Hare!!

need more US friendly food options. Directions on getting to the next gate were terrible - resulted in long walks to the terminal and then finding I couldn;t enter there and had long walk back, then train to security then train back to where I started in the first place

Late lights, lost baggage and cramped seats. Did not feel that lost baggage was a priority. Communication was slow and often unclear.

I will never want to book with these people. They are arrogant and rude. Food was really really bad, crew was even worst

Check-in in SAN was long. ORD was good. Flight delayed On board crew was ok. No warmth or personality. LHrR barely made connection

Check-in experience, for business call please provide a premium experience

Everything. Employees offered to help me because I had to use a cane.

Unfortunately, my flight was cancelled because of some sort of emergency over the Atlantic and had to return to London. While I think British Airways made every effort to mitigate the situation, I must say it was still pretty unpleasant. I do appreciate the fact, however, that British Airways put my safety first…and I think the effort to correct a bad situation was very sincere. But I think the process might be handled better in future.

The seat pads are past there sell by date now and are uncomfotable. Also, with screens in the back of the seat, the seats shouldnt be able to recline as this puts rhe screen in your face.

As I have said it sucked, the ticket counter to have to find and pay for another airline to get home. Now I understand this happened over the weekend but they should have someone there to talk to us instead of throwing the regular crew under the bus.

Tv didn’t work till the last hour of the flight. Staff was rude and on a couple occasions was arguing with each other. Food was possible the worst I’ve had on a flight.
