Airline reviews

Our flight from JFK to Madrid was delayed. We had to go from one side of the Madrid airport (Terminal 4s to the far end of terminal 4 - Gate K98) to our gate in less than 30 minutes. Put passport control and security/baggage check and that’s very hard unless you’re Usain Bolt. I called Iberia Airlines and the telephone customer service told me that I was going to have to pay to re-book. Luckily the help desk in the airport (who was dealing with dozens of people from the same JFK-Madrid flight) did not charge us extra to reschedule to a flight 8 hours later. They also gave us a voucher for breakfast and lunch. Glad the actual person at the airport had some actual sense.

For an long range economy flight I feel more space and more meal options need to be offered for flights over 5 hours

Take-off delayed an hour because of a missing flight officer, so,arrived in Charlotte lates causing many passengers to miss connections. Otherwise a very good flight, safe and comfortable, with an excellent professional crew.

The flight from LA to Chicago was smooth and service was very good overall.

B-class on an old plane with antiquated amenities and poor service. Landed in Rome w/o bag that didn’t make the connection (plenty of time in London). Bag will come to hotel NOT the day it lands but the following night!! Still waiting for bag…BA had nothing to offer in support and couldn’t even tell me their comp, told to submit receipts and then I’ll learn what is or isn’t covered.

Ontario airport boarding was very easy to park and access, is clean and TSA took 10 minutes total. Check-in was a breeze and cruise was very nice.

It's a long flight and that is always difficult. I was comfortable and well. The movies available were great and the crew was good.

Premium Economy Good crew, good service, excellent food. Seat back screen just not bright enough.

The crew was very attentive through out the flight. Seats were comfortable, nice flight bag with pillow and blanket. Food was okay, since it was a overnight flight seemed to go by fast.

Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

Couldn’t get boarding passes online, delayed an hour, and smallest amount of space on board I’ve ever encountered for such a long flight.

I’m an Iberia fan but this time They dropped the ball. I went from ALC to MAD to LHR. Boarding in ALC was by group… to get you in a bus. Then we sat for almost an hour when most people had connections. When we landed in Madrid we did so and they put us in another bus almost like if they wanted to make people lose their connection. We made ours by the skin of our teeth but our luggage did not. And on top of this we had to listen to the pilot bragging about Iberia being punctual. To be true we made it on time to LHR but we are Still waiting for our luggage

I have to compare it to the AA flight back home. AA was a little better. Perhaps it was that American English is my native tongue. My seat on AA was newer and more comfortable. The food was a little better. The entertainment was much better, more movies worth watching. The sound was lousy on both.

Excellent liked business class except wife’s luggage was lost on 10 Hours connecting flight to Miami and we were priority! 1:20 layover! Expect better From American Airlines partner

Service was good , communication and emails were in Spanish though I booked in English , end up figuring it out but also flight was partnered with air maroc and I had to call them to check on not Iberea doesn’t make sense

In general, I've had excellent experiences with Iberia flights and will continue to use them. In this last flight there were two things that didn't go right. I didn't get the kosher meal I had pre-requested when I had checked in on-line. Things worked out OK as we ended up eating the fish and vegetarian choices, which were really good. The other issue was that some movies for me and my wife started fine but after 8-12 minutes the content just switched to something else. The flight attendant reset our entertainment systems, but the problem persisted. We ended up choosing other movies/TV shows that did work fine.

Awful. They didn't even show concern that her connecting flight( Dallas to Mardrid) was gone/missing. I don't understand how that is even possible. Rudest answer from one of the crew was that American Airlines sold the tickets to somebody else. My daughter was not in the list.

The flight was canceled on a Thursday last minute. I lost thousands of dollars in hotels and car rental

Excellent lie flat seat for premium economy! Great staff. Bad food . Not so great entertainment. My bag didn’t make it either.

Really like the idea experience on this airline I will use again
