I bought 3 tickets from Brussels to Santiago de Chile. I paid via transfer, at Iberia website. The money was out of my account immediately and the connection to Iberia website lost so I did not get confirmation of the tickets and no refund.
I had called, I had sent emails and no refund so far. The payment was done via Sofort (Ayden/Klarna) a recognized method by Iberia, you can not trust this airline anymore. Please pay a bit more instead of losing your money and time with them. I read they have plenty of court cases, mine will be the next.
I had travel a lot with many airlines, during many years, this is the first time I get this, and always there are issues with Iberia.

Had a flight from JFK to OVD by way of Madrid. The first flight was delayed by 3 hours and I missed my connection into OVD.

I then had to wait in line for two hours to book a new connecting flight, by which time I'd missed one option that would have been available if they weren't taking literally (I actually did the math here and there is no exaggeration) an average of twenty minutes per person in line.

I was then told that the only other flight for the entire rest of the day was already full, and booked on a flight for the next morning. I lost an entire day of vacation because of these incompetent fuсkwits and will never give them another penny.

Probably the rudest flight attendants I have ever met.
In Spain many people call this airline Ibirria. It’s a play on words that defines that this airline is crap. I tried not to fly with them as much as possible but every 4/5 years I have to.
In my last flight in Premium Economy I had to eat the economy meals because they only had fish in the menu. For any reason the catering only gave them this.
I reported and of course no answer. In another flight to Miami a fight attendant insulter me. I also reported and provided witnesses. Ibirria never responded to that even when I did follow up. I tried Internet. It never worked. New report, still waiting for a response.
Tip: Buy with Iberia more affordable tickets but in planes managed by American, more seat space, much better costumer service and any issue they respond.

My teenage son travelled to Spain with family friends. On arrival in Madrid it became apparent that his luggage had been lost. The paperwork for lost luggage was completed at the airport. The luggage was located still at Heathrow airport and was apparently put on the next flight to Madrid.
Over two days later he is still waiting for it to be delivered from Madrid airport. My friend contacted the airline to suggest she would collect it, which they agreed to. We were then notified that the courier had collected it and it would be delivered. After multiple phone calls to customer services we are no further forward. My son has medication that he needs. We have been lied to and mislead by the airline company. We have asked to speak to a supervisor and been obstructed from doing so.

I would not!! Recommend this airline if you like to keep your luggage!
Flew with them twice and both times the same issue occurred, my luggage was not put on the plane and left at the previous airport. The customer service when calling to receive my luggage back was lazy and slow. There was no contact back when MORE issues happened, they stuffed around with delivering the luggage once it arrived in the country delaying the process even more, ended up having to pick up the luggage myself! The lovely assistant at the airport (does not work for Iberia) mentioned this airline is known for taking bags off the flight due to weight restrictions, despite the fact I paid for checked luggage! I am extremely disappointed and exhausted from the lack of care from customer service!! Not worth flying again.
