This airline is the worst I have ever encountered. We paid alot for our flights and had every issue we could have on our 2 flights, delays, sitting on the tarmac, running to the next gate, no food for allergies, no extra water given out during delays and no AC, little communication even less in English, rude service and missed connections with no rebooking.
This was all during the flight and now after our flights and 2 weeks without any updates on our bags it just gets worse and worse. Don't book with them it's not a one off and not worth the risk.

This is the second time I flew on Iberia. The first time was awful--difficult to check in, uncomfortable seats in premium economy and food that was not very good. This time, the flight was OK except the food, which was still not very good. Both my wife's and my bags were delayed. I got mine back 6 days later, but for inexplicable reasons, my wife's bag is still in Madrid 13 days later. I have called their "lost baggage service" every day for the last 12 days with no results. I have an airtag on the bag so I know that it is still in Madrid but now they are trying to tell me it is on a flight to London and then Phoenix. Don't fly Iberia--they have no organization at all. It is unfortunate they are part of One World--worst of the bunch.

Terrible experience.
My suitcase lock was broken and they stolen my goods.I bought a Santa Julia 2003 vintage port for my husband's birthday and they stolen it with other 2 expensive port wines.Also one of my suitcases hasn't arrived yet from Madrid.
Other terrible thing is they have filled the empty wine cases with someone else stolen jewellery box ( no jewellery, might have robbed someone else too).Please don't travel with Iberian Airlines.My first bad holiday travel experience !!!

They ruined our holidays.

First, even if I had seats, I was in a party of three and they oversold the flight, so me and my family had to travel in different flights

Then, for the second flight, they lost the bag. They can't tell where it is. This is a 45 flight in a flying helix can (72 passengers) from a tiny airport.to another small airport, yet they oversold the flight, and lost our luggage.

Every time I flew with Iberia, something happened (missed connection, flight cancelled or postponed). I wanted to give them one more try and again they disappointed me. Never again. Fly any other airline. Don't be sorry like me.

Worst airlines. I paid to select a seat that was impossible to sit comfortably in on an 8 hour flight!!!. There was a fixed metal bar and box in the seat before me. I submitted a complaint and asked for a refund that was denied. DONT FLY IBERIA
