I booked a saturday afternoon flight with Iberia. The price was appropriate - 40€. Board service bad, even for water you have to pay. The temperature in the cabin was terrible hot, it was hard to breathe, I felt like in sauna during whole flight. Flight had 30 minutes delay.

I think the strangest part of this flight was that two of our seats were relocated. I had arranged three seats together and one directly behind in an exit row. The seat on the aisle and the exit row were moved to the back of the plane. Good news is we still had seats with our kids.
Iberia is a good airline. I have flown them twice in Europe. They do a good job of giving great service to One World members.
Terminal 4 at Madrid which they dominate is incredible.

What an absolute disgrace of an airline. Some of the worst customer service we have ever received. The ticketing agents were rude, disparaging, and downright uninterested in helping us. The planes were extremely uncomfortable, the meals terrible, and the stewardess not nice or helpful. They charged us insane luggage fees (50Euro for first bag, 150Euro for 2nd bag). On top of that, they lost our luggage on a direct flight from Madrid back to Los Angeles, not even sure how that's possible? It's been two days now, and they haven't even contacted us.
You honestly couldn't pay me to use this airline again. Truly the worst.

This has got to be the worst airline in the world. The flight from London was delayed so that gave us little time for our connection in Madrid. When we got off the flight a women instructed us to take a coach to our connecting flight. The coach took us to the the wrong terminal about an hour away. Me and my elderly mother had to catch a train back to the correct terminal, go back through passport control and go back through baggage security. By the time we reached the gate our flight had gone. We were not able to run because my mother is elderly and fragile. We spoke to the Iberia help desk who told us that it was our fault for missing the plane. They said we were lying and that there were no delays despite us arriving an hour late. They put us on standby for the next flight. We waited for hours but the flight was full. We returned to customer service who were extremely unhelpful and I suspect racist. After a heated argument they refused to speak to me, give me any information about my bags or allow me to speak to the manager. They completely ignored me. I have never been so angry in my life. They basically told me and my mother to get lost, said we were lying about the delay and that we had plenty of time to reach the gate. Therefore they were not prepared to help at all. This is the worst airline ever. Please avoid at all costs.

I got bumped off my Iberia Flight to Nice in Madrid even though I was at the boarding gate before boarding started and had a boarding pass and had paid extra for choosing a seat. I and others were connecting from an Iberia flight from Coruna which was late, so they must have sold our seats to others. But the Nice flight was also late so we were at the gate before boarding started. There was 45 minutes wait at the Iberia service counter after we got bumped, so I bought another Iberia ticket on the next flight before they were all allocated. Iberia refused to refund me the second ticket when I eventually got to the service counter where they transferred me to that same flight on my original ticket. Not at any time did any Iberia staff apologise for selling my £350 seat to someone else. They react as if their customers are just a massive inconvenience to them. Who else could continue to trade while treating their customers with such contempt.
