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.
