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.
