The Spanish carrier lost 19.2 bags for every 1,000 people who boarded its planes during the winter months, ending in March.
It was rated the worst performer among 26 participants in a survey carried out by the Association of European Airlines.
Air France came next, with 18.9 bags going astray per 1,000 passengers, followed by the Portuguese carrier, TAP with 17.3 bags and then Bmi, who "mishandled" 17.2 bags.
British Airways, which once used to languish at the bottom of the performance table continued to reap the benefits of Heathrow's Terminal 5 which, after a disastrous first few days, has been functioning well. It mishandled 15.6 bags per thousand passengers, a fraction of the number of bags that were going astray when the airline was at its worst.
Overall airlines mislaid 13 bags per 1.000 people they carried on board. In most cases the luggage is reunited with the rightful owner within 28 hours.
A spokesman for Iberia said: “The reason for our results in delayed luggage according to AEA is due to the heavy snowed in Madrid in the beginning of January that forced to close Barajas airport for one day and disruptions during two more days. Along with this, Iberia was suffering from December 2008 up to February 2009 a work to the rule strike by pilots, which led to cancellations and delays.
“For a network airline like Iberia this kind of things have a direct impact on delayed luggage.”
