We arrived in Malaga Spain on a Iberia Air flight from Heathrow Business class, One suitcase arrived one missing, we completed the necessary forms and read the fine print on the lost luggage reimbursement form, three full days before you get anything. We went back to the airport the 2nd day and again kept our cool about where and when the lost luggage would arrive. They again put out a tracer on it. That day we were on to Granada we gave Iberia the the hotel where we were staying. Then I read the stories of the lost luggage warehouses that Iberia has.
Well we were lucky, on the 3rd day the suitcase arrived. Now my wife had her items and it made the vacation much more enjoyable. The moral is pack at least 2 days of personal items in your carry on bag.

Save travels,
