Iberia sold me a ticket to travel from Mexico City to Madrid, Spain Wednesday night, February 2. They canceled that flight because of the light load, made me travel Thursday the 3rd by day, costing my an extra $400 plus the call to Spain to change my itinerary. They didn't even bother to call me, just an email a few days ahead letting me know it was canceled. To top it off they wouldn't even compensate me with an upgrade in service. Bad service is one thing, but arrogance on top of bad service is inexcusable. Avoid this carrier if you can.
