The failure of the refueling system at Lisbon airport last Wednesday had knock-on effects at 39 airports and left 50,000 thousands passengers stranded.
The hardest hit were Madrid-Barajas, Brussels, Amsterdam Schiphol, Paris-Orly and Barcelona-El Prat after the Lisbon fuel system failed. This may be the responsibility of Grupo Operacional de Combustíveis run by Petrogal - a full inquiry is underway.
