New Condor air frequency strengthens links to Europe
Growing demand from the European market has led to the German airline Condor to strengthen its commitment to our destination by adding a third weekly (Tuesdays) flight in its Frankfurt, Germany - San Jose, Costa Rica route. This frequency will be operated using a Boeing 767 aircraft with capacity for 259 passengers.
