Iberia will add three additional flights to Buenos Aires a week from Madrid, taking its total weekly services to the Argentine capital to 17.
Three direct flights will operate on Mondays, Wednesdays and Saturdays, while two will commence on Tuesdays, Thursdays, Fridays and Sundays.
This represents a weekly capacity increase on the route of 16 percent, or 1,500 seats.
It is Iberia’s second South American expansion plan this year. Last month, the airline increased its number of flights to Lima to ten per week, raising seat capacity by almost 40 percent.
The carrier’s route to Buenos Aires commenced in 1946, with today’s flights operated on 254-seat Airbus 340-300s and 352-seat Airbus A340-600s.
Iberia operates flights to 38 European cities, ten African and Middle Eastern cities and 36 Spanish airports from Madrid, with some 1,000 flights taking off every day.
In December, the airline introduced a check-in service at London’s Paddington train station for passengers travelling to Heathrow. Similar facilities have also been installed in Dublin.
