Aerolineas Argentinas has grounded 15 Boeing 737 aircraft in its domestic and regional fleet, after the aircraft were damaged by a severe hailstorm on 14 March at Buenos Aires Aeroparque airport.
The SkyTeam airline has cancelled multiple domestic flights until 25 March and temporarily halted all domestic fare sales.
The carrier cancelled 35 flights and re-scheduled 49 flights today.
No other airlines have reported similar damage to their aircraft.
An Aerolineas spokesman says the airline is assessing the aircraft damage with the help of Boeing, adding that some aircraft will require more complex repairs while others have been returned to service.
Aerolineas is deploying an Airbus A330 to transport passengers on high demand routes, he adds.
The airline hopes to have most of the aircraft back in operation before the Easter travel weekend.
