Months of travel disruption expected at major US airport
US travel will also be affected by closures at San Francisco International Airport starting January 16.
The works to improve one of the runways will last five months and will mean that the airport has a reduced capacity.
As a result, around a third of international and domestic flights will experience delays of between 30 and 60 minutes, according to the airport.
The project is expected to be completed by July 1, however, “in advance of the Independence Day weekend and the peak summer travel season.”
