American Airlines made this announcement:

Due to the reduction in demand, American Airlines is suspending operations to and from Milan, Italy, and New York (JFK) and Miami (MIA). Flights to Milan are scheduled to resume April 25.

Our teams are contacting affected customers directly to accommodate their needs. American continues to review the airline’s flight schedule to ensure that customers’ needs are accommodated and will make additional refinements as necessary.

American serves Malpensa Airport (MXP) from JFK and MIA. There is one flight to and from each city per day.
