You should fly to an airport in or near Milan, Italy, such as Milan Malpensa (MXP), Milan Linate (LIN), or Bergamo Orio al Serio (BGY), as these are the closest major airports serving the region. The best choice depends on your final destination within Lake Como, your airline preference, and the type of transport you'll use from the airport. You can then take a train, bus, or rental car to reach your desired town around the lake.
