Sicily is served by two main airports: Falcone-Borsellino Airport in
Palermo (West side of the island) and Fontana Rossa Airport in
Catania (East side of the island). Both airports are connected daily
to numerous Italian and international destinations.
A third airport which is the the civil airport of the province of
Trapani where Salemi is located is Sen. Vincenzo Florio in Trapani -
Birgi. From there you can reach daily Rome, Milan and the island of
Lampedusa (Pelagie).
So if you are planning a visit to Salemi, you might want to fly to
Palermo (PMO airport code) or Trapani (TPS airport code).
