Leoš Janáček Airport Ostrava — Mošnov, Czech Republic

Named after the celebrated Czech composer, OSR serves Ostrava, the country's third-largest city and the industrial heart of the Moravian-Silesian region, from a site at Mošnov roughly midway between Ostrava and Frýdek-Místek. Its long runway, originally built to Soviet-era military specifications, has occasionally made it a diversion option for flights unable to land at Prague, a role that speaks to capacity left underused relative to the infrastructure available. Passenger service remains modest compared with the Czech capital, leaning on charter flights, seasonal leisure routes, and a limited network of scheduled connections rather than a dense year-round schedule. Ostrava's economy, historically built on coal mining and steel production, has diversified in recent decades toward technology and services, a shift the airport has only partly kept pace with. The surrounding Moravian-Silesian landscape mixes industrial heritage with forest and hill country near the Polish and Slovak borders.
