LOT Polish Airlines will launch new services from Warsaw to Bangkok and Seoul next year.
The carrier plans to start both long-haul routes in autumn 2016.
Further details are not currently available, although it is likely LOT will fly Dreamliners to both destinations.
The news comes just days after LOT revealed it will begin a year-round operation to Tokyo Narita in January (see news, June 19).
The airline has also announced it will commence three new Europe services to Venice; Cluj – Napoca in Romania (from January); and Ljubljana in Slovenia (from March).
