Cosmos has entered the ski market for the first time with a programme to the little-known Spanish resort of Formigal.
Six hotels are included in the Cosmos programme, which will operate between January 16 and March 27.
In addition to selling flight-inclusive packages to the Pyrenean resort based on Monarch weekly charters, Cosmos is selling accommodation-only deals through its sister brand somewhere2stay.com.
Some seats on the Monarch flights, which will operate between Gatwick and Huesca in northern Spain, will be sold through flight-only arm Avro.
