The budget carrier will offer eight leisure routes, starting from 17 June.
Destinations include Larnaca, Corfu, Heraklion, Faro, Alicante, Lanzarote, Palma and Tenerife.
It will also offer flights to Sharm-el-Sheikh in Egypt, starting in October.
Confirmation comes after the Welsh government lifted its ban on international leisure travel on Monday (17 May).
The country will operate a similar traffic light list to England and Scotland, and will also adopt the UK government’s initial 12-country green list.
