Ryanair has stepped in with “rescue fares” after Wizz Air cut nine winter sun route from Cardiff airport.
Only one of the Ryanair routes operates from the Welsh airport, with the rest from Bristol.
The Irish no-frills carrier is offering fares starting at £39.99 to passengers who had been booked on the Cardiff flights being cancelled by Wizz Air from September 19.
Wizz Air is dropping services to Alicante, Corfu, Heraklion, Faro, Larnaca, Lanzarote, Palma, Sharm el-Sheikh and Tenerife and will only operate to Milan and Bucharest from Cardiff over the winter from October 30.
Ryanair is offering alternative flights to Faro from Cardiff and Bristol and from Bristol to Alicante, Malaga, Palma and Tenerife for travel until the end of October but the special fares must be booked by midnight on Monday (August 15).
Ryanair marketing and digital director Dara Brady said: “While Wizz Air is cutting flights to top European destinations such as Faro and Tenerife, Ryanair continues to operate a full schedule with over 3,000 daily flights and we are ready to accommodate the holiday needs of families flying from Cardiff who have been affected by these Wizz Air disruptions.”
