Monarch will launch year-round flights to Gran Canaria and Fuerteventura from a number of UK airports later this year.
The new Canary Islands routes will depart from Birmingham, London Gatwick, London Luton and Manchester.
From October 19th, one weekly flight will operate to Gran Canaria from Birmingham, while up to two a week will fly out of Gatwick and Manchester.
Two days later, Birmingham, Gatwick and Luton will service Fuerteventura with one flight a week, while two flights a week will operate from Manchester.
Liz Savage, Monarch flights and holidays managing director, said she was "delighted" to be launching the flights, which complement the existing routes to Tenerife and Lanzarote.
"We are seeing huge demand for our mid-haul destinations – in June we carried 59 percent more customers to Lanzarote and 16 percent more customers to Tenerife compared to June 2008 and the addition of Gran Canaria and Fuerteventura means even more people can take advantage of our low fares and award-winning onboard service to these popular sunshine islands this winter," she commented.
Elsewhere, Monarch began operating an additional charter flight to Antalya from London Gatwick on May 27th.
