The service will launch next summer and will run twice a week on Mondays and Fridays, meaning customers can be in Djerba in around three hours and 15 minutes as part of their Tui holiday. Prices start from £659.
Tui UK and Ireland Managing Director Neil Swanson said: "Tunisia has been growing in popularity with our customers, and it is easy to see why. It offers sunshine, great beaches and really good value, which is exactly what many people are looking for when they are planning their next holiday."
Tui’s holiday programme includes hotels such as Tui Blue Palm Beach Palace, a beachfront adults-focused stay with a premium feel, and all inclusive Tui Magic Life Penelope Beach.
Swanson added: "Djerba has a lovely laid-back island feel, beautiful sandy beaches, warm temperatures for much of the year and plenty to explore if you want more than a week by the pool.
"By adding Tui Airways charter flights from Gatwick, we are making it even easier for customers to get there as part of their Tui holiday. It's a brilliant option for families, couples and groups who want somewhere sunny, great value and a little less expected.”
Tui holidays to Djerba are available to book now for next year.
