The carrier had planned a twice-weekly Antalya service from Gatwick commencing in May 2022, but will now offer this four times a week following promising early sales.
Flights will operate on Monday, Tuesday, Saturday and Sunday.
Freebird will also launch a twice-weekly service from Gatwick to Bodrum, also commencing in May, operating on Tuesday and Friday.
This will complement the existing Antalya services from Manchester, already operating twice weekly.
Carl Denton, UK sales representative, said: “Following our launch during the restrictions of the pandemic, we are now very encouraged to see consumer confidence return and bookings pick up.
