From 27 March, Wizz Air will fly five times a week to Venice and from 29 March, twice weekly to Sicily’s capital Palermo. 

Wizz Air will also add two Black Sea destinations. From 13 June, it will launch five flights a week to Varna, and from 15 June, will fly four times a week to the port city of Burgas.

The airline is also increasing the frequency of its flights to Larnaca, Milan and Vienna from daily to twice daily on most days.

The carrier said it was expanding in order to fully use 15 daily slot pairs it acquired at Gatwick from Norwegian.

The UK government has also reintroduced the ‘use it or lose it’ rule this summer, which will compel airlines to use their allocations.

Marion Geoffroy, Wizz Air UK managing director, said: “We have continued to call for the full reinstatement of the original 80:20 slot usage rules and welcome the government’s recent decision to adjust the ratio to 70:30, so we can continue to take up new market opportunities.”
