Executive chairman Philip Meeson confirmed the fresh cash injection, sourced from existing shareholders and new investors, in a note to the stock exchange on Friday (12 February).
It comes days after Jet2.com and Jet2holidays confirmed it was suspending all flights and holidays due to depart up to and on 14 April, and Iceland trips to 26 April.
Jet2.com and Jet2holidays had previously cancelled its entire winter schedule through to 25 March.
The latest announcement will see the launch of its new Bristol base, its 10th, delayed. Flights had been due to get under way from 1 April.
