Jet2.com and Jet2holidays parent Dart Group has secured a £300 million commercial loan from the government’s Covid Corporate Financing Facility (CCFF).
The group said the cash would provide "standby liquidity" during the coronavirus crisis should it be required, and stressed it was currently unused.
It comes in addition to an existing £100 million credit facility Dart has already fully drawn down.
Executive chairman Philip Meeson said: "The group is grateful to both the Bank of England and HM Treasury for the provision of the CCFF.
"Together with the fully drawn revolving credit facility of £100 million, these two sources of additional liquidity will provide the group with headroom to deal with the present disruption and associated working capital requirements."
