Monarch has secured £165m investment from its shareholder Greybull Capital easing fears about its future.
The injection of funds means the no-frills airline can renew its ATOL licence from the CAA for the next 12 months.
Last month, Monarch was forced to dismiss fears about its future and committed to operating flights as normal.
Greybull Capital is Monarch's majority shareholder after buying a majority stake in Monarch in 2014, with an investment of £125 million.
"As a result of this investment Monarch has successfully renewed its ATOL licences from the CAA for the next 12 months and funded future growth plans," it said.
"In October 2014, Monarch announced an order for 30 Boeing 737 MAX-8 aircraft, with options for a further 15 planes. The first of these aircraft is due to be delivered in 2018.
"The arrival of these state-of-the-art, fuel efficient aircraft in less than two years' will enable Monarch to continue to provide passengers with a best in class inflight experience and allow the company to enjoy significant operational cost savings."
Monarch employs about 2,800 people and is based at Luton Airport.
