Monarch customers in the United Kingdom and yet to travel: do not go to the airport as there will be no more Monarch flights.
The British Civil Aviation Authority (CAA) president, Deidre Hutton, said it had chartered aircraft for the next two weeks to get all those affected back home. The regulator said everyone due to fly in the next fortnight would be brought back to the United Kingdom at no cost to them and that there was no need for them to cut short their stay.
Monarch has ceased trading with immediate effect, leaving 110,000 customers stranded overseas and around 300,000 future bookings cancelled.
The aviation authority says it will organize "flights back to the United Kingdom for all Monarch customers now overseas".

This is the UK's largest ever airline to enter administration.
Monarch Airlines went into administration Monday, cancelling flights and holidays as Britain's government worked to bring home as many as 110 000 passengers, according to messages posted on the company's Twitter feed and website.
Gatwick Airport - one of the United Kingdom airports Monarch had flown out of - confirmed the news early this morning and issued advice to passengers.
"We are today mounting the biggest civilian repatriation exercise this country has seen in peacetime", said British Transport Secretary Chris Grayling. Due to the short notice and large scale of the operation to get stranded passengers back to the United Kingdom, the CAA is advising passengers to get to the airport at least three hours before their scheduled replacement flight.
Here is all you need to know about Monarch's demise.
The collapse of the airline was a result of higher competition and lower prices in Spain and Portugal due to security concerns in other holiday destinations, Chief Executive Andrew Swaffield told BBC radio in an interview.More news: Negotiations with 'little rocket man' waste of time
