Some 110,000 passengers are stranded overseas and 300,000 future bookings have been cancelled after British airline Monarch collapsed into administration.
"We are sorry to inform you that, as of 2 October 2017, all future holidays and flights provided by these companies have been cancelled and are no longer operating," said a message on Monarch's website under the logo of Britain's Civil Aviation Authority (CAA).
"This is an unprecedented situation and because there are up to 110,000 passengers abroad, the UK government has asked the CAA to co-ordinate flights back to the UK for all Monarch customers currently overseas.
"These new flights will be at no extra cost to you." Some 300,000 future Monarch bookings were also cancelled, the Press Association reported.
