Morocco has moved to ban all incoming flights from the UK due to soaring British Covid cases.
Direct flights from the UK will be banned from 11:59pm BST tonight for an indefinite period of time.
Morocco has also suspended flights from Germany and the Netherlands.
While travel from Britain will be banned from Morocco, the country is still allowing flights from France and Spain.
That means people travelling from Morocco will be able to return to the UK via other countries.
The UK Foreign Office said: "The Moroccan Government has announced the suspension for an unspecified period of direct flights between Morocco and the UK (and Germany and The Netherlands) with effect from midnight 20 October.
"Travellers affected by flight cancellations should contact their airline or tour operator for advice on alternative routes via third countries (eg France, Spain) where flights are operating as normal."
EasyJet, British Airways and Tui were among airlines that cancelled Morocco-bound flights.
EasyJet cancelled all flights to and from the Morocco due to depart on Thursday and will contact all customers with affected trips.
Tui said: "We are contacting customers in departure date order to discuss their options, which include amending to another destination or a full refund. We would like to thank our customers for their patience and understanding during this time."
The Moroccan national airline Royal Air Maroc assured passengers that they will allow unlimited ticket changes until December 15.
Royal Air Maroc said: "To support our passengers during this period, unlimited changes of ticket date and destination, free of charge until December 15, 2021 to the same or another destination are authorized."
The airline will also allow cash and voucher refunds.
The Morocco UK ban follows a suspension on all flights from Morocco to Russia on October 6.
