UK tour operators and airlines have been forced to make last minute cancellations after the Moroccan government suspended all flights out of Britain.
Morocco made the snap decision due to the number of UK Covid cases which remains above 40,000 daily.
The number of hospitalisations is up 10% in the past week.
The suspension is for an indefinite period.
Trips to Morocco by fully vaccinated UK nationals are still allowed if via a third country.
Flights to Morocco from Germany and the Netherlands have also been suspended.
Airlines scrambled to cancel services with easyJet cancelling flights from the UK, Germany and Netherlands to Morocco until 30 November.
The airline is operating inbound flights to Manchester and Gatwick to bring back UK customers currently in Morocco.
"We are contacting all customers whose flights are cancelled with their options, which include a free of charge transfer, receiving a voucher or a refund," easyJet said.
Tour operator TUI is contacting impacted customers after suspending its Morocco programme
"We are contacting customers in departure date order to discuss their options, which include amending to another destination or a full refund."
TUI says it has about 2,000 customers in the country.
British Airways also cancelled Morocco flights.
Ryanair and Wizz Air also operate Morocco flights.
According to Morocco’s National Office of Airports the suspension will remain ‘until further notice.’
The Foreign Office has updated its advice on travel to Morocco.
"This will come as a blow to anyone who has booked a holiday to Morocco this half-term and demonstrates how international travel remains unpredictable," said Which? Travel editor Rory Boland.
