Foreign holidays have been banned for at least a month under new national lockdown rules announced by the prime minister.
The restrictions in England prohibit day trips and holidays abroad, as those are not among the specific exemptions for leaving home such as attending school or going to the supermarket.
Boris Johnson announced the measures as part of new restrictions that will start on Thursday and then be reviewed on 2 December, when they could be extended.
Current and future holidays have now been thrown into chaos for many.
If you are currently abroad airlines are responsible under consumer law to bring you home, but flight schedules will be slashed in response to the drop in demand, meaning many people will be forced to change their travel dates.
Travellers are not required to return early.
If your flight is still going ahead and nothing has changed in your destination, you are not automatically entitled to a refund.
But many aircraft are likely to be grounded from Thursday due to the new restrictions, meaning people with existing bookings will be due a refund.
UK consumers are protected under European laws which state that they should receive full cash refunds within seven days for cancelled flights and 14 days for package holidays that do not take place.
But since the coronavirus outbreak many people have faced difficulties obtaining payouts from airlines and holiday firms.
That situation is likely to continue over the coming weeks.
The Prime Minister did not mention travel corridors in his Saturday press conference, meaning people arriving from some areas are likely to continue being exempt from quarantine.
But the lockdown means the number of travellers will be diminished anyway.
