Nearly 14 million drivers are expected to hit the road in the final weekend before Christmas, marking a new record, according to automotive group RAC.
Disruption to some train services is also expected due to engineering works, adding to road congestion, while windy weather has led to the cancellation of some ferry services and flights.
So how can you make your journey – whether by road, train, plane or ferry – as smooth as possible?
Shift travel times on the roads
The RAC says that overall the impact of the Christmas getaway will mean many roads “will be busier” than on an average weekend.
The five hours between 1pm and 6pm on Saturday were expected to be the busiest period on the roads – but many more journeys will be made given Christmas falls on a weekday.
The AA advises people to come prepared with plenty of fuel, charge their phones and check tires and lights.
He also suggests packing food and warm clothes in case you get stuck in a traffic jam.
“Check traffic reports before you leave and try to travel when it's quieter if you can, or consider taking a different route to avoid traffic jams,” says the AA's Chris Wood.
Travel expert Julian Bray advises if you're traveling by road, “go earlier and come back later” as rail works taking place over the festive period will also increase traffic.
Check railway engineering works
Network Rail advises passengers to check their trip before traveling.

Allowing plenty of time to get to your departure airport is a good idea, as are rules for checking bags, as some airlines have recently changed their policies.
It also clarifies that customers must always reconfirm their return trip before leaving.
Which? says passengers will also be entitled to assistance from the airline, including food and beverages, if their flight is delayed by more than two hours.
“For short-haul flights, the compensation threshold kicks in after a three-hour delay – but is only payable if the delay is considered to be within the airline's control, meaning you don't “You won't be eligible if your plane is held up by a snowstorm or security incident,” says Boland.
In the event of a cancellation, you should also have the choice of a refund or rebooking on the next available flight.
