ABTA is predicting about two million Britons will travel abroad this bank holiday weekend.
Friday and Saturday are predicted to be the busiest days, with one million people expected to fly from the southeast. Of those, 420,000 will leave from Heathrow, 260,000 from Gatwick, 160,000 from Stansted and 80,000 from Luton.
Regional airports are predicted to do well, with 160,000 passengers expected to pass through Manchester, 12,000 from Southampton, 70,000 from Birmingham and 50,000 from East Midlands. A further 140,000 Scots are expected to fly from Edinburgh, Glasgow and Aberdeen.
The Eurostar is expecting to handle about 85,000 passengers, while 400,000 Brits are expected to head out on ferries or the Eurotunnel.
The AA has predicted the roads will be quiet this bank holiday after a YouGov poll of 2,000 people revealed 56% of motorists will be staying at home for the weekend. People are keeping clear of the roads because of high petrol costs and the dreadful weather.
