Spain is the favourite country for foreign holidays this Easter, with the Canary and Balearic Islands the most popular destinations, according to Abta.
Tunisia, recovering from last year’s political upheaval during the Arab spring, and Cyprus have also sold well.
The association estimates 1.5 million British holidaymakers are set to travel overseas for the Easter weekend.
Paris, Dublin, Amsterdam, Rome and New York are the top five city break choices.
Domestic operators are reporting strong demand with many UK hotels and resorts fully booked, Abta said today.
Traditional UK holiday destinations such as Cornwall and Devon, the South Coast, Norfolk and Suffolk are all expected to be extremely busy.
Abta estimates that 370,000 will fly from Heathrow, 200,000 from Gatwick, 100,000 from Stansted and 65,000 from Luton.
More than 100,000 will be leave from Scottish airports, with 45,000 from Glasgow, 55,000 from Edinburgh.
A further 105,000 will leave from Manchester and 45,000 from Birmingham.
Other regional airports, ferry terminals and the channel tunnel will also be extremely busy over the weekend with hundreds of thousands leaving the country.
Eurostar is reporting 85,000 departing the UK with Paris, Amsterdam and Lyon the top destinations.
Abta chief executive Mark Tanzer said: “Easter is the traditional curtain raiser to the summer and I am delighted to see that hundreds of thousands of Brits are taking the opportunity to take a well-earned break both here in the UK and overseas.”
