The CAA is using a predicted boost in holiday bookings this “Blue Monday” to remind travellers to seek financial protection.
Research from Atol has found that 5.2 million Brits are expected to book a holiday this month.
Andy Cohen, head of Atol, said: “With the gloom surrounding Blue Monday, it’s no surprise that many UK holidaymakers are rushing to book summer travels to lift their spirits.
“If you are booking a package holiday today, look beyond the price and ensure your peace of mind by checking that the holiday is financially protected.”
Abta, meanwhile, has also released research predicting a boost.
Nearly a third (31%) of UK holidaymakers going on a winter break are planning to escape abroad to warmer destinations, according to new research by the association.
More people are seeking a winter sun getaway, up 3% on last year, in a move to avoid the winter blues and another prolonged cold snap, Abta added.
According to Abta members, the Canary Islands remain the number one destination for British tourists seeking sunnier weather this winter, with Tenerife, Lanzarote and Gran Canaria all ranking strongly for bookings.
At this time of year, temperatures in the region are often more than three times the average temperature at home, usually peaking between 17-20°C.
Cape Verde, Turkey and Egypt are also proving popular mid-haul choices, while Jamaica and Mexico are the pick of the long-haul destinations.
Victoria Bacon, Abta’s director of brand and business development, said: “As the British winter weather takes hold and the temperature drops, holidaymakers are seizing the opportunity to make an escape to warmer climes. This year is no exception, with even more people saying they’ll travel abroad for a fix of winter sun.”
