More holidaymakers are booking early amidst fears the value of the pound will drop after Article 50 is triggered.
Since Brexit, it is estimated holidays in Europe cost an extra 15% following plunges in the value of the sterling.
Adam Walsh of holiday lettings company Interhome UK told The Guardian concerns over further devaluations had led to unusually high advance bookings. He said Interhome had seen large numbers of bookings from last August for this summer.
He said after Boxing Day, there was a rise of 50% on 2015’s figures in summer bookings.
“What seems to have happened is that people are hedging their bets early,” said Walsh.
“People are much more aware of the impact of sterling on the price of their holiday.”
