Overseas holiday bookings were up almost 8% for the three months to the end of May over the same time last year.
The average holiday cost was also up by more than 2% while turnover for the same period increased by over 16%, according to travel software specialist Multicom.
The upturn reflects growing confidence in the economy combined with a frustration of the worst spring weather for more than 50 years, the company said.
Managing director John Howell said: “These figures show a clear trend that bookings are up this year as people feel more confident about their financial security while also wanting to escape the poor British weather.
“The increase in spend per booking underlines the renew confidence holidaymakers have it would appear, while the increase in the cost per booking reflects the small rise in prices.
“The poor weather has also left many in need of a break from the uncertain summer ahead, choosing instead to make plans for a decent holiday where they can be assured of some sun and less rain.”
