Canada, the Caribbean, Mexico and Thailand are expected to gain as British holidaymakers act to avoid the US since president Donald Trump came to power.

Almost a third of Britons have been put off holidaying in the US in a so-called ‘Trump slump’.

If they stay away in such numbers, the cost to the US economy could exceed $1.5 billion.

Figures from Cheapflights show a 13% fall in searches for flight from the UK to the US since Trump entered the White House and searches are currently 10% behind this time last year.

Company managing director Andrew Shelton said: “A month into the new presidency and fears of the so-called ‘Trump slump’ seem to taking substance.

“Our poll asked directly if people were more or less likely to travel to the US since Trump took the oath of office. Their responses show that a significant number of Brits have been spooked by what they see happening over the pond, and are beginning to vote with their clicks as they explore alternative options for travel in 2017.

“At the height of the travel ban furore earlier this month, searches dropped almost 20% week-on-week against an overall increase of demand to our sites and apps of 19% compared to this time last year.”

He added: “With UK travellers contributing nearly $5 billion a year to the US economy, tourism chiefs in the country should take note of what could be a substantial reduction in support for a major industry there.

“America’s loss is another country’s gain, however, as our search stats and research show.

“A range of alternative destinations appear to be mopping up the demand that the US is potentially leaking, with Canada topping the list of holiday hot spots that have become more appealing to British travellers than the US since Trump entered the White House, followed by The Caribbean, Mexico and Thailand.”

Cheapflights’ statistics show a 32% fall in flight searches from Newcastle to the US since Trump took office. Searches from Aberdeen, Belfast, Glasgow and Birmingham are down 27%, 26%, 22% and 22% respectively.

Londoners are the least deterred with demand for US travel from the capital down by just 6%.

Shelton said: “The global uncertainty does spell good news for holidaymakers’ bank balances.

“Analysis of average lowest fares to the US and a selection of alternative destinations in 2017 versus 2016 points to some serious savings.

“Fares from the UK to the US and Canada are down by 18% year-on-year. For Thailand, fares are 27% lower, for Mexico they are 25% cheaper and for the Caribbean, 21%. So, there are flight bargains to be had, whether holidaymakers decide to front or dump Trump.”
