With Tunisia off limits and Egypt and Turkey suffering from political problems, the travel industry is facing a capacity crunch.

There are now concerns that families, who haven’t yet booked holidays, are going to be priced out this summer.

David Hope, business group director at GfK Ascent, said that Portugal had already sold more 14-night summer holidays so far this year than during the whole of the trading period in 2015.

Other statistics also pointed to increased demand for so-called safer destinations.

Bookings to the end of January 2016 for this summer season compared with the same period last year are up 27% for Spain, 31% for Portugal and 28% for the Caribbean.

“What this is showing to me is that we either need to have a lot of additional capacity for these marketplaces or it’s going to reach a saturation point and if that happens, what will we be selling in the lates period?” he said.

Hope added: “Will the families that haven’t yet booked be priced out of some of these marketplaces?”
