Travel companies have slashed the cost of holidays abroad by up to 60 per cent after scorching temperatures and the World Cup tempted Britons to stay home.
Major firms are desperately cutting prices after failing to sell large numbers of package deals.
In some cases, family holidays that used to cost more than £1,160 are now on offer for less than £500.
Many companies are also running promotions such as free places for children.
Experts said the huge price reductions were ‘unprecedented’ for the peak season during the school holidays.
They said the heatwave has piled pressure on firms as fewer families attempted to find holidays abroad.
But insiders warned that if the weather turns cooler and everyone rushes to book a trip abroad at the same time, prices could jump back up.
Emma Grimster, of comparison site Travelsupermarket, said: ‘With the hot weather, as well as the World Cup earlier in the summer having caused a slow start to the holiday lates market, travel providers are now doing all they can to fill their planes and get people away.
‘There are some amazing deals to be had when booking last minute. For example, a three star, seven-night, self-catering break to Corfu departing on August 7 from Leeds is just £222 per person, based on a family of four.
For the peak season, this sort of price is just unprecedented and a clear indicator of how keen providers are to shift stock this summer.
However, to get these sorts of prices you will need to be flexible on your day of departure, with many of the best deals leaving mid-week.’
Earlier this month, Morgan Stanley leisure analyst Jamie Rollo told investors: ‘We spoke to a number of UK tour operators this week, and the consensus was that overseas holiday bookings have weakened in the last few weeks.
‘This was put down to a combination of the weather, following the longest heatwave since 1976 and June the driest month on record, and the World Cup.’
