Most “last-minute holidays” are actually booked a few weeks in advance rather than minutes. Launched in July 2014, an app called Flight Tonight is set to change this, offering travellers the cheapest round-trip flights departing in nearby airports in as little as two hours.

Showing its adventurous spirit, Heineken is letting travellers at New York's JFK airport change their flight to a more exotic destination at the push of a button. Heineken has already sent a man to Cyprus, booked a hotel and given him $2,000 for expenses.

Allocation-on-arrival holidays more often than not end in a nasty surprise – dingy rooms and out-of-town hotels. Discount airline Germanwings is now playing ‘travel roulette’ with destinations, so you could end up in Berlin or Milan. Terrifying maybe, but it’s appealing to spontaneous travellers.

Last-minute holidays account for around £26 billion annually, while one in three in the UK thinks they have a “spontaneous personality”. Can Flight Tonight, an app that offers the cheapest flights departing at nearby airports in just a few hours, cater to these risky travellers?
