In 2013, over 3 billion passengers took to the skies. As airlines aim to make flying as simple as taking the train, could everything people would normally associate with air travel – endless queues, bad food, cramped, uncomfortable seats – be about to change for the better?

From the lack of legroom, to irritating reclining seats – the misery of airline travel in economy-class is endless. As the amount of inflight personal space shrinks to cram more people onto planes, the biggest battle in the sky is where two seats meet. The Paperclip Armrest aims to provide a solution to the misery of ‘elbow wars’.

To find out how their passengers feel in-flight, British Airways is experimenting with an unsual idea, a "Happiness Blanket". In the same way a mood ring can indicate your mood, the blanket monitors brain waves using a headband and changes colours to reveal a passenger's mood.

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?
