With 75.3 million iPhones sold in 2010 alone, the age of the Smartphone is well and truly upon us. One of the principle innovations associated with the rise of the Smartphone is, of course, the ‘App’.

There are already a plethora of apps catering to every conceivable aspect of modern living and the development of these often whimsical, frequently rather handy and sometimes near indispensable little applications is set to accelerate in 2011. One area that is sure to see a surge in smartphone apps this year is the travel sector.

Apps seem set to impact the travel sector in a big way and DialAFlight, one of the biggest providers of cheap flights worldwide, have lead the way by launching an iPhone application that gives some indication of how Smartphone technology can improve the traveller’s experience.

The free app, which provides users with a complete travel itinerary, updated flight status, a ‘find my hotel’ function and a guide to the best flight prices, was amongst the first in the travel sector to hit the market. This makes finding cheap flights to Bangkok, New Zealand, Cape Town and other exotic locations a dream to organise.

The smart phone allows users to have more control over their holiday experience. With utilities such as mapping, currency converters and travel updates, it promises to take the stress out of travel. No more back seat drivers or bad navigators, just enter your hotel details and let GPS take the reins.

Finding cheap flight details on the go is now so easy, there’s no excuse not to travel cheap. Confidence in the smart phone is steadily increasing and the ease with which flight deals can be checked, hotels booked, travel itinerary and travel guides downloaded is transforming the way we travel.
