Researching and booking travel online has never been more popular - 55 per cent of internet users in the UK book their holidays directly online, according to Nielsen/NetRatings. But with so many sites on offer it can be difficult to see the wood for the trees.

That's why, here at Online Travel, we've divulged the contents of our favourites, quizzed our travel contacts, and surfed until we're square-eyed to bring you our favourite sites.

We recommend the sites on the basis of their content, design, ease of use, navigability and fulfilment, so they've jumped through all the right hoops to get onto this list. However, if you disagree with our choices, or can think of one we've omitted, let us know.

To make it easier, we've split them into ten categories, which you can search from this page.
