Britain has several transportation options for travel within and to the country. British Airways is the national airline but many popular low-cost carriers like EasyJet and Ryanair also fly to Britain. The British rail network spans over 16,500 km and train travel is a good option as prices are reasonable. Bus travel is also good in Britain with fast and comfortable services provided by companies like Eurolines and National Express. You can take the Channel Tunnel by train between Paris and Brussels, putting your car on board, or travel by ferry from Spain, France or Ireland.
