So it's good news that Interrail Global Passes are going on sale when booked through National Rail.
From 6am tomorrow, Tuesday 11 March, Interrail by National Rail will be offering 15 per cent off Interrail Global Passes and many One Country Passes (excluding Switzerland). The offer ends at midnight on 1 April (don't worry, it's not an April Fool).
Global Passes are flexible – you can purchase passes that allow between four days of travel in one month and continuous travel for one, two or three months.
A One Country Pass offers travel on the railways of 30 different countries for up to eight days within one month.
Sale prices start at £205 for an adult Global Pass, and all purchased passes must be activated up to 11 months from the date of purchase.
