Tips for cheaper tickets


Want to be sustainable but also save money on the journey?

  • Consider booking your journey in advance. For trains, this can sometimes be done 3-6 months in advance, dependent on carrier and rail company.
  • Booking websites may charge a booking fee. Consider booking on the original site to avoid this fee.
  • Consider travelling in the evening, as booking times are often cheaper.
  • Going away for the weekend? It is sometimes cheaper to book Saturday-Sunday-Monday rather than Friday-Saturday-Sunday.
  • Are you travelling in a group? NS International offers a group discount for groups of six people or more during off-peak hours.
