Choosing an Interrail Pass

Continuous vs Flexi Interrail Passes

Interrail Global Passes come in two shapes: flexi passes give you a set number of travel days to use within a longer window, while continuous passes are valid every single day for a fixed period. Choosing the wrong type is the most common way travellers overpay.

Key takeaways

  • Flexi = a number of travel days within a window (e.g. 5 within 1 month).
  • Continuous = unlimited travel every day for the period (e.g. 15 days).
  • Long city stays favour flexi; near-daily movement favours continuous.
  • Rule of thumb: if you travel on more than ~70% of your days, continuous tends to win.

How each pass is priced

A flexi pass charges for travel days, so its value comes from concentrating your train journeys into fewer days and resting in cities in between. A continuous pass charges for the whole period, so its value comes from moving almost every day.

A quick way to choose

Estimate how many of your trip days will include a train. Divide that by total trip length. If the result is high — you are moving most days — a continuous pass usually costs less per travel day. If it is low, a flexi pass with just enough travel days is cheaper.

  • 3 weeks, 7 travel days → flexi.
  • 15 days, train on 12 of them → continuous.

Frequently asked questions

Can I add travel days to a flexi pass later?

No. The travel-day count is fixed when you buy. If you expect to move more often, choose a higher flexi count or a continuous pass from the start.
