Paying extra for Interrail seat reservations through the official portal is usually a waste of money because booking directly with train operators avoids added fees.
- Portal markup: Interrail charges a non-refundable €2.00 booking fee per passenger per train on online reservations.
- Free alternatives: Operators like České dráhy and UK train companies offer domestic seat reservations for €0.00.
- Cheaper carrier rates: Deutsche Bahn and ÖBB charge lower direct rates without adding third-party processing markups.
- Physical paper costs: The Interrail self-service portal adds a physical shipping fee of €9.00 per order when digital tickets are unavailable.
Are Interrail seat reservations worth paying extra for?
Interrail seat reservations are rarely worth paying extra for through the official self-service portal. While mandatory high-speed train reservations must be purchased to board, buying them through Interrail’s website adds unnecessary surcharge fees to your journey.
The main reason to avoid the central Interrail reservation system is the price markup. Eurail B.V. adds a non-refundable fee of €2.00 per passenger per train to every reservation made through its portal. If paper delivery is required because an electronic ticket cannot be issued, Interrail charges a physical shipping fee of €9.00 per order. Booking directly with the operating rail companies eliminates these middleman charges while giving you identical or better seat selection options.
How the direct carrier booking trick cuts your travel costs
The practical alternative to the Interrail portal is booking your passholder seat reservations directly through national rail operator websites. Most major European train operating companies allow passholders to purchase standalone seat assignments online for exact carrier fees or even for free.
Carriers in Central and Eastern Europe provide some of the best savings. České dráhy provides domestic train seat reservations for €0.00 when booked through its official e-shop. For international EuroCity and Railjet trains, České dráhy charges approximately €3.00 on its website without any added booking fee. In contrast, making that same reservation via Interrail adds the non-refundable €2.00 surcharge on top of the base cost.
In the United Kingdom, seat reservations on domestic long-distance routes operated by LNER and Avanti West Coast cost £0.00 / €0.00 via National Rail, allowing Interrail passholders to secure seats across Britain completely free of charge.
Comparing reservation costs: official portal vs direct rail carriers
Direct operator pricing consistently beats third-party portal fees. Deutsche Bahn charges €5.50 for a 2nd class long-distance seat reservation on ICE and IC trains when booked directly via its portal. For 1st class travel booked separately from a ticket, Deutsche Bahn charges €6.90. Deutsche Bahn also offers reduced child seat reservation fees of €4.90 in 2nd class and €5.90 in 1st class for children under 14. Buying these same seats through Interrail inflates each ticket price by €2.00 per person.
In Austria, ÖBB charges a seat reservation fee of €3.00 for domestic journeys when booked directly via the ÖBB app or ticket shop. Passholders holding an ÖBB Vorteilscard Comfort or ÖBB Reservierungsvorteil pay a discounted seat reservation fee of €1.50. Adding Interrail’s €2.00 fee to an ÖBB booking effectively increases the seat cost by up to 133%.

When mandatory reservations are unavoidable
While booking directly saves money on optional reservations, several European high-speed and international routes enforce mandatory passholder seat reservation fees regardless of where you purchase them.
In France, mandatory passholder seat reservation fees for domestic TGV INOUI trains cost €10.00 for limited-availability seats, rising to €20.00 for higher-tier seats once the limited quota sells out. Cross-border high-speed lines command even higher mandatory fees: TGV Lyria seat reservation fees between France and Switzerland cost €29.00 in 2nd class and €39.00 in 1st class, while international TGV seat reservations between Paris and Barcelona cost €35.00 according to SNCF and Interrail.com rates.
In Southern Europe, mandatory seat reservation fees on Frecciarossa high-speed domestic trains in Italy cost €13.00 in both 2nd class and 1st class. In Spain, mandatory seat reservation fees for AVE high-speed domestic trains cost €10.00 in 2nd class and €13.00 in 1st class. Flagship cross-Channel routes also come with hefty requirements: Eurostar passholder seat reservation fees between Paris and London cost €32.00 in 2nd class and €37.00 in 1st class.
Even on these mandatory routes, avoiding the official Interrail self-service tool saves you the additional €2.00 service charge per seat, keeping your total rail budget significantly lower over a multi-country itinerary.
Is relying on direct bookings always smooth?
The primary counter-argument for using the centralized Interrail portal is convenience. The official app pools multiple national rail systems into a single checkout interface, which can appeal to first-time travelers unfamiliar with regional rail sites.
However, paying convenience fees across a long trip adds up fast. A group of four taking five separate trains pays an extra €40.00 in non-refundable portal fees alone. Furthermore, direct carrier sites offer real-time carriage floor plans, letting you choose exact window or aisle seats that third-party portals frequently fail to present. Taking a few extra minutes to book directly on individual carrier apps keeps real money in your pocket while delivering a better onboard experience.
