Overview
- SNCF opened its online ticketing for the end‑of‑year period on Wednesday, September 30, 2026, making TGV Inoui, Ouigo, Intercités and selected international services available to buy.
- TGV Inoui and Intercités are bookable for travel between December 13 and January 6, Ouigo fares extend to July 2, 2027, and some international journeys are on sale through late March 2027.
- The operator said it added targeted capacity, including 36,000 extra seats per week to Strasbourg and Colmar from November 26 to December 23, more than 300,000 seats to Alpine resorts over the holidays and six extra weekend TGVs to Bourg‑Saint‑Maurice from November 27, plus additional Paris–Germany frequencies.
- Passengers are warned that SNCF uses yield‑management pricing that raises fares as trains fill, so buying at opening can save up to about 30%; ticket flexibility also varies by product with standard TGV Inoui fares exchangeable until seven days before departure and Ouigo changes allowed for a fixed €19 fee.
- Past openings have sold out fast—about 1.6 million seats went in under 24 hours last year—so travelers should compare rival operators on shared routes, check regional TER windows, and use discounts such as the historic 'billet congé annuel' for potential savings.
