Both first and second-class tickets include free WiFi, power sockets, and access to the food carriage. The biggest difference between first class and second class on SNCF trains: Quieter coaches. Roomier seats with headrests.

Traveling with SNCF (specifically on TGV INOUI) in 2026 offers two distinct experiences. 1st Class is designed for maximum comfort and business travelers, featuring wider, ergonomic seats that offer more legroom and a deeper recline. Each seat has its own dedicated power socket and individual reading light, whereas 2nd Class typically shares one socket between two passengers. In 1st Class, the seating is often in a 2+1 configuration (two seats on one side, one on the other), providing more "solo" options compared to the 2+2 layout in 2nd Class. While both classes have access to the "Bar" car for food and drinks, 1st Class passengers often enjoy a quieter atmosphere and access to SNCF Grand Voyageur lounges at major stations if they hold certain ticket types. For families, 2nd Class is often more practical as it houses the nursery areas and "Family Spaces" near the play zones. Overall, 1st Class is about personal space and productivity, while 2nd Class remains a high-quality, cost-effective way to traverse France at high speed.
