Prem's fares are heavily discounted fares with very restricted availability. They can usually only be booked up to 14 days in advance (although some Prem's fares can be booked up to 7 days in advance). Because of the restricted availability, seats/couchettes at Prem's rates can sell out very quickly, especially on peak departure times and dates.l

What kinds of discount do Prem's fares offer?
Prem's fares are not calculated as a percentage of full fares, unlike Discovery fares.

There are generally 4 price levels:
Level Zero or Lead-in fare which is a fixed price regardless of the route but it is different depending on whether the passenger travels in a standard class seat, a first class seat, a 4-berth couchette etc.


Level Zero prices start at:
Standard class on a TGV is £19 and Corail is £11.50
First class on a TGV is £33.50 and Corail is £19.00
Standard class couchettes (6-berth couchettes) on a overnight French domestic train is £26
First class couchettes (4-berth couchettes) on an overnight French domestic train is £44.50

Levels One, Two, and Three are more expensive but with better availability, as follows:

Price  Level  Availability:
Lead-in            Extremely restricted
Intermediate 1  Very restricted
Intermediate 2  Quite restricted
Intermediate 3  Restricted

The prices for Levels One, Two and Three are different depending on the route.

Where does the name Prem's come from?Prem's is an abbreviation of the French word "Premier" (meaning "first"). When children play a game and have to designate who starts first, the first one to start is the one who says "prem's" first.
SNCF have used this word, as Prem's are cheap fares which are available to those who book their journey well in advance.in other words to those who book first.

On which routes are Prem's fare valid?
Prem's fares are valid on selected French domestic routes (TGV, Corail (Day and Overnight), TIR) and on some international routes including Artesia and Paris to Luxembourg.
