Please note that Flexi Season tickets have replaced our Peak Carnet tickets.
Off-Peak Carnet tickets offer a 10% discount on Standard Class travel, compared to the price of Off-Peak Day Return fares between the following stations and London:
Letchworth Garden City*
Welwyn Garden City*
Luton Airport Parkway**
St Albans City**
You can buy a Off-Peak Carnet book of either five or 10 single journey tickets.
Your Off-Peak Carnet tickets will need to be used within three months.
Off-Peak Carnet tickets are one-way, so you will need a separate book of Off-Peak Carnet tickets for your return journey.
You cannot combine your 10% discount with Railcard or GroupSave discounts.
The individual ticket journey price is based on half the relevant Off-Peak Day Return' fare discounted by 10%.
To use a ticket, you must fill in the travel date in black permanent ink before boarding the train.
