Solidarity rate

The solidarity rate is offered when you join the association and for most of our events.

To benefit from this rate, you can fill in a request form.

Request form

Only those with a solidarity fare code can purchase a seat at this rate.

The code is assigned after an eligibility test.

Rejected requests will be motivated and notified by e-mail. You will then be able to purchase a ticket at the regular rate (or be placed on a waiting list, if there are no more regular rate seats available).

For requests that are accepted when there are no more seats available at the solidarity or normal fare, you will have the possibility of being put on the waiting list for a seat at the solidarity fare and/or normal fare.


Applications are processed in order of receipt of the request form.
