In the latest contract between Île-de-France Mobilités and Keolis, operator of bus lines in Île-de-France, the operator is asked to provide a minimum transport offer on strike days.
When the offer is less than 50% of the normal offer, Île-de-France Mobilités may decide to reimburse users. Given the impact of the social movements in October and November on the bus network, Île-de-France Mobilités has decided to reimburse users, with a daily allowance of 2.80 euros (corresponding to 1/30 of the package)*.
Between 4 September and 20 October 2023, strike movements had a strong impact on the traffic of 7 bus lines in 9 municipalities in the Yvelines (Houilles, Carrières-sur-Seine, Chatou, Le Vésinet, Montesson, Croissy-sur-Seine, Bougival, La Celle-Saint-Cloud, Le Chesnay-Rocquencourt) with, on some days, a transport offer below the 50% contracted.
As a result, a right to compensation is open to all subscribers concerned and a compensation campaign is launched from December 6 to January 10, 2024 (inclusive).
A dedicated platform will allow you to submit your refund requests for the days impacted by the strike between September 4 and October 20, 2023.
Refund requests for the months of September and October 2023 must be made separately from each other. If you are eligible for both compensation operations, you must submit a claim for each month on the platform.
Seven bus lines are affected by the reimbursement in 9 municipalities of the Yvelines including: Houilles, Carrières-sur-Seine, Chatou, Le Vésinet, Montesson, Croissy-sur-Seine, Bougival, La Celle-Saint-Cloud, Le Chesnay-Rocquencourt.
The bus lines affected by the strike are: line A, line C, line D, line E, line F, line L and line T.
To access the refund, you must:
Please note that other transport tickets are not eligible for reimbursement.
Refunds are calculated according to the pass held by the user on the basis of a reimbursed amount of €2.80 per day of strike (corresponding to 1/30 of the pass) for an annual Navigo pass for all zones.
Packages with reduced rates and different zoning are reimbursed on this basis, in proportion to the reduction and the zoning applied to the public sale price.
Each user can receive one refund per month (September and October) and a maximum of two refunds, if they are eligible for compensation over the two months covered by the campaign.
In September 2023, 21 days were offered less than the 50% required by the contract, thus giving the subscribers concerned the right to a refund.
The compensation campaign for the month of September 2023 is open below until January 10 inclusive.

In October 2023, 20 days suffered a transport offer below the 50% required by the contract.
The compensation campaign for the month of October 2023 is open below until January 10 inclusive.

You must apply for a separate refund on the platform for the month of September and October.
*The price of compensation varies depending on the traveller's package
**Please note that each user is attached to a reference municipality according to their place of residence provided at the time of registration. If you have changed your address in the meantime, you will have to make a claim and provide proof of address during the period from September to October impacted by the strikes.
