Eligible season ticket holders affected by the May timetable disruption have until 30 November to reclaim compensation.
Embattled operator Govia Thameslink Railway (GTR) has opened the second phase of its compensation scheme for passengers who were hit with cancellations and delays arising from the timetable overhaul in May.
GTR, which operates Thameslink, Great Northern, Southern and Gatwick Express services, has already contacted 63,000 passengers by email to invite them to claim compensation. Now it has asked other season ticket holders who it has not contacted to go online to see if they qualify to make a claim.
To be eligible you must have held a season ticket for travel from most of the affected stations from between 20 May and 28 July. The money you receive back will be based on the equivalent cost of one to four weeks' travel.
Meanwhile, non-season ticket holders such as part-time workers could be eligible to claim compensation from 30 November. GTR has advised customers to keep any tickets, receipts, contactless journey histories or other proof of travel.
Passengers who have made a minimum of three days’ return travel in any week will qualify for a refund.
GTR chief executive Patrick Verwer said: “We are sorry for the disruption caused by the May timetable change and would urge affected season ticket holders who haven’t already heard from us to claim through our compensation website.
“We have turned a corner in terms of performance and services are now more punctual.”
