As per the title, I was planning on using the RER to get to the airport to catch my flight last friday, however, due to a suspicious package at a station, all the trains were stopped where they were an did not move for a few hours. In that time it became clear I would miss my flight if I waited and so got an uber at the price of 90 euros, still however missing the flight. The airline said I would have to take the issue of compensation up with the train service as it is not their fault, is there anything I could do to get some compensation for this from the RER service?
Many thanks
