Got back last week from a trip to St Maarten with AF where my outbound flight was delayed leaving LHR due to snow in Paris and I missed my connection.
AF rebooked me on the next flight and provided a hotel room and meal vouchers without being asked. However the TV news that night showed the scene at Schiphol where KLM were making their passengers sleep on the floor.
Food was take it or leave it in economy, this may only be the case on leisure routes with no choice and no pre ordered special meals had been loaded.
Legroom on the A340 was certainly better than on Virgin.
