What happens to the care obligation (food, drink, accommodation) when the passenger decides to travel at a later date, at his convenience?

Following the passenger’s choice of rerouting at a later date, at its convenience, the carrier no longer has any obligation with respect to the right of care.

However, if a passenger decides to request re-routing, under comparable transport conditions, in order to reach its final destination as soon as possible, the obligation of the operating air carrier to take care until the departure of rerouting applies.
