Thanks for your clarification. Was the NEXT day the earliest opportunity or was that the option you requested?
You only have the right to assistance as long as you have to wait for re-routing, under comparable transport conditions, to your final destination at the earliest opportunity or a return flight.
If say, they offered you on the non-stop Vueling/SWISS flight the same day, and you declined it... I'm afraid but it will be VERY difficult to recover the expenses.
