This is very good advice which should be heeded.
When your plans change and you are not going to travel, NEVER cancel your ticket until the last practical moment before the ticket loses its value.
There could be a significant schedule change beforehand. There could be a flight cancellation on the day of departure. Both of those outcomes would make a non-refundable ticket refundable.
