I have a flight that I need to cancel because of the COVID-19. It is a R class ticket from OSL to SIN and back and the flight is in 5 days. Do I cancel first and then request a refund or travel voucher or do I just send in the request form? It says that it may take 5 business days to process the request in which case it doesn't meet the 3 days in advance criteria. I have been trying to call but to no avail. Anybody in the know?
