Hi there, I recently booked standard economy on AF for an upcoming trip JFK-CDG-RAK via the KLM site as I had a large KLM ecredit I needed to burn from covid cancellations. Couple days later I realized I made a mistake with the booking and want to cancel, however KLM is no longer doing ecredits for nonrefundable flights.

I see I am able to change my flight from Standard to Flex... If I do so and then cancel, will I get a refund on the full ticket, or just the amount spent to change from Standard to Flex? Apologies if this is sort of an obvious question, but it seems like kind of a silly workaround for the fare rules! Thanks
