I was at the airport to board, but I couldn't board because of the change in boarding rules to Brazil due to coronavirus. I bought the ticket on Saturday and the rules changed on Monday, the day I should have boarded. So I'm not requesting a cancellation because I didn't want to board, but because the law didn't allow me.
