What’s the latest time to amend British Airways cash flights?

My daughter currently has covid but will return to Switzerland once she is out of self isolation. To get into Switzerland she needs a negative test (doesn’t have to be a PCR). Obviously there is a risk of getting a positive test on the morning of her flight. If not checked in when is the latest you can move your flight? Thanks in advance.
PS looks like anytime up until departure to me but want to be sure.

Not departure time but when check-in closes so usually 1 hr for long and 45 mins for short haul.
