It avoids the crazy UK quarantine (if it happens and if it continues): hopefully making my arrival in Italy from a Schengen country.
Given the date, the BLQ-LON flight may yet be cancelled, but assuming it is not and you wish to return, then you will need to take some action to preserve the return. You can claim the involuntary cancellation refund for LHR-BLQ, but the ticket won't normally work for the return without some agent action to confirm it.
