There are 5 Y seats on the 15:00 flight on the 2nd from LHR and some odd connections using BA and Air Berlin via DUS and STR. Nothing else available to non-OWE elites. No business seats available from LHR

ex LGW, nothing.

Worth pointing out this is the last weekend of the school summer holidays in the UK so flights will be busy and certainly no guarantee of availability becoming available. Italy is a super-popular destination and flights often sell out weeks in advance.
