We have got G-VGAL operating out of LHR at the moment, which is an LGW based a/c. They do not have the beauty therapist service or bar onboard, as they are config'd for more economy pax, as the routes out of LGW are more 'Holiday' destinations.
Shamrock is correct that they do have the Alitalia seats in Upper and currently no plans to install the 'New' upper seat on the LGW a/c due to costs etc., and I would ask for a seat as close to front as poss, as last row in upper is in front of the bulkhead between upper and economy, and the first row of economy has the bassinet position which = screaming baby!!.
Enjoy the flight
