Rough Wags : 400SLF @ 200lb with 100lbs bags each = 120,000lbs or 54,545 kg assuming no belly freight.
Freighter load just taken MXP to ORD: 92,000kg with 126,000kg of fuel.
Also bear in mind, less fuel required for the PAX bird as they're not as heavy.
On top of all that, we still managed a slightly reduced thrust takeoff just for the pleasure of seeing the end of the runway more clearly!(TIC)
