While I was at Gatwick until fairly recently, I lost count of the number of reports from concerned U2 Captains about A321s nearly tipping,
235 seats, standard procedure was to load the first 150 bags into the rear holds and any more than that in the front. Standard offload procedure was always to open both hold doors straight away, but unload rear first. Standard procedure was also to always have rear steps and to start offloading punters from the rear first. However, due to staff/equipment shortages this didn't always happen, resulting in the nose lifting, sometimes alarmingly so. In an ideal world, a full ramp team would be in situ for airrival of the aircraft - get the rear steps straight on, belt loader and baggage carts ready at the rear hold and get offloading the bags ASAP.
But it wasn't an ideal world and at the height of summer, the ramp team was still probably just finiishing pushing another aircraft out. By the time they arrived, exasperated dispatchers/cabin crew have already started kicking the punters out through the front jetbridge.
