We didn't call anything in or enter anything into the weight and balance, not every plane was serviced, and it never kept flights from receiving their manifests. As I recall, there was a standard placeholder figure that was used, similar to how they use an "typical" passenger and baggage weight rather than weighing everyone.
My experience is over 10 years ago though, so maybe things have changed?
Perhaps. Please view attached document from aeroflot/airbus. This it the same vacuum system on the UA 320 series. If there are any recirc systems left, it may be perhaps a late model 757. All 737 NG's (600/700/800/900) have vacuum systems. Classic 737's (100/200/300/400/500) had re-circulation.
So, no blue juice on the current fleet.
As far as the final weights manifest, that took place with the SABER changeover a few years back. If a lav/water service was not completed (or entered complete), final wights will not push to the acars.
