It was quite some time back when I crewed a B747-400 minus one winglet. We were surprised there was no fuel penalty required with the applied MEL and don’t recall any additional fuel burn over the flight plan (AKL-SYD). Made us wonder what purpose they served. Not sure if current manuals are any different for the same situation.
