Limited payload.
ELLX-PHNL 747-400F. Special charter flight (the 2 yachts for the Waterworld movie, Kevin Costner etc which were built in France) Aircraft was volumetrically full with about 25T payload. 7500NAM, reclearance (redispatch if you prefer), reserves were an interesting calculation. Max tanks fuel. Made a profit too.
Edit to say: I think it was BA that did EGLL-YSSY non-stop on a 400 pax to set a record. Unsure if they made any profit out of it.
