That being said, I highly doubt those travelling in F on TATL are mostly leisure travellers. Yes, a few Yolo or points flyers are occasionally there, but the vast majority fo peole flying 'real' Long haul F are on someone else's dime, or deductible expense.

Either way... back to OP's question. No. No need to expand cabins. If demand goes up... raise prices.
