Conclusion:

  • With Cathay’s lower fuel burn of 12,500 L/h, the B747-400 outperforms the A321XLR by over €41,000 in profit on the LPA → LAX route — even though the 321XLR is much more fuel-efficient.
  • The 747’s massive cabin and cargo capacity offset the fuel disadvantage, especially in a premium configuration.
  • The A321XLR could only compete if the route were shorter or the load factor and yield were much higher.
