There was some error in my maths on the first pass. Fuel Surcharge quoted is for a return journey. Originally I calculated Fuel Surcharge for round-trip against one-way fuel costs.<p>Analysis does assume flight are operating at 100% capacity, which is likely to be improbable.<p>Airlines can mix seating depending on 787-8. I got the figure 232 here: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Fuel_economy_in_aircraft" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Fuel_economy_in_aircraft</a>
