Ok so I am planning on flying from Auckland, to Doha tomorrow and I plan on using the 777LR (which is considered to have one of the longest ranges)for the almost 18 hour flight. The LR in infinite flight can hold up to 19ish hours of fuel which I don’t find enough for the flight. The 300ER can hold up to a few more hours than the LR. The 300ER is supposed to have less range than the LR but can hold more fuel. What is a better aircraft for this route?
