Impressed with the range of A330-300. Actually thought at some point the Aircraft would be going for a swim in the Atlantic, but oh no , the calculations were correct with just over 65,000 remaining fuel , flying at 20,000ft at 300kts
20,000ft Cruise? Are you sure? If you cruised higher it would be much more fuel efficient and flight time effective. The usual flight time from LAS-LHR is about 9hrs35mins. Not sure if you did that on purpose or aren’t sure about cruise altitudes but it don’t matter I suppose…
