There's a tradeoff between passengers and fuel - the quoted range with a standard passenger load is not the maximum range. E.g. the 777-8 has a range of 16,090 km (8690 nmi) with 365 passengers, but the business jet variant (BBJ 777-8) has a range of 21,570 km (11,645 nmi). We are so close to airliners that can fly non-stop between any two major cities on Earth. Not sure I'd want to do 20+ hour flights, but amazing that we will be able to soon.
