This is a 3,999 miles journey, about 8h 16m in the air on a nonstop, which puts it firmly in long-haul territory: baggage allowances, seat selection fees, and stopover options change the real cost of the ticket as much as the base fare does.
For long-haul travel, mid-January to March and the shoulder months of October and November usually bring the lowest fares; June through August and the December holidays cost the most.
Tuesday, Wednesday, and Saturday departures are usually the cheapest days on long-haul routes; Friday and Sunday are the most expensive. Early-morning and late-evening flights are often priced below the midday departures.
For international travel, booking two to five months ahead usually gets the best fares; inside three weeks, prices rise sharply. Peak-season travel in summer and over the December holidays should be booked as early as possible.
