Flights & bookingThere's a real sweet spot for booking international flights, and it isn't the same number for every leg of a trip. Here's the actual timing that worked across 20 countries, and why the long-haul flights and the regional hops between them got booked on completely different schedules.

Roughly two to five months before departure is the window where long-haul international fares are typically at their most stable — early enough that peak-season routes haven't sold out of their cheaper fare classes, but not so early that the airline hasn't released its full schedule of pricing yet. Routes tied to a specific holiday or peak season (major national holidays, summer in Europe, cherry blossom season in Japan) are the exception — those are worth booking on the earlier end of that window, since the cheaper seats on popular dates sell out well before the flight itself does.
Peak-season and holiday travel rewards booking early, sometimes six months or more out, because it's less about the price dropping and more about the cheapest fare classes disappearing first. Off-season, flexible-date travel is the opposite case — prices on routes without a specific peak sometimes actually improve within a few weeks of departure as airlines try to fill remaining seats, though this is far less reliable than it used to be and isn't something to plan a whole trip around.
The handful of true long-haul legs on the trip (the flights connecting major regions rather than moving within one) got booked two to four months ahead, timed around when we'd firmed up which cities we were flying into and out of. The regional and budget-carrier hops between countries in the same region got booked much closer to departure, often just two to four weeks out, since prices on those routes moved far less and locking in a date months ahead would have meant giving up the flexibility to adjust the route as the trip actually unfolded.
Not reliably anymore — this was a real pattern years ago tied to how airlines released fare sales, but airline pricing algorithms have changed enough that day-of-week booking tricks make little consistent difference today. Booking window and flexibility matter far more than which day of the week you buy the ticket.
Sometimes, on off-season routes without strong demand, but it's unreliable enough that it isn't something to plan around. Popular routes and peak-season dates are far more likely to get more expensive as departure approaches, not cheaper, as the cheaper fare classes sell out first.
It's worth it for any flexible-date, non-peak route — a price tracker shows you the actual fare history for a route rather than a single snapshot, which makes it much easier to tell whether today's price is genuinely good or just average.
