Do flight prices go up as the date gets closer?

Specifically, plane tickets usually don't get cheaper closer to the departure date. Instead, flights tend to be the most inexpensive when you book between four months and three weeks before your departure date.



In the vast majority of cases, flight prices do increase significantly as the departure date approaches. This is due to Yield Management algorithms used by airlines, which categorize seats into "buckets." The cheapest seats are sold early to price-sensitive leisure travelers. As these buckets fill up, only the more expensive fares remain, targeting last-minute business travelers who are less sensitive to cost and have no choice but to fly. Generally, the "sweet spot" for booking domestic flights is 1 to 3 months in advance, while international flights should be booked 2 to 8 months out. While the myth of the "last-minute deal" persists, it is a rarity in 2026; airlines now prefer to leave a seat empty rather than drastically drop the price and "devalue" their brand or encourage travelers to wait until the last second. The only time prices might drop close to the date is if a flight is significantly undersold, but with modern capacity-trimming strategies, most flights today operate near full capacity, making early booking the most reliable way to secure a lower fare.
