It's common to hear stories about someone who scored a super cheap flight at the last minute, and that feeds the idea that waiting until the last moment could be a strategy. But those stories are the exception, not the rule — and understanding why helps you avoid risky decisions.
The airfare market works in tiers of increasing prices. The cheapest seats are sold first, months before the trip, and the price rises as the date gets closer and demand for that specific flight increases or decreases.
The myth, in practice
The rare situations when last-minute flights get cheaper
- 01
Flights with very low demand
On routes or at times with little demand, an airline may lower the price to try to fill seats that would otherwise stay empty.
- 02
Operational schedule adjustments
In rare cases, changes to an airline's operations lead to one-off promotions on specific flights, unrelated to normal market behavior.
- 03
Routes with heavy competition between airlines
When two or three airlines compete intensely for the same route, prices can fluctuate more than on routes with little competition.
Risk
Why it's not worth counting on
Betting on a last-minute price drop is riskier than it seems. In the vast majority of cases, the opposite happens: the cheapest seats have already sold out, and only the highest fares remain, precisely because the airline knows that people who need to travel soon have less room to negotiate.
A real strategy
What to do instead of waiting for a price miracle
If your trip is urgent
- 1
Compare airlines as soon as you know you're traveling
The sooner you compare LATAM, GOL, and Azul, the better your chances of getting the lowest fare still available for your date.
- 2
Be flexible on time, not date
If the date can't change, the flight's time within that same day can still make a meaningful price difference.
- 3
Be wary of guaranteed low-price promises
No site can guarantee that a price will drop — what exists is real-time price comparison between available airlines.
- 4
Set a price ceiling and buy as soon as it appears
Waiting for an even lower price, with no set limit, is the most common way to end up paying more in the end.
Common questions
Frequently asked questions
Is there a time of day when last-minute flights get cheaper?
There's no guaranteed rule. What tends to happen is that flights with lower demand, like overnight departures, tend to have slightly lower prices, but this varies by route.
Can waiting until the day before the trip make the price drop?
In most cases, no. The natural trend is for the price to rise as the date approaches, because the cheapest seats have already been sold in earlier tiers.
Are apps that promise cheap last-minute flights reliable?
It's worth being skeptical of guaranteed-price promises. The safest approach is to compare the real fares offered by airlines at the moment you need to buy.
Why does someone occasionally find a genuinely cheap last-minute flight?
This happens in specific situations, like flights with very low demand or one-off adjustments to an airline's operations. These are rare cases, not a pattern you can plan around.
What should I do if I need to travel tomorrow and prices are high?
Compare every airline available for your route and time, and consider being flexible about the time within the same day — this usually helps more than waiting for the price to drop.
