How To Get Cheap Flights Last Minute: Tips To Save Big

Key takeaways 

• Airlines use dynamic, demand-based revenue management, so prices typically rise (not fall) as departure approaches. Last-minute tickets bought within a week of travel can cost up to 59% more than fares bought in the optimal window, according to CheapAir's annual airfare study.
• Letting the price lead—we call this "reverse your search" or "let the deal decide"—flips the usual approach. Instead of picking a destination and hunting for a fare, you let a deal-alert service like Going send you deals, which routinely surfaces fares 40–50% below normal per Going data, and then decide which destination is most appealing to you from the list of low fares. 
• Comparing nearby and alternate airports on either end of a trip can half the original fare in some cases, as smaller or secondary airports can carry lower landing fees, per Mighty Travels, as well as more airline competition that keeps fares low. 
• Skiplagging (hidden-city ticketing) can undercut a fare, but it comes with strings attached. If you’re going to do it, only do it with a carry-on, since checked bags route to the final ticketed destination, not your actual stop, and only if you're comfortable with the risk of an airline canceling the rest of your itinerary or flagging a loyalty account, according to NerdWallet's rundown of the risks.
• The best time to book a cheap flight is within the Goldilocks Window: 1–3 months ahead for domestic travel, 2–8 months ahead for international. If you’re traveling during a peak season, add a couple months to each of those windows. 
• Beyond higher prices, last-minute bookings carry other trade-offs, like restricted seat selection and a higher chance of connecting itineraries instead of nonstops. Some sources even say that mistake fares booked at the last minute have a higher chance of cancellation. 
• Flexible, deal-alert-driven booking works: Going members save an average of $200 on domestic economy tickets and $550 on international ones, with some mistake fares cutting the normal price by up to 90%.

How last-minute flight pricing works

There's a persistent belief that airlines slash prices on unsold seats right before a flight takes off, the same way a grocery store marks down bread at closing time. It's an appealing idea, but it doesn't reflect how modern airline pricing actually works. 

Airlines run sophisticated revenue management systems that divide every flight into "fare buckets,” or tiers of seats released at different price points. The cheapest buckets go on sale first, often months in advance, and as those seats sell, only pricier buckets remain. By the time your trip is a week or two away, the low-fare inventory is typically long gone, and what's left is priced for travelers who need to fly no matter the cost.

This is deliberate. Airlines want to sell "the right ticket to the right person at the right price," and a business traveler booking a flight tomorrow is, on average, far less price-sensitive than a vacationer booking three months out. Last-minute bookings signal urgency, so airlines reserve high-yield seats for exactly that moment, which is why fares often spike rather than drop as departure nears, a dynamic confirmed by industry analyses of airline pricing strategy and reporting from Aerospace Global News. 

That said, it isn't an ironclad rule: If a specific flight is running unusually empty and demand on that route is softer, airlines can, and occasionally do, drop prices at the last minute to fill seats. It's just far less common and far less predictable than most travelers assume, which is why chasing last-minute discounts as a primary strategy is risky.

The upshot is that "last minute" savings usually come not from waiting until the final days, but from working the system smarter, like by tracking prices, staying flexible, and using the right tools before the cheap fare buckets disappear entirely.

How to get cheap flights last minute: top strategies

Use flight price trackers

Before you can catch a good deal, you need visibility into what "good" actually looks like on your route. It helps to know that "price tracker" and "price alert" aren't always the same tool, even though the terms get used interchangeably. Some platforms do both while others only do one.

• Google Flights functions as both a tracker and an alert in one: Its price graph shows historical pricing for your route, so you can see whether today's fare is high, low, or typical, and its "Track prices" toggle also emails you when the fare moves, per Google Flights' support page.
• Skyscanner leans toward tracking and discovery first: Its whole-month calendar and "Everywhere" search let you see price trends across dates and destinations, and you can layer a route-specific price alert on top once you've settled on a search.
• Kayak builds in price-trend forecasting alongside its alerts, telling you whether to "buy now" or "wait" based on historical data. It also lets you manage every alert you've set from one dashboard, per Kayak.
• Going works differently from all three: Instead of tracking one route you specify, it curates and alerts you to deals from your home airport as its team finds them, so you're not doing the route-by-route tracking yourself.

Not every tool covers both jobs. A bare-bones fare calendar might only show historical trends without ever notifying you, while an alert service skips the trend data and just tells you when something changes. Using at least one of each—a tracker to learn what "cheap" actually looks like on your route, plus an alert to catch it the moment it appears—turns last-minute booking from a guessing game into an informed decision.

Set up airfare price alerts

If you are planning to go on a trip and have the time to wait for cheap prices, you can set fare alerts to track the price of a specific flight or route so that you’ll receive an email (or notification on an app) when the price of the flight changes. This way, you will be the first to know when to book those tickets. Additionally, it will let you analyze how prices change over time and detect patterns to score the best prices.

Let the deal decide

One of the most underused last-minute strategies is flipping the search around. Instead of picking a destination and hunting for a price, pick a price and let the destination come to you. Services like Going monitor deals from your home airport rather than one specific route, so instead of following a single flight, you follow an airport and get alerted whenever an exceptional fare pops up from it, whether it’s domestic or international. 

If your travel dates are flexible and you just want to go somewhere cheap, Going data shows that this "let the deal decide" approach routinely surfaces fares 40-50% below normal.

Subscribe to airline newsletters

Airlines love to drop special promotions or flash sales through their newsletters. By subscribing, you can get early access to these juicy deals; while airline promotions and flash sales aren't always the best place to score a deal if you have time on your side, they can be useful if you need to fly somewhere at the last minute.

Travel during off-peak seasons

Try to avoid peak travel times like holidays and summer vacations because that’s when prices usually skyrocket. Instead, go for off-peak vacations, such as late fall or early spring, when demand is lower and you’ll have a better shot at finding discounted last-minute flights. 

If you have flexible dates for traveling, you might want to move your vacations to off-peak seasons for the best deals. This happens because, during these months, airlines cannot guarantee they will sell all seats as in the high season, so they lower prices to increase demand.

Check nearby and alternate airports

A short drive can mean a much smaller bill. Both Skyscanner and Kayak let you search "nearby airports," so you can enter an entire metro area like New York to search JFK, LGA, and EWR simultaneously. 

Smaller, secondary airports often carry lower landing fees, which always get passed on to travelers. Comparing multiple airports on both ends of your trip can turn up savings of half the original fare in some cases, per Mighty Travels.

Search for one-way flights (works best for domestic flights)

For domestic trips, pricing one-way segments separately (rather than one roundtrip itinerary) can let you mix and match the cheapest airline in each direction. On low-cost carriers like Southwest, the penalty for going one-way is minimal, making this an easy way to build a custom, cheaper itinerary. Just be aware that some legacy carriers price one-ways at close to half the roundtrip fare, which erases the advantage, so always compare both ways before booking.

This strategy is generally most lucrative for domestic travel, but it can pay off on some international routes too, particularly on budget long-haul carriers like Norse Atlantic Airways and LEVEL, which price flights point-to-point rather than building a discount into the roundtrip. Norse Atlantic's one-way fares from JFK to London, for instance, have run as low as $114 versus roundtrip fares starting around $313, meaning two one-ways can come in well under the roundtrip price on some routes. 

Full-service international carriers, by contrast, typically price a one-way ticket at close to the roundtrip fare specifically to discourage this kind of mixing and matching, so always price both approaches before assuming a one-way search will save you money internationally.

Compare individual vs. group tickets

If you’re traveling as a group, compare the price of booking tickets individually versus all together, as booking tickets one by one (or in small groups, at least) could save you some money. In some cases, searching for individual tickets rather than for a larger group may not change the fare at all, but it is a good idea to take a look, just in case.

Use points and miles

Using your travel points or airline miles is a smart way to cut costs on last-minute flights. Airlines love to make points super confusing, but if you’ve got some frequent flyer miles ready to go, see if they can help lighten the financial load. You can often get great value from points on last-minute flights.

Book directly with the airline

While OTAs can be about 11% cheaper on average, booking directly gives you far more flexibility if plans change, an advantage for last-minute trips, which might be more likely to need adjusting. Airlines also tend to be more generous with rebooking and same-day changes for tickets sold on their own site versus an OTA-issued ticket, according to Dollar Flight Club and The Points Guy. It's worth pricing both, but weigh the OTA discount against the cost of reduced flexibility.

Fly standby or use a buddy pass

If you know someone who works for an airline, a buddy pass can get you on a flight for a fraction of the ticket price, though seats are never guaranteed. Standby veterans recommend taking the earliest flight of the day (more open seats, fewer weather delays), traveling with only a carry-on, and having a backup flight in mind in case yours fills up, according to SheBuysTravel's guide to buddy pass travel.

Catch error/mistake fares

Mistake fares are uncommon and unpredictable (but we do find them!). Users can subscribe to different tools in order to catch these rare deals, but you have to act fast as they can disappear in a flash! However, these are extremely rare, so do not wait for them to book your next flight.

Utilize airline rewards programs

Frequent flyer programs can offer last-minute redemption options, especially if you have elite status. Keep an eye on reward availability, and use your miles strategically for spontaneous traveling.

Book at least 21 days in advance 

As you get closer to your departure date, every day matters. Booking 21 days in advance is almost always cheaper than booking 14 days in advance, which is almost always cheaper than booking 7 days in advance. If you can nail down your plans a few days earlier, you’ll save some cash. 

When to book a last-minute flight for the cheapest price

If your trip truly is inside that final stretch, timing still matters, just within a narrower and more realistic window than "book the day before and hope." Due to advance purchase thresholds, prices spike 21, 14, and again 7 days before departure. So once you're within 21 days of departure, expect fares to climb steadily. For international trips, the ideal window is even further out, so a truly last-minute international booking (under three weeks out) is where you'll feel the steepest price jump.

Within that final short window, a few sub-patterns still hold some value. Midweek departures (i.e., Tuesday and Wednesday) and Saturdays tend to run cheaper than Friday or Sunday flights because leisure demand clusters around weekends. Flying midweek can save around $56 per ticket on average (climbing toward $100 during peak periods), according to travel timing research cited across multiple outlets. 

If you're using points, last-minute award seats, particularly in premium cabins, often open up in the final one to two weeks before departure as airlines try to fill capacity they couldn't sell for cash, per MileValue's analysis of last-minute award space. 

The honest answer to "when should I book last minute" is: as early within your available window as possible, ideally before the 21-day mark, and if you truly must book inside that window, stay flexible on airport, day of week, and cabin/redemption type to give yourself the best shot at a reasonable fare.

Top 10 best sites for last-minute flights (pros & cons)

As mentioned before, there are lots of tools that can help you find deals, track prices, and catch mistake fares. To make it easier for you to pick one, here are the top 10 platforms with their key features, pros, and cons.

Bereavement fares 

For those who find themselves in the unfortunate circumstances of having a family member pass away while being far away, it can be difficult to afford last-minute tickets, especially in unexpected situations. In the past, many airlines offered “bereavement fares” with special pricing for these cases, but very few still do it nowadays. 

Here are the details and requirements for bereavement fares on the airlines that offer them in North America. Mind you that each airline requires different documentation, so check out their policies before calling.

• Air Canada: Offers reduced fares for an imminent death or death in your immediate family. The fare applies within 10 days of travel (7 days for international trips), and refunds can be requested within 90 days if you traveled without a bereavement ticket.
• Alaska Airlines: Mileage Plan members get a 10% discount on the lowest available fare for a death in the immediate family. The fare applies within 7 days of travel and must be requested by phone.
• Delta Air Lines: SkyMiles members can access flexible tickets with no service fees for a death in the immediate family. The fare can only be booked by calling the airline and providing documentation.
• WestJet: Flexible tickets with no service fees are available for a death in the immediate family. You must call the airline, and tickets apply within 14 days of travel.

Airlines like American and United offer flexibility for trip changes or cancellations in the event of a death even if they don't have a specific bereavement fare policy. It's worth contacting airlines directly to ask about possible fee waivers, even if they don’t offer bereavement discounts.

Flight booking myths debunked

Let’s be real: Booking flights comes with a whole bunch of myths and misconceptions that travelers often fall for (we’ve all done it). These can totally mess with your plans and even cost you more in the long run. So, let’s bust three of the biggest myths about last-minute flight bookings and online pricing.

Booking at the last minute is always cheaper

We’ve said this before, but it’s worth repeating: No, it’s really not cheaper to book a flight at the last minute. Airlines used to see any empty seat at takeoff as lost cash, but now, with their fancy pricing algorithms, they’ve figured out they can make more money by cranking up prices and cashing in on business travelers who are desperate to pay full price for a last-minute or even same-day flight. 

In fact, due to advance purchase requirements, airlines often raise their prices 21, 14, and 7 days before the trip, so make sure to book your flights before these timeframes.

Clearing your cookies lowers prices

Another common belief is that airlines and travel websites use cookies to track your browsing behavior, raising prices if they see you repeatedly searching for the same flight. This has led to the popular advice of clearing your cookies or using incognito mode to get lower prices. But does it really work?

The myth likely stems from confusion about dynamic pricing, where airlines adjust prices in real-time based on factors like demand and booking pace. These changes can happen quickly, making it seem like prices are increasing due to your browsing activity.

Airlines base price changes on complex algorithms that include factors like seat availability, time until departure, and historical data—not on your cookie settings. While using a private browsing mode might give you peace of mind, it’s not going to actually lower the price of your flight.

There are specific times which are cheaper

For years, lots of travel blogs and “experts” have said that there are specific days, months, or hours when flights are cheaper. For instance, there is a common belief that you can find cheaper flights when searching late at night. But in fact, none of these are true.

What we can say is that prices are often cheaper during the Goldilocks Window, which is 2–8 months ahead of international flights and 1–3 months before domestic flights. This might be a little longer in the case of high-season flights, so keep that in mind. After this window, it might be a little more difficult to find cheaper fares, as airlines tend to increase prices last minute, but using flight alerts could help you keep prices down, especially if you have some flexibility.

Finding cheap flights can be a time-consuming and often frustrating process, especially when you’re hunting for last-minute deals. This is where a flight subscription service like Going comes in, offering a hassle-free way to find the best fares without the endless searching and uncertainty.

Frequently asked questions

Should you book last-minute flights?

Booking last-minute flights can be a gamble. While you might occasionally find great deals, it’s generally not the most reliable way to score cheap airfare, as airlines often raise prices as the departure date approaches. Using flight subscription services like Going can help you discover rare last-minute deals in case you cannot pick other dates or destinations.

Is it cheaper to book flights in advance or last minute?

In the past, booking flights last minute could get you some savings, as empty seats represented lost money for airlines. However, pricing algorithms allow airlines to keep their prices up, or even increase them, right before the trip. For this reason, it is much more advisable to book your international flights 2–8 months in advance and domestic flights 1–3 months in advance.

Can you get cheaper flights closer to the date?

Typically, no. As your departure date approaches, flight prices tend to increase. Booking flights at least 21 days in advance is often cheaper than waiting until the last minute. For example, flights booked 21 days out are usually more affordable than those booked just 14 days out, and much cheaper than booking 7 days in advance. If you can confirm your plans a few days earlier, you’ll likely save money on your ticket.

Is it cheaper to book trips last-minute?

Not usually. Last-minute trips are often more expensive because airlines and hotels know travelers booking close to departure are less flexible. However, you can sometimes find deals on unsold seats or packages if demand is low.

What are the risks of booking a flight last minute?

Beyond higher prices, last-minute bookings mean less seat selection, a higher chance of connecting itineraries instead of nonstops, and less availability in your preferred cabin. Also, some sources say that mistake fares booked at the last minute have a higher chance of cancellation. Booking directly with the airline helps mitigate some of this risk, since you'll typically have an easier time getting rebooked if something changes.

Which airlines have the best last-minute deals?

There's no single airline that consistently wins on last-minute pricing, since it depends heavily on the specific route and how full that flight is running. Low-cost carriers like Southwest tend to have smaller one-way pricing penalties, which can help if you're piecing together a one-way itinerary, per Thrifty Traveler's fare analysis, while legacy carriers like American and Delta sometimes release strong last-minute business-class award space through their own loyalty programs, according to MileValue.

How late can you book a flight before departure?

Most airlines allow booking right up until check-in closes, often as little as 30-60 minutes before departure for domestic flights, though prices in that final window are almost always at their highest. If you book directly with a US airline at least seven days before departure, you're also covered by the DOT's 24-hour rule, which lets you cancel for a full refund within 24 hours of purchase, a useful safety net if you're booking in a hurry and want a chance to double-check your plans.
