Unsold airline seats sound like a great opportunity for travelers looking to save some money. Airlines do sometimes fly with empty rows, which is lost revenue for them.
Carriers sometimes cut prices on seats that are still empty, but last-minute bargains are the exception rather than the rule: Google’s analysis of U.S. fares found that domestic prices have usually been lowest 21 to 60 days before departure. This guide explains how to use a travel app to track price drops on your route, whenever they happen.
Where to find unsold airline tickets?
Finding a good fare is rarely as simple as checking one airline’s website. Comparison tools show prices from many airlines and booking sites side by side.
One option is KAYAK. The app is available for Android, iOS and on its official website. It compares fares from many airlines and booking sites, so you can see when the price on your route drops.
Modern travel apps can track many routes at once and flag price drops as soon as they appear. That monitoring is a useful tool for budget travelers.
Don’t count on a last-minute sweet spot, though. Last-minute fares are often higher than fares booked weeks ahead, so if your dates are flexible, set alerts early and book when the price looks good.
Step-by-step: how to search for unsold seats on sale through KAYAK
KAYAK is a popular choice for comparing fares. It works like a search engine, pulling prices from hundreds of travel sites. Check out these steps to track the fares on your route.
- Install and open. Download the KAYAK app from your respective store. Once open, you can start searching immediately without even creating an account.
- Use the explore tool. Tap the ‘Explore’ button at the bottom. This allows you to set a budget and see a world map of where flights are cheapest right now from your city.
- Filter for flexibility. Select ‘Anytime’ or ‘Flexible Dates.’ This tells the algorithm you are looking for the best deal rather than a specific day.
- Set price alerts. If you have a specific destination in mind, toggle the ‘Track Prices’ switch. You will get a notification when fares on that route change.
- Compare cabin classes. Use the filter to check ‘Premium Economy’ or ‘Business.’ Now and then, a premium seat costs less than you would expect.
Once you find a fare you like, click through to the provider. The app will redirect you to the booking page. Always double-check the baggage rules before you finalize the payment.
Destinations with plenty of fare options
Busy hubs with many daily flights tend to have more competition between airlines, which can mean more fare options.
• London, United Kingdom. Heathrow and Gatwick handle a high volume of traffic, with many competing flights to the rest of Europe. Bangkok, Thailand. A major international gateway where shoulder-season fares can offer good value.
• New York City, USA. The high frequency of flights to and from Europe gives travelers many fare options on popular transatlantic routes.
• Orlando, USA. Because this is a leisure-heavy destination, midweek flights are often cheaper than weekend ones, which helps families save.
Want a proven strategy? Try visiting these destinations when everyone else isn’t. You’ll snag the same perks for way less money. It’s also worth checking out specific tips on how to get cheap flights if you’re a student trying to see the world.
Smaller, secondary airports are also worth checking, since budget airlines often fly from them at lower fares. It’s always a smart idea to check nearby cities when you’re planning your trip.
Tips for finding a better fare
Timing matters, but not the day you shop: Google’s analysis found that buying on a Tuesday, Wednesday or Thursday instead of a weekend saved only about 1.9% on average. The day you fly matters more, since Monday to Wednesday departures averaged about 12% less than weekend departures.
• Compare more than one search tool. The same flight can be priced differently on different booking sites.
• Be flexible with dates and airports. Shifting your trip by a day or two, or flying from a nearby airport, often makes a bigger difference than waiting.
• Check one-way tickets. Sometimes buying two separate one-way tickets on different airlines is cheaper than a single round-trip.
• Travel light. Many of the lowest fares are on budget carriers that charge for bags, so check what is included before you book.
Another tip is to monitor ‘Empty Leg’ flights if you are interested in private or smaller regional carriers. While rarer, these offer a similar logic where the plane must fly anyway, making the remaining seats cheaper.
Finally, keep your notifications on, since a good fare may not last long.
The smart traveler’s approach: plan ahead and stay flexible
Tracking prices is one of the easiest ways to avoid overpaying for flights. Use the KAYAK app to keep an eye on fares, stay flexible with your dates and book when the price fits your budget, ideally weeks rather than days before you fly.
This approach works for anyone who values both quality and affordability during their travels.
Good fares do appear, and an alert is the simplest way to catch them without checking prices every day.

Frequently Asked Questions (FAQs)

Which travel app helps track flight price drops?▾
KAYAK is a popular option because it compares fares from many airlines and booking sites, and its alerts tell you when the price on your route changes.
Do price drops happen on long-haul international flights too?▾
Yes, fares on international routes go up and down as well. For trips from the U.S. to Europe, Google’s analysis found that prices have tended to be lower 50 to 179 days before departure, so international trips usually reward booking well ahead.
Is there a specific day during the week that’s best for finding these flight deals?▾
The day you buy matters little: Google found that shopping on a Tuesday, Wednesday or Thursday saved only about 1.9% on average compared with the weekend. The day you fly matters more, since Monday to Wednesday departures averaged about 12% less than weekend departures.
Are baggage fees included in discounted fares?▾
Not typically. Most of the time, low fares cover only the base ticket. Check the airline’s baggage rules before you book so you don’t pay extra fees you didn’t plan for.
