Whether it’s a spontaneous escape or a necessary emergency trip, last-minute flights can be brutally expensive, unless you know a few tricks. Scoring a great deal often comes down to flexibility, smart tools, and knowing how the system works. Here are nine insider tips that’ll help you beat the high prices and book that flight without draining your wallet.
Stay Flexible With Your Travel Dates

Rigid schedules will cost you. The more flexible you are with departure and return dates, the better chance you have of landing a low fare. Try flying on weekdays, especially Tuesdays, Wednesdays, or Thursdays, when prices are often lower due to less demand. Use fare calendars on sites like Google Flights or Kayak to compare prices across an entire month. Often, leaving just a day earlier or later can save you a surprising amount.
Consider Alternate Destinations

If your destination isn’t set in stone, you’ve got a huge advantage. Being open to multiple cities—or even countries can unlock cheaper options. Airlines often discount flights to places with low demand, so keep your eye on where the deals are. Use tools like Skyscanner’s “Everywhere” search or Expedia’s app-based deal finders to browse discounted locations based on your departure point.
Set Price Alerts and Use Deal Trackers

Don’t waste time checking prices 10 times a day. Set alerts using Google Flights, Kayak, or Skyscanner to track routes you’re interested in. These tools notify you when prices drop, helping you swoop in fast. You can also use services like Dollar Flight Club or Airfarewatchdog to get real-time deal alerts. Some of these even track flash sales or mistake fares, giving you a chance to grab serious bargains within minutes.
Bundle Flights and Hotels Together

When booking both a flight and a hotel, try bundling them through travel platforms like Expedia or Priceline. These packages are often priced cheaper than booking separately. In some cases, bundling can slash hundreds off the total. Even if you’re booking at the last minute, many platforms show same-day bundle deals that let you save without sacrificing decent accommodation or good flight times.
Search Nearby Airports

Don’t just limit yourself to one airport—cast a wider net. Big cities usually have multiple airports, and fares can vary dramatically depending on which one you choose. For example, flying into Oakland instead of San Francisco, or Newark instead of JFK, can often save you money. Apply the same logic to your departure: if you’re willing to drive a bit farther to take off, you might land a cheaper seat.
Book One Way Flights With Different Airlines

Mixing and matching one-way flights on different airlines can sometimes be cheaper than booking a round trip. This trick opens up opportunities to combine budget carriers with major airlines or take advantage of separate flash sales. Plus, you get more flexibility with your return plans. Just be sure to compare all fees, including baggage, so you don’t get blindsided by hidden costs.
Fly Red Eye to Save Big

Red-eye flights those that depart late at night and arrive early in the morning tend to be less in demand. That means cheaper fares. If you don’t mind losing a bit of sleep, you can often save significantly and arrive at your destination with the full day ahead of you. Bonus: airports are usually less chaotic at night, so the travel experience may be smoother.
Add a Layover or Stopover

Nonstop flights are faster, but not always the cheapest. Choosing an itinerary with one or two layovers can lower the fare substantially. Many airlines also offer free stopovers in their hub cities, letting you spend a day or two exploring a new destination without added ticket costs. If you’re not in a rush, this is a great way to stretch your budget and your trip.
Look Into Budget Airlines

Budget carriers like Spirit, Frontier, Allegiant, and Breeze often have dirt-cheap base fares especially for last-minute travel. But beware: these low fares usually don’t include extras like seat selection, carry-ons, or snacks. Read the terms before booking to make sure you know what you’re actually paying for. If you can travel light and go without the frills, this is often the best way to fly on a budget.
