Best Day to Buy Airline Tickets for the Cheapest Fares

Two of the best ways to find a good deal on airline tickets are to know the “Best Day to Buy Airline Tickets” and be aware of price alerts. By understanding the optimal timing to purchase, you can save significant money on your flights.

Booking at the right time is crucial to securing the cheapest fares for your flights. Savvy travelers increase their chances of snagging a great deal by watching price trends and understanding the best day of the week to book. You can save money by booking flights at certain times, but it’s more about when you book than what time of day. Here’s what recent data shows:

  • Best Day to Buy Airline Tickets: According to a 2025 Expedia study, Sunday is the cheapest flight day. Booking on a Sunday instead of a Monday or Friday can save you around 6% on domestic flights.

  • Best time in advance:
    • For domestic flights, book 1–2 months ahead.
    • For international travel, aim for 3–5 months in advance.
  • Best days to fly: Flying on Tuesdays or Wednesdays often yields lower fares due to reduced demand
  • When to Fly: If possible, avoid traveling during peak periods, as airlines raise their prices during the peak season.

Generally, booking your flight around six to eight weeks before your departure date yields lower prices. Also, midweek flights are typically cheaper than weekend flights, so please keep that in mind when planning your travel. By being strategic about when you book your tickets, you can maximize your savings and make your travel budget go further.

Take Advantage of Loyalty Programs to Get Best Deals on Airline Tickets

One of the best strategies to get Best Deals on Airline Tickets is to take advantage of frequent flyer programs and use points. Many airlines offer loyalty programs allowing you to earn points or miles every time you fly and use their airline credit cards.. By signing up for these programs with your preferred airline, you can accumulate points that can be redeemed for future flights or other travel perks. This can help you save money on airfare in the long run, so it’s worth considering when booking your next trip. Please look at our post on Frequent Flyer Loyalty Programs to learn more. Here are some of our recommended programs:

Alaska Airlines Book a Flight

Alaska Airlines offers a loyalty program called Mileage Plan, which allows you to earn miles for future travel with every flight you take. By signing up for the Program, you can start earning miles and enjoying benefits when you use Alaska Airlines to book a flight.  Compared to competitive airlines, you will get a better deal when you use Alaska Airlines to book a transatlantic flight with a partner airline when departing from the East Coast.

Comparing Prices Across Different Airline Booking Sites

When finding the best deals on airline ticket prices, comparing prices across airline booking sites is key. Each site may offer varying prices based on factors like demand, availability, and promotions. By taking the time to compare prices on multiple platforms, you can ensure that you are getting the best possible deal for your next flight. Next, let’s take a look at some of the best airline booking sites to consider when searching for your next travel adventure.

Best Site to Book Flight Tickets

Google Flights and Expedia are two of the best sites to book flight tickets:

  • Google Flights is a powerful travel search tool that helps you find, compare, and book flights across hundreds of airlines. Here’s what makes it stand out:
    • Price tracking: You can monitor fares for specific routes and get email alerts when prices drop
    • Date grid & price graph: These tools show you the cheapest days to fly, making it easy to save money if your schedule is flexible
    • Insights & predictions: Google uses historical data to suggest whether prices are likely to rise or fall
    • Filters galore: To tailor your search, you can sort by airline, number of stops, baggage policies, and more.
  • Expedia: This comprehensive booking site allows you to search for flights, hotels, vacation packages, and more, all in one place. Using Expedia, you can easily compare prices, view different airlines, and take advantage of package deals combining flights and lodging that save you even more money on travel expenses.

For booking U.S. domestic flights, several websites consistently stand out for price, features, and ease of use. Here are the top contenders for 2025:

🥇 Google Flights

  • Best for: Price tracking, flexible dates, and speed.
  • Why it’s excellent: Clean interface, powerful filters, and predictive pricing insights.
  • Bonus: You can book directly with the airline—no middleman.

🥈 Skyscanner

  • Best for: Finding the cheapest fares across multiple airlines and OTAs.
  • Why it’s excellent: Flexible search options (like “cheapest month”) and fare alerts.

🥉 Kayak

  • Best for: Comparing deals and using tools like “Price Forecast” and “Explore.”
  • Why it’s excellent: Searches hundreds of sites and offers bundled travel options.

Each has strengths, but Google Flights is hard to beat if you want speed, transparency, and direct booking.

One-Way Fares vs Round-Trip Fares

Are one-way flights more expensive than Round-trip fares? It depends on where you’re flying and which airline you’re using—but here’s the general rule:

  • In the U.S. domestic market, one-way fares are usually priced the same as half a round-trip. So booking two one-way trips costs about the same as a round trip. This is thanks to competition from low-cost carriers and more flexible pricing models.
  • For international flights, one-way tickets can be significantly more expensive—sometimes 2–3 times the round-trip cost. Airlines often lower round-trip fares to encourage loyalty and discourage travelers from mixing carriers.

So one-way is often just as economical if you’re flying within the U.S.. But round-trip is usually the better deal if you’re flying abroad, unless you’re using points or miles, where pricing is more flexible. Open-jaw itineraries, where you fly internationally into one city and depart from another, can sometimes cost no more than a full round-trip fare. You still need to search to see if you’re able to arrange it.

Direct Flights vs Connecting Flights

In general, connecting flights are often less expensive than nonstop flights, but it depends on a few key factors:

  • Airline pricing strategies: Airlines may offer lower fares on connecting routes to fill more seats or compete on price-sensitive routes.
  • Route popularity: Direct flights on high-demand routes (like NYC to LA) can be more expensive due to convenience and limited availability.
  • Time vs. money trade-off: Connecting flights usually take longer and involve layovers, but depending on the route, they can save you $50–$150 or more.
  • Hidden costs: If a layover is long, you might spend more on food, airport hotels, or risk delays, so the savings aren’t always worth it.

For example, a direct flight might cost $300 and take 2 hours, while a connecting flight could be $200 but take 4–6 hours. If you’re flexible and want to save money versus time, connecting flights can produce the lowest prices. But if time and convenience matter more, direct is often worth the premium.

Low-cost Carriers (Budget Airlines)

Low-cost carriers (LCCs) are most effective for domestic travel. Here’s a breakdown of countries where low-cost airlines impact flight prices:

United States

  • Highly effective: Carriers like Southwest, Frontier Airlines, Allegiant, and JetBlue offer extensive domestic networks.
  • Why it works: Large landmass, high demand for internal travel, and deregulated airspace.

India

  • Extremely effective: IndiGo, SpiceJet, Akasa Air, and Air India Express dominate domestic routes.
  • Why it works: Huge population, growing middle class, and limited rail alternatives for long distances.

European Union (especially Spain, Italy, France)

  • Moderately effective: LCCs like Ryanair, easyJet, Volotea, and Vueling operate many intra-country flights, especially in Spain and Italy.
  • Why it’s mixed: High-speed trains compete with short-haul flights in countries like France and Germany.

Brazil

  • Effective: GOL and Azul serve many domestic routes across Brazil’s vast geography.
  • Why it works: Limited road and rail infrastructure between major cities.

Indonesia

  • Very effective: Lion Air, Citilink, and AirAsia Indonesia connect the archipelago’s many islands.
  • Why it works: Air travel is often the only practical option between islands.

Philippines

  • Effective: Cebu Pacific and Philippines AirAsia dominate domestic air travel.
  • Why it works: Similar to Indonesia—air travel is essential between islands.

In contrast, countries like Japan, Germany, and the UK have less domestic LCC dominance due to excellent rail systems or smaller geographic size. In the next section, we will discuss some tips for securing last-minute deals on airline tickets.

Tips for Last-Minute Flights

If you need a last-minute flight, there are still ways to score a great deal on airline tickets. One tip is to be flexible with your travel dates and times. Airlines often offer discounted fares for flights departing soon or during off-peak hours. By being open to different options, you may be able to find a more affordable ticket.

Another strategy is to sign up for fare alerts from various airlines or booking sites. These alerts will notify you when there are price drops or special promotions for flights to your desired destination. By staying informed, you can pounce on a deal as soon as it becomes available.

Additionally, consider booking a flight with a budget airline. These carriers often have lower fares than major airlines, especially for last-minute bookings. While you may have to forgo some amenities, you can save a significant amount of money on your ticket.

By following these tips for securing last-minute deals on airline tickets, you can make the most of your travel budget and find affordable flights even when time is of the essence. Keep these strategies in mind the next time you need to book a flight quickly and you will be satisfied with the results.

Conclusion

In conclusion, by using online tools effectively, booking at the right time, and taking advantage of loyalty programs, you can secure the best deals on airline tickets. Remember to compare prices across different websites and keep an eye out for last-minute deals. Start implementing these strategies today by checking out Expedia, and watch your savings soar.
