Best Day to Book Flights: Smart Tips to Save on Airfare

You’ve probably seen it happen, you refresh a flight search, and suddenly the ticket price jumps from $340 to $410within minutes. It feels frustrating and random, but there’s logic behind it. Flight prices are dynamic, changing multiple times a day based on demand, availability, and search activity.

Knowing when to book can help you save $50 to $150 on the same route without using any special hacks. Timing your purchase isn’t guesswork, it’s a pattern that airlines follow throughout the year.

In this blog, you’ll discover why fares fluctuate, which days of the week deliver better prices, and how you can combine timing, flexibility, and smart tools to pay less every time you fly.

Why Does the Day You Book Flights Matter So Much?

Airlines constantly adjust prices depending on how many people are searching, how full a plane is, and what day it is. A flight that costs $360 today might rise to $420 tomorrow or fall back to $340 next week.

Here’s why this happens:

  • Demand and Holidays: Prices rise around national holidays and long weekends when travel demand spikes.
  • Advance Planning: Booking far too early or too late usually leads to paying more.
  • Competitor Pricing: When one airline launches a sale, others follow to stay competitive.

Travel data shows that booking on the right day can save you 5% to 25%, especially when you match the correct booking day with the best day to fly. Over a year, that can mean hundreds of dollars saved, simply by understanding timing.

What Do Studies Say About the Best Day to Book Flights?

Multiple studies confirm that your booking day matters more than you think. According to Expedia’s 2025 Air Travel Hacks Report, travellers who booked on Sundays instead of Fridays saved an average of 17%. Google Flights also found Sunday bookings to be cheaper for both domestic and international trips.

But remember, there’s no single “magic day.” Airlines tweak fares several times daily, so flexibility is still your best advantage.

Here’s what research reveals:

  • Domestic Flights: Book 1 to 3 months before travel to save around 25%.
  • International Flights: Best fares appear 18 to 29 days before departure.
  • Sunday Edge: Sunday purchases consistently show savings across both economy and business classes.

By pairing the right day with early planning, you can make sure you’re not spending more than necessary on your next trip.

Is There Really a Best Day of the Week to Book Flights?

For years, people believed Tuesday was the golden day for cheap flights. While that used to be true, newer data points to Sunday as the better option overall.

Still, early-week bookings can work in your favour if you’re flexible. Here’s a quick overview of average savings and timelines:

  • Domestic Economy: Average savings ≈ 5%; book 30–45 days before travel.
  • Domestic Business: Average savings ≈ 7%; book 40–60 days ahead.
  • International Economy: Average savings ≈ 5%; book 18–29 days ahead.
  • International Business: Average savings ≈ 24%; book 2–3 months in advance.

Booking early on a Sunday morning often reveals discounted seats that haven’t yet been snapped up. On the other hand, late Friday nights and busy weekend afternoons tend to show inflated prices because more travellers are browsing at that time.

When Is the Best Time of Day to Book Flights for Cheaper Deals?

The time you search can make as much difference as the day itself. Airlines refresh their systems overnight, releasing updated fares and limited-time promotions.

Try checking during these windows:

  • Early Morning (5 a.m.–8 a.m.): Freshly updated inventory and lower competition.
  • Late Night (after 9 p.m.): Fewer active searches reduce demand-driven price spikes.
  • Avoid Evenings (5 p.m.–8 p.m.): Most people book after work, pushing fares up temporarily.

If you combine both strategies, booking early Tuesday morning or late Sunday night, you’ll often see fares up to $60 cheaper on average. Being strategic with timing is one of the simplest ways to make travel more affordable.

Do Seasons and Months Affect Flight Prices?

Absolutely, airfare changes with the seasons, just like hotel rates or holiday packages. Airlines raise prices when more people want to fly and lower them when demand drops. Knowing the right travel months can help you plan smarter and save a good chunk of money.

Here’s what travel data shows:

  • August: Often the cheapest month to fly, especially for domestic trips.
  • February & March: Usually the most expensive months, with fewer promotional fares.
  • September–October: Known as the “shoulder season,” where fares drop up to 40% after summer ends.
  • Holiday Periods: Thanksgiving, Christmas, and New Year’s always come with steep surcharges, sometimes double the usual fare.

If you’re planning holiday travel, aim to book before late October. Prices rise sharply after that as families start confirming their festive trips.

Which Airlines Offer Cheap Tickets, and Are They Worth It?

Low-cost carriers might catch your eye with incredibly cheap prices, but not all deals are equal. Airlines like Spirit, Frontier, and Avelo offer discounted base fares that often exclude luggage, seat selection, or onboard refreshments.

Before booking, it’s worth asking yourself whether the savings justify the trade-offs.

Smart checks before choosing:

  • Compare the total cost, include baggage and add-ons.
  • Check carry-on policies, some low-cost carriers charge even for a small bag.
  • Review schedule reliability, cheaper flights can have longer layovers or higher cancellation risk.

Sometimes, paying $20–$30 more for a major airline such as Delta, Southwest, or American gives you perks like free baggage, better timing, and customer support, often worth the small extra cost.

What Tools and Tricks Help You Find the Best Airfare?

Thankfully, today’s traveller has several tools that make price-tracking effortless. Instead of manually checking every day, you can let smart apps do the work.

Here are a few that help you stay ahead:

  • Google Flights: Monitors routes and sends alerts when fares drop.
  • Hopper App: Uses colour codes and predictions to show when to buy or wait.
  • Travelpodium: Offers live fare comparisons, exclusive deals, and refund guarantees if ticket prices fall later.
  • Price Alerts: Set automatic notifications for your preferred destinations.

Spending just five minutes a week checking these platforms can save you hundreds of dollars annually, far more than waiting for random “flash sales.”

How Can You Save More with Smart Flight Booking?

Finding the best day to book flights isn’t about luck, it’s about spotting patterns. Once you understand how airlines adjust fares, you can book confidently without second-guessing your timing.

Follow these key steps:

  • Book about 34 days ahead for domestic flights.

Quick Answers to Common Questions

According to recent data, Sunday usually offers the lowest average prices for both domestic and international flights. Booking on Sunday morning or late at night often reveals the best deals before others spot them.

For domestic routes, aim to book around 30–45 days before your trip. This window helps you avoid both last-minute price surges and early high fares.

The best times are early morning (5 a.m.–8 a.m.) or late night (after 9 p.m.). During these hours, airlines refresh their systems and demand is lower, making prices slightly cheaper.



Yes. Airlines adjust prices several times a day based on seat availability, route demand, and online search activity. Even checking at different times on the same day can show a $20–$70 difference.



Tuesday used to be the cheapest day, but now Sunday and early Tuesday mornings generally offer better prices. Airlines have changed their pricing cycles to match global booking patterns.



You can set price alerts on websites like Travelpodium, Google Flights, or Hopper. These tools automatically send notifications when fares fall for your chosen route.



Comparison sites like Travelpodium display prices from multiple airlines in one place. This helps you see the best available deals and avoid missing hidden discounts that single-airline sites may not show.

Not usually. Prices often rise as the departure date nears because of limited seat availability. Only a few last-minute sales occur, and they’re rare for popular routes.



International fares depend on global demand, fuel costs, and seasonal events. For example, summer and holiday seasons raise prices, while August and October often bring cheaper international deals.

Travelpodium compares fares from multiple airlines in real time, highlights price trends, and provides refund options if fares drop later. It helps you book confidently without spending hours searching across different sites.
