How to Find Cheap Flights From Boston Logan Airport (2026)

Finding cheap flights from Boston Logan Airport (BOS) is straightforward when you know which days to book, how far in advance to plan, and which budget carriers to target. Whether you’re planning a trip months in advance or need to catch a last-minute flight, there are strategies you can use to secure the best deal. Here’s how to find cheap flights from Boston Logan Airport, including expert tips on when to book, how to get the best deals, and the cheapest times to fly.

What Is the Best Day to Buy Airline Tickets?

If you’re wondering when to book your flight, the answer is clear: Sunday is typically the best day to buy. According to data from ARC and Expedia Group, ticket prices are typically lower when booked on Sundays—sometimes up to 36% cheaper than booking mid-week.

For domestic flights, Saturday is another good option, according to Skyscanner. The takeaway is simple: book on Sunday first, Saturday second, and avoid mid-week purchases when prices tend to peak.

What Time of Day Is Best to Book Cheap Flights from Boston Logan Airport?

The time of day has less impact on price than the day or season, but booking early morning or late night can occasionally surface lower fares before airlines adjust pricing.

Early Morning (6 AM): Skyscanner recommends searching for flights at 6 AM, when airlines often release new fares.
Afternoon (3 PM): FareCompare suggests that Tuesday afternoons around 3 PM are prime booking times.

These windows may give you a slight edge, but day-of-week and seasonal timing remain the dominant drivers of fare prices.

When booking international flights from Boston Logan, experts recommend:

Sunday is the best day to book, according to Skyscanner.
Four Months in Advance: For the best deals on international flights, it’s best to book four months ahead of time. This provides you with more options and a better chance of securing a reasonable price.

How Far in Advance Should I Book a Flight to Get the Best Deal?

Booking at the right time is the single biggest lever for finding cheap flights from Boston Logan. ARC and Expedia Group suggest booking at least three weeks in advance for both economy and premium tickets to get the best prices. CheapAir agrees, recommending that travelers aim to book their flights three to four months in advance.

The earlier you book, the more likely you are to find the lowest airfare, so don’t wait until the last minute if you want to secure a budget-friendly flight.

How Can I Get Cheap Flights Last Minute?
