Last Updated on Aug 13th, 2025 by Neha Sharma, Leave a Comment

Thinking about booking a flight & unsure when to lock in your tickets? You’re not by yourself! The time of your flight reservation can have a significant impact on cost, availability, & comfort, if you’re flying domestically within the US or abroad to places like India. “When is the best time to buy airfare?” and “How far in advance should I book a flight?” are frequently asked questions by tourists.

We’ve created a comprehensive guide that provides accurate information, practical advice, & the most recent travel trends to help you avoid last-minute expensive tickets & limited seat options. Let’s take a closer look at the ideal time to book your next flight before you finalize your schedule.

When do you usually book your international flights?

• Less than 1 month before departure
• 1-2 months in advance
• 3-4 months in advance
• 5-6 months in advance
• As soon as I decide to travel

Why Booking in Advance Matters? 

Airlines employ dynamic pricing, which means that the cost of tickets varies according to demand, seat availability, seasons, & even the frequency of searches. While booking too late frequently results in paying higher last-minute rates, booking too early may result in missing out on discounts.

The ideal time to book is usually one to three months before departure for domestic flights & three to six months before departure for international flights, particularly those from the USA to India. You can find more seat options & better prices if you book during these times. 

How Far in Advance Should You Book Domestic Flights?

For domestic travel within the United States:

Time Before Departure	Fare Trend
5 to 6 Months ahead	Often too early – prices can be higher
2 to 3 months ahead	Best time to book, usually the cheapest fares
Last-minute (0-2 Weeks)	Highest prices, fewer options

What Is The Best Time to Book? 

Domestic flights are cheapest when booked between 60 to 90 days (2–3 months) in advance.

Example: If you’re planning a trip from New York to Los Angeles, booking your ticket 2–3 months in advance can save you up to 15–20% compared to last-minute rates.

How Far in Advance to Book International Flights?

For international flights, like USA to India, you should book even earlier to grab the best fares & seat options.

Time Before Departure	Fare Trend
8-11 months ahead	Available, but not always the cheapest
5-6 Months ahead	Ideal window for best fares
1 Month or less	Limited seats, high prices

Book International Flights 5–6 Months in Advance

If you’re flying internationally, like from Chicago to Delhi, booking your ticket 5 – 6 months ahead can help you save 25–30% compared to booking during peak season. Airlines release cheaper seats earlier, & as the travel date gets closer, prices usually go up.
Booking early also gives you more options for seats, timings, and better connections.
So, start checking fares early to lock in the best deals.

How Far Out Can You Book a Flight?

Most airlines open their booking window 11 months in advance. This means you can reserve travel tickets almost a year ahead, but that doesn’t always mean those are the lowest prices.

Booking Window	Flight Availability
330-360 Days	Flights are released, but often expensive
180 Days	Prices begin to stabilize
90-150 Days	Best fare window for most routes

When Is the Best Time to Buy Airfare?

There’s no one-size-fits-all answer, but here’s a general guide:

• Domestic Flights (USA): 1.5 to 3 months before travel.
• International Flights: 4 to 6 months before travel.
• Holiday Season Travel: 6+ months in advance.
• Off-Peak Season Travel: 2–4 months in advance.

Best Days to Book Flights

Many experts say Tuesday or Wednesday are the best days to book flights, as airlines often release weekly deals early in the week.

• Avoid booking on weekends, as prices can surge due to high demand.
• Booking flights early in the morning may also give you better prices.

Booking Flights from USA to India – A Real Example

If you’re traveling from New York to Delhi, Chicago to Chennai, San Francisco to Mumbai, or Dallas to Bangalore, booking 5 – 6 months in advance offers better flexibility, lower fares, and more flight options with airlines such as Air India, United Airlines, and Emirates.

Additionally, during peak seasons such as summer, Diwali, or Christmas, flights from the USA to India can sell out months in advance, so don’t wait until the last minute.

What Influences Flight Prices?

• Seasonal Demand – Summer and holidays bring high fares.
• Fuel Prices & Airline Costs
• Destination Events – Festivals, holidays, or conferences in your destination increase prices.
• Number of Stopovers – Non-stop flights are usually more expensive than flights with layovers.
