Why Book International Flights to the USA in 2025?
The USA remains one of the most popular travel destinations for international visitors, offering diverse experiences from coast to coast.
In 2025, the travel industry is expected to rebound further, with airlines introducing new routes, competitive pricing, and promotions to attract global travellers. Whether you’re coming from Europe, Asia, Africa, or Australia, there are plenty of opportunities to snag affordable flights.
But with so many options, how do you find the best deals? Let’s explore the top strategies.
1. Timing Is Everything: When to Book for the Cheapest Flights
One of the most critical factors in securing cheap international flights to the USA is knowing when to book. Timing your booking correctly can save you hundreds of dollars. Here’s what you need to know:
Book Early, But Not Too Early
- 6–12 months in advance: For international flights, booking 6 to 12 months ahead often yields the lowest prices, especially for peak travel seasons like summer or the holidays.
- Avoid last-minute bookings: Prices tend to skyrocket within two weeks of departure, so plan ahead to avoid premium fares.
- Midweek sweet spot: Airlines often release discounted fares on Tuesdays and Wednesdays, so check flight prices midweek for the best deals.
Travel During Shoulder Seasons
The USA has distinct travel seasons, and flying during less busy periods can save you big:
- Spring (April–May): Mild weather and fewer crowds make this a great time to visit cities like Chicago or San Francisco.
- Fall (September–October): Autumn offers pleasant temperatures and lower airfares, especially to destinations like Boston or Seattle.
- Avoid peak seasons: Summer (June–August) and winter holidays (December–January) are the most expensive times to fly.
Be Flexible with Dates
Flexibility is key to finding cheap flights. Use tools like Google Flights or Skyscanner to compare prices across a range of dates. Many platforms offer a “flexible dates” feature that shows you the cheapest days to fly within a month.
2. Choose Budget-Friendly Departure Cities
Your departure city plays a significant role in the cost of your flight to the USA. Major international hubs often have more flight options and lower prices due to competition among airlines. Here are some tips:
Fly from Major Hubs
- Europe: Cities like London, Paris, Amsterdam, and Frankfurt often have affordable flights to the USA due to high competition.
- Asia: Tokyo, Seoul, Bangkok, and Singapore are great departure points with frequent deals to Los Angeles, New York, or Chicago.
- Africa: Johannesburg, Lagos, and Nairobi often have competitive fares to US cities like Atlanta or Washington, D.C.
- Australia: Sydney and Melbourne frequently offer deals to Los Angeles or San Francisco.
Consider Nearby Airports
If you’re not near a major hub, check flights from nearby cities. For example, if you’re in Manchester, UK, compare prices from Manchester and London airports. Driving or taking a short flight to a larger hub can save you hundreds.
3. Use Flight Comparison Tools to Find the Best Deals
Technology is your best friend when hunting for cheap international flights. Here are the top tools to help you find budget-friendly airfare in 2025:
Google Flights
Google Flights is a powerful tool that lets you compare prices across airlines, dates, and routes. Its “Explore” feature shows you the cheapest destinations in the USA from your departure city, which is perfect if you’re flexible about where to go.
Skyscanner
Skyscanner’s “Everywhere” search option is ideal for finding the cheapest US destinations. You can also set price alerts to get notified when fares drop.
Kayak
Kayak offers a user-friendly interface and a “Price Forecast” tool that predicts whether flight prices are likely to rise or fall, helping you decide when to book.
Momondo
Momondo is great for finding deals on lesser-known airlines and routes. Its calendar view makes it easy to spot the cheapest travel days.
Pro Tip: Clear Your Browser Cookies
Some travel sites track your searches and may increase prices based on demand. Use incognito mode or clear your cookies to ensure you’re seeing the lowest fares.
4. Leverage Budget Airlines and Layovers
Budget airlines and strategic layovers can significantly reduce the cost of international flights to the USA. Here’s how to make the most of them:
Fly with Low-Cost Carriers
Many budget airlines now offer long-haul flights to the USA at a fraction of the cost of legacy carriers. Examples include:
- Norwegian Air: Offers affordable transatlantic flights from Europe to cities like New York and Los Angeles.
- WOW Air: Known for cheap fares from Europe to the USA, often with a stopover in Iceland.
- AirAsia: Provides budget-friendly options from Asia to the USA via connecting flights.
- Jetstar: A great choice for travelers from Australia or New Zealand.
Embrace Layovers
Flights with layovers are often cheaper than nonstop routes. Consider routes with stopovers in hubs like Dubai, Istanbul, or Doha, which can save you money and even allow you to explore an extra city. Just ensure your layover is long enough to clear customs but short enough to avoid wasting time.
5. Join Airline Loyalty Programs and Use Miles
Frequent flyer programs and travel reward credit cards can help you save big on international flights. Here’s how to make them work for you:
Sign Up for Airline Alliances
Major airline alliances like Star Alliance, Oneworld, and SkyTeam allow you to earn and redeem miles across multiple carriers. For example:
- Star Alliance: Includes airlines like United, Lufthansa, and Air Canada.
- Oneworld: Includes American Airlines, British Airways, and Qantas.
- SkyTeam: Includes Delta, Air France, and KLM.
Use Credit Card Points
Travel credit cards often offer sign-up bonuses that can cover a significant portion of your flight cost. Cards like the Chase Sapphire Preferred or American Express Platinum allow you to transfer points to airline partners for maximum value.
Redeem Miles Strategically
Check for “sweet spot” deals when redeeming miles. For example, using miles for international flights during off-peak seasons often requires fewer points, stretching your rewards further.
6. Look for Special Deals and Promotions
Airlines and travel agencies frequently offer promotions that can slash the cost of international flights. Here’s how to stay in the loop:
Subscribe to Airline Newsletters
Sign up for newsletters from airlines like Delta, United, Emirates, or Qatar Airways to receive exclusive deals and flash sales.
Follow Deal Websites
Websites like The Flight Deal, Secret Flying, and Scott’s Cheap Flights specialize in finding and sharing limited-time flight deals to the USA.
Check Social Media
Follow airlines and travel deal accounts on platforms like X for real-time updates on fare drops and promotions. Many airlines announce flash sales on social media first.
7. Consider Alternative US Airports
Flying into smaller or secondary airports in the USA can save you money. For example:
- Instead of JFK (New York): Fly into Newark (EWR) or LaGuardia (LGA).
- Instead of LAX (Los Angeles): Consider Long Beach (LGB) or Ontario (ONT).
- Instead of Miami (MIA): Check flights to Fort Lauderdale (FLL).
These airports often have lower landing fees, which can translate to cheaper tickets. Just factor in ground transportation costs to your final destination.
8. Avoid Hidden Fees
Budget airlines often advertise low base fares but add fees for baggage, seat selection, and other services. To avoid surprises:
- Read the fine print before booking.
- Pack light to avoid checked baggage fees.
- Bring your own snacks to skip expensive in-flight purchases.
