What is the cheapest website to book international flights?

Timing is key - flights booked 4-6 months in advance tend to be the cheapest, while last-minute flights can cost significantly more.

Weekday flights, especially Tuesdays and Wednesdays, are generally less expensive than weekend flights.

Flying during the "shoulder season" (the periods between peak and off-peak travel seasons) can lead to substantial savings.

Budget airlines like Spirit, Frontier, and Allegiant may have ultra-low base fares, but watch out for added fees that can drive up the total cost.

Frequent flyer programs and credit card rewards can be leveraged to score free or discounted flights, especially for international travel.

Flying with a stopover or layover, rather than a direct flight, can sometimes be cheaper, though it adds travel time.

Clearing your browser cookies and searching incognito mode may help you avoid dynamic pricing that raises fares based on your browsing history.

Booking one-way flights separately rather than roundtrip can lead to savings, especially if your departure and return dates are flexible.

Consider flying into or out of smaller, regional airports near your final destination, as they often have lower fares than major hubs.

Using a flight price prediction tool like Hopper can help you time your purchase to get the best deal.

Travel deal sites like Scott's Cheap Flights and Airfarewatchdog send alerts for mistake fares and limited-time flash sales.

Booking directly with the airline, rather than a third-party site, may qualify you for perks like free checked bags or seat selection.

Airline pricing algorithms use complex models to adjust fares based on demand, so booking at the right time can make a big difference.

Flying during the off-season, when demand is lower, can result in significant savings compared to peak travel periods.

Joining airline loyalty programs and using their affiliated credit cards can unlock discounts, upgrades, and other benefits.

Paying in a foreign currency, if the option is available, may sometimes be cheaper than paying in your home currency.

Flexible travel dates, even by a day or two, can open up more affordable flight options.

Searching for flights on a VPN or from a different geographic location may yield different pricing.

Considering alternate airports near your desired destination can sometimes reveal cheaper flight options.

Understanding the airline's baggage policies and packing light can help you avoid costly add-on fees.
