Finding cheap flights is easier when you know where to look. Many websites and apps specialize in tracking airfare deals, comparing prices, and even alerting you when prices drop. Whether you’re booking a last-minute flight or planning months in advance, these platforms can help you save money on your next trip.

Here are the best websites and apps to buy cheap flights and how to use them effectively.

1. Google Flights (Best for Quick Searches & Price Tracking)

Google Flights is one of the most powerful tools for finding cheap flights. It allows you to:

✅ Compare prices from multiple airlines in seconds.
✅ Track price changes and receive alerts when fares drop.
✅ Use the “Explore” feature to find cheap destinations based on your budget.
✅ Check flexible date options to find the lowest fare.

💡 Pro Tip: After finding a cheap flight on Google Flights, book directly through the airline to avoid third-party fees.

2. Skyscanner (Best for Flexible Travelers)

Skyscanner searches millions of flights to find the cheapest options, often including budget airlines that Google Flights may not display.

✅ Search “Everywhere” to find the cheapest destinations from your location.
✅ Check the “Whole Month” view to see which days have the lowest fares.
✅ Filter by airlines, layovers, and travel duration.

💡 Pro Tip: Skyscanner sometimes shows fares that are cheaper when booked through third-party agencies. Always check airline policies before booking.

✅ Great for multi-city trips.
✅ Includes budget airlines and smaller booking sites.
✅ Can find cheaper fares than Google Flights in some cases.

💡 Pro Tip: Some fares on Momondo are from third-party agencies, so double-check cancellation policies before booking.
