3. Set Price Alerts & Book at the Right Time
Flight prices fluctuate constantly, but you can track them and strike when the price drops.
- Use Hopper or Skyscanner alerts to monitor fares

4. Consider Budget Airlines (and Know the Trade-offs)

- Always compare the total cost, not just the base fare
- Pack light to avoid baggage fees
- Read the fine print before booking—some budget airlines fly to remote airports

5. Use “Incognito Mode” When Searching Flights
Flight search sites often use cookies to track your behavior and might increase prices if you search the same route multiple times.
- Open an incognito/private browser window
- Clear your cache and cookies regularly
- Use a VPN to compare prices from different regions—flights can be cheaper when booked from another country

6. Mix and Match Airlines & One-Way Tickets
Booking round-trips with one airline isn’t always the cheapest option.
- Use sites like Kiwi.com or Skiplagged to combine one-way tickets on different carriers
- Look for “open-jaw” flights (arriving in one city and departing from another)
- Hidden city ticketing (e.g., booking a flight with a layover in your actual destination) can save money, but beware—airlines may penalize frequent use

Flying into one city and out of another can be cheaper—and help you visit multiple places.
- Look for free stopovers offered by airlines like Qatar Airways, Turkish Airlines, or Icelandair
- Use multi-city search features on Google Flights or Skyscanner
- Long layovers in major hubs can significantly reduce your fare—and let you explore a new city for a few hours or overnight

Low fares can quickly turn expensive with baggage, seat selection, and change fees.

10. Use Local Airlines for Regional Travel
In some countries, local budget carriers offer unbeatable deals that don’t always show up on global booking sites.

- Visit airline websites directly for exclusive offers
- Check regional travel forums or local deal sites for promo codes
