Here are 10 insider tips to help you find the cheapest flights:

1. Be flexible with your travel dates: Prices can vary significantly depending on the day of the week and time of year. Consider flying on weekdays or during off-peak seasons to get better deals.
2. Use flight comparison websites: Websites like Skyscanner, Kayak, and Google Flights allow you to compare prices across multiple airlines and find the best deals. They often have features that show you the cheapest days to fly.
3. Sign up for fare alerts: Many airlines and travel websites offer fare alerts that notify you when prices drop for specific routes. Signing up for these alerts can help you snag great deals.
4. Consider alternative airports: Flying into or out of smaller airports near your destination can sometimes be cheaper than using major airports. Check for nearby airports and compare prices.
5. Be open to layovers: Non-stop flights are usually more convenient, but they can also be more expensive. Consider flights with layovers as they often come at a lower cost. Just make sure to leave enough time between flights.
6. Book in advance: Generally, booking your flight several months in advance can help you secure lower prices. Last-minute bookings are usually more expensive, so plan ahead if possible.
7. Clear your browser cookies: Some travel websites track your browsing history and may show you higher prices based on your previous searches. Clearing your cookies or using incognito mode can help you see the true prices.
8. Consider budget airlines: Budget airlines often offer lower fares compared to traditional carriers. While they may have fewer amenities, they can be a great option for travelers on a tight budget.
9. Be aware of additional fees: When comparing flight prices, take into account additional fees such as baggage fees, seat selection fees, and in-flight meal charges. Sometimes a seemingly cheaper flight can end up being more expensive after factoring in these fees.
10. Be patient and persistent: Finding the cheapest flights requires time and effort. Prices can fluctuate daily, so keep checking fares and be ready to book when you find a great deal.

By following these insider tips, you'll increase your chances of finding the cheapest flights for your next trip!
