Start by using flight comparison websites like Google Flights, Skyscanner, or Kayak to search for the best deals across multiple airlines. Set up price alerts to monitor fluctuations and be ready to book quickly when prices drop. Consider flying on weekdays or during off-peak seasons when fares are typically lower.

Flexibility is key to finding cheap flights
If possible, travel during the week, from Tuesday to Thursday. These are usually the cheapest days to fly. Also, flights in the early morning or late-night periods are generally cheaper because not many passengers travel then. So, use the flexible date feature that many flight search engines offer to find out which days have the best prices.

Consider Alternative Airports
Fly into or out of alternative airports near your destination. Sometimes this can save you hundreds.
Compare prices for nearby airports and balance the cost of ground transportation against possible flight savings.

Set Up Price Alerts
Register for fare alerts via your favorite flight search engine or directly on any airline's website. These price alerts will notify you of any drop in the fare price for the selected route, thus helping you make bookings at the best price. This works well for travelers who have flexibility in their travel plans and can afford to wait for the best deal.

Deals and Special Offers
Keep a tab on the different promos of airlines, flash sales, and limited-time offers. Carriers blatantly post their discounted fares on their websites and social media pages. You might want to consider joining airline loyalty programs or signing up for newsletters to get exclusive offers and discounts.
