Money-Saving Tips & Strategies
- Be Flexible with Dates: Use the “+/- 3 days” search feature on platforms like Kiwi.com to find the cheapest flights. Sometimes, shifting your travel dates by even a day or two can result in significant savings.
- Consider Nearby Airports: Check for flights to nearby airports, especially in larger cities. These can sometimes offer lower fares.
- Compare with Budget Airlines: Make sure to compare prices with budget airlines, as they often have lower base fares, but always factor in extra fees for baggage and seat selection.
- Sign Up for Price Alerts: Set up price alerts on Aviasales and other platforms to be notified when prices drop.
- Look for Hidden Fees: Always review the total price, including baggage fees, seat selection, and other add-ons. Some platforms, like Kiwi.com, provide upfront transparency regarding potential extra costs.
- Use Cashback Programs: Consider using WayAway or similar platforms that offer cashback rewards on flight bookings to earn money back on your purchases.
- Book in Advance (or Not): Booking in advance can sometimes offer better deals, but last-minute flights can also be cheaper, particularly for off-peak travel. Monitor prices and be ready to take advantage of price drops.
Common Mistakes to Avoid
- Not Comparing Multiple Sites: Don’t rely on a single comparison site. Always compare prices across several platforms, including Aviasales , Kiwi.com, and Trip.com, to ensure you're getting the best deal.
- Ignoring Hidden Fees: Always check for baggage fees, seat selection costs, and other potential add-ons. Read the fine print before booking.
- Booking Without Flexibility: If your travel dates are fixed, you might miss out on better deals. Consider being flexible with your travel dates if possible.
- Not Checking Airline Websites Directly: While comparison sites are useful, always check the airline's website directly, as they may offer special deals or promotions.
- Focusing Solely on Price: Consider other factors like flight duration, layover times, and airline reputation before making your final decision.
