Money-Saving Tips & Strategies

  • Be Flexible with Dates: Use flexible date search tools on platforms like Kiwi.com to find the cheapest days to fly. Even a day or two difference can significantly impact the price.
  • Compare Across Multiple Sites: Always compare prices on multiple platforms, including Trip.com, Aviasales, and others, as prices can vary.
  • Consider Budget Airlines: Look into budget airlines that service your route. Be sure to factor in extra fees for baggage and other services.
  • Book in Advance, But Not Too Early: Generally, booking 2-6 months in advance offers the best balance of price and availability for international flights. However, always monitor prices, as fares can change.
  • Use Cashback Programs: Sign up for cashback programs like WayAway to get a percentage of your money back on flights and other travel expenses.
  • Set Price Alerts: Utilize price alerts on your chosen booking sites to monitor fare fluctuations and snag deals as they arise.
  • Consider Hidden City Ticketing: (Use cautiously). Fly to your intended destination via a connecting flight, even if the connecting city is your actual destination. This can sometimes result in cheaper fares, but it is not always advisable, and may violate airline policies.

Common Mistakes to Avoid

  • Ignoring Hidden Fees: Always check for extra fees for baggage, seat selection, and other services. These can significantly increase the total cost of your flight.
  • Booking Too Late or Too Early: Booking at the wrong time can lead to higher prices. Aim for the sweet spot of 2-6 months in advance.
  • Not Comparing Prices: Relying on a single booking site can cause you to miss out on better deals. Compare prices across multiple platforms to find the best option.
  • Failing to Read the Fine Print: Always review the terms and conditions, including cancellation policies, change fees, and baggage allowances, before booking.
  • Not Considering Travel Insurance: Travel insurance is a worthwhile investment, especially for international travel, as it protects you against unforeseen events such as flight cancellations, medical emergencies, or lost luggage.

Traveler Rights & Compensation

If your flight is delayed or cancelled, you may be entitled to compensation. For delays and cancellations, understand your rights, and know how to make a claim. Be aware of regulations, such as those in the EU, and seek compensation through services like AirHelp. They can help you navigate the claims process and seek compensation on your behalf. Always keep all relevant documentation (boarding passes, flight confirmations, etc.) to support your claim.
