Can I just book the cheapest ticket and pay the fee later?

Most 'Basic' or 'Light' tickets are non-changeable and non-refundable. If you cancel, you lose the entire ticket value. Always check the fare class rules before purchasing.

Does booking with a travel agent offer more flexibility?

Generally, no. Travel agents usually have to abide by the same airline fare rules, and they often charge their own service fees for making changes to your booking.

What is a 'fare difference'?

If you change your flight to a new date that is more expensive than your original ticket, you must pay the difference in price. You are only ever 'flexible' on the change fee, not the market price of the seat.

Booking International Flights with Flexible Change Options

To secure flexible international flights, book directly through the airline's website and select the 'Flexible' or 'Premium Economy' fare class. Avoid third-party booking sites, as they complicate changes and often charge additional processing fees on top of airline penalties.

Filter for direct booking. Use Google Flights to search for your route and dates, but always click through to the official airline website to book. Third-party sites (like Expedia or Kiwi) make it nearly impossible to resolve issues if a flight change is needed.
Select the right fare class. Look for labels like 'Flexible,' 'Flex,' or 'Refundable.' These fares allow you to change your dates without paying a change fee, though you will still be responsible for the 'fare difference' if the new flight is more expensive.
Verify change rules before payment. Click the 'Fare Rules' link during the booking process. Look for 'Change Fee: USD 0' or 'Permitted with no fee.' If you don't see this, assume the ticket is restricted.
Consider a 'Cancel for Credit' policy. If you aren't sure of your dates, some airlines offer 'Cancel for Flight Credit' options. This allows you to cancel the booking and receive a voucher for the full value, valid for travel within 12 months.
