About Fare Types
We search many types of fares to find the lowest price for each possible flight itinerary option.
Typically, the lowest-priced fares have many restrictions. These fares usually have penalties for refunds and changes. Most are non-refundable and do not allow changes after the ticket is purchased.
However, when the refundable/changeable only option is chosen, we search only those fares with no penalties. You may notice higher prices for flights with this search.
