Start with the trip
Search current authorized sources.
Choose real dates, travelers, cabin, and bags. FareSift keeps live offers separate from recently observed prices.
Keep tickets protected
If an itinerary uses separate tickets, the transfer and missed-connection exposure should remain explicit.
Account for the return rules
Changes, refunds, seats, and baggage can materially change which fare is the better purchase.
A fare is current only when the live source confirms it.
Compare complete trip cost Recently observed prices are planning evidence—not bookable inventory, complete-party availability, or verified savings.
