FlyInterval
How FlyInterval Compares Flights
What we compare, where the information comes from and what you should verify before booking.
From search rules to travel intervals
You choose the origin, destination, earliest departure, latest return and acceptable stay length. FlyInterval builds the valid departure-and-return intervals inside that window and compares the available flight offers for those rules.
Filters such as currency, stopovers and same-city return are applied consistently to the comparison. One-way searches use departure dates rather than a stay interval.
Prices and flight information
Flight information is supplied by third-party flight-data and booking partners. Results can be cached for performance and may change after they are retrieved. A displayed price is a discovery signal, not a fare guarantee.
The airline or booking provider checkout is authoritative for availability, final price, baggage, fare class, payment currency, connection protection and cancellation terms.
How results are presented
FlyInterval visualises each matching trip as an interval and makes lower-priced options easier to compare. Price is important, but the details also expose flight duration, stops and available warnings so you can judge the complete itinerary.
We do not accept payment or issue tickets. Selecting an offer opens the third-party provider responsible for the booking.
Corrections and transparency
Flight feeds can contain delayed, incomplete or inconsistent information. If you find a reproducible discrepancy, send the route, search dates, currency and a screenshot to [email protected].
