Observe the fare
Fly Frugal records round-trip fares for specific origins, destinations, dates, and trip lengths. Each observation includes its check time.
Methodology and limitations
Flight savings, explained plainly.
Fly Frugal separates the current fare, the evidence that it is unusual, and the flight plan you would actually have to take.
Short answer: a fare becomes a verified saving only when Fly Frugal has a usable usual-price comparison for the same trip. A low price without that comparison remains an observed fare, not a claimed saving.
Verify the saving
When a price-insight source supplies a usable usual-price range, Fly Frugal shows the dollar difference. Without that evidence, it shows only the current fare.
Show the tradeoff
Stops, overnight legs, flight times, airlines, and longest layovers stay visible so a cheap fare is not mistaken for a convenient trip.
Keep alerts restrained
Route alerts compare future checks with the fare recorded when the alert was created or with an optional absolute target.
