We never compare a cheap economy seat against a business fare on a different flight. Economy and business sit side by side on the exact same metal, the same day.
Cabin value, told straight.
FlightGap exists for one decision: on this exact flight, is business worth the money? We put economy and business on the same itinerary, score the gap, and price it per hour, so you can answer in ten seconds, with no card and no signup.
A 0-100 read on whether the upgrade is worth it, blending premium uplift, per-hour cost, seat quality, and historical percentile.
Every fare carries its cost per flight hour, so a 14-hour lie-flat and a 2-hour recliner are judged on the same scale.
We point you straight at the airline or OTA selling the fare, and to Flightpoints when the smarter move is points and miles.
Why we built it
Flight search is great at finding the cheapest seat and terrible at telling you whether to spend more. The upgrade question, pay 3x for a flat bed, usually means opening five tabs and guessing. FlightGap turns that guess into a number, and then hands you off to book it the smartest way.
