The per-hour cost sort changed how I shop premium cabins on long-haul. SQ Business at $236/hr versus $310/hr on a competitor. That is the whole pitch.
GapScore is not a gimmick. A 91 on DXB-BKK predicted exactly what an Apex Suite ride should cost. Methodology drawer earned my trust.

Questions, answered.
Same-flight match, GapScore, per-hour cost. We use a few new terms. Here is what each one means.
What is GapScore?
GapScore is a 0 to 100 rating that tells you how good a business upgrade is on a given flight. It mixes five things: premium uplift (30%), per-hour cost (25%), seat quality (20%), where today's price sits in the last 90 days (15%), and how well the match fits (10%). 85 and up is a strong upgrade. Below 55, stick with economy.
What does 'per-hour cost' mean?
Per-hour cost is the cabin price divided by flight time in hours. A $1,418 business fare on a 6-hour flight is $236/hr. This makes short and long flights easy to compare. A $200/hr lie-flat on a 12-hour red-eye is a better deal than a $400/hr recliner on a 3-hour hop. No other flight search sorts this way.
What is a 'same-flight match'?
We only show a comparison when economy and business are on the exact same flight: same flight number, same date, same airline. If a route has business on a different operator or routing, we do not fake it. The card is hidden or marked 'closest comparable'. That rule is the whole product.
What is the 'gap' in FlightGap?
The gap is the price difference between economy and business on the same flight. We show it three ways: dollar delta, percent uplift, and per-hour spread. All three sit on every comparison card next to the GapScore.
How is GapScore calculated?
Each input is normalized per route before we weight it. Premium uplift is compared to the route's 90-day median. Per-hour cost is checked against the same cabin tier on similar-length flights. Seat quality comes from our cabin dictionary. Historical percentile shows where today's price sits in the last 90 days. Confidence drops the score if the match is not exact.
Compare, Economy only, Business only. What is the difference?
Compare shows results only where economy and business are on the same flight, with the side-by-side delta and GapScore. Economy only shows economy fares for the route. Business only shows business fares for the route. The same row of filters works on all three.
How fresh are the prices?
We cache each route and date for 72 hours, then pull live prices at search time. Every result card has a freshness timestamp. Prices can move between when we cached and when you click through, so always check the final price on the airline or OTA page before you pay.
Does FlightGap book the flight?
No. FlightGap is a search and comparison tool. Each result links to the airline or OTA that is selling the fare. You complete the booking there. We never hide the source.
Is FlightGap free?
Yes. Search, side-by-side cabin compare, GapScore, and per-hour cost are free. No card, no signup. Premium is $49 a year and Elite is $199 a year. Those tiers add saved alerts, 12 months of price history, and the flightpoints.com award-miles overlay.
Why does the price differ from the airline's site?
Prices move all day in airline systems, so a cached price can lag for a few minutes. Some OTAs also list a lower price than the airline direct. The link on each card is the price source. That page is the one to trust at click time.
