Same-flight uplift varies wildly by geography. Below is the working map of where business sits versus economy on each major corridor. The numbers update with each quarterly Gap Index.
The biggest weekly volume of same-flight business inventory. La Compagnie, TAP Portugal, Aer Lingus, and shoulder-season BA / Iberia sales drive the lowest gaps. Avoid Friday departures from US East Coast — they price like full business.
Originating from the Gulf is structurally cheaper than originating in the US or UK. Emirates, Etihad, Qatar, Oman Air, Saudia, and Gulf Air all run lie-flat 1-2-1 on the workhorse lanes. Mid-week off-peak is where the gap collapses.
Regional lie-flat is common (SQ, JL, NH, CX). Short hops (HKG ↔ SIN, BKK ↔ NRT) often land at 1.5x in low season. The cabin product is full long-haul business on most of these routes, not a domestic-style recliner.
The clearest value frontier from the US. LATAM, Avianca, and Copa all sell lie-flat 1-2-1 at fares that often beat US transcontinental business.
Sources matter. From Tokyo / Seoul / Singapore the gap is far smaller than from US West Coast. Premium Japanese carrier sales (JAL, ANA) on the Pacific often beat US legacies on the same lane.
The worst-value region globally. Useful as a benchmark, not a target. Mistake fares from third-country origins (e.g., DEL ↔ MEL via QR) sometimes break the pattern.
Every day. Each card shows the most recent same-flight business uplift we observed on the route. Click through to a live search to see today's cabin prices on tomorrow's date with a ±3 day flex.
Two filters. First, the route must have a meaningful same-flight match (economy and business on the same flight number). Second, the route has to carry enough weekly volume that the gap data is statistically stable, not a one-off mistake fare.
Most carriers price each leg from a different revenue zone. Originating in Dubai, Doha, Bangkok, Mumbai, or Singapore often saves 30 to 60% on the same metal compared to originating in the US. The Routes corridors page is built around this lever.
Opening a route card sends you into a search with the depart date set to the next default date and a 3-day window on either side. That window catches the typical weekly fare-bucket dip without blowing up the result count.
If a route does not currently publish economy and business on the same flight number, it cannot be a same-flight match. We will not fake the comparison. The route may still show in the search as Economy only or Business only, which is the right answer when no pairing exists.
